I live in a village where every route back home is up hill. I went to the very interesting and very exciting Fully Charged Live show, all about renewable energy and low emission vehicles, such as electric cars. One of the areas there was about electric bicycles and electric skateboards and mountain boards. My brother loved the electric boards - he&#39;s a kite surfer and snowboarder, so he took to it straight away. I really, really liked the e-bikes. When I got home I checked out a local bike shop, borrowed an e-bike, sailed up the hill home with ease and bought the mountain bike version. It is fantastic.&lt;br /&gt;&lt;br /&gt;I&#39;m happy with how courteous and respectful most drivers are, but there&#39;s always a few idiots and it only takes one to cause a serious problem, so I like to get off the roads. I&#39;ve been wandering the paths and tracks near home on my new bike and loving the fact that hills are now not obstacles but instead are fun.&lt;br /&gt;&lt;br /&gt;Today I followed a route I&#39;ve walked and cycled for years and I thought I knew very well, but as usual, when you take a close look at familiar things new stuff emerges. Mapping makes you look closely.&lt;br /&gt;&lt;br /&gt;I have the file of Public Rights of Way that the East Riding of Yorkshire council have finally released under OGLv3. I am grateful to Robert Whittaker for his persistent and skillful chasing of the council. He got the data released under the open licence where I had failed.&lt;br /&gt;&lt;br /&gt;In general the data shows where rights of way are present and shows the footpaths, bridleways and byways as expected. Today I followed a route which used various rights of way and all were signed with the yellow and green arrows and some fingerboards all put up by the council. You would expect these signs on the ground to match the data in the file from the council, but no.&lt;br /&gt;&lt;br /&gt;There is a part of Elloughton Dale where the path drops down a steep slope to the road through the valley. You can then follow the road for a couple of hundred metres before turning off to climb the other side of the valley. The descent is through woods and is steep enough that steps with wooden risers have been cut to prevent erosion. This however is not the route I took, because there is a more direct route that comes out of the woods opposite the point where the ascent starts, thus it avoids the steps and there is no need to use the road except to cross it. When I first used this more direct route, probably forty years ago, it was unofficial and the land owner put up barbed wire to stop it being used, but after a while a gate appeared instead (he was probably fed up with replacing the wire) and this was the preferred route to take. More recently, at least twenty five years ago, public right of way signs appeared both at the roadside and at the point in the woods where the route down the steps and this newer route diverge.&lt;br /&gt;&lt;br /&gt;This new route is not part of the data the East Riding of Yorkshire council publish and it is not on their &#39;Walking the Riding&#39; map they publish on their website. So which to believe, council signs on the ground or the data they reluctantly published? Maybe their reluctance to publish was partly because they know the data is out of date. I have used what I know on the ground to map the route, though I can&#39;t add a prow_ref tag because that&#39;s not displayed on any of the signs.&lt;br /&gt;&lt;br /&gt;&lt;table cellpadding=&quot;0&quot; cellspacing=&quot;0&quot; class=&quot;tr-caption-container&quot; style=&quot;float: left; text-align: right;&quot;&gt;&lt;tbody&gt;&lt;tr&gt;&lt;td style=&quot;text-align: center;&quot;&gt;&lt;a href=&quot;https://2.bp.blogspot.com/-K6dYvHpTfbM/W5uatKctewI/AAAAAAAADa8/DxrSPNW80pU69tXrsAR7wzfIEqe2Gjf8wCLcBGAs/s1600/IMG_20180914_102451.jpg&quot; imageanchor=&quot;1&quot; style=&quot;clear: right; margin-bottom: 1em; margin-left: auto; margin-right: auto;&quot;&gt;&lt;img border=&quot;0&quot; data-original-height=&quot;1600&quot; data-original-width=&quot;1200&quot; height=&quot;320&quot; src=&quot;https://2.bp.blogspot.com/-K6dYvHpTfbM/W5uatKctewI/AAAAAAAADa8/DxrSPNW80pU69tXrsAR7wzfIEqe2Gjf8wCLcBGAs/s320/IMG_20180914_102451.jpg&quot; width=&quot;240&quot; /&gt;&lt;/a&gt;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td class=&quot;tr-caption&quot; style=&quot;text-align: center;&quot;&gt;Hawthorn looking good&lt;/td&gt;&lt;/tr&gt;&lt;/tbody&gt;&lt;/table&gt;It has rained recently, but the long, dry summer means that there&#39;s hardly any sign of damp on the&lt;br /&gt;&lt;table cellpadding=&quot;0&quot; cellspacing=&quot;0&quot; class=&quot;tr-caption-container&quot; style=&quot;float: right; margin-left: 1em; text-align: right;&quot;&gt;&lt;tbody&gt;&lt;tr&gt;&lt;td style=&quot;text-align: center;&quot;&gt;&lt;a href=&quot;https://3.bp.blogspot.com/-pudfx02232A/W5uat3vl_KI/AAAAAAAADbA/x2v5_pWANfU4urmqA_OtTGAOVZPU7KRmgCLcBGAs/s1600/IMG_20180914_102818.jpg&quot; imageanchor=&quot;1&quot; style=&quot;clear: right; margin-bottom: 1em; margin-left: auto; margin-right: auto;&quot;&gt;&lt;img border=&quot;0&quot; data-original-height=&quot;1600&quot; data-original-width=&quot;1200&quot; height=&quot;320&quot; src=&quot;https://3.bp.blogspot.com/-pudfx02232A/W5uat3vl_KI/AAAAAAAADbA/x2v5_pWANfU4urmqA_OtTGAOVZPU7KRmgCLcBGAs/s320/IMG_20180914_102818.jpg&quot; width=&quot;240&quot; /&gt;&lt;/a&gt;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td class=&quot;tr-caption&quot; style=&quot;text-align: center;&quot;&gt;No fruit on the brambles&amp;nbsp;&lt;/td&gt;&lt;/tr&gt;&lt;/tbody&gt;&lt;/table&gt;&lt;table align=&quot;center&quot; cellpadding=&quot;0&quot; cellspacing=&quot;0&quot; class=&quot;tr-caption-container&quot; style=&quot;float: right; margin-left: 1em; text-align: right;&quot;&gt;&lt;tbody&gt;&lt;tr&gt;&lt;td style=&quot;text-align: center;&quot;&gt;&lt;a href=&quot;https://3.bp.blogspot.com/-NngsGNxXScc/W5uaswfrTvI/AAAAAAAADa0/Gy7f7u9UceYqowQENmjETeWYFn3OzfeAQCLcBGAs/s1600/IMG_20180914_102612.jpg&quot; imageanchor=&quot;1&quot; style=&quot;clear: left; margin-bottom: 1em; margin-left: auto; margin-right: auto;&quot;&gt;&lt;img border=&quot;0&quot; data-original-height=&quot;1600&quot; data-original-width=&quot;1200&quot; height=&quot;320&quot; src=&quot;https://3.bp.blogspot.com/-NngsGNxXScc/W5uaswfrTvI/AAAAAAAADa0/Gy7f7u9UceYqowQENmjETeWYFn3OzfeAQCLcBGAs/s320/IMG_20180914_102612.jpg&quot; width=&quot;240&quot; /&gt;&lt;/a&gt;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td class=&quot;tr-caption&quot; style=&quot;text-align: center;&quot;&gt;Elder looking shrivelled&lt;/td&gt;&lt;/tr&gt;&lt;/tbody&gt;&lt;/table&gt;ground. In the woods the ground is dry and even dusty in places and very few muddy spots even in places that are usually muddy. All this dry weather has taken its toll on wild fruit, but some more so than others. Bullaces seem a bit small but are abundant, hawthorn looks to be a fairly average number and a good size. Elder has few berries and they are small and many shrivelled one. The big loser this year are brambles (blackberries). There is hardly a single fruit to be seen with all the remnants of flowers hardly showing as any berries at all. Any wildlife that usually feasts on the masses of brambles around the paths and tracks here will have a to find something else if they want to survive.&lt;br /&gt;&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;&lt;/div&gt;&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;&lt;/div&gt;</description><link>http://chris-osm.blogspot.com/2018/09/rights-of-way-and-fruit.html</link><author>noreply@blogger.com (Unknown)</author><media:thumbnail xmlns:media="http://search.yahoo.com/mrss/" url="https://2.bp.blogspot.com/-K6dYvHpTfbM/W5uatKctewI/AAAAAAAADa8/DxrSPNW80pU69tXrsAR7wzfIEqe2Gjf8wCLcBGAs/s72-c/IMG_20180914_102451.jpg" height="72" width="72"/><thr:total>0</thr:total></item><item><guid isPermaLink="false">tag:blogger.com,1999:blog-179325926611299376.post-7982025667568608764</guid><pubDate>Tue, 07 Mar 2017 22:38:00 +0000</pubDate><atom:updated>2017-03-07T22:38:25.724+00:00</atom:updated><title>Have you moved ...</title><description>... or was it just your postcode?&lt;br /&gt;&lt;br /&gt;The new open version of GB postcodes has some strange anomalies in it.

Most that have moved have moved less than 20 metres but 1,520 have moved 500m or more. There are 15 that have moved more than 10km, with the furthest moving over 62km.&lt;br /&gt;&lt;br /&gt;The source of these open postcodes have changed, maybe the process that generates them has a problem in it.

