  We expected to hit the mark of 2,000,000 registered members during the last weekend, and meanwhile we passed it (thanks to Pascal for the stats and the tweet). That&#8217;s &#8220;slightly&#8221; more than the amount of members at the time I joined the project (August 29, 2006).

summary:
  I just was notified that MoNav, a routing application for the Nokia N900 I helped to develop, is available for the Jolla phone respectively the Sailfish OS. An installer is avilable via Openrepos.net. The source is hosted at Github. Some map material is available here. I&#8217;m glad the code I wrote about three years ago [&#8230;]

  Due to the weather conditions in germany (and the lack of a summer vacation), I decided to leave for a couple of days. I was looking for a warmer, less rainy, and easy to reach destination, which allowed for some hiking. Madeira was the perfect candidate. To read the rest of this entry, simply klick [&#8230;]

  <p><span id="more-9617"></span></p>
  <p><strong>Osmand</strong></p>
  <p>I used <a href="https://play.google.com/store/apps/details?id=net.osmand">Osmand</a> (alternative download via <a href="https://f-droid.org/repository/browse/?fdfilter=osmand&#038;fdid=net.osmand.plus">f-droid.org</a>) for a couple of purposes:</p>
  <ul>
  <li>provide speech instructions to navigate from the accommodation to the hiking destinations.</li>
  <li>display pre-downloaded GPX tracklogs as breadcrumbs on top of the map.</li>
  <li>record the trip as a tracklog and allow to insert waypoints with descriptions for mapping purposes, e.g. to improve the openstreetmap data set.</li>
  <li>display <a href="https://play.google.com/store/apps/details?id=net.osmand.srtmPlugin.paid">elevation contour lines</a> (<a href="https://f-droid.org/repository/browse/?fdfilter=osmand&#038;fdid=net.osmand.srtmPlugin.paid">f-droid.org</a> alternative download) based on SRTM data, which are available for additional download from within Osmand after installing the plugin.</li>
  </ul>
  <p>Osmand is a bit awkward to use some times, but since I am used to it for some time now, I have to say it did a pretty good job. The openstreetmap data set of the island is impressive, so navigation was no issue at all. The speech instructions are very useful, thought sometimes a bit verbose and confusing at times. I recommend to use a suction mount so the displayed route supports the understanding of the speech instructions.</p>
  <p>What I&#8217;m still struggling with is track logging. Osmand provides four profiles, which read as &#8220;Map&#8221;, &#8220;Car&#8221;, &#8220;Bike&#8221;, and &#8220;Pedestrian&#8221;. Enabling logging is not enough. In case one wants to keep Osmand logging even in case the phone&#8217;s screen is off, background logging must also be enabled. Some times Osmand forgets that the setting was enabled, even when immediately revisiting the options dialog. Additionally, this setting depends on the abovementioned profiles. Even in case it was enabled for the &#8220;Car&#8221; profile, it may be off as soon as the profile changes. And the profile also changes to &#8220;Map&#8221; after restarting Osmand, effectively switching off background logging.</p>
  <p>Displaying a tracklog on top of the map is also limited. It won&#8217;t work in the default Map mode. The user has to switch to one of the other modes first. Otherwise Osmand asks to enable track logging first. Also, Osmand does not remember permanently in case one enables to display the currently recorded track.</p>
  <p>Despite the minor glitches, Osmand is a swiss army knife and a mappers dream. In case one only wants track logging, I&#8217;d recommend a dedicated logger or some other app. In case one needs a multi purpose app, Osmand is for you. Offline vector data is available, the map rendering performance is pretty good, the map is highly configurable (including points of interest), it can display third party tracklogs, and last but not least, it can provide speed warnings in case one drives too fast.</p>
  <p><strong>osm2go</strong></p>
  <p>Unfortunately I coudn&#8217;t use osm2go for on-site mapping, since the IP connectivity was so poor that osm2go timed out during my attempts to download the areas of the hiking trips. It&#8217;s a pity, since I love to use the beloved Nokia N900 for on-site mapping when hiking.</p>
  <p><strong>Openstreetmap</strong></p>
  <p>The data of the island is quite good. I added a lot of details and fixed some minor issues anyway.</p>
  <p>What I really dislike are relations, since they often hinder some minor fix for the sake of keeping a relation intact, despite one senses that the relation is of little use. For example, Osmand did not provide the usual turn instructions for two <a href="http://www.openstreetmap.org/?mlat=32.71211&#038;mlon=-17.15249#map=18/32.71211/-17.15249">roundabouts in Arco de Calheta</a>. Thus I wanted to make them roundabouts. Unfortunately those were split, with sections showing different directions, opposite oneways (does anyone remember unordered segments?!?), and different route relations including partial sections of the roundabout.</p>
  <p>Sometimes the levadas are covered by sheets of concrete, so the path leads directly on top of the levada. This often is due to the lack of space for a separate way. In those particular cases, one would tag a way with both waterway=ditch as well as highway=path. But for the ditch, one would like to add a tunnel=yes (or even layer=-1), while this does not apply to the path. Since there&#8217;s no simple solution for this problem, I accept it this way.</p>
  <p>But even worse, some of the levadas consist of one way only, despite the fact that the path is beside the levada. The mapping approach is valid (&#8220;a levada always consists of the waterway and the path&#8221;), but has some disadvantages (e.g. sometimes the path deviates from the levada). I didn&#8217;t fix such issues, once again due to the fact that some relations have been used to put the sections of the levada in one levada relation, or to put the levada in a hiking route relation.</p>
  <p><strong>Camera</strong></p>
  <p>The pictures have been taken using a Samsung NX30, a mirrorless camera. I dislike some things. The auto stitching is rather limited in image size, it often fails during processing, and it often fails to stitch the images correctly. In manual focus mode, it is not possible to pan the focus loupe to somewhere else than the center of the image. The camera has no built-in GPS receiver, and the ED-GPS10 I used for the NX300 is not compatible.</p>
  <p>On the other hand, I&#8217;m quite content with the device. In case someone asks me for a good camera, my stock answer is a Samsung NX300 for more point-and-shoot oriented customers and NX30 for more ambitious users.</p>
  <p>The lens I used was the EX-T50200CSB 50-200 mm. It did a very good job. However, I missed my wide angle lenses rather often. Samsung provides the L18200MB 18-200 mm. It is expensive, and one has to consider a compromise concerning the quality for the impressive zoom range.</p>
  <p>I left the tripod and the ball head at home due to the weight. Instead I used a bean bag which served me very well. Of course it is less flexible than a tripod, but many of the pictures taken, especially the ones with long exposure times, would not have been possible without it.</p>
  <p><strong>Hiking</strong></p>
  <p>I used the GPS tracks provided by <a href="http://www.madeira-tipps.de/40,2,0,listenuebersicht,index,0.html">madeira-tipps.de</a> (german language). I rent a car on-site, since it turned out to be demanding to get to the hiking trails by third party transportation.</p>