The UK Office of National Statistics provide all kind of open data under the Open Government Licence and one of these is a list of postcode centroids for Great Britain. The dataset includes the date a postcode was added.&amp;nbsp;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;When an area is quite well mapped it needs to be kept up-to-date. A mapper may have visited somewhere to map it when it&#39;s not normally somewhere she might visit, so any new developments might not get mapped as it is built. These new developments all get new postcodes, so showing a map with all the recently added postcodes might help mappers find places that need another survey.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;I&#39;ve put together a map that shows all of the postcodes added since the beginning of 2016. You can see it here&amp;nbsp;&lt;a href=&quot;http://pcdates.raggedred.net/#10/52.7159/-1.3149&quot;&gt;http://pcdates.raggedred.net/#10/52.7159/-1.3149&lt;/a&gt;. &amp;nbsp;There would be quite a lot of markers in some areas so I use the excellent MarkerCluster plugin to make the markers more manageable. Each marker is a single centroid. If you click on it it shows a popup with the postcode and start date in it.&amp;nbsp;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;If it is useful please let me know what you think. Would you like anything changed? If people like it I will maintain it as each new release of postcode data &amp;nbsp;id available, which is currently four times each year.&lt;/div&gt;</description><link>http://chris-osm.blogspot.com/2017/03/new-postcodes.html</link><author>noreply@blogger.com (Unknown)</author><thr:total>4</thr:total></item><item><guid isPermaLink="false">tag:blogger.com,1999:blog-179325926611299376.post-4938906376465446899</guid><pubDate>Sat, 04 Mar 2017 12:25:00 +0000</pubDate><atom:updated>2017-03-04T16:18:53.422+00:00</atom:updated><title>Postcode changes</title><description>I have provided a tile layer of postcode centroids based on the Codepoint Open postcodes since they were first published in 2010. I also provide a similar layer for postcodes based on the Office of National Statistics dataset called ONSPD. I have just updated the two layers with the recently updated data.&lt;br /&gt;&lt;br /&gt;The ONSPD dataset contains almost a million more records than the Codepoint Open one. Most of these extra codes are retired postcodes. There are also some entries for BT codes. These are Northern Irish postcodes which are not released under OGL, so I don&#39;t publish them - I wouldn&#39;t want them to be used as a source for Northern Irish postcodes in OSM as that would violate their copyright. There are some IM codes, but without any coordinates. These are Isle of Man codes. I don&#39;t believe they are released under an open licence so again I don&#39;t publish them, but having no coordinates makes them useless for this purpose anyway. &lt;br /&gt;&lt;br /&gt;The ONSPD dataset has a column for the start date and one for the end date. The earliest start date (just year and month) seems to be 1996-06 which most active postcodes have, the most recent start date is 2017-01.&lt;br /&gt;&lt;br /&gt;Edit: The spread of dates is much wider than I first thought, with the earliest is 1973-08.&lt;br /&gt;&lt;br /&gt;I think showing any newly added postcodes would be useful to help people see where there may be new developments that need surveying. Some new postcodes will just be yet another code on a building that already has many postcodes. These are places that get lots of post (after all that&#39;s what postcodes are for), often royal mail buildings where there are PO Box addresses.&lt;br /&gt;&lt;br /&gt;The recently published files have changed their formats (again). Now the Codepoint Open dataset has fixed length postcode fields, so the natural spacing is lost unless they are reformatted, which is very easy. In the past the list of postcodes from Codepoint Open exactly matched the processed list of postcodes from ONSPD, now they don&#39;t. I&#39;m examining what it is that is different.&lt;br /&gt;&lt;br /&gt;Many of the centroids have moved a few metres. I can understand that a centroid might move if the street or section of street had some new houses (delivery points) added or removed, but that is not the cause of most of the changes. It seems the reason for the change is that the source of the centroids has changed. The data used to come from Address Point (which is now discontinued), now it comes from the Postal Address Location Feed of Geoplace. This is interesting because it removes the connection with Royal Mail and gets the postcode from local authority data. Local authorities are where addresses are created, though Royal Mail must have a part to play in adding the postcode. Getting the data from Geoplace may be one small step towards releasing UK address data as open data. I hope so.&lt;br /&gt;&lt;br /&gt;To see how to use the tile layers follow the links for &lt;a href=&quot;http://codepoint.raggedred.net/&quot; target=&quot;_blank&quot;&gt;Codepoint Open&lt;/a&gt; and &lt;a href=&quot;http://onspd.raggedred.net/&quot; target=&quot;_blank&quot;&gt;ONSPD&lt;/a&gt;.&lt;br /&gt;&lt;br /&gt;Edit:&lt;br /&gt;I have discovered there are 111 postcodes in the Codepoint Open dataset that are not in the ONSPD dataset after I have processed it. These are &#39;large user&#39; postcodes and they don&#39;t have useful coordinates. In the Codepoint Open dataset there is a field called positional quality indicator. 10 indicates the best positional quality, 90 indicates the worst. All 111 are 90. In future I&#39;ll ignore these entries.</description><link>http://chris-osm.blogspot.com/2017/03/postcode-changes.html</link><author>noreply@blogger.com (Unknown)</author><thr:total>0</thr:total></item><item><guid isPermaLink="false">tag:blogger.com,1999:blog-179325926611299376.post-8944826039361377599</guid><pubDate>Thu, 26 Jan 2017 15:43:00 +0000</pubDate><atom:updated>2017-01-26T16:09:25.735+00:00</atom:updated><title>Go Pokémon</title><description>I&#39;m always keen to see new contributors to OSM. They bring details that interest them to OSM, be it their local area, their sport, their hobby, their work or whatever. Having an open tagging scheme that allows all kinds of objects to be mapped is part of the strength of OSM.&lt;br /&gt;&lt;br /&gt;I follow new mappers in my area and sometimes add comments to their changesets or send them a welcome message. Sometimes a new mapper adds one thing and never adds more, sometimes they add one type of thing over wide areas. One thing the East Riding of Yorkshire needs is more fine detail of rural footpaths and bridleways. A few new mappers appeared starting to add footways and I was encouraged that this may spread. Sadly I was wrong and what I hoped was something useful is turning into something less so.&lt;br /&gt;&lt;br /&gt;It seems that someone has discovered that some details in OSM may be being used in Pokémon Go, the virtual reality game by Niantic to find imaginary creatures. These imaginary creatures appear more near water and in parks near footpaths. The new mappers were adding footpaths in parks to encourage these beasties to appear. Their new footpaths were in good places and were welcome, but then word spread.&lt;br /&gt;&lt;br /&gt;People then started adding more parks and ponds. Some were real parks and ponds that were just missing from the map, but some were plonked anywhere, over existing buildings and roads, over schools or whatever. A few people realised that changing existing areas&#39; tagging was easier, so suddenly a building becomes a park or a pond.&lt;br /&gt;&lt;br /&gt;It is not clear to me that Niantic are using OSM data, but if they are, adding phoney stuff won&#39;t work very well because it will be found and cleaned up quickly. If Niantic are using OSM data they will probably only incorporate changes to OSM data occasionally, if at all.&lt;br /&gt;&lt;br /&gt;It&#39;s great to see new mappers. Maybe a few will become more interested in mapping than Pokémon. All the real parks, paths and waterways that are being added are all helpful. Tidying up the junk is nuisance but maybe I&#39;ll spot other stuff to improve too.&lt;br /&gt;&lt;br /&gt;Back to the new users feed. Oh, there&#39;s another one ...</description><link>http://chris-osm.blogspot.com/2017/01/go-pokemon.html</link><author>noreply@blogger.com (Unknown)</author><thr:total>0</thr:total></item><item><guid isPermaLink="false">tag:blogger.com,1999:blog-179325926611299376.post-7341319206121853848</guid><pubDate>Mon, 12 Dec 2016 14:05:00 +0000</pubDate><atom:updated>2016-12-12T15:18:18.030+00:00</atom:updated><title>Leaflet plugin</title><description>&lt;div class=&quot;tr_bq&quot;&gt;I have been trying to replace a long-standing map based on the OpenLayers 2 library to LeafletJS. The main sticking point was that OpenLayers has a useful permalink function that changes the URL to include a query string that identifies the map location and which layers should be shown.&amp;nbsp;&lt;/div&gt;&lt;br /&gt;Leaflet has a neat plugin to &lt;a href=&quot;https://github.com/mlevans/leaflet-hash&quot;&gt;show the location as a hash&lt;/a&gt; but that doesn&#39;t include the layers to show. After a bit of investigation I decided to try to write a Leaflet plugin to make all this easier.&lt;br /&gt;&lt;br /&gt;If a map has optional base layers and some overlays it often will use the Layers control to make the choices easy to select. The layers are not easily accessible from the map object as only the currently displayed layers, not the hidden ones, are available. The Layers control has access to all the layers, but that control is not accessible from the central map object. The only way to have access to all of the layers is from the Layers control, so a new control, inherited from the Layers control seemed to be the right answer. HashLayers control was developed.&lt;br /&gt;&lt;br /&gt;HashLayers does all that the Layers control does, of course, but adds the functionality of the URL hash. The hash looks like this:&lt;br /&gt;&lt;blockquote class=&quot;tr_bq&quot;&gt;&lt;span style=&quot;background-color: #eeeeee;&quot;&gt;#zoom/longitude/latitude/layers&lt;/span&gt;&lt;/blockquote&gt;This gets appended to the URL of the page that the map is on. Using the hash means the position and layers can be changed dynamically as the map is zoomed or scrolled around and as different layers are selected. Changing the hash value of a URL doesn&#39;t force a reload of the page and doesn&#39;t show up in browser history. &lt;br /&gt;&lt;br /&gt;The zoom is the current zoom level and longitude and latitude are the centre of the map. The layers is a string representing the base layers and any overlays. If a base layer is selected &#39;B&#39; is shown, &#39;O&#39; shows an available base layer not selected. The overlays are shown as a string of &#39;T&#39; or &#39;F&#39; (true or false) showing if they are shown or not. A typical hash might be:&lt;br /&gt;&lt;blockquote&gt;&lt;span style=&quot;background-color: #eeeeee;&quot;&gt;#12/-0.393105/53.775095/BOFFTF&lt;/span&gt;&lt;/blockquote&gt;&amp;nbsp;This has the first base layer visible, the second one not showing and four overlays available, but with only the third one visible. These selections will be reflected in the visible selection control too.&lt;br /&gt;&lt;br /&gt;If a map is created with the HashLayers control on it and a hash is passed in the URL, the map will centre on the location and zoom specified and show the requested layers. If no hash is passed then the default location and zoom will be used from the setView() or map options as normal. Layers will be shown as they were added to the map. A hash to reflect all this will be appended to the URL which gets updated with every change. There is no need for the OpenLayers permalink control.&lt;br /&gt;&lt;br /&gt;I now need to test it more carefully and decide if it is worth publishing as a Leaflet plugin.</description><link>http://chris-osm.blogspot.com/2016/12/leaflet-plugin.html</link><author>noreply@blogger.com (Unknown)</author><thr:total>2</thr:total></item><item><guid isPermaLink="false">tag:blogger.com,1999:blog-179325926611299376.post-1259980533065737603</guid><pubDate>Sat, 03 Dec 2016 23:56:00 +0000</pubDate><atom:updated>2016-12-04T00:03:30.051+00:00</atom:updated><title>Replacing OpenLayers</title><description>When OS released their Open Data I created a simple map that showed a few of their offerings as overlays on an OSM base layer &lt;a href=&quot;http://oscompare.raggedred.net/&quot;&gt;oscompare.raggedred.net&lt;/a&gt;. At the time my maps were driven by OpenLayers. OpenLayers v2 works well but is a lot harder to use than LeafletJS. As soon as Leaflet arrived I started to use that and it has only got better as time has passed. There is OpenLayers v3 available I think, but I doubt I&#39;ll use it.&lt;br /&gt;&lt;br /&gt;OpenLayers has a permalink option that changes the URL in the browser to include a query string describing the location of the centre of the map and the zoom level. This lets you bookmark or send a link that will open the map in the right place. Leaflet has a plugin to create a hash on the URL that does a similar thing. &amp;nbsp;It works well but there is a bit of a problem.&lt;br /&gt;&lt;br /&gt;The OpenLayers permalink adds a &#39;layers=&#39; bit to the URL. An example would be BOTFF. This means the first base layer is shown and not the second one, then the first overlay is visible but not the second or third. This great, because not only does the URL make map show the right place, but the overlay you wanted to show will also appear too. Leaflet&#39;s hash plugin doesn&#39;t do this and that is a problem for me.&lt;br /&gt;&lt;br /&gt;I decided to replace the map showing the OS overlays using Leaflet. It was quick to do and works well, but I can&#39;t use it as the replacement for the OpenLayers map because Leaflet doesn&#39;t have a built-in way to show the layers that were selected. People link to my map, according to the logs, with the query string to select the place and layers. If I just replaced it with the Leaflet-based map their links would all fail. They couldn&#39;t create a new bookmark that includes the layers to show either. I decided to fix this.&lt;br /&gt;&lt;br /&gt;I looked into the documentation for the latest version of Leaflet (1.0.2 at the time of writing). The documentation is very useful. If there are overlays on a map a layers control can be added that allows the overlays to be selected. There can also be more than one base layer that the control allows you to select.&lt;br /&gt;&lt;br /&gt;I thought about a generic way to create a similar effect to the OpenLayers permalink. For a one-off map I can code up the layers to do as I need, but a generic version would be useful. I can get at the layers that a map is currently showing, but Leaflet&#39;s way of hiding a layer is to remove it from the map. The definition of that layer is then not accessible from the map object. I couldn&#39;t see how to find the list of layers including the ones not displayed. The layers control has a list of the layers it uses, which would be ideal, but I couldn&#39;t find any way to find a a reference to that from the map object. There doesn&#39;t seem to be any way to find any controls from the map object. A map method that returns a list of controls might be useful.&lt;br /&gt;&lt;br /&gt;So far I have created a bespoke version of the Leaflet map I wanted. It will accept an OpenLayers-style URL, display the map and create a Leaflet-style URL. I&#39;m thinking about how to duplicate the OpenLayers feature more generically. I have ideas ...</description><link>http://chris-osm.blogspot.com/2016/12/replacing-openlayers.html</link><author>noreply@blogger.com (Unknown)</author><thr:total>0</thr:total></item><item><guid isPermaLink="false">tag:blogger.com,1999:blog-179325926611299376.post-302540053856758893</guid><pubDate>Mon, 14 Nov 2016 23:10:00 +0000</pubDate><atom:updated>2016-11-15T09:04:50.748+00:00</atom:updated><title>A Map in an App</title><description>Maps come in all shapes and sizes. I&#39;ve made maps for a few different uses and since Openstreetmap came along there&#39;s always been some part of OSM in my maps. I offered to make a map for &lt;a href=&quot;http://www.clockenflap.com/&quot;&gt;Clockenflap Music and Arts Festival&lt;/a&gt; in Hong Kong, so I expected to use OSM as the base. What I&#39;ve ended up with uses the tools to create and display the map: JOSM, osm2pgsql, Tilemill, Mapnik and Leaflet, but none of OSM&#39;s greatest asset, its data.&lt;br /&gt;&lt;br /&gt;Clockenflap, like most festivals, is largely a temporary venue. This year it&#39;s a new venue to Clockenflap on the &lt;a href=&quot;http://www.openstreetmap.org/#map=17/22.28401/114.16299&quot;&gt;Central Harbour-front Event Space&lt;/a&gt;. I looked at the area on OSM and how to map the temporary stuff that the event will put up. There&#39;s seven stages, food stalls, bars, attractions, art installations and all the usual support stuff like toilets, first aid and entrance and exit gates. That&#39;s a lot of stuff to add to OSM temporarily. Worst of all, when I started to look at it the site design was still not fixed. I quickly decided that it needed to be stored locally and not uploaded to OSM at all.&lt;br /&gt;&lt;br /&gt;The map is embedded in an app, which I&#39;m not writing. The idea is to run the map in a Webview with a JavaScript Leaflet-based display and it works well. The map has a base layer with all the services on it and layers of overlays with icons that can be clicked. In the apps (one iOS and one Android) the JavaScript in the Webview calls a native iOS or Android function when an icon is touched.&amp;nbsp; So instead of a web popup the app can respond with a dialog or a more detailed response. For example, if a stage icon is touched the app can show what acts are on the stage now and on next.&amp;nbsp; The reverse is true too. For example, if the user scrolls through the list of food suppliers in the app and chooses one, the map is called and shows where the food stall is on the site. I can&#39;t show the apps yet, but a working example of the map is &lt;a href=&quot;http://clockenflap.raggedred.net/&quot;&gt;here&lt;/a&gt;.&lt;br /&gt;&lt;br /&gt;The festival team provided the icons and the look of the map. I think it looks very good. There are sponsors who need to see their logos and colour schemes and the map needs to reflect this, as well as being useful for getting around on a site that no one knows their way around because it is only a day or two old. &lt;br /&gt;&lt;br /&gt;A few things are quite different from most of the maps I&#39;ve made before. Driving the map from a phone screen is a challenge.&amp;nbsp; Trying to get specific icons on the map so they are big enough to read on smaller screen, but don&#39;t overlap too much is tricky. At the lowest zoom level (17) very little is shown by default. If all the overlays are show it is a jumble, there&#39;s just no choice.&lt;br /&gt;&lt;table align=&quot;center&quot; cellpadding=&quot;0&quot; cellspacing=&quot;0&quot; class=&quot;tr-caption-container&quot; style=&quot;margin-left: auto; margin-right: auto; text-align: center;&quot;&gt;&lt;tbody&gt;&lt;tr&gt;&lt;td style=&quot;text-align: center;&quot;&gt;&lt;a href=&quot;http://clockenflap.raggedred.net/&quot; imageanchor=&quot;1&quot; style=&quot;margin-left: auto; margin-right: auto;&quot;&gt;&lt;img border=&quot;0&quot; height=&quot;226&quot; src=&quot;https://2.bp.blogspot.com/-Wmv7Vb1IYsU/WCo_zEFb46I/AAAAAAAAChQ/430qu4-sRo0YoDkVO4fp1dCautm03PyjQCLcB/s400/jumble.png&quot; width=&quot;400&quot; /&gt;&lt;/a&gt;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td class=&quot;tr-caption&quot; style=&quot;text-align: center;&quot;&gt;Lots to fit on at low zoom if everything is turned on&lt;/td&gt;&lt;/tr&gt;&lt;/tbody&gt;&lt;/table&gt;&lt;table cellpadding=&quot;0&quot; cellspacing=&quot;0&quot; class=&quot;tr-caption-container&quot; style=&quot;float: right; margin-left: 1em; text-align: right;&quot;&gt;&lt;tbody&gt;&lt;tr&gt;&lt;td style=&quot;text-align: center;&quot;&gt;&lt;a href=&quot;https://3.bp.blogspot.com/-1_kQ3izeq-E/WCpBylk9ffI/AAAAAAAAChc/9q0bG-ZPWcMQ7UHi9QgLeFAt_nGkqSx3wCLcB/s1600/foodstalls.png&quot; imageanchor=&quot;1&quot; style=&quot;clear: right; margin-bottom: 1em; margin-left: auto; margin-right: auto;&quot;&gt;&lt;img border=&quot;0&quot; height=&quot;320&quot; src=&quot;https://3.bp.blogspot.com/-1_kQ3izeq-E/WCpBylk9ffI/AAAAAAAAChc/9q0bG-ZPWcMQ7UHi9QgLeFAt_nGkqSx3wCLcB/s320/foodstalls.png&quot; width=&quot;199&quot; /&gt;&lt;/a&gt;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td class=&quot;tr-caption&quot; style=&quot;text-align: center;&quot;&gt;Food stalls need room for their much longer real names &lt;/td&gt;&lt;/tr&gt;&lt;/tbody&gt;&lt;/table&gt;By the time we get to the highest zoom level (22) there&#39;s lots of space in most places. I needed that zoom level to comfortably resolve the food stalls, which are 3m x 3m, with an icon and room for their name. I needed to display a lot of food supplier names close together and the names needed to respond to a touch (or click). I used the Leaflet plugin Leaflet.Label for this. If I had used Leaflet 1.0, rather than 0.7, I think I could have used built-in tool tips instead.&lt;br /&gt;&lt;br /&gt;There is an optical illusion when you zoom in on an icon, especially on a phone where you use pinch zoom. If you show the higher zoom level with the same size icon on it the icon seems to have shrunk. People expect pinch zoom to make things bigger, so I increase the size of the icons as each level zooms in. That is easy for the stuff on the base map, Tilemill makes that simple, but scaling the icons on overlays took a bit of code I&#39;d not needed to use before. This involves resizing the icon and using setIcon() to use the newly sized icon in a marker. setIcon() is not documented in Leaflet 0.7, but works just the same.&lt;br /&gt;&lt;br /&gt;The standard Leaflet layer control is much too small for a mobile phone. I tweaked the size and position with CSS. I also discovered that you don&#39;t need a base layer on the control and you can force it to always be open. Both are perfectly plainly described in the really good documentation of Leaflet, I&#39;d just not read that bit before. &lt;br /&gt;&lt;br /&gt;I control the markers on the map by describing them in geoJson files, one for each overlay. To position the many markers on the map I created a simple editor which uses the Leaflet.Draw plugin, which is really simple to use in code and produces a very useful editor.&lt;br /&gt;&lt;br /&gt;I have enjoyed creating this map and working with creative people who have an absolute deadline to work to. If you are in Hong Kong on 25 - 27th November enjoy Clockenflap and enjoy using my map to find all the stuff Clockenflap has to offer. </description><link>http://chris-osm.blogspot.com/2016/11/a-map-in-app.html</link><author>noreply@blogger.com (Unknown)</author><media:thumbnail xmlns:media="http://search.yahoo.com/mrss/" url="https://2.bp.blogspot.com/-Wmv7Vb1IYsU/WCo_zEFb46I/AAAAAAAAChQ/430qu4-sRo0YoDkVO4fp1dCautm03PyjQCLcB/s72-c/jumble.png" height="72" width="72"/><thr:total>1</thr:total></item><item><guid isPermaLink="false">tag:blogger.com,1999:blog-179325926611299376.post-5535131837123107308</guid><pubDate>Fri, 05 Feb 2016 16:30:00 +0000</pubDate><atom:updated>2016-02-05T16:30:38.786+00:00</atom:updated><title>Drains and meadows</title><description>I mapper jumped into mapping the rural areas of East Yorkshire more than a year ago but, sadly, seems to have stopped. This mapper has added farmland and woods in much more detail than anything before and has drawn the outlines of lots of buildings in villages too. There are a couple of things that I&#39;ve decided to change in any areas that I take a look at now. That is meadows and drains.&lt;br /&gt;&lt;br /&gt;Meadows are a special thing in Britain, with most having disappeared. They are not just areas of grassland but a very specific kind of management, involving no fertiliser, a careful cutting of the grass for hay more than once a year and some animal grazing, but not all year round. The timing of the hay cuts allows wild flowers to flourish as they have time to set seed before they are cut down. This makes a beautiful landscape that has all but vanished from the English countryside. The mapper has made the mistake that almost any green field in the aerial imagery is a meadow, so I&#39;m checking as best I can on the ground and changing it to farmland unless it really is a meadow. The farmland is drawn with each field outlined which means I can try to add hedges when I see them. This too improves the quality of the rural mapping.&lt;br /&gt;&lt;br /&gt;The other problem is that every field-side ditch has been mapped as a drain. This is further worsened by another mapper doing the same thing in Holderness, the flat land to the east of Hull. There are some waterways I would call a drain there, but most are ditches in my view. A ride out doesn&#39;t cover much ground to correct this and imagery is ambiguous at best. So there&#39;s lots to check and much will change.&lt;br /&gt;&lt;br /&gt;The East Riding countryside is a great place to spend time; having an excuse to carefully explore and examine more of it in detail is no bad thing, so I&#39;m not complaining.</description><link>http://chris-osm.blogspot.com/2016/02/drains-and-meadows.html</link><author>noreply@blogger.com (Unknown)</author><thr:total>0</thr:total></item><item><guid isPermaLink="false">tag:blogger.com,1999:blog-179325926611299376.post-5291690938405807165</guid><pubDate>Tue, 02 Feb 2016 12:08:00 +0000</pubDate><atom:updated>2016-02-02T13:23:31.040+00:00</atom:updated><title>Schools</title><description>People meet up in a few areas across Britain drawn together to share views and ideas about OSM. One of these is known as Mappa Mercia, meeting in the old Kingdom of Mercia, roughly the Midlands. They started a quarterly series of projects which encourages people to focus on improving specific areas, such as nature reserves. This quarter it is schools.&lt;br /&gt;&lt;br /&gt;People across Britain have taken to the suggestion of checking schools and improving the quality of recording schools. This is a simple idea that will greatly improve the quality of data in OSM, something that the quarterly projects have always aimed at. It&#39;s a great idea and something I support.&lt;br /&gt;&lt;br /&gt;There is a list of UK schools available as open data which Robert has used to show a map of how well the schools in the list are represented in OSM. It uses postcode areas as that is how the open data is structured. This is a very good indicator of areas that still need work.&lt;br /&gt;&lt;br /&gt;This is all useful, but then I think the project took a wrong turn. People were encouraged to add a hashtag to changeset comments. This has then been used to produce a list of people who have contributed the most changes to the project. I don&#39;t like this. OSM is not a competition and turning it into one encourages edits just to climb the list (I&#39;m not accusing anyone of that, just that the pressure is created). We have seen that with the list of anomalies published between OS Locator road names and OSM road names. To push an area up the list people just use the OS Locator names without checking. I know that OS Locator contains errors and there is a mechanism to record these, but many areas have very few recorded errors, so erroneous OS data is now in OSM.&lt;br /&gt;&lt;br /&gt;I like the idea of focussing on improving specific things in OSM. It should encourage surveying. I would prefer it is not be seen as a competition.</description><link>http://chris-osm.blogspot.com/2016/02/schools.html</link><author>noreply@blogger.com (Unknown)</author><thr:total>2</thr:total></item><item><guid isPermaLink="false">tag:blogger.com,1999:blog-179325926611299376.post-3467663473585363469</guid><pubDate>Fri, 27 Nov 2015 16:43:00 +0000</pubDate><atom:updated>2015-12-01T17:38:55.837+00:00</atom:updated><title>When is a town not a town?</title><description>I live a few miles away from a rapidly growing settlement called &lt;a href=&quot;http://www.openstreetmap.org/#map=14/53.7333/-0.5720&quot;&gt;Brough&lt;/a&gt;. I see it mentioned from time to time as a town in the local press, but I&#39;ve always thought of it as a large village. It has been a settlement for a long time, it was a town, Peturia, when Rome ruled this area.&lt;br /&gt;&lt;br /&gt;The idea of not knowing whether a place in England is a town or a village seems easy to resolve: does it have a town council or a parish council? Well in the case of Brough it is not quite so easy. The local council is a town council, but it covers both Elloughton and Brough and is called Elloughton-cum-Brough Town Council. It is not that uncommon to find a civil parish or town council with multiple settlements within its bounds, but the council is a town council, surely one of the settlements needs to be a town.&lt;br /&gt;&lt;br /&gt;&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;&lt;a href=&quot;http://1.bp.blogspot.com/-xlJaJbhV8zc/VliIHMH1IpI/AAAAAAAAB8o/A8kf_Bo-AEc/s1600/ell-cum-brough.JPG&quot; imageanchor=&quot;1&quot; style=&quot;clear: right; float: right; margin-bottom: 1em; margin-left: 1em;&quot;&gt;&lt;img border=&quot;0&quot; height=&quot;318&quot; src=&quot;http://1.bp.blogspot.com/-xlJaJbhV8zc/VliIHMH1IpI/AAAAAAAAB8o/A8kf_Bo-AEc/s320/ell-cum-brough.JPG&quot; width=&quot;320&quot; /&gt;&lt;/a&gt;&lt;/div&gt;It is clear to me there are two settlements here. Road signs show both places sometimes in different directions, OS Locator shows the street names as streetname : Brough : Elloughton-cum-Brough and streetname : Elloughton : Elloughton-cum-Brough.&lt;br /&gt;&lt;br /&gt;OS Open Names shows both places as populatedPlace: village. So is it possible to have a town council presiding over an area with two villages and no towns in it?&lt;br /&gt;&lt;br /&gt;I&#39;ve asked the Local Authority, who, after all, provide the data for OS Locator and OS Open Names, what they think.&lt;br /&gt;&lt;br /&gt;The answer is a political hot potato at the moment, as Elloughton-cum-Brough town council have recently decided to spend £4000 on a mayoral-style chain for the head of the council. It seems he can legitimately call himself mayor after the town council made the appropriate change in 2011. That&#39;s a lot of money to spend on what some call trinkets at a time when there are council cuts elsewhere.&lt;br /&gt;&lt;br /&gt;Edit:&lt;br /&gt;The clerk to the Elloughton-cum-Brough has contacted me and kindly given me information about the process that resulted in the parish council becoming a town council. She also confirmed that both Brough and Elloughton are villages. That means that the town council area has two villages and no towns in it.&lt;br /&gt;&lt;br /&gt;</description><link>http://chris-osm.blogspot.com/2015/11/when-is-town-not-town.html</link><author>noreply@blogger.com (Unknown)</author><media:thumbnail xmlns:media="http://search.yahoo.com/mrss/" url="http://1.bp.blogspot.com/-xlJaJbhV8zc/VliIHMH1IpI/AAAAAAAAB8o/A8kf_Bo-AEc/s72-c/ell-cum-brough.JPG" height="72" width="72"/><thr:total>3</thr:total></item><item><guid isPermaLink="false">tag:blogger.com,1999:blog-179325926611299376.post-1101028669053509699</guid><pubDate>Mon, 28 Sep 2015 13:36:00 +0000</pubDate><atom:updated>2015-09-28T14:36:59.856+01:00</atom:updated><title>Extracting building heights from LIDAR</title><description>The UK Environment Agency have released some LIDAR data in Digital Elevation Model (DEM) format. It includes Digital Terrain Model (DTM) data and Digital Surface Model data. The DSM data includes buildings and trees while the DTM is processed to remove these so the underlying terrain is visible. Tim Waters asked if you subtract the DTM from the DSM would you be left with just building and tree heights? I&#39;d started to look at this and it turns out building heights are extractable in this way.&lt;br /&gt;&lt;br /&gt;I have written a script to do the subtraction and create both the difference file and an SQL file to load the data into a postgresql table. I created a hill shading image from one of the difference files to see what features have been stripped from the DTM data. Here&#39;s a jpg version of it:&lt;br /&gt;&lt;br /&gt;&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;&lt;a href=&quot;http://2.bp.blogspot.com/-A8irnPsuREM/Vgk2NZO443I/AAAAAAAAB5k/fu5mrBI8HKc/s1600/sub.jpg&quot; imageanchor=&quot;1&quot; style=&quot;margin-left: 1em; margin-right: 1em;&quot;&gt;&lt;img border=&quot;0&quot; height=&quot;400&quot; src=&quot;http://2.bp.blogspot.com/-A8irnPsuREM/Vgk2NZO443I/AAAAAAAAB5k/fu5mrBI8HKc/s400/sub.jpg&quot; width=&quot;400&quot; /&gt;&lt;/a&gt;&lt;/div&gt;&lt;br /&gt;You can see that the buildings and some other features are all well defined. Phil Endecott suggested using the DSM data to create building outlines which could be traced in OSM. His images look good. I would suggest starting his process with this difference data as all the terrain detail has been removed so it may be even better.&lt;br /&gt;&lt;br /&gt;Once the SQL file of height data has been loaded into a Postgresql database, which has the PostGIS extension installed, we can then do some queries on it. I selected some OSM building polygons in the range of the loaded data and found which of the height points fell within each polygon. The highest of these is the highest point of the building above the surrounding terrain. I&#39;ve written a script as a place-holder to extract all the heights for a rectangular area. Someone could extend this to make a file to upload to OSM to add the heights for every building in the defined area. I feel this is clearly an import and so the usual &lt;a href=&quot;http://wiki.openstreetmap.org/wiki/Automated_Edits_code_of_conduct&quot;&gt;OSM import process&lt;/a&gt; needs to be gone through before the import takes place.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;I think there is real merit in using this data to extract building heights, which are needed for the 3D images of city buildings.&lt;br /&gt;&lt;br /&gt;The two scripts are available here: &lt;a href=&quot;http://www.raggedred.net/shared/heights.zip&quot;&gt;http://www.raggedred.net/shared/heights.zip&lt;/a&gt; The first (s-t.py) needs matching DSM and DTM files and outputs a difference file and the SQL to load into a database table. This will work for any of the resolutions published by the EA. The second, much less polished, script (match.py) defines a rectangle, extracts the OSM buildings for that rectangle and then finds the height data for each building. I wrote it as a script so it can be extended to create a data file for processing or uploading or so overlay tiles could be made from it. I loaded some OSM data with osm2pgsql (which would normally be used for rendering) and added the table for the heights data to the database. The SQL for the table is:&lt;br /&gt;&lt;blockquote class=&quot;tr_bq&quot;&gt;&lt;span style=&quot;font-family: &amp;quot;Courier New&amp;quot;,Courier,monospace;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;span style=&quot;font-family: &amp;quot;Courier New&amp;quot;,Courier,monospace;&quot;&gt;CREATE TABLE eadata&lt;br /&gt;(&lt;br /&gt;&amp;nbsp; hid serial NOT NULL,&lt;br /&gt;&amp;nbsp; height double precision,&lt;br /&gt;&amp;nbsp; locn geometry(Point,27700),&lt;br /&gt;&amp;nbsp; CONSTRAINT eaheight_prim PRIMARY KEY (hid)&lt;br /&gt;)&lt;br /&gt;WITH (&lt;br /&gt;&amp;nbsp; OIDS=FALSE&lt;br /&gt;);&lt;br /&gt;&lt;br /&gt;CREATE INDEX eadata_index&lt;br /&gt;&amp;nbsp; ON eadata&lt;br /&gt;&amp;nbsp; USING gist&lt;br /&gt;&amp;nbsp; (locn);&lt;/span&gt;&lt;/blockquote&gt;The output SQL data can be loaded into this with the command:&lt;br /&gt;&lt;blockquote class=&quot;tr_bq&quot;&gt;psql &lt;dbname&gt; -f &lt;filename&gt;&lt;/filename&gt;&lt;/dbname&gt;&lt;/blockquote&gt;where &lt;dbname&gt; and &lt;filename&gt; are whatever you used. The table name eadata and field names are hard-coded in s-t.py.&amp;nbsp;&lt;/filename&gt;&lt;/dbname&gt;&lt;br /&gt;&lt;br /&gt;It is important to say that I would not use a rendering database to create the upload data from as some fields will be missing. osm2pgsql is a lossy process. You can use the OSM ID to extract a current version from the API or from Overpass to add the height data to. I used the rendering data for convenience as I already had it available and to satisfy myself that the process works. &amp;nbsp; &lt;br /&gt;&lt;br /&gt;I hope this is useful to someone. Please feel free to ask for more information if I&#39;ve not made anything clear.</description><link>http://chris-osm.blogspot.com/2015/09/extracting-building-heights-from-lidar.html</link><author>noreply@blogger.com (Unknown)</author><media:thumbnail xmlns:media="http://search.yahoo.com/mrss/" url="http://2.bp.blogspot.com/-A8irnPsuREM/Vgk2NZO443I/AAAAAAAAB5k/fu5mrBI8HKc/s72-c/sub.jpg" height="72" width="72"/><thr:total>6</thr:total></item><item><guid isPermaLink="false">tag:blogger.com,1999:blog-179325926611299376.post-4364259102000178425</guid><pubDate>Sun, 20 Sep 2015 17:31:00 +0000</pubDate><atom:updated>2017-03-14T21:22:12.480+00:00</atom:updated><title>More LIDAR goodness</title><description>I looked into LIDAR data from the &lt;a href=&quot;https://www.gov.uk/government/organisations/environment-agency&quot;&gt;UK Environment Agency&lt;/a&gt; some weeks ago. I needed it help a local group who are investigating flood mitigation options. The data was listed as being about £26,500 but we got a 100% discount if we used it for restricted, research use, so we could afford it! A few weeks after I&#39;d used the height data for the group I got an email from the Environment Agency. They said the data was being made available as Open Data under the &lt;a href=&quot;http://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/&quot;&gt;Open Government Licence&lt;/a&gt;. So now I could use it for any other purposes at no cost. You can get the data from &lt;a href=&quot;http://environment.data.gov.uk/ds/survey&quot;&gt;http://environment.data.gov.uk/ds/survey&lt;/a&gt;&lt;br /&gt;&lt;br /&gt;I decided to make a detailed relief map of part of the area close to home. The data doesn&#39;t cover the whole country, only parts that are deemed at risk of flooding. All of Hull and the river Hull catchment area are included in this. I&#39;ve only looked at my local area so other areas may vary.&lt;br /&gt;&lt;br /&gt;The data is downloaded as Ordnance Survey 10km grid tiles. There are 2m, 1m, 50cm and 25cm options and digital terrain model and digital surface model options too, so let&#39;s look at these options, but first a bit about LIDAR.&lt;br /&gt;&lt;br /&gt;&lt;a href=&quot;https://en.wikipedia.org/wiki/Lidar&quot;&gt;LIDAR&lt;/a&gt; is a technology that uses laser light to measure a distance repeatedly over an area to create a 3D model of an area. If the LIDAR transceiver is mounted at a fixed point it can pan around to record a very detailed image in 3D of everything that can be seen from that point. It works very well in this way inside a building or a cave to make a very accurate model. The US Space Shuttle flew a mission to use a variant of LIDAR to record the height of the surface of the Earth from space. This is available as &lt;a href=&quot;http://www2.jpl.nasa.gov/srtm/&quot;&gt;SRTM&lt;/a&gt;.&lt;br /&gt;&lt;br /&gt;More recently LIDAR equipment has been flown in aircraft. The difficulty of making useful measurements from an aircraft should not be underestimated. The only data LIDAR returns is distance to the target, so knowing PRECISELY where the aircraft is in 3D is the real problem. GPS is hopeless at altitude measurement and scarcely good enough for lateral location, barometric height measurements vary over time and location and inertial dead-reckoning accuracy falls off with time. A combination of all of these plus post-processing can result in useful data.&lt;br /&gt;&lt;br /&gt;The Environment Agency LIDAR distance options specify the distance between the sample points, the 2m option having less detail than the 25cm option. The area that these options cover varies with the highest detail covering the smallest area. I chose the 50cm option as it covered the area I wanted at the highest level of detail. The detail does make for larger datasets and more processing needed to do anything with it.&lt;br /&gt;&lt;br /&gt;Clearly the LIDAR measures the distance to the first object it encounters from the aircraft, so it measures tree tops, building roofs and even vehicles. This is known as the digital surface model. This is often a composite from multiple images, as this data is, to compensate for location inaccuracies and to help remove things like vehicles. To get a useful model of the real landscape, without trees and buildings, the data is post processed to create the digital terrain model. This is the data I have used.&lt;br /&gt;&lt;br /&gt;The OGL data was different from the data the Environment Agency originally supplied. The original data was in smaller grid squares and the height was rounded to the nearest centimetre. The OGL data is in bigger squares which makes it a bit easier to process but seems to use 18 decimal places of a metre, which is smaller than the diameter of an atom.&lt;br /&gt;&lt;br /&gt;I wanted to create a relief map and make contours from the data and, not for the first time, &lt;a href=&quot;http://www.gdal.org/&quot;&gt;GDAL&lt;/a&gt; had the tools. The data uses the UK Ordnance Survey projection, known as OSGB36 or ESPG:27700, so to use any OSM data with it I would need to reproject to WGS84 or EPSG:4326.&lt;br /&gt;&lt;br /&gt;To make a relief map I used gdaldem with the hillshade option on each of the datafiles. These need to be joined together to make a larger image, so the option -compute-edges is also needed. The complete command is:&lt;br /&gt;&lt;blockquote class=&quot;tr_bq&quot;&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;gdaldem hillshade -compute_edges infile relieftiff/outfile.tif&lt;/span&gt;&lt;/blockquote&gt;The output is geoTIFF files which can be merged into a single (large) geoTIFF with the command&lt;br /&gt;&lt;blockquote class=&quot;tr_bq&quot;&gt;gdal_merge.py -o big.tif *.tif&lt;/blockquote&gt;This creates a geoTIFF file which has the image of the relief in a TIFF image and also has the locations of the edges in the original OS projection.&lt;br /&gt;&lt;br /&gt;The next step is to use gdalwarp to reproject the large tiff file to one in the WGS84 projection. The command describes the source and target projection and filenames. There are significant missing pieces in the large TIFF as the available data was not rectangular. The -srcnodata 0 and -dstalpha makes missing data transparent rather than black.&lt;br /&gt;&lt;blockquote class=&quot;tr_bq&quot;&gt;gdalwarp -s_srs epsg:27700 -t_srs epsg:4326 -srcnodata 0 -dstalpha big.tif bigr.tif&lt;/blockquote&gt;The new TIFF file is what we want to see, but now it needs turning into tiles to be displayed on a slippy map. I decided that zoom level 13 to 18 would give a useful display. To make these tiles I used gdal2tiles.py, specifying the reprojected TIFF image, the zoom levels and the folder to put the tiles into.&lt;br /&gt;&lt;blockquote class=&quot;tr_bq&quot;&gt;gdal2tiles.py -z13-19 bigrt.tif tiles&lt;/blockquote&gt;This makes a set of tiles in the TMS format in the specified folder, in this case tiles.&lt;br /&gt;&lt;br /&gt;Another way to visualise the LIDAR data is contours. I decided to create a set of overlay tiles that are transparent except for the contours. These can have a different density of contours at each zoom level. I chose the smallest contour step to be shown at the highest zoom level to be 0.2 metres. The GDAL tool for the job is gdal_contour which makes a shapefile with a linestring for each contour. The command is&lt;br /&gt;&lt;blockquote class=&quot;tr_bq&quot;&gt;gdal_contour -i 0.2 -a height infile outshapefile.shp&lt;/blockquote&gt;The resulting shapefile needs to be reprojected to WGS84. The tool to reproject shapefiles is ogr2ogr&lt;br /&gt;&lt;blockquote class=&quot;tr_bq&quot;&gt;ogr2ogr -t_srs epsg:4326 -s_srs epsg:27700 outshape.shp new.shp&lt;/blockquote&gt;I decided to use Mapnik to make the contour overlay tiles. Mapnik can use shapefiles but specifying the long list of shapefiles created above would be a problem so I loaded the shapefiles into a postgresql table in a database with PostGIS enabled. Postgresql comes with shp2pgsql to do this:&lt;br /&gt;&lt;blockquote class=&quot;tr_bq&quot;&gt;shp2pgsql -a -g way new.shp eacontours &amp;gt; new.sql&lt;/blockquote&gt;This makes SQL to load the shapefile into eacontours table, putting the geometry in the field called way. To load this into a database called ukcontours which already has the postgis extension installed the command is&lt;br /&gt;&lt;blockquote class=&quot;tr_bq&quot;&gt;psql -d ukcontours -f new.sql&lt;/blockquote&gt;I then designed the overlay with Tilemill to create the transparent tiles with more contours at higher zoom levels.&lt;br /&gt;&lt;br /&gt;You can see the results at &lt;a href=&quot;http://relief.raggedred.net/&quot;&gt;http://relief.raggedred.net&lt;/a&gt;. I added a water overlay and a roads overlay (thanks to MapQuest for the roads) to help position the relief imagery.</description><link>http://chris-osm.blogspot.com/2015/09/more-lidar-goodness.html</link><author>noreply@blogger.com (Unknown)</author><thr:total>2</thr:total></item><item><guid isPermaLink="false">tag:blogger.com,1999:blog-179325926611299376.post-2585971643263278746</guid><pubDate>Tue, 11 Aug 2015 17:14:00 +0000</pubDate><atom:updated>2015-11-17T22:21:07.099+00:00</atom:updated><title>Strapped</title><description>Hull is a low-lying city, as are some of the towns and villages that surround it. I have blogged before about the serious flooding in the area in 2007, just before I started mapping in OSM. What a lot of people won&#39;t know, even locals, is that flooding is a regular occurrence in some parts of the area. This flooding is on a much smaller scale than happened in 2007, but it still causes misery for anyone whose house is flooded. The Cottingham Flood Action Group have tried to understand what causes this regular flooding and then campaign to fix the causes. I have helped a bit by providing maps and overlaying data from various sources. Some of these sources are not open so I don&#39;t want to publish them here.&lt;br /&gt;&lt;br /&gt;One source of contention is riparian ownership. This can apply when a water course runs through your land and you may then be required to maintain it. For example a ditch carrying surface water away may need to be cleaned out so water can actually flow in the ditch and not back up causing a flood elsewhere.&lt;br /&gt;&lt;br /&gt;The East Riding of Yorkshire council is strapped for cash. They are pushing people to maintain ditches and in some cases ditches in culverts to prevent flooding, claiming these people are riparian owners of the ditches. To be a riparian owner the watercourse must be wholly within the property or form the boundary of the property. If the watercourse forms a boundary, then the property owner owns the watercourse to the mid line.&lt;br /&gt;&lt;br /&gt;I have matched the Land Registry Inspire dataset to my surveys of a few of these and it clearly shows that the ditch is many metres outside of the privately owned land and well within the area of the public highway. This means that no matter how strapped the council is for cash, they must maintain the ditch or culvert. Of course, my survey probably isn&#39;t enough to convince the council, but it certainly should prompt people to get more evidence.&lt;br /&gt;&lt;br /&gt;Don&#39;t believe your council. If they claim you are responsible for something unusual, make them prove it and make sure you get enough facts to stand up to them. The council may be right, but they be just trying to get you to pay for something they are responsible for. </description><link>http://chris-osm.blogspot.com/2015/08/strapped.html</link><author>noreply@blogger.com (Unknown)</author><thr:total>0</thr:total></item><item><guid isPermaLink="false">tag:blogger.com,1999:blog-179325926611299376.post-5614757858870541163</guid><pubDate>Thu, 25 Jun 2015 16:52:00 +0000</pubDate><atom:updated>2015-06-25T17:52:38.851+01:00</atom:updated><title>Lidar</title><description>Today I received two DVDs with Lidar data on them.

When there was nothing on the map I just added what I found but now there is a fairly complete road network. Keeping that up to date can be hard work - how do you know what has been added since the last time I looked? OS Locator is really valuable for this as new roads appear on there as OS maps them. It would be better to know developments are starting and get in early and I think there may be a way: postcodes.&lt;br /&gt;&lt;br /&gt;New postcodes are allocated all the time. Around a thousand are created every month in GB. The Office of National Statistics publish a postcode list based on Codepoint Open data but with some extra stuff in there. One thing is the month the postcode was set up. Looking at the recent ones may let us find places that need surveying.&lt;br /&gt;&lt;br /&gt;I&#39;ve created a map to visualise these: &lt;a href=&quot;http://pcage.raggedred.net/&quot;&gt;http://pcage.raggedred.net&lt;/a&gt; &lt;br /&gt;&lt;br /&gt;I hope this proves useful.</description><link>http://chris-osm.blogspot.com/2015/06/when-does-postcode-start.html</link><author>noreply@blogger.com (Unknown)</author><thr:total>2</thr:total></item><item><guid isPermaLink="false">tag:blogger.com,1999:blog-179325926611299376.post-4393561707405936524</guid><pubDate>Wed, 03 Jun 2015 19:39:00 +0000</pubDate><atom:updated>2015-06-03T20:44:06.361+01:00</atom:updated><title>New postcode layer</title><description>I&#39;ve just finished extracting the data from a full download of OS Open Names and setting up a layer to see the new postcodes. The postcode data is only a centroid for each postcode area. &lt;br /&gt;&lt;br /&gt;I maintain a layer of postcodes from the Office of National Statistics, one from Codepoint Open and now Open Names. The Codepoint Open and ONS postcodes are in the same locations, though Codepoint Open data is a bit more up-to-date right now. The OS Open Names postcode locations are now sub-metre, so I expected that the centroid might be in a slightly different location, but some are substantially different as you can see here.&lt;br /&gt;&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;&lt;a href=&quot;http://2.bp.blogspot.com/-Qm2kVEPyiCI/VW9Uw803IPI/AAAAAAAAB30/HB90N1eRZUU/s1600/postcodes.png&quot; imageanchor=&quot;1&quot; style=&quot;margin-left: 1em; margin-right: 1em;&quot;&gt;&lt;img border=&quot;0&quot; src=&quot;http://2.bp.blogspot.com/-Qm2kVEPyiCI/VW9Uw803IPI/AAAAAAAAB30/HB90N1eRZUU/s1600/postcodes.png&quot; /&gt;&lt;/a&gt;&lt;/div&gt;&amp;nbsp;The Codepoint Open are in red, the OS Open Names are in magenta.&lt;br /&gt;&lt;br /&gt;I don&#39;t store any of these tiles, I render them on the fly. Real tiles are often stored in a hierarchy of folders in the form of&lt;br /&gt;&lt;blockquote class=&quot;tr_bq&quot;&gt;&lt;span style=&quot;font-family: &amp;quot;Courier New&amp;quot;,Courier,monospace;&quot;&gt;tilename-base/zoom/xposition/yposition.png&lt;/span&gt;&lt;/blockquote&gt;Since I don&#39;t store any of these, when someone requests a tile they would normally get a &quot;Not found (404)&quot; error. I trap these errors and use the folder hierarchy to extract the postcode centroids from a database for the zoom, x and y area of the tile.&amp;nbsp; This is used to render a tile with a transparent background and centroid markers on it. I do this because I didn&#39;t want to use the considerable disk space the real tiles would take up, especially as I create to to zoom level 21 to make editing easier with the layer switched on.&lt;br /&gt;&lt;br /&gt;I also extracted the road name and place name data, reprojected all of the location data from OS grid references to lon and lat and stored them for later use. If anyone wants to see this I&#39;ll happily pass it on, just ask.&lt;br /&gt;&lt;br /&gt;If you want to see the new postcodes you can see the new layer on &lt;a href=&quot;http://oscompare.raggedred.net/?zoom=13&amp;amp;lat=53.74575&amp;amp;lon=-0.48529&amp;amp;layers=0B0FFTFT&quot;&gt;oscompare&lt;/a&gt;. Make sure you open the layer selection (blue+white +) and select what you want to see.  You need to zoom in to see the postcodes.</description><link>http://chris-osm.blogspot.com/2015/06/new-postcode-layer.html</link><author>noreply@blogger.com (Unknown)</author><media:thumbnail xmlns:media="http://search.yahoo.com/mrss/" url="http://2.bp.blogspot.com/-Qm2kVEPyiCI/VW9Uw803IPI/AAAAAAAAB30/HB90N1eRZUU/s72-c/postcodes.png" height="72" width="72"/><thr:total>6</thr:total></item><item><guid isPermaLink="false">tag:blogger.com,1999:blog-179325926611299376.post-3999719127448457403</guid><pubDate>Tue, 02 Jun 2015 16:49:00 +0000</pubDate><atom:updated>2015-06-02T17:49:38.194+01:00</atom:updated><title>Twenty by twenty</title><description>It seems that there are not missing sections in the OS Open Names downloads from OS OpenData.

The file is a strange mixture of three types of data jumbled up. So I needed to separate them into something useful. The three types are postcode centroids, place names and road names. All of the locations are in the projection that Ordnance Survey use, OSGB36 or EPSG:27700. The great thing about the values used in this projection is that they are measured in metres from a fixed point. The previous OS open data, such as OS Locator or CodePoint Open (postcode centroids) use this projection too of course which fixes a location to a square metre. OS Open Names however has a decimal component so the location is now specified to the nearest millimetre - more accurate than OSM works to. The east-west specification in OS parlance is know as eastings and the north-south specification is known as northings. Eastings and northings can be converted to longitude and latitude for use in OSM using, for example, GDAL libraries.&lt;br /&gt;&lt;br /&gt;The postcode centroids are very simple records. It needs the postcode and the easting and northing for the location of the centroid. Comparing a few OS Open Names centroids with Codepoint Open records the centroids are in slightly different locations. &lt;br /&gt;&lt;br /&gt;OS Locator lists named roads with its name, a centroid and a bounding box for the road. There is also a hierarchy of place, borough, county or unitary authority.&amp;nbsp; All of this is in OS Open Names and the increased millimetre accuracy is there too.&lt;br /&gt;&lt;br /&gt;I&#39;ve not used the gazetteer of place names, but the name and location data are available as you would expect.&lt;br /&gt;&lt;br /&gt;All of the data types have some URIs in the files too for many of the fields. Many that I have tried to open are dead links, but some show the hierarchy of data. I&#39;m not sure why this is useful. &lt;br /&gt;&lt;br /&gt;I think I&#39;m going to write a routine to unzip and process all of the OS Open Names data. I&#39;ll load the data into a database, reproject it for OSM and make the processed data available if anyone wants it.&lt;br /&gt;&lt;br /&gt;First, however, OS need to supply the missing sections of their open data. </description><link>http://chris-osm.blogspot.com/2015/06/os-open-names.html</link><author>noreply@blogger.com (Unknown)</author><thr:total>2</thr:total></item><item><guid isPermaLink="false">tag:blogger.com,1999:blog-179325926611299376.post-924592286371842681</guid><pubDate>Mon, 01 Jun 2015 16:12:00 +0000</pubDate><atom:updated>2015-06-02T16:54:21.208+01:00</atom:updated><title>OS Locator is to be withdrawn</title><description>I just received an email from Ordnance Survey, telling me that OS Locator, part of the OS Open Data, is to be withdrawn in a year&#39;s time. They say that OS Open Names has been published and that replaces OS Locator. They hint that it may replace CodePoint Open too, though there&#39;s no notice of withdrawal for that yet. I thought I should look at OS Open Names to see what it offers. &lt;br /&gt;&lt;br /&gt;The first thing I saw was that the data is broken into the OS large-scale grid squares, which break the country into a 13x7 grid with 55 squares with actual data in them. Each one of these needs to be downloaded separately to cover GB. That is a pain to start with. I requested SE and TA which are both needed to cover the village I live in. After downloading them the .zip file contains each area broken down into 100 separate sections as I would expect, but I quickly realised that there were only 25 in SE and 10 in TA. Much of TA covers the North Sea, so there should be fewer sections, but clearly many were still missing. I downloaded another area and again the same 75 sections were missing. I emailed customer service at OS to point this out, with no answer yet.&lt;br /&gt;&lt;br /&gt;I pressed on to look at the data in the sections that were there. The data is in a CSV format (there was another choice). There is a summary of column headings, but the data is a strange muddle of three types of data. Much of the data is a url to an OS website with the data summarised on a page for each column of each line of the text. It appears that there is a record type for place names, a record type for postcode centroids and a record type for named roads all freely mixed up throughout the file. There doesn&#39;t seem to be a field to simply identify what the record type is for each line. The first field is an id field. For place names it seems to start with osgb and has a number after that, for postcodes a postcode type id, with spaces removed, is in the id field and for road names an id that looks like a GUID is in the field. It doesn&#39;t seem to be a pattern for why the data is in the order that it is.&lt;br /&gt;&lt;br /&gt;I&#39;m going to throw some code together to disentangle these record types and see what useful data is then available. Hopefully we will not have lost anything useful in this process, though it does look as though processing this open data is going to be a bit harder than it used to be.&lt;br /&gt;&lt;br /&gt;Anyone would think OS don&#39;t want to release open data.&lt;br /&gt;&lt;br /&gt;Edit: There are two fields which distinguishes these different record types. </description><link>http://chris-osm.blogspot.com/2015/06/os-locator-is-to-be-withdrawn.html</link><author>noreply@blogger.com (Unknown)</author><thr:total>0</thr:total></item><item><guid isPermaLink="false">tag:blogger.com,1999:blog-179325926611299376.post-4490374717448722334</guid><pubDate>Mon, 01 Jun 2015 11:38:00 +0000</pubDate><atom:updated>2015-06-01T12:38:56.910+01:00</atom:updated><title>Road Closure</title><description>The road I live on is closed. A house needs some work done on it. The house wall is tight against the road and that part of the road is also narrow. Scaffolding to work on the house now stands to the middle of the road, so the road is closed to vehicles for two weeks&lt;br /&gt;&lt;br /&gt;Should I change the road in Openstreetmap to reflect this temporary closure? I have decided not to change it. Anyone trying to use the road in a vehicle will be directed by another route, by the signs. Most are locals so they will know the alternatives anyway. If I make a change to OSM and someone downloads a snapshot of the data with that change in place they may not download a new version for a while and have the break in the road long after it has actually reopened. Anyway the road exists - it&#39;s just not accessible to vehicles for a while.&lt;br /&gt;&lt;br /&gt;This closure has caused some very poor driving standards to surface. The alternative routes are small residential roads with parked cars and tight and narrow corners. People using these routes seem to need to take out some annoyance with their normal route being closed by roaring through these streets at ludicrous speeds with no intention to give way to anyone else.&lt;br /&gt;&lt;br /&gt;The closure was a surprise to me. I saw a sign go up announcing the closure a couple of days before it happened. When I tried to find out why the road was being closed I drew a blank. The council didn&#39;t respond to my request for information and searching their website produced nothing at all. A neighbour pointed out that there was a notice in the local newspaper which was reproduced online. Few few people still read the Hull Daily Mail - it has been steadily descending way below mediocrity for many years.&amp;nbsp; The online notice didn&#39;t appear in my searches because it is not sensibly indexed. The HDM website is a nightmare to use, with any page constantly bouncing around as adverts and videos randomly pop up and freeze the pages.&lt;br /&gt;&lt;br /&gt;Councils are obliged to publish public notices about some things, such as road closures. It&#39;s clear to me that publishing in the local newspaper is not a viable way to do this as they no longer reach much of the population. A sensible addition would be publish the notice on the council&#39;s website. I what the East Riding of Yorkshire council will respond to my suggestion of this.</description><link>http://chris-osm.blogspot.com/2015/06/road-closure.html</link><author>noreply@blogger.com (Unknown)</author><thr:total>4</thr:total></item><item><guid isPermaLink="false">tag:blogger.com,1999:blog-179325926611299376.post-90974960632867640</guid><pubDate>Thu, 21 May 2015 20:27:00 +0000</pubDate><atom:updated>2015-05-21T21:27:55.127+01:00</atom:updated><title>Not Alone</title><description>I went out looking for new developments in East Yorkshire today.

I really want to find a way to show elevation in a way that is a bit different from a flat map. &lt;a href=&quot;http://chris-osm.blogspot.co.uk/2015/05/heights.html&quot;&gt;Working with the OS DEM data&lt;/a&gt; has whet my appetite to try something new, but first I need a map to work with.&lt;br /&gt;&lt;br /&gt;The most detailed DEM data I have is based on Ordnance Survey OpenData, so creating a map in the OS projection will be useful. I use &lt;a href=&quot;https://www.mapbox.com/tilemill/&quot;&gt;TileMill&lt;/a&gt; to create maps from OSM data. &lt;br /&gt;&lt;br /&gt;Firstly I needed OSM data in the Ordnance Survey projection. That means loading some OSM data into a fresh PostgreSQL database. I created a PostgreSQL database and, as usual, add the extension for PostGIS. this creates a table called spacial_ref_sys that includes the OS projection, amongst many others. I often add the hstore extension too, but this is a simple map so I didn&#39;t need it. &lt;br /&gt;&lt;br /&gt;&lt;blockquote class=&quot;tr_bq&quot;&gt;&lt;span style=&quot;font-family: &amp;quot;Courier New&amp;quot;,Courier,monospace;&quot;&gt;createdb -E UTF8 EYOS&lt;br /&gt;echo &quot;CREATE EXTENSION postgis;&quot; | psql -d EYOS&lt;/span&gt;&lt;/blockquote&gt;I loaded an extract of OSM data using the usual osm2pgsql utility except the projection was needed too to convert the data to OS projection as it is loaded.&lt;br /&gt;&lt;br /&gt;&lt;blockquote class=&quot;tr_bq&quot;&gt;&lt;span style=&quot;font-family: &amp;quot;Courier New&amp;quot;,Courier,monospace;&quot;&gt;osm2pgsql --slim -d EYOS -C 1024 ey.osm.pbf --proj 27700 &lt;/span&gt;&lt;/blockquote&gt;I decided to add a coastline, so that needed to be in OS projection too. OSM coastlines are handled differently from all other data. They are extracted from the main DB, checked for consistency and created into a shapefile for the world. This is known as processed_p.shp. I have my own copy with a cut-down version with only the British Isles in it to make rendering a bit quicker. I reprojected that to a copy in OS projection using OGR2OGR, part of the &lt;a href=&quot;http://www.gdal.org/&quot;&gt;Geospatial Data Abstraction Library&lt;/a&gt;.&amp;nbsp; &lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;blockquote class=&quot;tr_bq&quot;&gt;&lt;span style=&quot;font-size: x-small;&quot;&gt;&lt;span style=&quot;font-family: &amp;quot;Courier New&amp;quot;,Courier,monospace;&quot;&gt;ogr2ogr -t_srs &#39;EPSG:27700&#39; -s_srs &#39;EPSG:3857&#39; coast_bi_os.shp coast_bi.shp&lt;/span&gt;&lt;/span&gt; &lt;/blockquote&gt;&lt;br /&gt;Armed with all of this I could now start TileMill and add the layers I need for the map. Each of the layers, including the coast shapefile, needed a custom projection. This is:&lt;br /&gt;&lt;blockquote class=&quot;tr_bq&quot;&gt;&lt;span style=&quot;font-family: &amp;quot;Courier New&amp;quot;,Courier,monospace;&quot;&gt;+proj=tmerc +lat_0=49 +lon_0=-2 +k=0.999601 +x_0=400000 +y_0=-100000 +ellps=airy&amp;nbsp; +units=m +towgs84=446.448,-125.157,542.060,0.1502,0.2470,0.8421,-20.4894 +units=m +nodefs &lt;/span&gt;&lt;/blockquote&gt;&amp;nbsp;I got this from the PostgreSQL table postgis created above. Once I had designed the map as I wanted it I exported the Mapnik XML and ran it through Mapnik. I discovered that the Mapnik XML was not quite right. It needed to have the third line changed so the srs part matches the custom projection above. There doesn&#39;t seem to be a way to set this in TileMill, so a manual edit was needed.&lt;br /&gt;&lt;br /&gt;To run the Mapnik XML through Mapnik I used the following python code:&lt;br /&gt;&lt;br /&gt;&lt;blockquote class=&quot;tr_bq&quot;&gt;&lt;span style=&quot;font-family: &amp;quot;Courier New&amp;quot;,Courier,monospace;&quot;&gt;#!/usr/bin/python&lt;br /&gt;&lt;br /&gt;# generate a map image in OS projection epsg:27700&lt;br /&gt;&lt;br /&gt;import mapnik&lt;br /&gt;import sys, os&lt;br /&gt;def drawMap(filename, west,south,east,north):&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp; print(filename)&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp; sz = 5000&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp; ossrs = &quot;+proj=tmerc +lat_0=49 +lon_0=-2 +k=0.9996012717 +x_0=400000 +y_0=-100000 +ellps=airy +towgs84=446.448,-125.157,542.06,0.1502,0.247,0.8421,-20.4894 +units=m +no_defs&quot;&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp; m = mapnik.Map(sz,sz,ossrs)&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp; mapnik.load_map(m,&quot;osproj.xml&quot;)&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp; bbox = mapnik.Envelope(west,south,east,north)&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp; m.zoom_to_box(bbox)&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp; im = mapnik.Image(sz,sz)&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp; mapnik.render(m, im)&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp; view = im.view(0,0,sz,sz) # x,y,width,height&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp; view.save(filename,&#39;png&#39;)&lt;br /&gt;&lt;br /&gt;if __name__ == &#39;__main__&#39;:&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp; drawMap(&#39;cott.png&#39;,500000,430000,510000,440000)&lt;/span&gt;&amp;nbsp; &lt;/blockquote&gt;&lt;br /&gt;&lt;a href=&quot;http://3.bp.blogspot.com/-q1KxTY7-vtQ/VVC-YJbqKcI/AAAAAAAAB2w/jItfj1F679A/s1600/cott.png&quot; imageanchor=&quot;1&quot; style=&quot;clear: right; float: right; margin-bottom: 1em; margin-left: 1em;&quot;&gt;&lt;img border=&quot;0&quot; height=&quot;320&quot; src=&quot;http://3.bp.blogspot.com/-q1KxTY7-vtQ/VVC-YJbqKcI/AAAAAAAAB2w/jItfj1F679A/s320/cott.png&quot; width=&quot;320&quot; /&gt;&lt;/a&gt;&amp;nbsp;That long-winded projection was needed again. Notice the coordinates in the drawMap function are OS coordinates, not longitude and latitude. Everything must match the chosen projection.&lt;br /&gt;&lt;br /&gt;This gives me an image of the map in the OS projection, but the style could be any style you choose, though I&#39;d be wary of copying the OS style too closely. This will now match the DEM data if they are combined. My style is still a bit stark and only renders a few objects, but it is something to work with.&lt;br /&gt;&lt;br /&gt;Next I need to use it imaginatively. </description><link>http://chris-osm.blogspot.com/2015/05/heights-os.html</link><author>noreply@blogger.com (Unknown)</author><media:thumbnail xmlns:media="http://search.yahoo.com/mrss/" url="http://3.bp.blogspot.com/-q1KxTY7-vtQ/VVC-YJbqKcI/AAAAAAAAB2w/jItfj1F679A/s72-c/cott.png" height="72" width="72"/><thr:total>0</thr:total></item><item><guid isPermaLink="false">tag:blogger.com,1999:blog-179325926611299376.post-7879726695650290905</guid><pubDate>Fri, 08 May 2015 15:52:00 +0000</pubDate><atom:updated>2015-05-08T17:01:31.116+01:00</atom:updated><title>Heights</title><description>I&#39;ve been working on something locally for a while that benefits from maps. It needs height information displayed so I thought I&#39;d take a closer look at what was available, especially Digital Elevation Model (DEM) data&lt;br /&gt;&lt;br /&gt;OSM doesn&#39;t hold much height information, so when people want to display heights they turn to outside information. One such source is &lt;a href=&quot;http://www2.jpl.nasa.gov/srtm/&quot;&gt;Shuttle Radar Topography Mission data&lt;/a&gt; or SRTM. One Space Shuttle mission flew around the world and mapped the heights of the ground below using radar. This data has been published as open data. It is 1 second of arc data points for the USA and 3 seconds of arc data points for the rest of the world. This gives a height data point about every 90m for the UK. There are issues with this data with some places having voids where the radar return didn&#39;t register. It is usual for people who use this with OSM to render this data as contour lines or as hill shading or both as a way of visualising the height. I thought I&#39;d do some simple processing to be sure I understood the data format.&lt;br /&gt;&lt;br /&gt;&lt;table cellpadding=&quot;0&quot; cellspacing=&quot;0&quot; class=&quot;tr-caption-container&quot; style=&quot;float: right; margin-left: 1em; text-align: right;&quot;&gt;&lt;tbody&gt;&lt;tr&gt;&lt;td style=&quot;text-align: center;&quot;&gt;&lt;a href=&quot;http://3.bp.blogspot.com/-_F8ryzka1rU/VUzVAwh3-YI/AAAAAAAAB2Q/pUvs1sVer4A/s1600/h.png&quot; imageanchor=&quot;1&quot; style=&quot;clear: right; margin-bottom: 1em; margin-left: auto; margin-right: auto;&quot;&gt;&lt;img border=&quot;0&quot; height=&quot;320&quot; src=&quot;http://3.bp.blogspot.com/-_F8ryzka1rU/VUzVAwh3-YI/AAAAAAAAB2Q/pUvs1sVer4A/s320/h.png&quot; width=&quot;320&quot; /&gt;&lt;/a&gt;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td class=&quot;tr-caption&quot; style=&quot;text-align: center;&quot;&gt;SRTM&lt;/td&gt;&lt;td class=&quot;tr-caption&quot; style=&quot;text-align: center;&quot;&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/tbody&gt;&lt;/table&gt;The SRTM is published as a 1° square. I read the height values and displayed them as a shade of green since human eyes can distinguish more share variations in green than any other colour. Any voids I show as black There were nine pixels in this square) and any value with a small negative value (small so not a void) I show as blue. There&#39;s a lot of interest in this which I&#39;d not noticed looking at contours. The dark area top left is the Vale of York, the green area top centre is the bottom end of the Yorkshire Wolds You can just make out the Humber estuary just above the centre and to the right. The bright green area bottom right is part of the Lincolnshire Wolds. The valleys with tributaries feeding into the Vale of York are interesting. None of those exist as rivers or streams today, so I expect they are remnants of the retreating ice caps about ten thousand years ago when the ground was still permafrost so any melting water cut river channels. Today the water table is much lower with the chalk of the Wolds allowing water to drain into it.&lt;br /&gt;&lt;br /&gt;Next I looked at Ordnance Survey (OS) OpenData. They release height data as contours and spot heights in shape file format and DEM data too. The DEM is 50m spacing and should be free of voids. They use their own projection (EPSG:27700) for all of their data and this works better for the UK for some jobs. OS release some of their data in parcels based on their own grid. I am interested in a section of including Cottingham, &lt;a href=&quot;http://www.openstreetmap.org/#map=13/53.7776/-0.4249&amp;amp;layers=C&quot;&gt;a large village west of Hull&lt;/a&gt;. The OS square TA03 has Cottingham in the middle of it, so that is helpful.&lt;br /&gt;&lt;br /&gt;&lt;table cellpadding=&quot;0&quot; cellspacing=&quot;0&quot; class=&quot;tr-caption-container&quot; style=&quot;float: right; margin-left: 1em; text-align: right;&quot;&gt;&lt;tbody&gt;&lt;tr&gt;&lt;td style=&quot;text-align: center;&quot;&gt;&lt;a href=&quot;http://1.bp.blogspot.com/-M4suWzndaTM/VUzYDCEWEjI/AAAAAAAAB2c/lZQSUU3_5eU/s1600/o.png&quot; imageanchor=&quot;1&quot; style=&quot;clear: right; margin-bottom: 1em; margin-left: auto; margin-right: auto;&quot;&gt;&lt;img border=&quot;0&quot; src=&quot;http://1.bp.blogspot.com/-M4suWzndaTM/VUzYDCEWEjI/AAAAAAAAB2c/lZQSUU3_5eU/s1600/o.png&quot; /&gt;&lt;/a&gt;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td class=&quot;tr-caption&quot; style=&quot;text-align: center;&quot;&gt;OS TA03 square&lt;/td&gt;&lt;/tr&gt;&lt;/tbody&gt;&lt;/table&gt;I created a similar, image from the OS DEM data. I deliberately emphasised the height differences more than the SRTM image. The area is much smaller than the SRTM area but more detailed. bright green on the left is the edge of the Yorkshire Wolds. The blue line is the river Hull which cuts through the middle of the city of Hull. For comparison the bottom of the the blue smudge on the SRTM image is approximately where the OS image is. Again valleys are shown, though this time running west to east. Again they are dry (though very occasionally not which is part of what I&#39;m investigating). I&#39;ve decided that there is enough detail in the OS area and that it is big enough, perhaps with one more alongside it, to show what I want. so I&#39;ll work with that.&lt;br /&gt;&lt;br /&gt;More of what to do with it later.&lt;br /&gt;&lt;br /&gt;The python code to produce the SRTM image is here:&lt;br /&gt;&lt;blockquote class=&quot;tr_bq&quot;&gt;&lt;span style=&quot;font-size: xx-small;&quot;&gt;&lt;span style=&quot;font-family: &amp;quot;Courier New&amp;quot;,Courier,monospace;&quot;&gt;#!/usr/bin/env python&lt;br /&gt;# -*- coding: utf-8 -*-&lt;br /&gt;&lt;br /&gt;import struct&lt;br /&gt;from PIL import Image&lt;br /&gt;&lt;br /&gt;def getpix(val):&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;