  <p>This is a starter trip above Funchal, just an easy walk along a bigger levada. It was relatively quiet, but I was not the only one along the path.</p>
  <p>I placed the car at some <a href="http://www.openstreetmap.org/?mlat=32.66714&#038;mlon=-16.87801#map=18/32.66714/-16.87801">parking lots</a>.

  <p>A relatively small levada in a nice valley. I&#8217;d not call it a walk, but it&#8217;s still convenient to follow. I met about 6 other hikers, so it&#8217;s relatively quiet. <a href="http://www.openstreetmap.org/?mlat=32.76747&#038;mlon=-16.85052#map=18/32.76747/-16.85052">Parking</a> is possible using the street.</p>

  <p>This is the levada found in many glossy brochures. It&#8217;s a nice one, with some fall between two tunnels. As a consequence, you won&#8217;t be the only visitor, though I&#8217;d not call it overcrowded.</p>
  <p>I started at a popular <a href="http://www.openstreetmap.org/?mlat=32.85145&#038;mlon=-17.16657#map=18/32.85145/-17.16657">viewpoint and picknick place</a>. The first few meters provide some further picknick places, and a lot of lizards are populating the rocks.</p>
  <p>The first tunnel is a straight line (though the levada leaves it a <a href="http://www.openstreetmap.org/?mlat=32.82764&#038;mlon=-17.18090#map=18/32.82764/-17.18090">couple of meters</a> before its end) and provides dimensions of about 2 meters in height and 1,2 meters in width. The exit is always visible. The levada requires most of its width, so only a couple of centimeters remain to walk, and those are often covered with some water.</p>
  <p>After the first tunnel, a small shelter construction provides protection from some <a href="http://www.openstreetmap.org/?mlat=32.82450&#038;mlon=-17.18072#map=18/32.82450/-17.18072">water falling down</a>. A rain coat is useful anyway.</p>