This is a major obstacle to companies planning deliveries in the US by drone. I had wondered what kind of mapping such an enterprise would need. Where would such a delivery be made? If the address has a garden then that might be useful, but what if there are plants or garden furniture in the way? If the address has a driveway then that could be a good landing site, but if the delivery sits on the driveway what&#39;s to stop it being stolen or driven over by car arriving? If the address is an apartment on a street front will the parcel just be dumped on the street? How could a drone safely land on a sidewalk?&lt;br /&gt;&lt;br /&gt;When a delivery is made by hand it is handed over at a doorway, posted into a mailbox or left by a thinking person in a suitable place. A person can gain access to places like a shared lobby too. Can a drone do any of this?&lt;br /&gt;&lt;br /&gt;Maybe would-be delivery addresses need to designate a landing site for drones, maybe that would need signage and access restrictions and possibly even extra insurance. &lt;br /&gt;&lt;br /&gt;The more I think about it the mapping needed to control this would be very detailed and very specific. I suspect that the FAA ruling is the least of the problems this idea has.</description><link>http://chris-osm.blogspot.com/2015/02/drone-deliveries.html</link><author>noreply@blogger.com (Unknown)</author><thr:total>2</thr:total></item></channel></rss>

  				<description><![CDATA[I&#8217;m leading a Transition Town project to bring Legible London to Crystal Palace. You&#8217;ll have noticed these signs around central London, conspicuously absent across most of the rest of the capital: At the local Transition Town AGM, somebody suggested we should try to bring these to Crystal Palace. But why wait on TfL? Using OpenStreetMap and TileMill, we can try to produce our own similar map style and stick them up ourselves! Here is my prototype for the wide area map: You&#8217;ll notice dark blue lines along the edges of roads and though the park. Those are pavements and footpaths, and indicate where you can walk. Here&#8217;s a prototype for the more detailed map of the local area, with local points of interest, pedestrian crossings and bus stops: You&#8217;ll notice that some roads don&#8217;t show any pavements. Eagle-eyed locals may also spot missing cut-throughs and wonder about missing points of&#8230;<div class="more-link-wrapper"><a class="more-link" href="http://tomchance.org/2014/07/15/bringing-pedestrian-maps-to-crystal-palace/">Read More<span class="screen-reader-text">Bringing pedestrian maps to Crystal Palace</span></a></div>]]></description>

  				<description><![CDATA[Following yesterday&#8217;s post on making London more dense, Tim Lund suggested I do a slightly more sophisticated analysis. Planners in London use a metric called the Public Transport Accessibility Level, or &#8216;PTAL&#8217;, which does pretty much what you&#8217;d expect. Rules for things like car parking levels and the density of housing you should build are based on these, because obviously if you&#8217;re in central London you have no need for a car and you can justify quite tall blocks of flats, but in low rise suburbia with only sporadic bus services it&#8217;s accepted that more car parking and less dense housing is appropriate. So if you were to follow these rules, how much more housing could you build in London? First, I took the data for PTAL levels (the map on the left). Then I took my wards, sliced up to remove any areas that cannot be built on, cut&#8230;<div class="more-link-wrapper"><a class="more-link" href="http://tomchance.org/2014/01/18/densifying-london-part-two/">Read More<span class="screen-reader-text">Densifying London (part two)</span></a></div>]]></description>

  				<description><![CDATA[How do we build more homes in London? The Mayor&#8217;s latest exercise assessing needs suggests we need up to 690,000 over the next ten years, but a parallel exercise looking for land only came up with sites for 420,000 homes. The usual debate is whether or not we build in London&#8217;s greenbelt to make up the difference. But there are at least three good reasons not to go down this route to solve our problems: there are an awful lot of protected habitats that we really cannot build on; building sustainable developments around transport hubs and avoiding those habitats could only deliver (in Andrew Lainton&#8217;s estimation) 72,000 homes; and if we ignore these,  it could lead to more low density, car-dependent urban sprawl, which the greenbelt was established to prevent. The alternative, or perhaps complementary, approach is to make London more dense, particularly around transport hubs in sprawling, low density&#8230;<div class="more-link-wrapper"><a class="more-link" href="http://tomchance.org/2014/01/17/making-parts-of-london-more-dense/">Read More<span class="screen-reader-text">Making parts of London more dense</span></a></div>]]></description>

  				<description><![CDATA[In the past couple of months I&#8217;ve been able to combine work and my mapping hobby, working on a web site about air pollution in London. I&#8217;m going to be speaking about this at the October geomob meeting. I&#8217;m lucky enough to live in one of Europe&#8217;s most polluted cities. Air pollution causes more early deaths than obesity and road collisions, and is only bested by smoking. The Mayor published some really good open data on pollution levels, which of course is incomprehensible to ordinary folk. So despite having a sense that it&#8217;s not the cleanest city, Londoners don&#8217;t know all that much about the problem or how it could be solved. We want to help change that. Our first splash was a map showing the quantities of some major pollutants dropped on sections of roads across the capital, so Londoners could find out &#8211; how polluted is my road?&#8230;<div class="more-link-wrapper"><a class="more-link" href="http://tomchance.org/2013/09/12/mapping-dirty-london/">Read More<span class="screen-reader-text">Mapping dirty London</span></a></div>]]></description>

  				<description><![CDATA[I started writing this as an email to Richard Fairhurst, but then thought I&#8217;d post it to my blog. I wrote something on a similar theme just over a year ago. Richard, I just wanted to say that I thought your talk at the SOTMUS conference was spot on. But when you talk about the cycling community, I think there&#8217;s an important caveat missing. Lots of people in our mapping community (or lots of the 5% who do 95% of the mapping) are enthusiastic cyclists, but few in the enthusiastic cyclist community are mappers. I&#8217;ve not come across the London Cycling Campaign or any of the borough groups really getting involved with cycle mapping. Some members (myself included) do, but my impression is that most don&#8217;t. Despite embedding CycleStreets on their homepage and collaborating on a cycle parking campaign with them, I&#8217;ve never come across a big concerted push from&#8230;<div class="more-link-wrapper"><a class="more-link" href="http://tomchance.org/2013/06/12/getting-enthusiasts-into-openstreetmap/">Read More<span class="screen-reader-text">Getting enthusiasts into OpenStreetMap</span></a></div>]]></description>

  				<description><![CDATA[OpenEcoMaps, eco-living maps using OpenStreetMap data, is now working again. Hooray! I decided to sit down and work out why the OpenLayers interface wasn&#8217;t working and it turned out to be quite simple to fix. You can now browse around maps of low carbon energy generators in London, veggie restaurants in Edinburgh, allotments in Exeter, recycling facilities in Glasgow and more! The data is updated every hour, direct from OpenStreetMap, and is available on maps and downloadable/reusable KML and GeoJSON files. The code is also in Github, so you could set-up your own version for another country if you like. There are still some of the layers that aren&#8217;t working because the underlying data isn&#8217;t being extracted from OpenStreetMap properly. But I&#8217;m very glad that, after well over six months with it completely broken, the web site basically works again!]]></description>

  				<description><![CDATA[For almost a year now, my pet project OpenEcoMaps has been broken. The vagaries of unreliable XAPI servers meant the system couldn&#8217;t download OpenStreetMap data to create all the KML files, and (I think) some changes to OpenLayers meant the web maps also stopped working. It has taken me a long time to work up the energy to fix these. Today I can happily say one half of the system is now working again, and the underlying code is much improved. OpenEcoMaps KML files, and now GeoJSON files, are being created again. Hooray! I switched from XAPI to the Overpass API; grabbed JSON which enabled me to write a more powerful function to turn this into usable objects (for example building a complete Python object for an allotment merging data from relevant nodes, ways and relations); wrote a new library to create GeoJSON files; refactored everything else to fit with&#8230;<div class="more-link-wrapper"><a class="more-link" href="http://tomchance.org/2013/01/06/openecomaps-halfway-back/">Read More<span class="screen-reader-text">OpenEcoMaps halfway back</span></a></div>]]></description>

  				<description><![CDATA[The OpenStreetMap GB project aims to measure and improve the quality of OSM data in Great Britain, cleaning it up to get rid of silly little data errors, and to make this cleaned up version available in formats that local and central government types are used to. I have been exploring whether I could use the Web Features Service as an easier source for landuse data (see my previous blogs on making a map of London&#8217;s green spaces and analysing Southwark&#8217;s landuse, which both required a somewhat complicated process to get the data set). In the process I&#8217;ve found it&#8217;s actually a great way to identify gaps and problems in our data. Browse around the map on the OpenStreetMap homepage and you might think we have an impressive coverage of residential landuse, playing fields and parks. But probe around with the WFS and you can spot all sorts of missing&#8230;<div class="more-link-wrapper"><a class="more-link" href="http://tomchance.org/2012/11/08/spotting-problems-with-osm-gbs-web-service/">Read More<span class="screen-reader-text">Fixing problems with OSM-GB&#8217;s web service</span></a></div>]]></description>

  				<description><![CDATA[Following my map of London&#8217;s green and blue infrastructure, I have been working on some analysis of the land uses. I was inspired and encouraged to try this by Liliana&#8217;s interesting work called &#8220;imagining all of Southwark&#8220;. Lili and Ari have managed to get the council to release lots of data on properties and car parking, and they are producing analysis of this data by postal code area and by street. They haven&#8217;t managed to get anything on land uses, so I thought, why not produce this with OpenStreetMap data? A few evenings later, here is the result shared on Google docs (direct link) covering the eight postal code areas that between them cover most of the borough (SE1, SE5, SE15, SE16, SE17, SE21, SE22, SE24): What the data means The &#8220;summary&#8221; worksheet shows the total land area, expressed in hectares (10,000 m2), for various different types of land coverage.&#8230;<div class="more-link-wrapper"><a class="more-link" href="http://tomchance.org/2012/11/02/analysing-southwarks-natural-geography/">Read More<span class="screen-reader-text">Analysing Southwark&#8217;s natural geography</span></a></div>]]></description>

The data I used was: OpenStreetMap shapefiles for most features from Geofabrik, supplemented by&#8230; Manually retrieved commons and marshes using the Overpass API (not yet present in Geofabrik shapefiles) Natural England shapefiles for orchards, deciduous woodlands and sites of special scientific interest Ordnance Survey Boundary-Line shapefiles for the Greater London and London borough boundaries There&#8217;s no reason the Natural England data couldn&#8217;t be manually added to OpenStreetMap, giving us a complete dataset of natural features. I just chose to get on and do it this way rather than wait, or try to add all the data across areas&#8230;<div class="more-link-wrapper"><a class="more-link" href="http://tomchance.org/2012/10/26/londons-natural-geography/">Read More<span class="screen-reader-text">London&#8217;s natural geography</span></a></div>]]></description>

  								<content:encoded><![CDATA[<p>This year, with Leeds City Council I developed <a href="http://LeedsAdultLearning.co.uk" target="_blank" rel="noopener">LeedsAdultLearning.co.uk</a> which is a course finder for about 300 courses by the City and run by a number of providers and dozens of venues. It offers a range of first step courses for adults, such as basic IT skills, ESOL, caring and crafts. Within the first 24 hours of launch it received over 3000 visits, in the first month, it had over 25,000 visits, with the average user spending three minutes on the site.  The code&#8217;s up on my <a href="https://github.com/timwaters/learninginleeds">LearningInLeeds GitHub repository</a>.</p>

  <p>The project evolved from a LCC Innovation Lab &#8211; similar to the Leodis project I also worked on. The key idea is that it was designed to be a pilot or prototype project, small in scope and quick to develop, it would aim to be an aspirational example of how the City can work with the Council and open data to make good IT products. The adult education department were fully engaged with the development and design of the project, giving feedback, priorities. This engagement was really welcome and I think the experts say its crucial to any successful agile project. The department didn&#8217;t have any online course finder before so this was bringing something new, and needed to them.</p>

  <h3>Features</h3>
  <ul>
  <li>Automatic imports of courses from Data Mill North (open data site)</li>
  <li>Full text search with support for sounds like and spelling mistakes</li>
  <li>Geographical, near searches</li>
  <li>Bus and walking directions to the start of the course from any point</li>
  <li>Add to calendar links for course start</li>
  <li>Showing courses by topics or categories</li>
  <li>Responsive and mobile friendly.</li>
  <li>Simple CMS admin UI for staff to update text pages, change records etc</li>
  <li>Caching of external API requests, front page and CMS pages</li>
  <li>Recent searches kept</li>
  </ul>
  <h3>Technology</h3>
  <ul>
  <li>Ruby on Rails</li>
  <li>Devise and Active Admin for admin UI</li>
  <li>Postgresql, PostGIS and pg_search for db, geo, full text stuff</li>
  <li>Bootstrap for front end user interface layout, CSS etc</li>
  <li>Transport API, Bing Transit, Mapzen for journey planning and geocoding etc</li>
  </ul>
  <h3>Future</h3>
  <p>The project could be altered for other organisations, and it could be altered to include the whole range of courses on offer for adults across the city region. I think usage metrics would need to be done to see what users actually do on the site, and whether the journey planning is useful. Adding extra information about course duration,  how many times a week / month etc would be good. Making it more mobile friendly could be looked at, including making a mobile only app.</p>

  								<content:encoded><![CDATA[<h2>Introduction</h2>
  <p><a href="http://newcloudatlas.org" target="_blank">The New Cloud Atlas</a>, (<a href="http://newcloudatlas.org" target="_blank">newcloudatlas.org</a>) is a global effort to map each data place that makes up the cloud in an open and accountable way. It&#8217;s a project to find and map each warehouse data centre, each internet exchange, each connecting cable and switch. Anything of any physical significance in the operation of the cloud should be observed in some way, and recorded for everyone to see and use. Data is stored in OpenStreetMap and users can map things using the on site iD editor with custom telecoms presets for the first time. Map tiles with two styles have been produced and have now made visible this hidden infrastructure. <a href="http://newcloudatlas.org" target="_blank">http://newcloudatlas.org</a></p>
  <p>The New Cloud Atlas, named after the nineteenth collaborative scientific data collection project, is about understanding and making visible the hidden &#8220;Cloud&#8221;. Although most of these telecoms features are in the open and in plain sight, many are missing from open datasets or may be considered sensitive. Telecoms infrastructure has immense importance in connectivity and power in our connected world  &#8211; the more connected a place is the more benefits it has. Indeed the lines of fibre optic backbone have become the new ley lines of the 21st Century powering the forces behind a new Psychogeography of places.</p>
  <p>A bit about the name: The First Cloud Atlas was published in 1896 by the Permanent Committee of the first International Meterological Congress. Cloud weather observatories around the world were able to share consistent observations of the clouds and observe weather systems whose scale stretched over national boundaries. The publication of the International Cloud Atlas represented a move beyond national concerns and boundaries to an international perspective.</p>
  <p>In addition to its important role in the predicting the weather, the vision is a surprisingly early call for infrastructural globalism and worldwide collaboration:</p>
  <blockquote cite="1873 report from the first International Meteorological Conference"><p>&#8220;If there be any branch of science in which work on a uniform system can be especially useful and advantageous, that branch is the inquiry into laws of weather, which, from its very nature, can only be prosecuted with a hope of success by means of very extensive observations embracing large areas, in fact, we might almost say, extending over the whole surface of the globe”</p></blockquote>

  <p>The Cloud X-Ray style, shown above was partially inspired by Kosmtik&#8217;s data inspector style, and it shows polygons that are enlarged at low zooms. Polygons should appear to be the same size on the screen as you zoom in. It gives a sci-fi cartography, but I find it very useful finding clusters of mapped features, as all features are shown at all zoom levels.</p>

  <h2>Background</h2>
  <p>The New Cloud Atlas is a project initiated by experimental media technologist, artist and designer <a href="http://bendalton.noii.net/" target="_blank">Ben Dalton</a> with the design and research studio of <a href="http://www.afjdstudio.net/" target="_blank">Amber Frid-Jimenez</a> and <a href="http://www.afjdstudio.net/" target="_blank">Joe Dahmen</a>, and myself. Ben writes about the project &#8211; with the main idea that it&#8217;s about understanding what the Internet actually is in physical terms, rather than as something that remains clouded and mysterious:</p>
  <blockquote><p>The first appearance of the internet cloud was in network diagrams. The cloud symbol was used to stand in for complexity. The cloud embodied something of the way that the internet functions. The internet was designed to be &#8216;end-to-end&#8217;, so computers are meant to be able to connect to each other without interference as the message passes through a network of interconnections. Only the end points are meant to matter. The clouds here represent &#8216;something in the middle that is too complex to draw here&#8217;, a kind of neutral space through which information passes. It is an act of simplification, but it also contains an implicit statement that &#8216;the cloud will look after itself&#8217; that this thing is going to carry on being there.</p>
  <p>Beclouding is deliberately making something more confusing, in order to obfuscate or conceal its meaning. The use of the cloud has shifted in digital systems. The idea that &#8216;this is too complicated to think about&#8217; has been moved front and centre and converted into a business model, shedding its innocence along the way. Through a sleight of hand, the cloud sometimes appears as a platform, and sometimes a material. This narrative rests on the idea that the services are to be trusted, and they can take care of themselves on your behalf. We trust them with our emails and our childhood photographs and our meeting plans and whatever else we use the cloud for. In this new definition of the cloud, there is a statement that &#8216;this is too complex to deconstruct or critique&#8217;. You shouldn&#8217;t try to look in to the cloud and see what&#8217;s there. It&#8217;s made up of vapour, and it&#8217;s not to be interrogated. Better to simply observe it from a distance and admire it at sunset.</p>
  <p>Once the domain of national governments, information infrastructure is increasingly constructed, operated, and maintained by major multinational corporations. These corporations, which include Google, Facebook, Amazon, Apple, and Microsoft, have a similar vested interest in maintaining control over of the flow of goods and information once exercised by national governments, but a reach at once more extensive and less transparent.</p></blockquote>
  <h3>Psychogeography</h3>
  <p>Regular readers may know of my interest in Psychogeography. The British Psychogeography of the 90s employed Ley Lines and &#8220;Magico-Marxism&#8221; using the language of the occult to explain the unknown forces of power at work in space and in places. I&#8217;m developing the idea that the new lines of power in the 21st Century are of Information &#8211; and the actual lines of light that transmit these bits of data, and the buildings that house them. More about that in walk or talk later on this year!</p>
  <p>Another more obvious connection with psychogeography is the hidden in plain sight angle. These passageways of the internet are often marked, on manhole covers, in mobile phone masts, in big buildings in light industrial estates, but they are utterly overlooked. They may travel along the margins, along canals or train tracks. They are also sited in classic psychogeographical &#8220;liminal&#8221; spaces &#8211; beaches, margins of rural and urban, wasteland, on top of tower buildings etc.</p>
  <h4>OpenStreetMap and the Telecoms WikiProject</h4>
  <p>OpenStreetMap allows anything that exists and can be verified to be mapped. There is no notability rule that Wikipedia has, for example. So it allows manhole covers to be mapped in detail, it allows telephone lines and the assorted street cabinet boxes that crowd our pavements. You might get feedback as to how to map these features and you might get funny comments about why these features are being mapped (and indeed, mapping with OpenStreetMap is voluntary!) but pretty much all OSM mappers will agree that these features shouldn&#8217;t be excluded.</p>

  <p>Telecoms features in OpenStreetMap haven&#8217;t been well mapped before. This is both good and bad in that the taxonomy (or folksonomy to be more accurate)  &#8211; the tags that describe these features -have not been standardized. We have the opportunity to define the tags, or at least standardize some of them to be more consistent across similar telecoms infrastructure features.</p>
  <p>I started <a href="https://wiki.openstreetmap.org/wiki/WikiProject_Telecoms" target="_blank">WikiProject Telecoms</a> on the OSM Wiki, so please go there to see how to map and tag features &#8211; and if you are a telecoms, mapping or tagging specialist please suggest better ways to map these features! <a href="https://wiki.openstreetmap.org/wiki/WikiProject_Telecoms" target="_blank">https://wiki.openstreetmap.org/wiki/WikiProject_Telecoms</a></p>
  <p>The current features being rendered in the New Cloud Atlas map are:</p>
  <ul>
  <li>Data Centres</li>
  <li>Telephone Exchanges</li>
  <li>Manhole covers</li>
  <li>Telephone poles and wires</li>
  <li>Submarine cables etc</li>
  <li>Telecoms towers, masts, and antennae</li>
  <li>Street Cabinets</li>
  </ul>
  <p>Underground features may be more difficult to map &#8211; so we are relying on manhole covers which often show what its use and who operates the cable underneath (in the UK at least) &#8211; and those markings sprayed by utility companies, and some data imports. If you don&#8217;t know where an underground cable goes its probably best to leave it out.</p>
  <p>You might have noticed that many of the options include sound and heat for the street cabinets. One of the side effects of today&#8217;s modern fibre optic street cabinets is that they are often installed with more power needs than copper wire ones &#8211; and so they need a fan. Often the cabinets are warm to the touch and sometimes they make a quite loud drone sound. This type of data can be useful, I have heard, to people who are vision impaired. Sound and touch can help orientate people in space.</p>

  <p>It&#8217;s probably worth talking a little bit about the privacy and secrecy issues. Although the project isn&#8217;t about getting releases of data from companies and governments, and it&#8217;s not about uncovering the secret installations, it is about collaboratively mapping the world. Almost all of the information that will make up the New Cloud Atlas will be found in the field or in public information sources.</p>
  <p>You may be reminded of a story in 2003 (2 years after 9/11) of <a href="https://twitter.com/SeanGorman" target="_blank">Sean Gorman</a>&#8216;s PhD dissertation that <a href="http://seclists.org/isn/2003/Jul/28" target="_blank">the US Government wanted to make classified</a> as although it contained only publicly available information (about the Internet connections in the US) he analyzed the data to identify the weak links &#8211; weaknesses that, for example, a disaster could take out or a terrorist could exploit.  Officials in the US Govt said that his dissertation should be burnt! Sean successfully graduated and started a mapping company with the DHS as clients. (I actually ended up working there at FortiusOne / GeoIQ several years after that for a bit). Now of course open data and open analysis is encouraged and promoted by governments (and following this trend check out Sean&#8217;s new startup <a href="http://timbr.io/">Timbr.io</a>).</p>
  <p>You may also recall stories about how many national mapping agencies removed military bases (such as Aldermaston, or Greenham Common in the UK) from their paper maps &#8211; even when these bases were signed from the motorways and major roads and had nice big clear signs outside the fences.  A relic from the Cold War, perhaps. It appears to me that even in this current year the Ordnance Survey mislabels the Menwith Hill USAF/RAF Listening Base in North Yorkshire as just &#8220;Menwith Camp&#8221; with no indication of it&#8217;s real name, activity nor landuse (as compared to OpenStreetMap for example).</p>
  <p>At this point, if you are curious, we should evoke the classic 1996 Wired Article by Neal Stephenson: <a href="http://Mother Earth Mother Board" target="_blank">Mother Earth Mother Board</a> <a href="http://Mother Earth Mother Board" target="_blank">http://www.wired.com/1996/12/ffglass/</a> It&#8217;s essential if you are interested in reading more about the geo political and technology of international internet cable laying. It&#8217;s also a great read in general.</p>

  <h2>Development Notes</h2>
  <p>Code for the site is on github: <a href="https://github.com/timwaters/new_cloud_atlas" target="_blank">https://github.com/timwaters/new_cloud_atlas</a></p>
  <p>Mapnik / Kosmtik Style file and processing notes also on github: <a href="https://github.com/timwaters/cloud_mapping" target="_blank">https://github.com/timwaters/cloud_mapping</a></p>
  <h4>Mapnik X-Ray Style</h4>
  <p>Of possible interest to mapnik style geeks could be the use of the scale denominator and PostGIS ST_Scale commands to scale up building polygons so that they appear to be the same size regardless of the zoom. If anyone wants to fix this to make it work better, please let me know!</p>
  <pre>select st_translate(st_scale(way, (!scale_denominator! * 0.00028) - (5 - z(!scale_denominator!)) ,
   (!scale_denominator! * 0.00028) - (5 - z(!scale_denominator!)) ), 
  st_x(st_centroid(way))*(1-( (!scale_denominator! * 0.00028) - (5 - z(!scale_denominator!)) )), 
  st_y(st_centroid(way))*(1-( (!scale_denominator! * 0.00028) - (5 - z(!scale_denominator!)) ))) as way,
   building AS type FROM planet_osm_polygon WHERE (building='data_center' ) AS data",</pre>
  <h4></h4>
  <h4>OSM Tile Generation</h4>
  <p>Tiles are kept up to date at around 15 minutes with the central OSM database. Occasionally a full planet import is done. I think I could use Lua scripting to ensure that the database remains lean. The system uses TileStache to enable the UTFGrids for the popups. Essentially we filter out a lot of stuff from the OSM database:</p>
  <ol>
  <li>Convert an osm.pbf file to an o5m file
  <pre>./osmconvert  planet-latest.osm.pbf -o=planet.o5m</pre>
  </li>
  <li> Filter the o5m file to an .osm file
  <pre>./osmfilter planet.o5m --parameter-file=cloud_mapping/osmfilter_params.txt &gt; planet.filtered.osm</pre>
  </li>
  <li>Import the .osm file into the database using the custom osm2pgsql Style
  <pre> osm2pgsql --slim -d gis planet.filtered.osm -S cloud_mapping/default.style</pre>
  </li>
  <li>Set up replication using Osmosis and osm2pgsql to get changes from OSM db
  <pre>osmosis --read-replication-interval  --simplify-change --write-xml-change changes.osc.gz
  osm2pgsql -d gis -S default.style -s -C 800 -a changes.osc.gz -e10-19 -o expire_e10-19.list</pre>
  <h2></h2>
  </li>
  </ol>

  								<content:encoded><![CDATA[<p>Last autumn I popped up to Edinburgh from the North of England for State of the Map Scotland conference. Together with Edinburgh College of Art in Evolution House participants took part in series of workshops <a href="http://wiki.openstreetmap.org/wiki/State_of_the_Map_Scotland_2015/Day_5#Workshop_1_:_Getting_Crafty_with_Map.Makars" target="_blank">&#8220;Map.Makars&#8221;<br />
  </a><br />
  I took part in a memory map of the city. The rules were: no looking at other maps, the map should include the venue, the castle, the train station. We drew, from memory the city on large pieces of paper. <a href="http://www.livingwithdragons.com/2015/10/the-highlights-of-scotland" target="_blank">Gregory</a> scanned/photographed these and put these on mapwarper.net to stretch them to fit. he then combined these together with an interactive and animated transparency control to create the <strong>Hand Drawn Map Collider &#8220;<a href="http://www.livingwithdragons.com/maps/nomap-map/" target="_blank">No-map Map</a>&#8220;</strong> Give it a whirl! <a href="http://www.livingwithdragons.com/maps/nomap-map/" target="_blank">http://www.livingwithdragons.com/maps/nomap-map/ </a></p>

It&#8217;s an open source, fast, temporal enabled, versioned gazetteer using open data. It also works as a platform for a fully featured function-laden historical gazetteer.</p>
  <p>You can check out the official release at the <a title="https://github.com/LibraryOfCongress/gazetteer/" href="https://github.com/LibraryOfCongress/gazetteer/" target="_blank">Library of Congress&#8217;s GitHub</a> page, and for issues, documentation and development branches on <a title="https://github.com/topomancy/gazetteer" href="https://github.com/topomancy/gazetteer" target="_blank">Topomancy&#8217;s Gazetteer project</a> site.</p>
  <p>Here is an introduction to the project giving an overview and discussion of the challenges and listing the features of this software application. Enjoy!</p>
  <p>DEMO: Head over to <strong><a title="http://loc.gazetteer.us/" href="http://loc.gazetteer.us/" target="_blank">http://loc.gazetteer.us/</a> </strong>for the Digital Gazetteer &#8211; a more global gazetteer and to <strong><a title="http://nypl.gazetteer.us/" href="http://nypl.gazetteer.us/" target="_blank">http://nypl.gazetteer.us/</a></strong> for the NYPL&#8217;s  NYC focused historic gazetteer. If you want to try out the conflation, remediation and administrative roles, let us know at <em>team@topomancy.com</em></p>
  <h2>Introduction, Overview, Features</h2>
  <p>A gazetteer is a geographic dictionary sometimes found as an index to an atlas. It&#8217;s a geographic search engine for named places in the world. This application is a temporal gazetteer with data source remediation, relations between places and with revisions which works with many different data sources. It&#8217;s fast, written in Python and uses ElasticSearch as a database. The application was primarily written as a Digital Gazetteer for the Library of Congress&#8217;s search and bibliographic geographic remediation needs and was also developed for the New York Public Library&#8217;s Chronology of Place project. It is currently being used in production by the Library of Congress to augment their search services. The software is MIT licensed.</p>

  <h3>Relations between places</h3>
  <p>These are:<br />
  * Conflates (A is the same place as B)<br />
  * Contains (A contains B spatially)<br />
  * Replaces (A is the same as B but over time has changed status, temporal)<br />
  * Subsumes (B is incorporated into A and loses independent existence, temporal)<br />
  * Comprises (B comprises A if A contains B, along with C,D and E)</p>
  <p>We will delve into these relationship concepts later</p>
  <h3>Site Admin</h3>
  <p>* GeoDjango administrative pages<br />
  * Administrative Boundary operations<br />
  * Batch CSV Import of places for create / Update<br />
  * Edit feature code definitions<br />
  * Edit groups and users and roles etc<br />
  * Edit layers (tile layers optionally shown for some features)<br />
  * Add / Edit data origin definitions</p>

  <h2>Background, Requirements and Challenges</h2>
  <h3>Library of Congress and Bibliographic Remediation</h3>
  <p>The Library has lots of bibliographic metadata, lots of geographic information, much of it historical, almost all of it is unstructured.<br />
  For example, they have lots of metadata about books, where it was published, the topics, subjects etc. They want to try and improved the quality of the geo information associated with the metadata, and to augment site search.</p>
  <p>So the library needs an authoritative list of places. The Library fully understands the needs for authoritative lists &#8211; they have authority files for things, ideas, places, people, files etc, but no centralised listing of them, and where there are geographic records there may be no actual geospatial information about them.</p>
  <h3>Initial Challenges</h3>
  <p>So we start with a simple data model, where a named location on the Earth&#8217;s surface has a name, a type and a geometry. All very simple right? But actually it&#8217;s a complex problem. Take the name of a place, what name to use? What happens if a place has multiple names, and what happens if it has multiple records to describe the same place? Taxonomies are also a large concern, for example establishing a set schema for every different type of feature on the earth is not trivial!</p>
  <p>What&#8217;s the geometry of a place? Is it a point, is it a polygon, and at what scale? For administrative datasets, it&#8217;s often impossible to get a good detailed global administrative dataset. Often in many places the data is not there. Timeframe and temporal gazetteers are an another large area for research (see OpenHistoricalMap.org if this intrigues you!). But the way we describe places in time is very varied, for example &#8220;in the 1880&#8217;s&#8221; or &#8220;mid 19th Century&#8221; or &#8220;1 May 2012 at 3pm&#8221;. What about places which are vague or composed of other places, like &#8220;The South&#8221; (of the US) &#8211; how would a gazetteer handle these? And the relationships between places is another very varied research topic.</p>
  <h3>Approach</h3>
  <p>So we think the project has tried to address these challenges. For names, the system can accept multiple additional alternate names, and conflation enables the fixing of multiple records together so that the results shows the correct authoritative results. The Digital Gazetteer allows places to have any type of geometry (e.g. point, line, polygon) where all the database needs is a centroid to make search work. For temporal support, places have datestamp for start and end dates but crucially there is in addition fuzzy start and ends specified in days. This enables a place, for example to have a fuzzy start date (sometime in the year 1911) and a clear end date (23 May, 1945). For &#8220;The US South&#8221; example &#8211; composite places were created. The system generates the union of the composite places and makes a new one. The component places still exist &#8211; they just have a relationship with their siblings and with their new parent composite place. This brings us to how the Digital Gazetteer handles relations between places.</p>

Composite Place</p></div>
  <h3>Relationships</h3>
  <p>Let&#8217;s look a bit more in detail about the relationship model. Basically the relationships between places help in conflation (reducing duplicate records) and in increasing search accuracies. The five relationships are as follows:</p>
  <p>* Conflates<br />
  * Contains<br />
  * Replaces<br />
  * Subsumes<br />
  * Comprises</p>
  <h3>Conflates</h3>
  <p>This is the most common relationship between records initially. It effectively is an ontological statement that the place in one record is the same as described in another record, that entries A and B are the same place. It&#8217;s a spatial or a name type of relation. For example, if we had 5 records for Statue of Liberties, and all 4 were conflated to the one record, when you searched for the statue you&#8217;d get the one record, but with a link to each of the other four. Conflates hides the conflated record from search results.</p>
  <h4>Contains</h4>
  <p>Contains is a geographical relationship. Quite simply, Place A contains Place B. So for example, the town of Brighton would contain the Church St. Matthews.</p>
  <h4>Replaces</h4>
  <p>Replaces is mainly a temporal relation, where one place replaces another place if the other place has significantly changed status, name, type or boundary. For example, the building representing the Council Offices of the town from 1830-1967 is replaced by a bank.</p>
  <h4>Subsumes</h4>
  <p>Subsumes is mainly a temporal relation. Where a place A becomes incorporated into another place B and loses independent existence. For example, the ward of Ifield which existed from 1780 to 1890 becomes subsumed into the ward of Crawley.</p>
  <h4>Comprises</h4>
  <p>Comprises is primarily a spatial or name relation. Place A comprises place B along with place C,D and E. This relation creates composite places, which inherit the geometries of the component places. For example, &#8220;The US South&#8221; can be considered a composite place. This place is comprised of Virginia, Alabama etc. Virginia in this case comprises &#8220;the US South&#8221;, and the composite place &#8220;The US South&#8221; has the union of the geometry of all the places it is comprised by.</p>
  <h2>Data Sources</h2>
  <p>OpenStreetMap (OSM), Geonames, US Census Tiger/Line, Natural Earth, Historical Marker Database (HMDB), National Historical GIS (NHGIS), National Register of Historic Places Database (NRHP) and Library of Congress Authority Records</p>
  <h3>Further Challenges</h3>
  <p>Automatic Conflation</p>
  <p>There remains two main areas for future development and research &#8211; Automatic Conflation and Search Ranking. Since there are multiple datasets, there will of course be the same record for the same place. The challenge is how to automatically find the same place from similar records by some kind of search distance. For example, by distance from each other, distance geographically, and in terms of name and place type. Tricky to get right, but the system would be able to undo any of the robots mistakes. Further information about this topic can be found on the GitHub wiki: <a title="https://github.com/topomancy/gazetteer/wiki/Conflation" href="https://github.com/topomancy/gazetteer/wiki/Conflation" target="_blank">https://github.com/topomancy/gazetteer/wiki/Conflation</a></p>
  <h3>Search Ranking</h3>
  <p>By default the gazetteer uses full text search which also takes into account alternate names and administrative boundaries, but there is a need to float up the more relevant places in the search results. We can also sort by distance from the search centre if doing a search within geographic bounds, which is used for helping find similar places for conflation. We could probably look at weighting results based on place type, population and area, although population and area for many urban areas in the world may not be available. One of the most promising areas of research is using Wikipedia request logs as a proxy for importance &#8211; places could be more important if they are viewed on Wikipedia more than other places.</p>
  <h2>Further Issues</h2>
  <p>Some other issues which I haven&#8217;t got space to go into here include: synchronising changes up and downstream to and from the various services and datasets. Licensing of the datasets could be looked at especially if they are being combined. What level of participation in the conflation and remediation steps should a gazetteer have, which depends on where the gazetteer is based and who it is being used for.</p>
  <h1>NYPL Chronology Of Place</h1>
  <p>I mentioned at the beginning of the post that the New York Public Library (NYPL) was also involved with the development of the Gazetteer. That project was called The Chronology of Place, and as the name suggests is more temporal in nature. But it&#8217;s also more focused geographically. Whereas the LoC are interested in the US and the World as a whole, the NYPL&#8217;s main focus is the City of New York. They wanted to deep dive into each building of the city, exploring the history and geography of buildings, streets and neighbourhoods.</p>

NYPL Chronology of Place</p></div>
  <p>Thus the level of detail was more fine grained, and is reflected in some custom default cartography in the web application client. A nondescript building in a street in a city for example are not usually considered a &#8220;place&#8221; worthy of a global gazetteer but for the NYPL each building was significant. Also, the NYPL has extensive access to historical maps via the NYPL Map Warper which Topomancy developed for them, and around a hundred thousand digitized vector buildings from these historical map atlases. This data, along with data from the city were able to be added to the system to augment the results. Additional data sources include the Census&#8217;s Historical Township boundary datasets, NYC Landmarks Preservation Commission Landmarks and NYC Building Footprints.</p>
  <p>There were two additional features added to the application for the NYPL&#8217;s Chronology of Place. The first was expanding the data model to include street addresses, so that a building with no name can be used, and the second was to display raster tile layers (often from historical maps) for specific features. Thus,the building features which were digitized from the historical maps were able to be viewed alongside the source raster map that they came from.</p>

It&#8217;s also famous for being the home of the <a href="http://wiki.openstreetmap.org/wiki/Karlsruhe_Schema" target="_blank">Karlsruhe Addressing Scheme</a> &#8211; an example of a folksonomy tagging convention that everyone pointed to and adopted, due to the great mappers there &#8211; including the folks from <a href="http://geofabrik.de" target="_blank">Geofabrik.de</a> who also organised the conference. Here are some notes from the conference:</p>
  <h1><strong>Nature of the conference</strong></h1>
  <p>The European conference seemed much more intimate with a focus on developer and contributors  &#8211; compared to the US Conference which I think had more end users and people sent there by their bosses for their company. Pretty much every single session was on topic (except for the closing buzzword laden keynote!)  &#8211; and as such there were no enlightening talks about psychogeography, general historical mapping, or other geospatial software. It was pure OSM.</p>
  <p>All the <a href="http://www.sotm-eu.org/en/program" target="_blank">talks are online</a> and the <a href="https://www.youtube.com/channel/UCx9HXUNf0fa-43uQVyzWmGg" target="_blank">video recordings are on youtube</a> and I encourage you to view them.</p>
  <h2><strong>3D maps</strong></h2>
  <p>3D Maps, such as <a href="https://mapzen.com/vector-map" target="_blank">Mapzen</a> and <a href="http://osmbuildings.org/?lat=52.52111&amp;lon=13.40988&amp;zoom=16" target="_blank">OSMBuildings</a> were prominent &#8211; and both showed off some very creative ways of representing 3D maps.</p>
  <h2><strong>Geocoder and Gazetteers</strong></h2>
  <p>The only track in the conference &#8211; this was full of gazetteers with an announcement from <a href="http://geocoder.opencagedata.com/" target="_blank">OpenCage</a> and MapZen &#8211; all appear to be using ElasticSearch &#8211; same as we (Topomancy) did last year for the NYPL and Library of Congress. <a href="http://loc.gazetteer.us/" target="_blank">Check out gazetteer here</a>.</p>
  <h2><strong>Other stuff</strong></h2>
  <p><strong>Trees</strong> &#8211; Jerry did a talk about mapping trees &#8211; about how they were represented in historical maps previously, and how we can use SVG symbols to display woods and trees in a better way. Jerry lead an expedition and workshop on the morning of the hack day to show participants the different habitats, surface types and variance in the environment that mappers could take into consideration.</p>
  <p><strong>Mapbox WebGL</strong> &#8211; Constantine, a European engineer of Mapbox did a fascinating talk about the complexities of the technical challenges with vector tiles and 3D maps. I really enjoyed the talk.</p>

  <p><strong><a href="http://opengeofiction.net/#map=11/-31.4547/176.9108" target="_blank">OpenGeoFiction</a> </strong>&#8211; using the OSM stack to create fictional worlds  &#8211; not fantasy or science fiction, but amazing experiments in amateur planning, utopian visions and creative map making. <a href="http://opengeofiction.net/#map=11/-31.4547/176.9108" target="_blank">OpenGeoFiction.net</a></p>
  <blockquote><p>The fictional world of Opengeofiction is thought to be in modern times. So it doesn&#8217;t have orcs or elves, but rather power plants, motorways and housing projects. But also picturesque old towns, beautiful national parks and lonely beaches.</p></blockquote>
  <p>I love this project!</p>
  <p><strong>Vector Tiles</strong> &#8211; Andy Allan talked about his new vector tile software solution <a href="http://www.thunderforest.com/" target="_blank">ThunderForest</a> &#8211; being one of the only people to know the ins and outs of how Mapbox do the Mapnik / TileMill vector magic. <a href="http://www.thunderforest.com/" target="_blank">ThunderForest</a> powers the cycle map. Vector maps has lots of advantages and I think we&#8217;d probably use it for OpenHistoricalMap purposes at some stage. <a href="http://www.gravitystorm.co.uk/andy/" target="_blank">Contact Andy</a> for your vector mapping and online cartographic needs!</p>
  <p><strong>POI Checker</strong> &#8211; from the same house as WheelMap.org comes <a href="http://poichecker.de/" target="_blank">POI Checker</a> &#8211; it allows organisations to compare their data with data in OSM  &#8211; and gives a very neat diff view of Points of Interests. This could be a good project to follow.</p>
  <h2><strong>Historical Stuff</strong></h2>
  <p><strong>OpenHistoricalMap</strong> There were a few things about historical maps in the conference, although in my opinion less than at any other SOTM previously. I did a lightning talk about OpenHistoricalMap and completely failed to mention the cool custom <a href="http://leatherwood.herokuapp.com" target="_blank">UK centric version of the NYPL&#8217;s Building Inspector</a>.</p>
  <p><strong>Opening Keynote</strong>  &#8211; this was peppered with the history of the city and gave a number of beautiful historical map examples. Watch the video.</p>
  <p><strong><a href="http://maproulette.org/" target="_blank">Map Roulette</a> v2</strong> &#8211; Serge gave a talk about the new version of <a href="http://wiki.openstreetmap.org/wiki/MapRoulette" target="_blank">Map Roulette</a>  &#8211; it is being customised to be able to run almost any custom task on the system. We chatted a the hack day to see if the tasks from the Building Inspector could be a good fit into the new Map Roulette &#8211; I will look into this!</p>

  <p>This weekend there was a data hackday at the UK&#8217;s NHS Information Centre for Health and Social Care in the centre of Leeds.</p>

  <p>There&#8217;s a wealth of data on their website , but it was given to us as a mysql database, and we were able to enter remotely. On the first day I poked around the data and had a thought.</p>
  <h2><strong>Hackdays</strong></h2>
  <p>I often spend the first part of any hackday wondering what to do, and twiddling thumbs. I find that hackdays become for me a type of busman&#8217;s holiday &#8211; and this hackday was particularly geographical in nature. Most of the entries had some kind of data on map component. I think that these types of analyses, whilst being very smart and interesting &#8211; and may be exactly what the judges are looking for, may not exactly stretch the unexpected or &#8220;the hack&#8221; in the data.</p>
  <p>Fortunately there was plenty of latitude for exploring things laterally. The most interesting dataset was listing the chemicals and drugs each practice spent money on &#8211; but I couldn&#8217;t find much to do with it.   What caught my eye was the dataset listing the names of the doctors surgeries, practices, medical centres. If I think about my neighbourhood I can pass about half a dozen doctors in a very small area. Leeds is well covered (or perhaps just my area is!) . I was reminded of James Joyce&#8217;s quote about being unable to cross Dublin without passing a pub. Perhaps the same can be said for Leeds and doctors!  The names of the surgeries were also interesting. Names such as:</p>
  <blockquote>
  <div id="file-gistfile1-txt-LC31">Chapeloak Surgery</div>
  <div id="file-gistfile1-txt-LC32">The Avenue Surgery</div>
  <div id="file-gistfile1-txt-LC33">Dr Ca Hicks&#8217; Practice</div>
  <div>The Dekeyser Group Practice<br />
  The Highfield Medical Centre<br />
  Chapeltown Family Surgery</div>
  </blockquote>
  <p>Wonder if the more &#8220;leafy&#8221; the name, the more &#8220;leafy&#8221; the neighbourhood it was in? Perhaps the more grandiose sounding practices had more patients? Perhaps the smaller sounding ones had better patient satisfaction reviews?</p>
  <p>At the venue, it appeared that I was the only one to be using Linux on the desktop and so the wifi did not work &#8211; so I had a bit over one hour to put something together. Decided to go with the concept of &#8220;Leeds is covered&#8221; and wanted something showing the labels of the practices over the areas where they were. Filling out the map, so to speak.  The hack was called &#8220;Tim&#8217;s One Hour Data Challenge&#8221; and here is the end result:</p>

  								<content:encoded><![CDATA[<p>Last week I journeyed down on the train to Nottingham to go to WhereCampUK  &#8211; an unconference for all things &#8220;geo&#8221; &#8211;  but it was only a few months since the similarly named <a href="https://thinkwhere.wordpress.com/2009/12/11/wherecampeu-is-a-go-march-12-13-london/">WhereCampEU</a> of (which I never actually wrote something about) down in London.  Before I share some of the best bits, here&#8217;s some of the similarities and differences.</p>
  <p>* Less international folks</p>
  <p>* Less big geo personalities and keynotes</p>
  <p>* More OSM</p>
  <p>* No T-Shirts</p>
  <p>* More beer &#8211; we drank a large pub dry, literally. The next day, the landlord swore at me for pissing off their regulars.</p>
  <p>* More cake</p>
  <p>* Cheaper and quicker to run, setup and organise.</p>
  <p>For more pointers in how to run an unconference, check out <a href="http://blog.stevecoast.com/">Steve Coast</a>&#8216;s <a href="http://blog.stevecoast.com/how-i-ran-a-successful-unconference-in-6-hour">latest post</a>, where he writes about what he did for Wherecamp in Denver.  <a href="http://blog.stevecoast.com/how-i-ran-a-successful-unconference-in-6-hour">How I ran a successful unconference in 6 hours and you can too</a>.</p>
  <p>Overall, the event was great.</p>
  <p>I ran two sessions. The main one was &#8220;<a href="http://www.slideshare.net/chippy/psychogeography-at-geekup-leeds">What is Psychogeography</a>&#8220;. The best part of this was sending all participants out with directions in twos and threes, for 10 mins before lunch. They had directions such as &#8220;left left right&#8221;, &#8220;follow someone&#8221;, &#8220;ask where the centre is, follow that direction, ask again&#8221;, &#8220;find hidden portals&#8221;, &#8220;find fairies&#8221;, &#8220;hear something, take a photo&#8221;.</p>
  <p>I also quickly slotted in the <a href="http://maps.nypl.org">NYPL Warper</a> presentation, and included this slide. You get 20 points if you know what this refers to!</p>
  <p><a href="https://thinkwhere.files.wordpress.com/2010/11/benkler-hah.jpg"><img data-attachment-id="494" data-permalink="https://thinkwhere.wordpress.com/2010/11/25/wherecampuk-2010-recap/benkler-hah/#main" data-orig-file="https://thinkwhere.files.wordpress.com/2010/11/benkler-hah.jpg" data-orig-size="635,552" data-comments-opened="1" data-image-meta="{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;}" data-image-title="benkler-hah" data-image-description="" data-medium-file="https://thinkwhere.files.wordpress.com/2010/11/benkler-hah.jpg?w=300" data-large-file="https://thinkwhere.files.wordpress.com/2010/11/benkler-hah.jpg?w=635" class="alignnone size-medium wp-image-494" title="benkler-hah" src="https://thinkwhere.files.wordpress.com/2010/11/benkler-hah.jpg?w=300&#038;h=260" alt="" width="300" height="260" srcset="https://thinkwhere.files.wordpress.com/2010/11/benkler-hah.jpg?w=300&amp;h=260 300w, https://thinkwhere.files.wordpress.com/2010/11/benkler-hah.jpg?w=598&amp;h=520 598w, https://thinkwhere.files.wordpress.com/2010/11/benkler-hah.jpg?w=150&amp;h=130 150w" sizes="(max-width: 300px) 100vw, 300px" /></a></p>
  <p>I also mentioned the words &#8220;neogeography&#8221; for the first time in the conference, and that was at 3:30pm, which says quite a bit about the use of the term.</p>
  <p>Talks I liked were:</p>
  <p>* Vernacular Geography &amp; Informal Placenames</p>
  <p>* Geo Games</p>
  <p>* Education and mobile maps</p>
  <p>* Augmented Reality roundup</p>
  <p>* How streets get names</p>
  <p>* Peoples Collection Wales</p>
  <p>* Haptic Navigation</p>
  <p>* OSM Talks including &#8211; Potlatch 2</p>
  <p>* Gregory Mahler&#8217;s &#8211; I&#8217;m a Psycho Mapper!</p>
  <p>* OSGEO</p>
  <p>﻿</p>

  <pre>http://whoots.mapwarper.net/tms/!/!/!/2013/http://warper.geothings.
  net/maps/wms/2013</pre>
  <p>viewing it in Potlatch, the OpenStreetMap editor:</p>
  <div><span style="font-family:Arial, Helvetica, sans-serif;line-height:normal;font-size:small;"></p>
  <pre><a href="http://www.openstreetmap.org/edit?lat=40.73658&amp;lon=-73.87108&amp;zoom=17&amp;tileurl=http://whoots.mapwarper.net:80/tms/!/!/!/870/http://maps.nypl.org/warper/layers/wms/870"><span style="color:#000000;">http://www.openstreetmap.org/edit?lat=40.73658&amp;lon=-73.87108&amp;zoom=17
  &amp;tileurl=http://whoots.mapwarper.net:80/tms/!/!/!/870/http://maps.nypl.org/warper/layers/wms/870</span></a></pre>
  <p></span></div>
  <div>
  <p>Using a mapserver WMS request, with one layer:</p>
  <p><span style="font-family:Arial, Helvetica, sans-serif;line-height:normal;font-size:small;"> </span></p>
  <pre><a href="http://hypercube.telascience.org/cgi-bin/mapserv?map=/home/ortelius/haiti/haiti.map&amp;request=getMap&amp;service=wms&amp;version=1.1.1&amp;format=image/jpeg&amp;srs=epsg:4326&amp;exceptions=application/vnd.ogc.se_inimage&amp;layers=HAITI&amp;"><span style="color:#000000;">http://hypercube.telascience.org/cgi-bin/mapserv?map=/home/ortelius/
  haiti/haiti.map&amp;request=getMap&amp;service=wms&amp;version=1.1.1&amp;format=image/jpeg
  &amp;srs=epsg:4326&amp;exceptions=application/vnd.ogc.se_inimage&amp;layers=HAITI&amp;</span></a></pre>
  </div>
  <p>Goes to:</p>
  <div><span style="font-family:Arial, Helvetica, sans-serif;line-height:normal;font-size:small;"></p>
  <pre><a href="http://whoots.mapwarper.net:80/tms/!/!/!/HAITI/http://hypercube.telascience.org/cgi-bin/mapserv?map=/home/ortelius/haiti/haiti.map"><span style="color:#000000;">http://whoots.mapwarper.net/tms/!/!/!/HAITI/http://hypercube.telascience.org/cgi-bin/
  mapserv?map=/home/ortelius/haiti/haiti.map</span></a></pre>
  <p></span></div>
  <p>Caveats:</p>
  <p>Its&#8217;s quite simple, does not do any caching, it just redirects a tile url to an equivalent WMS request. It would only work with WMS servers that accept EPSG:900913 projections, and at the moment, it outputs OSM / Google Tile scheme, not a proper TMS tile scheme.</p>
  <p>It&#8217;s written in Ruby with the Sinatra micro web application framework. The code is available on GitHub too. <a href="http://github.com/timwaters/whoots">http://github.com/timwaters/whoots</a></p>

  <p>A group of volunteers from around the North of England on Saturday 15th May 2010, will attempt to map the entire North Yorkshire town, from every street, bridge, footpath and chip shop &#8211; in order to create a free and open map of the town. All welcome, no experience or technology required!</p>

  <p>The Association for Geographic Informations Northern Group and the OpenStreetMap Foundation are running a mapping party &#8211; a cross between an informal fieldtrip and a hands on workshop. OpenStreetMap is the wikipedia of maps &#8211; it&#8217;s open, free and anyone can edit and contribute.</p>
  <p>Organiser Tim Waters said: “OSM aims to create free geographic data, like street maps, that can be used by anyone, anywhere, and over the Saturday we aim to have a complete map of the streets of Settle and many other features in the town.”</p>
  <p>With the announcement of the Ordnance Survey releasing a lot of mid scale mapping data for free, the chances of having a top notch detailed map is greater than ever. By making a free and open map, anyone can edit and correct details, making sure the map stays up to date and relevant. It&#8217;s also free to copy and change and distribute, which is impossible to do with almost every other map.</p>
  <p>Anyone and everyone is welcome to attend, families and children are also welcome! No previous experience needed, and no GPS units needed either. GPS units will be available for people to borrow, but people can contribute a lot by using a pen and paper. It&#8217;s an open organisation with no membership requirements.</p>
  <p>People will start assembling at 10 &#8211; 10:30 a.m at Ye Olde Naked Man cafe in Settle&#8217;s central Market Place, and spend the morning mapping the area. Then they will come back and have some lunch, meeting at 1pm at Thirteen Cafe Bar and either head out again to fill in the gaps, or start editing their notes into the map system. The day comes to an end around half 3pm to 5pm, where volunteers recap on the days mapping, and have a natter over a pint of beer</p>

About the tools, services and people that surround the project. There were two talks, an OSM talk and a <a href="http://www.mapaction.org/">MapAction</a> talk. We had a good turn out.</p>

  <p>It touched upon the new Ordnance Survey OpenData and it&#8217;s impact on OSM, and how we may change the way map in the UK, and then I talked about Haiti too &#8211; how what we did &#8220;changed disaster response forever&#8221; &#8211; but only briefly as Anne-Marie Frankland from MapAction gave a great presentation about her work in Haiti, she was one of the first to deploy to the area. Really astonishing and inspiring work they did over there. Hope to be able to see those slides later.</p>
  <p>In case you were wondering, MapAction send volunteers out at the very early days of a crisis to provide mapping support and services to responders. <a href="http://www.mapaction.org/deployments/depldetail/192.html">During Haiti</a> they produced maps, installed data on GPS devices, trained search and rescue teams how to use them, produced search and rescue sector maps, locational awareness maps, helped identify locations for camps, and a whole host of other things, with not much sleep.</p>

  how the map in Scotland is looking at the start of 2019. Hopefully this will be 
  a series of posts over the next few weeks looking at different aspects of the map.&lt;/p&gt;

  &lt;p&gt;I've been organised enough to download the Scotland extract on the 1st January.
  I also have a set of data up to the 30th September 2015, so I can look at 
  progress over the last 2 and quarter years.&lt;/p&gt;

  &lt;p&gt;First up is Highways:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2019-01-24-sotm1/scotland_highways_grey.png&quot; alt=&quot;&quot; /&gt;&lt;/p&gt;

      &lt;/tr&gt;
    &lt;/tbody&gt;
  &lt;/table&gt;

  &lt;p&gt;To start with, lets look at the roads. As has been the case for a number of years
  mapping the main road network in Scotland was completed a number of years ago,
  and the recent changes have been related to some big construction projects such
  as the Queensferry Crossing, M8 Upgrades and the Queensferry Crossing&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2019-01-24-sotm1/scotland_motorways_2015vs2018.png&quot; alt=&quot;&quot; /&gt;
  &lt;em&gt;All motorways in Scotland, red shows the new Motorways&lt;/em&gt;&lt;/p&gt;

  &lt;p&gt;The only road type showing a drop in length is unclassified. This is largely down
  to improvements in the classifications of roads, in particular to
  &lt;a href=&quot;https://wiki.openstreetmap.org/wiki/Tag:highway=tertiary?uselang=en-GB&quot;&gt;tertiary&lt;/a&gt;&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2019-01-24-sotm1/scotland_service_roads.png&quot; alt=&quot;&quot; /&gt;
  &lt;em&gt;Service Roads in Scotland&lt;/em&gt;&lt;/p&gt;

  &lt;p&gt;We've also seen a big increase in Service roads, it's worth noting that 
  a number of these have been added by Amazon Logistics - they seem to be adding
  just the last little bit connecting roads to buildings, the service road from 
  road to the house or the office. These edits definitly have been rocky at times, such as 
  the &lt;a href=&quot;https://www.openstreetmap.org/changeset/61074110&quot;&gt;removal of a car park, just mapped&lt;/a&gt;
  based on out of imagery. In general I've very happy to see commerical edits, but
  as this shows new mappers need to be properly trained on how to asses the general
  state of the map especially before removing things.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2019-01-24-sotm1/scotland_paths_tracks_cycleways.png&quot; alt=&quot;&quot; /&gt;
  &lt;em&gt;Paths Tracks and Cycleways - New highways are shown in red&lt;/em&gt;&lt;/p&gt;

  &lt;p&gt;I've very pleased to see big increases, in the mapping of tracks and
  paths as well as the increase in cycleways although I think these are largely 
  fine tuning of tagging of paths. Hopefully it won't be long until we have full 
  coverage of all paths and tracks and these will be much more stable.&lt;/p&gt;

  &lt;p&gt;Finally we have the long tail of tags, of these highway=road, which is 
  really a placeholder and shouldn't be used still has far too many entries so for
  the moment, I've made a list of these to work through - &lt;a href=&quot;https://github.com/osm-scotland/scotland-issues/issues/4&quot;&gt;https://github.com/osm-scotland/scotland-issues/issues/4)&lt;/a&gt;
  if anyone wants to help then jump in, let me know if you need permission 
  for the github link.&lt;/p&gt;

  &lt;p&gt;The same thing applies to highway=no; These have mostly been used where a highway
  has been removed. This is useful as it signals to remote mappers (such as the 
  amazon logistics folks above) that the road has been removed. However once the 
  imagery updates having these no longer makes sense. In case any one wants to 
  look at these, I've made a list at:

  between Helensburgh in the West from where John Muir setoff to the United States where he inspired the 
  conservation movement and the creation of it's national parks. To Dunbar on the East Coast where he was born
  and grew uo.&lt;/p&gt;

  &lt;p&gt;We've covered most of the route in OpenStreetMap for while. But until recently we've had a tiny, gap missing. I was trying
  to figure out getting over to do it when I saw:&lt;/p&gt;

  &lt;blockquote class=&quot;twitter-tweet&quot; data-partner=&quot;tweetdeck&quot;&gt;&lt;p&gt;&lt;a href=&quot;https://twitter.com/chrisfl&quot;&gt;@chrisfl&lt;/a&gt; &lt;a href=&quot;https://twitter.com/fozy81&quot;&gt;@fozy81&lt;/a&gt;  to map that gap took 2 trains 1 to Helensburgh a 9 miles walk then train from Balloch. Great day &lt;a href=&quot;http://t.co/5GcJ2jp5At&quot;&gt;pic.twitter.com/5GcJ2jp5At&lt;/a&gt;&lt;/p&gt;&amp;mdash; Martin McMahon (@mazscot) &lt;a href=&quot;https://twitter.com/mazscot/statuses/469358588750999552&quot;&gt;May 22, 2014&lt;/a&gt;&lt;/blockquote&gt;
  &lt;script async=&quot;&quot; src=&quot;//platform.twitter.com/widgets.js&quot; charset=&quot;utf-8&quot;&gt;&lt;/script&gt;

  &lt;p&gt;So with some not insignificant effort, we now have the complete route mapped, these can easily be seen by looking at a 
  raw view of either the walking route http://www.openstreetmap.org/relation/49215
  or the cycling route http://www.openstreetmap.org/relation/3619145 on OpenStreetMap, but where OSM comes into it's own 
  is the ability to actually do things with the data, so to kick things off I've created a set of GPX files of the route.&lt;/p&gt;

  &lt;p&gt;These contain the full walking or cycling route and are suitable to be loaded into your GPS or phone app as aids to navigating the 
  route.&lt;/p&gt;

    &lt;/li&gt;
  &lt;/ul&gt;

  &lt;p&gt;Map wise, as always I'm disapointed to see the otherwise very nice John Muir Way website using google maps rather than an OpenStreetMap 
  based map:&lt;/p&gt;

  &lt;div id=&quot;map&quot; style=&quot;width:100%; height:300px; border:0px;&quot;&gt;

  &lt;/div&gt;

  &lt;p&gt;There are also tools such as Relation Analyser - http://ra.osmsurround.org/analyzeRelation?relationId=3619145 
  Interestingly this shows cycling distance as 206km and the walking distance as 213km while the route is offically 215 km (I guess they rounded up)&lt;/p&gt;

  &lt;script type=&quot;text/javascript&quot;&gt;
  // initialize the map on the &quot;map&quot; div with a given center and zoom
      var map = new L.Map('map', {
        center: new L.LatLng(56.01319,-4.68119),

  coming at the weekend.  I thought that it was about time that I start this
  series of posts that I've been planning for a while, so hopefully here is part
  1 Android applications for collecting data.&lt;/p&gt;

  &lt;p&gt;## Tracking, OSM Tracker #&lt;/p&gt;

  &lt;p&gt;One of the key apps, is something that can track where you are, providing a
  record of where you've been and allowing you to upload it to the OpenStreetMap
  website. OSM's heritage is built around collecting data using a GPS, and it still 
  remains a powerfull way of mapping an area without requiring other sources. And 
  we actually are all carrying a GPS device around with us in our pocket it is
  very easy to do.&lt;/p&gt;

  &lt;p&gt;I use &lt;a href=&quot;https://play.google.com/store/apps/details?id=me.guillaumin.android.osmtracker&quot;&gt;OSM Tracker&lt;/a&gt;
  it's a simple app, and does it well, as well as recording a GPS trail, it also 
  allows you to take pictures, and display the track on a map.&lt;/p&gt;

  &lt;p&gt;Use is really simple, start a new track:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2014-03-23-android-apps-for-mapping/OSMTracker_1.png&quot; alt=&quot;&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;Once it is running, it displays the currently GPS Position, shortcuts for taking a picture, and noting various features:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2014-03-23-android-apps-for-mapping/OSMTracker_2.png&quot; alt=&quot;&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;It is also possible to view the track on a map, this is really useful for checking the current area mapped, and seeing where you've been:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2014-03-23-android-apps-for-mapping/OSMTracker_3.png&quot; alt=&quot;&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;Finally, it's possible to tag save and upload the track:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2014-03-23-android-apps-for-mapping/OSMTracker_4.png&quot; alt=&quot;&quot; /&gt;&lt;/p&gt;

  &lt;h2 id=&quot;editing-vespucci&quot;&gt;Editing, Vespucci&lt;/h2&gt;

  &lt;p&gt;Editing is generally done as after mapping on a computer, but it can be really helpful to be able to make some changes from your phone, especially once you're more
  experienced, I would recommend using &lt;a href=&quot;https://play.google.com/store/apps/details?id=de.blau.android&quot;&gt;Vespucci&lt;/a&gt;, 
  Vespucci is getting better and better all the time, and does a really good job editing using the touch interface. This isn't necessary a beginners tool, 
  but a good tool that continues to improve that's definitly worth looking at.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2014-03-23-android-apps-for-mapping/vespucci_1.png&quot; alt=&quot;&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;When you click on the map, it allows you to choose what item you wish to edit, which is a good solution to the problem of never being able to select accurately enough with
  your finger. Geometries can then we tweaked as neccessary.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2014-03-23-android-apps-for-mapping/vespucci_3.png&quot; alt=&quot;&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;Although I tend to use it to make small changes such as editing tags rather than big edits, it's a powerfull tool that only gets better.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2014-03-23-android-apps-for-mapping/vespucci_2.png&quot; alt=&quot;&quot; /&gt;&lt;/p&gt;

  &lt;h2 id=&quot;data-gathering&quot;&gt;Data Gathering&lt;/h2&gt;

  &lt;h3 id=&quot;accessibilty-wheelmap&quot;&gt;Accessibilty, Wheelmap&lt;/h3&gt;

  &lt;p&gt;&lt;a href=&quot;https://play.google.com/store/apps/details?id=org.wheelmap.android.online&quot;&gt;Wheelmap&lt;/a&gt; is a great example of a simple data gathering app.
  The wheelchair app collects accessibilty information as well as some simple addressing information to be displayed on the &lt;a href=&quot;http://wheelmap.org/en/&quot;&gt;Wheelmap Site&lt;/a&gt;&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2014-03-23-android-apps-for-mapping/wheelmap_1.png&quot; alt=&quot;&quot; /&gt;

  &lt;h3 id=&quot;addressing-keypadmapper&quot;&gt;Addressing, Keypadmapper&lt;/h3&gt;

  &lt;p&gt;As we have mapped a significant proportion of the road network, there is now a big push to collect addressing data
  &lt;a href=&quot;https://play.google.com/store/apps/details?id=de.enaikoon.android.keypadmapper3&quot;&gt;Keypadmapper&lt;/a&gt; is a simple app to collect addressing data as 
  you move down the road simply enter the numbers as you pass them. Later the address points can be loaded into &lt;a href=&quot;https://josm.openstreetmap.de/&quot;&gt;JOSM&lt;/a&gt; for adding into
  OpenStreetMap.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2014-03-23-android-apps-for-mapping/keypadmapper.png&quot; alt=&quot;&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;So a quick summary of the apps:&lt;/p&gt;

  &lt;p&gt;I had the plesure of doing a talk for the &lt;a href=&quot;http://www.rotary-ribi.org/clubs/homepage.php?ClubID=1868&quot;&gt;Rotary Club of Esk Valley &lt;/a&gt;this Tuesday, the talk was based on the &lt;a href=&quot;http://www.chrisfleming.org/osm/state-of-the-map-scotland-2013-the-state-of-scotland/&quot;&gt;talk I gave at SoTM Scotland,&lt;/a&gt;  with some of the more detailed information removed and some more introductory material added. So this posting is to cover some of the new stuff I covered or at least meant to cover.&lt;/p&gt;

  &lt;p&gt;I started with an introduction to &lt;a href=&quot;http://www.openstreetmap.org/&quot;&gt;OpenStreetMap&lt;/a&gt; briefly touching on the &lt;a href=&quot;http://opendatacommons.org/licenses/odbl/summary/&quot;&gt;licencing terms&lt;/a&gt; and then lot of examples, such as &lt;a href=&quot;http://www.cyclestreets.net/&quot;&gt;cyclestreets &lt;/a&gt;for cycle planning, &lt;a href=&quot;http://blog.foursquare.com/2012/02/29/foursquare-is-joining-the-openstreetmap-movement-say-hi-to-pretty-new-maps/&quot;&gt;foursquare&lt;/a&gt;, &lt;a href=&quot;http://openpistemap.org/?lat=56.8831&amp;amp;lon=-3.4034&amp;amp;zoom=14&amp;amp;layers=BTTTT&quot;&gt;ski maps&lt;/a&gt;, and not forgetting the &lt;a href=&quot;http://osmalba.org/&quot;&gt;Gaelic Map&lt;/a&gt;.&lt;/p&gt;

  &lt;p&gt;I then moved on to talk about &lt;a href=&quot;http://hot.openstreetmap.org/&quot;&gt;HOT&lt;/a&gt;'s Humanitarian Work, borrowing lots of material from a &lt;a href=&quot;http://www.averillpark.net/OSM/HOT/&quot;&gt;previous HOT presentation&lt;/a&gt;.&lt;/p&gt;

  &lt;p&gt;After some talk about quality and contributors, I showed how to create an account and some slides on starting to use potlatch. I moved on to talk about phone apps. The full list for &lt;a href=&quot;http://wiki.openstreetmap.org/wiki/Android&quot;&gt;Android&lt;/a&gt; and &lt;a href=&quot;http://wiki.openstreetmap.org/wiki/Apple_iOS&quot;&gt;iOS&lt;/a&gt; on the OSM wiki is quite intimidating so I wanted to give some specific suggestions to help get people started.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2013-01-18-osm-talk-for-esk-valley-rotary-club/jan_2013_talk.058.jpg&quot; alt=&quot;wheelmap.org screenshot&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;Simplest of all and working on both platforms is &lt;a href=&quot;http://wheelmap.org/&quot;&gt;wheelmap.org&lt;/a&gt;Which provides a really simple interface to allow users to add accessibility information to existing places in OSM.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2013-01-18-osm-talk-for-esk-valley-rotary-club/jan_2013_talk.059.jpg&quot; alt=&quot;Pushpin App Screenshot&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;To add or edit POI's on iOS there really is a simple choice, &lt;a href=&quot;http://pushpinosm.org/&quot;&gt;Pushpin&lt;/a&gt; a really nice simple well though out interface.
  &lt;img src=&quot;/post-assets/2013-01-18-osm-talk-for-esk-valley-rotary-club/jan_2013_talk.060.jpg&quot; alt=&quot;Vespucci Screenshot&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;On Android, I recommend  &lt;a href=&quot;https://play.google.com/store/apps/details?id=de.blau.android&quot;&gt;Vespucci&lt;/a&gt;, it's not as simple as pushpin but does allow a lot more to be edited on the go.&lt;/p&gt;

  &lt;p&gt;For more advanced mapping users may want to &lt;a href=&quot;http://wiki.openstreetmap.org/wiki/Beginners_Guide_1.2&quot;&gt;collect tracks&lt;/a&gt;. For Android I had lots of apps to choose from:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2013-01-18-osm-talk-for-esk-valley-rotary-club/jan_2013_talk.061.jpg&quot; alt=&quot;OSM Tracker App&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;and I would recommend&lt;a href=&quot;https://play.google.com/store/apps/details?id=me.guillaumin.android.osmtracker&quot;&gt; OSMtracker&lt;/a&gt;, it collects the GPS track and also allows some POI's to be noted on the go.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2013-01-18-osm-talk-for-esk-valley-rotary-club/jan_2013_talk.062.jpg&quot; alt=&quot;OSM4iPhone Screenshot&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;The choice was much more limited on iOS and in the end I couldn't quickly find a free app, so I find myself recommending &lt;a href=&quot;https://itunes.apple.com/gb/app/osmtrack/id295625255?mt=8&quot;&gt;OSMTrack&lt;/a&gt; which costs a mere 69p as is ideal as it can upload directly into OSM as well as supporting offline data.&lt;/p&gt;

  &lt;p&gt;and that was it, I had already talked far too long and so it was time to finsh up and go to questions.&lt;/p&gt;

  &lt;p&gt;We had some good questions, about using &lt;a href=&quot;http://wiki.openstreetmap.org/wiki/Education&quot;&gt;OSM for teaching&lt;/a&gt;, one of the users had already installed wheelmap and was adding information.&lt;/p&gt;

  &lt;p&gt;Someone also asked if we had Kevock Road, so I took a deep breath and entered it into the search box.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2013-01-18-osm-talk-for-esk-valley-rotary-club/kevlock_road.png&quot; alt=&quot;&quot; /&gt;
  and I was very happy to find the road was there and we had lots of details around it.&lt;/p&gt;

  &lt;p&gt;A big thanks to the Club for inviting me out and being such a good audience.&lt;/p&gt;</content><author><name>Chris Fleming</name></author><summary type="html">I had the plesure of doing a talk for the Rotary Club of Esk Valley this Tuesday, the talk was based on the talk I gave at SoTM Scotland,  with some of the more detailed information removed and some more introductory material added.

After some talk about quality and contributors, I showed how to create an account and some slides on starting to use potlatch. I moved on to talk about phone apps. The full list for Android and iOS on the OSM wiki is quite intimidating so I wanted to give some specific suggestions to help get people started. Simplest of all and working on both platforms is wheelmap.orgWhich provides a really simple interface to allow users to add accessibility information to existing places in OSM. To add or edit POI's on iOS there really is a simple choice, Pushpin a really nice simple well though out interface. On Android, I recommend  Vespucci, it's not as simple as pushpin but does allow a lot more to be edited on the go. For more advanced mapping users may want to collect tracks. For Android I had lots of apps to choose from: and I would recommend OSMtracker, it collects the GPS track and also allows some POI's to be noted on the go. The choice was much more limited on iOS and in the end I couldn't quickly find a free app, so I find myself recommending OSMTrack which costs a mere 69p as is ideal as it can upload directly into OSM as well as supporting offline data. and that was it, I had already talked far too long and so it was time to finsh up and go to questions. We had some good questions, about using OSM for teaching, one of the users had already installed wheelmap and was adding information. Someone also asked if we had Kevock Road, so I took a deep breath and entered it into the search box. and I was very happy to find the road was there and we had lots of details around it. A big thanks to the Club for inviting me out and being such a good audience.</summary></entry><entry><title type="html">State of the Map Scotland 2012 - The State of Scotland</title><link href="http://chrisfleming.org//openstreetmap/state-of-the-map-scotland-2012-the-state-of-scotland" rel="alternate" type="text/html" title="State of the Map Scotland 2012 - The State of Scotland" /><published>2012-10-25T12:37:41+01:00</published><updated>2012-10-25T12:37:41+01:00</updated><id>http://chrisfleming.org//openstreetmap/state-of-the-map-scotland-2012-the-state-of-scotland</id><content type="html" xml:base="http://chrisfleming.org//openstreetmap/state-of-the-map-scotland-2012-the-state-of-scotland">&lt;p&gt;Once again, this year, I had the pleasure of presenting the opening at our now, not so little State of the Map Scotland Conference, which was held at &lt;a href=&quot;http://inspace.mediascot.org/&quot;&gt;Inspace&lt;/a&gt; on the 19th and 20th October 2012.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.001.jpg&quot; alt=&quot;The State of Scotland 2012, State of the Map Scotland, Edinburgh, @chrisfl, #sotmscot&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;When I started to write this talk, I wasn't sure where it was going to end up, I found it interesting and I hope that you do to.&lt;/p&gt;

  &lt;p&gt;For me one of the most exciting trends, over the last year is seeing OpenStreetMap appearing invarious places:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.002.jpg&quot; alt=&quot;2012 started as the year of switch2osm&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;(photo: &lt;a href=&quot;http://www.flickr.com/photos/xerones/131963343/&quot;&gt;http://www.flickr.com/photos/xerones/131963343/&lt;/a&gt;)&lt;/p&gt;

  &lt;p&gt;the &lt;a href=&quot;http://switch2osm.org/&quot;&gt;switch2osm&lt;/a&gt;, 2012 started with an announcement by &lt;a href=&quot;http://www.nestoria.co.uk/&quot;&gt;nestoria&lt;/a&gt; that they were moving over OSM.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.003.jpg&quot; alt=&quot;nestoria website&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;&lt;a href=&quot;http://blog.nestoria.co.uk/tag/openstreetmap&quot;&gt;Triggered  by the ever improving quality of OSM&lt;/a&gt;, as well as google looking at charging, it was great to see this long term support switch to using our map.&lt;/p&gt;

  &lt;p&gt;Another example is is &lt;a href=&quot;https://foursquare.com/&quot;&gt;foursquare. &lt;/a&gt;&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.004.jpg&quot; alt=&quot;foursquare website&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;I was amazed when I opened the site at the prominence given to the map on the foursquare homepage. This shouldn't be a surprise, given the nature of the site but I don't think  a google map would have  made the landing page here.&lt;/p&gt;

  &lt;p&gt;It was also interesting to watch the foursquare community, I think overall OSM has gained visibility and exposure from this change (citation needed)&lt;/p&gt;

  &lt;p&gt;Flickr has  &lt;a href=&quot;http://code.flickr.com/blog/2012/07/11/designing-an-osm-map-style/&quot;&gt;continued to have some OSM maps&lt;/a&gt; and improve those maps, despite a new deal yahoo has to switch to Nokia maps, has &lt;a href=&quot;http://code.flickr.com/blog/2012/07/11/designing-an-osm-map-style/&quot;&gt;continued to have some OSM maps. &lt;/a&gt;&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.005.jpg&quot; alt=&quot;iflickr map, showing Beijing&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;I would love to see  OSM as a layer across flickr's maps, the Nokia maps are a big improvement but are still aimed at car drivers and so still miss lots of places where photo's might be taken. Hopefully we will see  more OSM on flickr in the future.&lt;/p&gt;

  &lt;p&gt;Finally as a more personal example of a switch2osm. I switched my parents &lt;a href=&quot;http://www.bullfarmoast.co.uk/&quot;&gt;B&amp;amp;B in Kent &lt;/a&gt; over to use OSM.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.006.jpg&quot; alt=&quot;B&amp;amp;B at Bull Farm Oast, map page&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;This change was a little overdue, but for me is a milestone on my journey with OSM, I first discovered OpenStreetMap when I was trying to locate local attractions when I first added a google map to this site, back around 2006.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.007.jpg&quot; alt=&quot;Sissinghurst Castle information page.&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;I wasn't surprised by the detail on the &lt;a href=&quot;http://www.bullfarmoast.co.uk/attractions/Sissinghurst_Castle&quot;&gt;Sissinghurst page&lt;/a&gt;, as I mapped this myself.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.008.jpg&quot; alt=&quot;Bodiam Castle information page&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;but in fact zoomed in, almost every page such as this one for &lt;a href=&quot;http://www.bullfarmoast.co.uk/attractions/Bodiam_Castle&quot;&gt;Bodiam Castle&lt;/a&gt; has lots of the little bits of detail, such as the moat, ticket office and car park (not shown here).&lt;/p&gt;

  &lt;p&gt;A lot of this is now possible, because more and more companies are starting to provide services around OSM. As I said last year:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.009.jpg&quot; alt=&quot;OSM Database Server&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;Rightly or wrongly &lt;strong&gt;OSM is currently setup largely as a data provider - &lt;/strong&gt;so it's really great to see these other &quot;consumer&quot; facing options and websites appear as the more people see OSM the better our data becomes even if only a ting percentage of these can be converted into mappers. Obviously better information and simpler tools may help to lower the entry barrier in the future.&lt;/p&gt;

  &lt;p&gt;The biggest recent impact has been from &lt;a href=&quot;http://mapbox.com/&quot;&gt;mapbox:&lt;/a&gt;&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.010.jpg&quot; alt=&quot;Mapbox website&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;Also a big shout out to the &lt;a href=&quot;http://maps.stamen.com/&quot;&gt;Stamen&lt;/a&gt; map styles and tiles:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.011.jpg&quot; alt=&quot;Black and White map of Glasgow Center&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;such as the toner style above or the acclaimed watercolour style that I used on the first slide.&lt;/p&gt;

  &lt;p&gt;While we're on styles, we can't ignore the continuous improvement's to the OSM &quot;house&quot; style:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.012.jpg&quot; alt=&quot;OpenStreetMap - showing Aberdeen&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;The cycle map style:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.013.jpg&quot; alt=&quot;OpenStreetMap, cyclemap style, low zoom showing lots of scotland&quot; /&gt;]&lt;/p&gt;

  &lt;p&gt;public transport style:
  &lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.014.jpg&quot; alt=&quot;OSM Website, public transport style, centered on Glasgow.&quot; /&gt;]&lt;/p&gt;

  &lt;p&gt;and mapquest style
  &lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.015.jpg&quot; alt=&quot;Openstreetmap website, showing mapquest style centered on Glasgow&quot; /&gt;]&lt;/p&gt;

  &lt;p&gt;again &lt;a href=&quot;http://open.mapquest.co.uk/&quot;&gt;mapquest open&lt;/a&gt; provides a great example of a complete web mapping site, with search and routing. So provides a potential OSM powered  google maps replacement.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.016.jpg&quot; alt=&quot;So What about the streets&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;So last year we did a comparison between the OS Locator dataset and OSM using the ITO Analysis tool, by region. I've added this years data into the table.&lt;/p&gt;

  &lt;table&gt;
    &lt;thead&gt;
      &lt;tr&gt;
        &lt;th&gt;Place&lt;/th&gt;
        &lt;th&gt;2012&lt;/th&gt;
        &lt;th&gt;OS Locator&lt;/th&gt;
        &lt;th&gt;2012&lt;/th&gt;
        &lt;th&gt;“Missing”&lt;/th&gt;
        &lt;th&gt;2012 Roads&lt;/th&gt;
        &lt;th&gt;11 to 12 change&lt;/th&gt;
      &lt;/tr&gt;
      &lt;tr&gt;
        &lt;th&gt; &lt;/th&gt;
        &lt;th&gt;position&lt;/th&gt;
        &lt;th&gt; &lt;/th&gt;
        &lt;th&gt; &lt;/th&gt;
        &lt;th&gt; &lt;/th&gt;
        &lt;th&gt; &lt;/th&gt;
        &lt;th&gt; &lt;/th&gt;
      &lt;/tr&gt;
    &lt;/thead&gt;
    &lt;tbody&gt;
      &lt;tr&gt;
        &lt;td&gt;Edinburgh&lt;/td&gt;
        &lt;td&gt;4&lt;/td&gt;
        &lt;td&gt;4,760&lt;/td&gt;
        &lt;td&gt;4784&lt;/td&gt;
        &lt;td&gt;0&lt;/td&gt;
        &lt;td&gt;9&lt;/td&gt;

        &lt;td&gt;1193&lt;/td&gt;
        &lt;td&gt;0&lt;/td&gt;
        &lt;td&gt;9&lt;/td&gt;
        &lt;td&gt;100 -&amp;gt; 99.25&lt;/td&gt;
      &lt;/tr&gt;
    &lt;/tbody&gt;
    &lt;tbody&gt;
      &lt;tr&gt;

        &lt;td&gt;819&lt;/td&gt;
        &lt;td&gt;5&lt;/td&gt;
        &lt;td&gt;0&lt;/td&gt;
        &lt;td&gt;99.27 -&amp;gt; 100&lt;/td&gt;

      &lt;/tr&gt;
    &lt;/tbody&gt;
    &lt;tbody&gt;
      &lt;tr&gt;
        &lt;td&gt;Moray&lt;/td&gt;
        &lt;td&gt;29&lt;/td&gt;
        &lt;td&gt;1545&lt;/td&gt;
        &lt;td&gt;1581&lt;/td&gt;
        &lt;td&gt;366&lt;/td&gt;
        &lt;td&gt;226&lt;/td&gt;
        &lt;td&gt;75.92 -&amp;gt; 85.45&lt;/td&gt;
      &lt;/tr&gt;
    &lt;/tbody&gt;
  &lt;/table&gt;

  &lt;p&gt;The first thing that struck me as that in both Edinburgh and Midlothian the total number of roads has increased, but we've missed some so we're not longer at 100%.&lt;/p&gt;

  &lt;p&gt;There have been some fantastic, improvements Glasgow was missing 171 roads last year and these have been accounted for. Dumfries And Galloway was bottom of the list last year and it's now in 7th, as has Aberdeen City.&lt;/p&gt;

  &lt;p&gt;There are also some places such as Na H Eileanan An Iar; also known as the Outer Hebredies which are looking quite static.&lt;/p&gt;

  &lt;p&gt;So what does that all add up to?&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.019.jpg&quot; alt=&quot;2011, 4316 Roads Missing from OSM Compared to OS, Scotland was 93% Complete. In 2012, 1972 Roads Missing. Scotland 95% Complete&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;In 2011, we  were shown as having 4316 Roads that hadn't been accounted for, so 93% match.&lt;/p&gt;

  &lt;p&gt;When I looked a few days ago, we only  don't align on 1972 missing roads, or a 95% match.&lt;/p&gt;

  &lt;p&gt;So what are these missing streets? I started by looking at the 9 roads highlighted in Edinburgh.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.020.jpg&quot; alt=&quot;ITO Analysis Map, showing missing new estate road names,&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;The first stop are these Roads in &lt;a href=&quot;http://www.openstreetmap.org/?lat=55.95985&amp;amp;lon=-3.40179&amp;amp;zoom=17&amp;amp;layers=M&quot;&gt;Kirkliston&lt;/a&gt;, we seem to have one of these roads, but are missing the name, the other two roads are shown in OSM as under construction as below.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.021.jpg&quot; alt=&quot;OSM Map showing &amp;quot;missing streets&amp;quot; as roads under contruction.&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;So the conclusion is probably a draw on this one, it looks like neither OS Locator or OSM have the full picture, but a visit is needed.&lt;/p&gt;

  &lt;p&gt;The next example is around &lt;a href=&quot;http://www.openstreetmap.org/?lat=55.944719016552&amp;amp;lon=-3.36523085832596&amp;amp;zoom=17&quot;&gt;Edinburgh Airport&lt;/a&gt;&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.022.jpg&quot; alt=&quot;ITO Analysis Map, OSM shows Almond Avenue and OSM shows Almond Drive&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;OSM Shows Almond Avenue, but OS Locator Almond drive. A visit here will need to take place to confirm who is right.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.023.jpg&quot; alt=&quot;ITO Map, showing missing road&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;Again it looks like some new houses here have led to some new developments that we don't yet have.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.024.jpg&quot; alt=&quot;ITO Map, showing new estate&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;This one was quite simple the Lane and the footpath should be joined, so I fixed this myself.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.025.jpg&quot; alt=&quot;ITO Map&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;I think that this one is a new development, that needs visiting.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.026.jpg&quot; alt=&quot;ITO Map&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;Again this one in Newhaven is probably a new development, that needs visiting.&lt;/p&gt;

  &lt;p&gt;Interestingly in the few days since I gave this presentation, some of these have been fixed, by changes such as this one: &lt;a href=&quot;http://www.openstreetmap.org/browse/changeset/13611107&quot;&gt;&quot;Added missing street names from ITO in Kirkliston&quot;&lt;/a&gt; and this &quot;&lt;a href=&quot;http://www.openstreetmap.org/browse/way/187296573/history&quot;&gt;Added initial layout of new housing development in Newburgh, Edinburgh.&lt;/a&gt;&quot;. I really hope that these were done with local knowledge especially as adding the through road through Kirkliston doesn't looks like the kind of road layout that would be permitted as it would allow a rat run through a residential area.&lt;/p&gt;

  &lt;p&gt;Anyway, we have evidence that OS Locator data can't always be relied upon.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.027.jpg&quot; alt=&quot;How accurate is OS data? In Edinburgh 2.2% of names don't match, in Glasgow 1.4% of names don't match. Worst case in the UK, in King's Lynn and West Norfolkm 7.4% don't match.&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;Already in Edinburgh 2.2% of roads in Edinburgh do not match what OS Locator shows.&lt;/p&gt;

  &lt;p&gt;Glasgow, 1.4 % and looking at one of the other places at 100%, Kings's Lynn shows 7.4% out. This is really a warning, we should be using this as a datasource to help us know where to map, but this data cannot be relied upon.&lt;/p&gt;

  &lt;p&gt;Something else was causing me concern, and that was in the Outer Hebrides.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.028.jpg&quot; alt=&quot;How are we doing in Remote Places, like the Outer Hebrides&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;It also helps that I've holidayed and mapped here (or should it be the other way round) and so have lots of photos :)&lt;/p&gt;

  &lt;p&gt;There weren't many changes in 2011 of 298 roads we were missing 5 and in 2012 the total roads is 297 and we're missing 4.&lt;/p&gt;

  &lt;p&gt;So first thing, I thought that I would look at the last modification data of a selection of the objects:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.029.jpg&quot; alt=&quot;2006, 971, 2007: 10499, 2008: 2967, 2009: 7015, 2010: 61878, 2011: 8698, 2012: 26600&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;This wasn't quite what I expected, so  far this year there has been &lt;em&gt;a lot&lt;/em&gt; of activity.&lt;/p&gt;

  &lt;p&gt;And so I thought I would break down into months:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.030.jpg&quot; alt=&quot;&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;So the basic level is quite small, but with a big peak in June and July.&lt;/p&gt;

  &lt;p&gt;Looking in detail at June I saw, most of the changes:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.031.jpg&quot; alt=&quot;&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;we're made by a single user, brianboru. I was very happy to see that he had been there and  and some of the information is surveyed on the ground with lots of detailed tracing of terrain, helping to fill in the map, so I thought I would see what else this user was up to?&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.032.jpg&quot; alt=&quot;&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;So he's from Birmingham, and by the looks of things he like I holidayed and did a ton of mapping and tracing whilse on holiday.&lt;/p&gt;

  &lt;p&gt;But once I ignored the holiday based tracing binges, there is a steady background work by seumas, and looking at his page, I was again very pleased to see that he does live on the Island.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.033.jpg&quot; alt=&quot;&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;and busy doing some mapping of shops, pubs, chippies and some paths:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.034.jpg&quot; alt=&quot;&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;This was really for me the Golden Road, to be honest I didn't expect to find a local mapper living on the edge of the country, but here he is.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.035.jpg&quot; alt=&quot;&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;So how much data do we have:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.036.jpg&quot; alt=&quot;Cat - WHAT DO WE HAVE?&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;Overall the breakdown over Scotland is:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.037.jpg&quot; alt=&quot;1.2G of XML, 5 847 127 Nodes, 483 990 Ways, 5086 Relation Compared to before the license change, 5 206 480 Nodes, 451 091 Ways, 4844 Relations&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;]he uncompressed XML weighs in at 1.2G on disk, consisting of nearly 6 million nodes, nearly 500 000 ways and 5000 relations.&lt;/p&gt;

  &lt;p&gt;I also ran this against a dump from before the licence change, and we have grown significantly since then, by over 600 000 nodes, and  30 000 ways. So we are well above the numbers from before the change, and thanks to the hard work of the community in Scotland to get local mappers on board and also to mitigate against loss I don't think we had any big problems.&lt;/p&gt;

  &lt;p&gt;What's in a name?&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.0381.jpg&quot; alt=&quot;36 660 named nodes and 134 724 named ways&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;We have 36 660 named nodes and 134 724 named ways.&lt;/p&gt;

  &lt;p&gt;Place?&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.0391.jpg&quot; alt=&quot;6807 Names Places&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;6807 of these are places, from Cities down to Hamlets and localities.&lt;/p&gt;

  &lt;p&gt;So how long are the ways:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.040.jpg&quot; alt=&quot;&quot; /&gt;
  The table above lists the top 20 way types by length.&lt;/p&gt;

  &lt;p&gt;The total, motorway length in OSM shows as 827km compares well with the total motorway length in wikipedia (once I remembered that OSM will have ways for both directions)&lt;/p&gt;

  &lt;p&gt;We have 4 226km of paths, I suspefct there are a lot more in Scotland.&lt;/p&gt;

  &lt;p&gt;We're up to 1 645 km of cycleway, and additionally cycling is permitted on a further 1000km of footways and paths.&lt;/p&gt;

  &lt;p&gt;We have 53 km of steps, I wouldn't want to climb those all at once.&lt;/p&gt;

  &lt;p&gt;There is also the longtail of the list:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.041.jpg&quot; alt=&quot;&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;Somewhere we have 30m of broken bridge (not the one pictured), 10 km of racing track and 1 099m of train platforms.&lt;/p&gt;

  &lt;p&gt;Last year I asked the question.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.044.jpg&quot; alt=&quot;How do we extend the community?&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;I still don't think we have a really good answer to that question, but whatever we do, we must Tell People.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.045.jpg&quot; alt=&quot;Tell people, OSM is not like fight club, Tell your sister mother brother, Tell your friends and enemies, Show everyone you meet, Go out your way to tell strangers&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;It's the only way of improving the map.&lt;/p&gt;

When I started to write this talk, I wasn't sure where it was going to end up, I found it interesting and I hope that you do to. For me one of the most exciting trends, over the last year is seeing OpenStreetMap appearing invarious places: (photo: http://www.flickr.com/photos/xerones/131963343/) the switch2osm, 2012 started with an announcement by nestoria that they were moving over OSM. Triggered  by the ever improving quality of OSM, as well as google looking at charging, it was great to see this long term support switch to using our map. Another example is is foursquare.  I was amazed when I opened the site at the prominence given to the map on the foursquare homepage. This shouldn't be a surprise, given the nature of the site but I don't think  a google map would have  made the landing page here. It was also interesting to watch the foursquare community, I think overall OSM has gained visibility and exposure from this change (citation needed) Flickr has  continued to have some OSM maps and improve those maps, despite a new deal yahoo has to switch to Nokia maps, has continued to have some OSM maps.  I would love to see  OSM as a layer across flickr's maps, the Nokia maps are a big improvement but are still aimed at car drivers and so still miss lots of places where photo's might be taken. Hopefully we will see  more OSM on flickr in the future. Finally as a more personal example of a switch2osm. I switched my parents B&amp;amp;B in Kent  over to use OSM. This change was a little overdue, but for me is a milestone on my journey with OSM, I first discovered OpenStreetMap when I was trying to locate local attractions when I first added a google map to this site, back around 2006. I wasn't surprised by the detail on the Sissinghurst page, as I mapped this myself. but in fact zoomed in, almost every page such as this one for Bodiam Castle has lots of the little bits of detail, such as the moat, ticket office and car park (not shown here). A lot of this is now possible, because more and more companies are starting to provide services around OSM. As I said last year: Rightly or wrongly OSM is currently setup largely as a data provider - so it's really great to see these other &quot;consumer&quot; facing options and websites appear as the more people see OSM the better our data becomes even if only a ting percentage of these can be converted into mappers. Obviously better information and simpler tools may help to lower the entry barrier in the future. The biggest recent impact has been from mapbox: Also a big shout out to the Stamen map styles and tiles: such as the toner style above or the acclaimed watercolour style that I used on the first slide. While we're on styles, we can't ignore the continuous improvement's to the OSM &quot;house&quot; style: The cycle map style: ] public transport style: ] and mapquest style ] again mapquest open provides a great example of a complete web mapping site, with search and routing. So provides a potential OSM powered  google maps replacement. So last year we did a comparison between the OS Locator dataset and OSM using the ITO Analysis tool, by region. I've added this years data into the table.

There have been some fantastic, improvements Glasgow was missing 171 roads last year and these have been accounted for. Dumfries And Galloway was bottom of the list last year and it's now in 7th, as has Aberdeen City. There are also some places such as Na H Eileanan An Iar; also known as the Outer Hebredies which are looking quite static. So what does that all add up to? In 2011, we  were shown as having 4316 Roads that hadn't been accounted for, so 93% match. When I looked a few days ago, we only  don't align on 1972 missing roads, or a 95% match. So what are these missing streets? I started by looking at the 9 roads highlighted in Edinburgh. The first stop are these Roads in Kirkliston, we seem to have one of these roads, but are missing the name, the other two roads are shown in OSM as under construction as below. So the conclusion is probably a draw on this one, it looks like neither OS Locator or OSM have the full picture, but a visit is needed. The next example is around Edinburgh Airport OSM Shows Almond Avenue, but OS Locator Almond drive. A visit here will need to take place to confirm who is right. Again it looks like some new houses here have led to some new developments that we don't yet have. This one was quite simple the Lane and the footpath should be joined, so I fixed this myself. I think that this one is a new development, that needs visiting. Again this one in Newhaven is probably a new development, that needs visiting. Interestingly in the few days since I gave this presentation, some of these have been fixed, by changes such as this one: &quot;Added missing street names from ITO in Kirkliston&quot; and this &quot;Added initial layout of new housing development in Newburgh, Edinburgh.&quot;. I really hope that these were done with local knowledge especially as adding the through road through Kirkliston doesn't looks like the kind of road layout that would be permitted as it would allow a rat run through a residential area. Anyway, we have evidence that OS Locator data can't always be relied upon. Already in Edinburgh 2.2% of roads in Edinburgh do not match what OS Locator shows. Glasgow, 1.4 % and looking at one of the other places at 100%, Kings's Lynn shows 7.4% out. This is really a warning, we should be using this as a datasource to help us know where to map, but this data cannot be relied upon. Something else was causing me concern, and that was in the Outer Hebrides. It also helps that I've holidayed and mapped here (or should it be the other way round) and so have lots of photos :) There weren't many changes in 2011 of 298 roads we were missing 5 and in 2012 the total roads is 297 and we're missing 4. So first thing, I thought that I would look at the last modification data of a selection of the objects: This wasn't quite what I expected, so  far this year there has been a lot of activity. And so I thought I would break down into months: So the basic level is quite small, but with a big peak in June and July. Looking in detail at June I saw, most of the changes: we're made by a single user, brianboru. I was very happy to see that he had been there and  and some of the information is surveyed on the ground with lots of detailed tracing of terrain, helping to fill in the map, so I thought I would see what else this user was up to? So he's from Birmingham, and by the looks of things he like I holidayed and did a ton of mapping and tracing whilse on holiday. But once I ignored the holiday based tracing binges, there is a steady background work by seumas, and looking at his page, I was again very pleased to see that he does live on the Island. and busy doing some mapping of shops, pubs, chippies and some paths: This was really for me the Golden Road, to be honest I didn't expect to find a local mapper living on the edge of the country, but here he is. So how much data do we have: Overall the breakdown over Scotland is: ]he uncompressed XML weighs in at 1.2G on disk, consisting of nearly 6 million nodes, nearly 500 000 ways and 5000 relations. I also ran this against a dump from before the licence change, and we have grown significantly since then, by over 600 000 nodes, and  30 000 ways. So we are well above the numbers from before the change, and thanks to the hard work of the community in Scotland to get local mappers on board and also to mitigate against loss I don't think we had any big problems. What's in a name? We have 36 660 named nodes and 134 724 named ways. Place? 6807 of these are places, from Cities down to Hamlets and localities. So how long are the ways: The table above lists the top 20 way types by length. The total, motorway length in OSM shows as 827km compares well with the total motorway length in wikipedia (once I remembered that OSM will have ways for both directions) We have 4 226km of paths, I suspefct there are a lot more in Scotland. We're up to 1 645 km of cycleway, and additionally cycling is permitted on a further 1000km of footways and paths. We have 53 km of steps, I wouldn't want to climb those all at once. There is also the longtail of the list: Somewhere we have 30m of broken bridge (not the one pictured), 10 km of racing track and 1 099m of train platforms. all made possible by OSM's flexable tagging system: and the 1776 users who have contributed! Last year I asked the question. I still don't think we have a really good answer to that question, but whatever we do, we must Tell People. It's the only way of improving the map.</summary></entry><entry><title type="html">State of the Map Scotland 2013 - The State of Scotland</title><link href="http://chrisfleming.org//openstreetmap/state-of-the-map-scotland-2012-the-state-of-scotland" rel="alternate" type="text/html" title="State of the Map Scotland 2013 - The State of Scotland" /><published>2012-10-25T12:37:41+01:00</published><updated>2012-10-25T12:37:41+01:00</updated><id>http://chrisfleming.org//openstreetmap/state-of-the-map-scotland-2012-the-state-of-scotland</id><content type="html" xml:base="http://chrisfleming.org//openstreetmap/state-of-the-map-scotland-2012-the-state-of-scotland">&lt;p&gt;Once again, this year, I had the pleasure of presenting the opening at our now, not so little State of the Map Scotland Conference, which was held at &lt;a href=&quot;http://inspace.mediascot.org/&quot;&gt;Inspace&lt;/a&gt; on the 19th and 20th October 2012.&lt;/p&gt;

  &lt;p&gt;(photo: &lt;a href=&quot;http://www.flickr.com/photos/xerones/131963343/&quot;&gt;http://www.flickr.com/photos/xerones/131963343/&lt;/a&gt;)&lt;/p&gt;

  &lt;p&gt;the &lt;a href=&quot;http://switch2osm.org/&quot;&gt;switch2osm&lt;/a&gt;, 2012 started with an announcement by &lt;a href=&quot;http://www.nestoria.co.uk/&quot;&gt;nestoria&lt;/a&gt; that they were moving over OSM.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.003.jpg&quot; alt=&quot;nestoria website&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;Another example is is &lt;a href=&quot;https://foursquare.com/&quot;&gt;foursquare. &lt;/a&gt;&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.004.jpg&quot; alt=&quot;foursquare website&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;I was amazed when I opened the site at the prominence given to the map on the foursquare homepage. This shouldn't be a surprise, given the nature of the site but I don't think  a google map would have  made the landing page here.&lt;/p&gt;

  &lt;p&gt;It was also interesting to watch the foursquare community, I think overall OSM has gained visibility and exposure from this change (citation needed)&lt;/p&gt;

  &lt;p&gt;Flickr has  &lt;a href=&quot;http://code.flickr.com/blog/2012/07/11/designing-an-osm-map-style/&quot;&gt;continued to have some OSM maps&lt;/a&gt; and improve those maps, despite a new deal yahoo has to switch to Nokia maps, has &lt;a href=&quot;http://code.flickr.com/blog/2012/07/11/designing-an-osm-map-style/&quot;&gt;continued to have some OSM maps. &lt;/a&gt;&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.005.jpg&quot; alt=&quot;iflickr map, showing Beijing&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;I would love to see  OSM as a layer across flickr's maps, the Nokia maps are a big improvement but are still aimed at car drivers and so still miss lots of places where photo's might be taken. Hopefully we will see  more OSM on flickr in the future.&lt;/p&gt;

  &lt;p&gt;Finally as a more personal example of a switch2osm. I switched my parents &lt;a href=&quot;http://www.bullfarmoast.co.uk/&quot;&gt;B&amp;amp;B in Kent &lt;/a&gt; over to use OSM.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.006.jpg&quot; alt=&quot;B&amp;amp;B at Bull Farm Oast, map page&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;This change was a little overdue, but for me is a milestone on my journey with OSM, I first discovered OpenStreetMap when I was trying to locate local attractions when I first added a google map to this site, back around 2006.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.007.jpg&quot; alt=&quot;Sissinghurst Castle information page.&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;I wasn't surprised by the detail on the &lt;a href=&quot;http://www.bullfarmoast.co.uk/attractions/Sissinghurst_Castle&quot;&gt;Sissinghurst page&lt;/a&gt;, as I mapped this myself.&lt;/p&gt;

  &lt;p&gt;but in fact zoomed in, almost every page such as this one for &lt;a href=&quot;http://www.bullfarmoast.co.uk/attractions/Bodiam_Castle&quot;&gt;Bodiam Castle&lt;/a&gt; has lots of the little bits of detail, such as the moat, ticket office and car park (not shown here).&lt;/p&gt;

  &lt;p&gt;A lot of this is now possible, because more and more companies are starting to provide services around OSM. As I said last year:&lt;/p&gt;

  &lt;p&gt;Rightly or wrongly &lt;strong&gt;OSM is currently setup largely as a data provider - &lt;/strong&gt;so it's really great to see these other &quot;consumer&quot; facing options and websites appear as the more people see OSM the better our data becomes even if only a ting percentage of these can be converted into mappers. Obviously better information and simpler tools may help to lower the entry barrier in the future.&lt;/p&gt;

  &lt;p&gt;The biggest recent impact has been from &lt;a href=&quot;http://mapbox.com/&quot;&gt;mapbox:&lt;/a&gt;&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.010.jpg&quot; alt=&quot;Mapbox website&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;Also a big shout out to the &lt;a href=&quot;http://maps.stamen.com/&quot;&gt;Stamen&lt;/a&gt; map styles and tiles:&lt;/p&gt;

  &lt;p&gt;such as the toner style above or the acclaimed watercolour style that I used on the first slide.&lt;/p&gt;

  &lt;p&gt;While we're on styles, we can't ignore the continuous improvement's to the OSM &quot;house&quot; style:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.012.jpg&quot; alt=&quot;OpenStreetMap - showing Aberdeen&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;The cycle map style:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.013.jpg&quot; alt=&quot;OpenStreetMap, cyclemap style, low zoom showing lots of scotland&quot; /&gt;]&lt;/p&gt;

  &lt;p&gt;public transport style:
  &lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.014.jpg&quot; alt=&quot;OSM Website, public transport style, centered on Glasgow.&quot; /&gt;]&lt;/p&gt;

  &lt;p&gt;and mapquest style

  &lt;p&gt;again &lt;a href=&quot;http://open.mapquest.co.uk/&quot;&gt;mapquest open&lt;/a&gt; provides a great example of a complete web mapping site, with search and routing. So provides a potential OSM powered  google maps replacement.&lt;/p&gt;

  &lt;p&gt;So last year we did a comparison between the OS Locator dataset and OSM using the ITO Analysis tool, by region. I've added this years data into the table.&lt;/p&gt;

  &lt;table&gt;

        &lt;th&gt;2012&lt;/th&gt;
        &lt;th&gt;“Missing”&lt;/th&gt;
        &lt;th&gt;2012 Roads&lt;/th&gt;
        &lt;th&gt;11 to 12 change&lt;/th&gt;
      &lt;/tr&gt;
      &lt;tr&gt;
        &lt;th&gt; &lt;/th&gt;
        &lt;th&gt;position&lt;/th&gt;
        &lt;th&gt; &lt;/th&gt;
        &lt;th&gt; &lt;/th&gt;
        &lt;th&gt; &lt;/th&gt;
        &lt;th&gt; &lt;/th&gt;
        &lt;th&gt; &lt;/th&gt;
      &lt;/tr&gt;
    &lt;/thead&gt;

      &lt;/tr&gt;
    &lt;/tbody&gt;
  &lt;/table&gt;

  &lt;p&gt;The first thing that struck me as that in both Edinburgh and Midlothian the total number of roads has increased, but we've missed some so we're not longer at 100%.&lt;/p&gt;

  &lt;p&gt;There have been some fantastic, improvements Glasgow was missing 171 roads last year and these have been accounted for. Dumfries And Galloway was bottom of the list last year and it's now in 7th, as has Aberdeen City.&lt;/p&gt;

  &lt;p&gt;There are also some places such as Na H Eileanan An Iar; also known as the Outer Hebredies which are looking quite static.&lt;/p&gt;

  &lt;p&gt;So what does that all add up to?&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.019.jpg&quot; alt=&quot;2011, 4316 Roads Missing from OSM Compared to OS, Scotland was 93% Complete. In 2012, 1972 Roads Missing. Scotland 95% Complete&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;In 2011, we  were shown as having 4316 Roads that hadn't been accounted for, so 93% match.&lt;/p&gt;

  &lt;p&gt;When I looked a few days ago, we only  don't align on 1972 missing roads, or a 95% match.&lt;/p&gt;

  &lt;p&gt;So what are these missing streets? I started by looking at the 9 roads highlighted in Edinburgh.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.020.jpg&quot; alt=&quot;ITO Analysis Map, showing missing new estate road names,&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;The first stop are these Roads in &lt;a href=&quot;http://www.openstreetmap.org/?lat=55.95985&amp;amp;lon=-3.40179&amp;amp;zoom=17&amp;amp;layers=M&quot;&gt;Kirkliston&lt;/a&gt;, we seem to have one of these roads, but are missing the name, the other two roads are shown in OSM as under construction as below.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.021.jpg&quot; alt=&quot;OSM Map showing &amp;quot;missing streets&amp;quot; as roads under contruction.&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;So the conclusion is probably a draw on this one, it looks like neither OS Locator or OSM have the full picture, but a visit is needed.&lt;/p&gt;

  &lt;p&gt;The next example is around &lt;a href=&quot;http://www.openstreetmap.org/?lat=55.944719016552&amp;amp;lon=-3.36523085832596&amp;amp;zoom=17&quot;&gt;Edinburgh Airport&lt;/a&gt;&lt;/p&gt;

  &lt;p&gt;OSM Shows Almond Avenue, but OS Locator Almond drive. A visit here will need to take place to confirm who is right.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.023.jpg&quot; alt=&quot;ITO Map, showing missing road&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;Again it looks like some new houses here have led to some new developments that we don't yet have.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.024.jpg&quot; alt=&quot;ITO Map, showing new estate&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;This one was quite simple the Lane and the footpath should be joined, so I fixed this myself.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.025.jpg&quot; alt=&quot;ITO Map&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;I think that this one is a new development, that needs visiting.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.026.jpg&quot; alt=&quot;ITO Map&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;Again this one in Newhaven is probably a new development, that needs visiting.&lt;/p&gt;

  &lt;p&gt;Interestingly in the few days since I gave this presentation, some of these have been fixed, by changes such as this one: &lt;a href=&quot;http://www.openstreetmap.org/browse/changeset/13611107&quot;&gt;&quot;Added missing street names from ITO in Kirkliston&quot;&lt;/a&gt; and this &quot;&lt;a href=&quot;http://www.openstreetmap.org/browse/way/187296573/history&quot;&gt;Added initial layout of new housing development in Newburgh, Edinburgh.&lt;/a&gt;&quot;. I really hope that these were done with local knowledge especially as adding the through road through Kirkliston doesn't looks like the kind of road layout that would be permitted as it would allow a rat run through a residential area.&lt;/p&gt;

  &lt;p&gt;Anyway, we have evidence that OS Locator data can't always be relied upon.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.027.jpg&quot; alt=&quot;How accurate is OS data? In Edinburgh 2.2% of names don't match, in Glasgow 1.4% of names don't match. Worst case in the UK, in King's Lynn and West Norfolkm 7.4% don't match.&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;Already in Edinburgh 2.2% of roads in Edinburgh do not match what OS Locator shows.&lt;/p&gt;

  &lt;p&gt;Glasgow, 1.4 % and looking at one of the other places at 100%, Kings's Lynn shows 7.4% out. This is really a warning, we should be using this as a datasource to help us know where to map, but this data cannot be relied upon.&lt;/p&gt;

  &lt;p&gt;Something else was causing me concern, and that was in the Outer Hebrides.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.028.jpg&quot; alt=&quot;How are we doing in Remote Places, like the Outer Hebrides&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;It also helps that I've holidayed and mapped here (or should it be the other way round) and so have lots of photos :)&lt;/p&gt;

  &lt;p&gt;There weren't many changes in 2011 of 298 roads we were missing 5 and in 2012 the total roads is 297 and we're missing 4.&lt;/p&gt;

  &lt;p&gt;So first thing, I thought that I would look at the last modification data of a selection of the objects:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.029.jpg&quot; alt=&quot;2006, 971, 2007: 10499, 2008: 2967, 2009: 7015, 2010: 61878, 2011: 8698, 2012: 26600&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;This wasn't quite what I expected, so  far this year there has been &lt;em&gt;a lot&lt;/em&gt; of activity.&lt;/p&gt;

  &lt;p&gt;And so I thought I would break down into months:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.030.jpg&quot; alt=&quot;&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;So the basic level is quite small, but with a big peak in June and July.&lt;/p&gt;

  &lt;p&gt;Looking in detail at June I saw, most of the changes:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.031.jpg&quot; alt=&quot;&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;we're made by a single user, brianboru. I was very happy to see that he had been there and  and some of the information is surveyed on the ground with lots of detailed tracing of terrain, helping to fill in the map, so I thought I would see what else this user was up to?&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.032.jpg&quot; alt=&quot;&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;So he's from Birmingham, and by the looks of things he like I holidayed and did a ton of mapping and tracing whilse on holiday.&lt;/p&gt;

  &lt;p&gt;But once I ignored the holiday based tracing binges, there is a steady background work by seumas, and looking at his page, I was again very pleased to see that he does live on the Island.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.033.jpg&quot; alt=&quot;&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;and busy doing some mapping of shops, pubs, chippies and some paths:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.034.jpg&quot; alt=&quot;&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;This was really for me the Golden Road, to be honest I didn't expect to find a local mapper living on the edge of the country, but here he is.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.035.jpg&quot; alt=&quot;&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;So how much data do we have:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.036.jpg&quot; alt=&quot;Cat - WHAT DO WE HAVE?&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;Overall the breakdown over Scotland is:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.037.jpg&quot; alt=&quot;1.2G of XML, 5 847 127 Nodes, 483 990 Ways, 5086 Relation Compared to before the license change, 5 206 480 Nodes, 451 091 Ways, 4844 Relations&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;]he uncompressed XML weighs in at 1.2G on disk, consisting of nearly 6 million nodes, nearly 500 000 ways and 5000 relations.&lt;/p&gt;

  &lt;p&gt;I also ran this against a dump from before the licence change, and we have grown significantly since then, by over 600 000 nodes, and  30 000 ways. So we are well above the numbers from before the change, and thanks to the hard work of the community in Scotland to get local mappers on board and also to mitigate against loss I don't think we had any big problems.&lt;/p&gt;

  &lt;p&gt;What's in a name?&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.0381.jpg&quot; alt=&quot;36 660 named nodes and 134 724 named ways&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;We have 36 660 named nodes and 134 724 named ways.&lt;/p&gt;

  &lt;p&gt;Place?&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.0391.jpg&quot; alt=&quot;6807 Names Places&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;6807 of these are places, from Cities down to Hamlets and localities.&lt;/p&gt;

  &lt;p&gt;So how long are the ways:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.040.jpg&quot; alt=&quot;&quot; /&gt;
  The table above lists the top 20 way types by length.&lt;/p&gt;

  &lt;p&gt;The total, motorway length in OSM shows as 827km compares well with the total motorway length in wikipedia (once I remembered that OSM will have ways for both directions)&lt;/p&gt;

  &lt;p&gt;We have 4 226km of paths, I suspefct there are a lot more in Scotland.&lt;/p&gt;

  &lt;p&gt;We're up to 1 645 km of cycleway, and additionally cycling is permitted on a further 1000km of footways and paths.&lt;/p&gt;

  &lt;p&gt;We have 53 km of steps, I wouldn't want to climb those all at once.&lt;/p&gt;

  &lt;p&gt;There is also the longtail of the list:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.041.jpg&quot; alt=&quot;&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;Somewhere we have 30m of broken bridge (not the one pictured), 10 km of racing track and 1 099m of train platforms.&lt;/p&gt;

  &lt;p&gt;all made possible by OSM's flexable tagging system:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.042.jpg&quot; alt=&quot;&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;and the 1776 users who have contributed!&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.0431.jpg&quot; alt=&quot;List of *all* contributors in Scotland&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;Last year I asked the question.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.044.jpg&quot; alt=&quot;How do we extend the community?&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;I still don't think we have a really good answer to that question, but whatever we do, we must Tell People.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.045.jpg&quot; alt=&quot;Tell people, OSM is not like fight club, Tell your sister mother brother, Tell your friends and enemies, Show everyone you meet, Go out your way to tell strangers&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;It's the only way of improving the map.&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-10-25-state-of-the-map-scotland-2013-the-state-of-scotland/main_presentation.046.jpg&quot; alt=&quot;Thank you. Follow me @chrisfl on twitter or @OSMScotland&quot; /&gt;&lt;/p&gt;</content><author><name>Chris Fleming</name></author><summary type="html">Once again, this year, I had the pleasure of presenting the opening at our now, not so little State of the Map Scotland Conference, which was held at Inspace on the 19th and 20th October 2012. When I started to write this talk, I wasn't sure where it was going to end up, I found it interesting and I hope that you do to. For me one of the most exciting trends, over the last year is seeing OpenStreetMap appearing invarious places: (photo: http://www.flickr.com/photos/xerones/131963343/) the switch2osm, 2012 started with an announcement by nestoria that they were moving over OSM. Triggered  by the ever improving quality of OSM, as well as google looking at charging, it was great to see this long term support switch to using our map. Another example is is foursquare.  I was amazed when I opened the site at the prominence given to the map on the foursquare homepage. This shouldn't be a surprise, given the nature of the site but I don't think  a google map would have  made the landing page here. It was also interesting to watch the foursquare community, I think overall OSM has gained visibility and exposure from this change (citation needed) Flickr has  continued to have some OSM maps and improve those maps, despite a new deal yahoo has to switch to Nokia maps, has continued to have some OSM maps.  I would love to see  OSM as a layer across flickr's maps, the Nokia maps are a big improvement but are still aimed at car drivers and so still miss lots of places where photo's might be taken. Hopefully we will see  more OSM on flickr in the future. Finally as a more personal example of a switch2osm. I switched my parents B&amp;amp;B in Kent  over to use OSM. This change was a little overdue, but for me is a milestone on my journey with OSM, I first discovered OpenStreetMap when I was trying to locate local attractions when I first added a google map to this site, back around 2006. I wasn't surprised by the detail on the Sissinghurst page, as I mapped this myself. but in fact zoomed in, almost every page such as this one for Bodiam Castle has lots of the little bits of detail, such as the moat, ticket office and car park (not shown here). A lot of this is now possible, because more and more companies are starting to provide services around OSM. As I said last year: Rightly or wrongly OSM is currently setup largely as a data provider - so it's really great to see these other &quot;consumer&quot; facing options and websites appear as the more people see OSM the better our data becomes even if only a ting percentage of these can be converted into mappers. Obviously better information and simpler tools may help to lower the entry barrier in the future. The biggest recent impact has been from mapbox: Also a big shout out to the Stamen map styles and tiles: such as the toner style above or the acclaimed watercolour style that I used on the first slide. While we're on styles, we can't ignore the continuous improvement's to the OSM &quot;house&quot; style: The cycle map style: ] public transport style: ] and mapquest style ] again mapquest open provides a great example of a complete web mapping site, with search and routing. So provides a potential OSM powered  google maps replacement. So last year we did a comparison between the OS Locator dataset and OSM using the ITO Analysis tool, by region. I've added this years data into the table. Place 2012 OS Locator 2012 “Missing” 2012 Roads 11 to 12 change   position           Edinburgh 4 4,760 4784 0 9 100 -&amp;gt; 99.81 Midlothian 6 1,180 1193 0 9 100 -&amp;gt; 99.25 Clackmannanshire 1 817 819 5 0 99.27 -&amp;gt; 100 South Lanarkshire 5 5432 5491 73 34 98.55 -&amp;gt; 99.38 West Dunbartonshire 9 1,233 1236 18 15 98.54 -&amp;gt; 98.79 Shetland Islands 8 309 311 6 3 98.06 -&amp;gt; 99.04 Stirling 12 1,361 1370 29 37 97.58 -&amp;gt; 97.30 East Ayrshire 16 2039 2052 50 64 97.50 -&amp;gt; 96.83 Glasgow City 1 6758 6761 171 0 97.44 -&amp;gt; 100% West Lothian 15 2030 2038 48 59 97.44 -&amp;gt; 96.96% Inverclyde 13 1239 1240 32 34 97.42 -&amp;gt; 97.26% Na H Eileanan An Iar 10 298 297 5 4 97.32 -&amp;gt; 98.98% East Lothian 11 1343 1353 33 32 97.10 -&amp;gt; 97.19% North Ayrshire 14 2180 2189 63 63 97.06 -&amp;gt; 98.08% Dundee City 20 2223 2229 65 76 97.03 -&amp;gt; 96.55% Angus 18 1877 1878 57 59 96.91 -&amp;gt; 96.81 South Ayrshire 22 1803 1809 61 69 96.45 -&amp;gt; 96.08 Argyll And Bute 21 1400 1403 50 48 96.43 -&amp;gt; 96.58 Monmouthshire 17 1529 1538 52 48 96.34 -&amp;gt; 96.81 Fife 23 5607 5627 217 228 95.93 -&amp;gt; 95.75 Scottish Borders 24 1890 1902 78 79 95.77 -&amp;gt; 95.74 East Renfrewshire 27 1323 1328 57 60 95.62 -&amp;gt; 95.41 Aberdeen City 1 2772 2774 125 0 95.27 -&amp;gt; 100 Highland 28 3443 3483 535 388 84.05 -&amp;gt; 88.46 Aberdeenshire 25 3886 3936 626 167 83.63 -&amp;gt; 95.73 Renfrewshire 26 2447 1378 430 60 82.18 -&amp;gt; 95.41 Perth and Kinross 19 2409 2424 478 79 79.91 -&amp;gt; 96.45 Dumfries And Galloway 7 2556 2580 586 22 76.53 -&amp;gt; 99.15 Moray 29 1545 1581 366 226 75.92 -&amp;gt; 85.45 The first thing that struck me as that in both Edinburgh and Midlothian the total number of roads has increased, but we've missed some so we're not longer at 100%. There have been some fantastic, improvements Glasgow was missing 171 roads last year and these have been accounted for. Dumfries And Galloway was bottom of the list last year and it's now in 7th, as has Aberdeen City. There are also some places such as Na H Eileanan An Iar; also known as the Outer Hebredies which are looking quite static. So what does that all add up to? In 2011, we  were shown as having 4316 Roads that hadn't been accounted for, so 93% match. When I looked a few days ago, we only  don't align on 1972 missing roads, or a 95% match. So what are these missing streets? I started by looking at the 9 roads highlighted in Edinburgh. The first stop are these Roads in Kirkliston, we seem to have one of these roads, but are missing the name, the other two roads are shown in OSM as under construction as below. So the conclusion is probably a draw on this one, it looks like neither OS Locator or OSM have the full picture, but a visit is needed. The next example is around Edinburgh Airport OSM Shows Almond Avenue, but OS Locator Almond drive. A visit here will need to take place to confirm who is right. Again it looks like some new houses here have led to some new developments that we don't yet have. This one was quite simple the Lane and the footpath should be joined, so I fixed this myself. I think that this one is a new development, that needs visiting. Again this one in Newhaven is probably a new development, that needs visiting. Interestingly in the few days since I gave this presentation, some of these have been fixed, by changes such as this one: &quot;Added missing street names from ITO in Kirkliston&quot; and this &quot;Added initial layout of new housing development in Newburgh, Edinburgh.&quot;. I really hope that these were done with local knowledge especially as adding the through road through Kirkliston doesn't looks like the kind of road layout that would be permitted as it would allow a rat run through a residential area.

I'm pretty sure that this has been the best attended of our mapping parties with more new people than old, I didn't do a count but easily over 20.&lt;/p&gt;

  &lt;p&gt;New Lanark itself, is a World Heritage Site was originally founded in 1786 as Cotton Mills and Housing for the workers, it's an early example of planned urban development and the business itself was run with consideration for the well being of the workers and lead the way in reform, socialism and welfare. But the &lt;a href=&quot;http://en.wikipedia.org/wiki/New_Lanark&quot;&gt;wikipedia article&lt;/a&gt; covers this, and is well worth a read.&lt;/p&gt;

  &lt;p&gt;The area either side of the cycle is the Scottish Wildlife Trust's &lt;a href=&quot;http://scottishwildlifetrust.org.uk/reserve/falls-of-clyde/&quot;&gt;Falls of Clyde a nature reserve&lt;/a&gt;&lt;/p&gt;

    &lt;/figcaption&gt;
  &lt;/figure&gt;

  &lt;p&gt;The day started with a quick get together, where we choose our slices of the area to map, with Bob and Tim taking the new mappers around the village and because the mapping party was sponsored by &lt;a href=&quot;http://www.centralscotlandgreennetwork.org/&quot;&gt;The Central Scotland Green Network Community Fund&lt;/a&gt;  I picked a green area with other side of the Clyde, without quite realising how far it was to get to a bridge to cross….&lt;/p&gt;

  &lt;p&gt;This didn't matter as the the morning's rain cleared and the sun came out, the scenery was quite special.&lt;/p&gt;

  &lt;p&gt;although parts of the area had been mapped in advance, there were lots of details to add:&lt;/p&gt;

  &lt;p&gt;&lt;a href=&quot;http://www.flickr.com/photos/61663261@N00/6806253372/&quot;&gt;&lt;img src=&quot;http://farm8.staticflickr.com/7202/6806253372_eeca3921ee_m.jpg&quot; alt=&quot;Seats&quot; /&gt;&lt;/a&gt;&lt;a href=&quot;http://www.flickr.com/photos/61663261@N00/6806262524/&quot;&gt;&lt;img src=&quot;http://farm8.staticflickr.com/7041/6806262524_a81be1d683_m.jpg&quot; alt=&quot;Private Path.&quot; /&gt;&lt;/a&gt;&lt;/p&gt;

  &lt;p&gt;as well as the obligatory danger signs:&lt;/p&gt;

  &lt;p&gt;&lt;a href=&quot;http://www.flickr.com/photos/61663261@N00/6806248684/&quot;&gt;&lt;img src=&quot;http://farm8.staticflickr.com/7063/6806248684_6ed008bb92.jpg&quot; alt=&quot;DANGER!&quot; /&gt;&lt;/a&gt;&lt;/p&gt;

  &lt;p&gt;and closed roads, which &lt;a href=&quot;http://refnum.com/&quot;&gt;Dair&lt;/a&gt; - seen running out had already covered.&lt;/p&gt;

  &lt;p&gt;&lt;a href=&quot;http://www.flickr.com/photos/61663261@N00/6806257320/&quot;&gt;&lt;img src=&quot;http://farm8.staticflickr.com/7070/6806257320_405d19a7c7.jpg&quot; alt=&quot;Road Closed.&quot; /&gt;&lt;/a&gt;&lt;/p&gt;

  &lt;p&gt;In all we covered 11km of mostly footpaths, I was glad of the lack of tree cover at the moment which meant that I could vastly improve area's such as this windy downhill:&lt;/p&gt;

  &lt;p&gt;&lt;img src=&quot;/post-assets/2012-03-05-new-lanark-mapping-party/map-3.png&quot; alt=&quot;&quot; /&gt;&lt;/p&gt;

  &lt;p&gt;and some more urban mapping:&lt;/p&gt;

  &lt;p&gt;&lt;a href=&quot;http://www.flickr.com/photos/61663261@N00/6952382307/&quot;&gt;&lt;img src=&quot;http://farm8.staticflickr.com/7188/6952382307_265b09b099_m.jpg&quot; alt=&quot;House Number&quot; /&gt;&lt;/a&gt;&lt;a href=&quot;http://www.flickr.com/photos/61663261@N00/6806268122/&quot;&gt;&lt;img src=&quot;http://farm8.staticflickr.com/7065/6806268122_e27cc948ff_m.jpg&quot; alt=&quot;Street Sign&quot; /&gt;&lt;/a&gt;&lt;/p&gt;

  &lt;p&gt;By the time we got back, we had missed lunch but it was good to see everyone busy processing the afternoon's work:&lt;/p&gt;

  &lt;!-- more --&gt;

  &lt;p&gt;In all it was a great success, and a huge thanks go to Tim for doing the hard work of organising the day, sponsorship, venue and publicising the event. There is a &lt;a href=&quot;http://wiki.openstreetmap.org/wiki/Workshop/Glasgow2012&quot;&gt;mapping workshop in Glasgow&lt;/a&gt; on the 17 March and our next social meetup is on the &lt;a href=&quot;http://wiki.openstreetmap.org/wiki/Edinburgh#Upcoming_Pub_Meetings&quot;&gt;20th March in Edinburgh.&lt;/a&gt;&lt;/p&gt;