  <p>The <a href="http://www.openstreetmap.org/?mlat=32.82431&#038;mlon=-17.18019#map=18/32.82431/-17.18019">second tunnel</a> consists of two sraightforward segments and is as easy to pass as the first one.</p>
  <p>The next facility is a <a href="http://www.openstreetmap.org/?mlat=32.82428&#038;mlon=-17.17585#map=18/32.82428/-17.17585">small house</a> used by the Levadeiros. A couple of meters further one will find the next tunnel, which I didn&#8217;t take. Instead, I returned the same way I came along.</p>
  <p>About 5 hours are required for this trip.</p>
  <p>Three things are required for this trip. Hiking boots, rain coat, and a torch. Additionally I recommend some repellent against flies (danger of <a href="https://en.wikipedia.org/wiki/Dengue_fever">Dengue fever</a>) and ticks (<a href="https://en.wikipedia.org/wiki/Lyme_disease">Lyme disease</a>).</p>

  <p>Sometimes people compare this elevated plain with Scotland. Well, at least I found the cattle grids reminiscent :) .</p>
  <p>This was a relatively short trip around the peak of <a href="http://www.openstreetmap.org/?mlat=32.7573&#038;mlon=-17.0591#map=16/32.7573/-17.0591">Bica da Cana</a> (1620 meters), but of great fun anyway. After descending through the bushes (and admiring the many <a href="https://en.wikipedia.org/wiki/Lichen">lichen</a>), I followed a small levada which just starts along the way. I left the levada to get back to the top of the peak and then visiting the nearby picknick facilities.</p>

  <p>This trip is not a convenient one anyway. Hiking boots, strong trousers, and a rain coat as a minimum are required.<br />
  Additionally, due to the altitude, it is much cooler than at the coast.</p>
  <p><strong>Levada do Alecrim (Ribeira Grande)</strong></p>
  <p><a href="http://www.christeck.de/wp/2015/01/02/spontaneous-xmas-vacation-2014/samsung-csc-353/" rel="attachment wp-att-9647"><img src="http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412250039-201x300.jpg" alt="" width="201" height="300" class="aligncenter size-medium wp-image-9647" srcset="http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412250039-201x300.jpg 201w, http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412250039-686x1024.jpg 686w, http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412250039-624x930.jpg 624w, http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412250039.jpg 912w" sizes="(max-width: 201px) 100vw, 201px" /></a></p>
  <p>There is a parking lot above the house of Rabacal, the entry to some other levadas. To reach the levada do Alecrim, leave the road to Rabacal immediately <a href="http://www.openstreetmap.org/?mlat=32.75374&#038;mlon=-17.13284#map=19/32.75374/-17.13284">after the lift gate</a> at the power pole and cross the meadow. Note that all levadas near Rabacal are well visited, even the levada do Alecrim.</p>
  <p>The levada grabs the water of several springs and a stream. It also includes a fish ladder.</p>
  <p><a href="http://www.christeck.de/wp/2015/01/02/spontaneous-xmas-vacation-2014/samsung-csc-354/" rel="attachment wp-att-9648"><img src="http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412250058-300x200.jpg" alt="" width="300" height="200" class="aligncenter size-medium wp-image-9648" srcset="http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412250058-300x200.jpg 300w, http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412250058-1024x682.jpg 1024w, http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412250058-624x416.jpg 624w, http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412250058.jpg 1368w" sizes="(max-width: 300px) 100vw, 300px" /></a></p>
  <p>At its origin, a small fall invites for some more photos with long exposure times. The paths on the other side of the valley lead to nowhere. IMO it&#8217;s not worth exploring them.</p>
  <p>The way back leads the hiker the very same path. At some point, a path from above is crossing, which allows to enter the other levadas of the Rabacal area.</p>
  <p>This is one further trip where some rain coat, hiking boots and strong clothes are useful.</p>
  <p><strong>Levada do Risco, 25 Fontes, and Rocha Vermelha</strong></p>
  <p><a href="http://www.christeck.de/wp/2015/01/02/spontaneous-xmas-vacation-2014/samsung-csc-355/" rel="attachment wp-att-9650"><img src="http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412260018-300x200.jpg" alt="" width="300" height="200" class="aligncenter size-medium wp-image-9650" srcset="http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412260018-300x200.jpg 300w, http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412260018-1024x682.jpg 1024w, http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412260018-624x416.jpg 624w, http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412260018.jpg 1368w" sizes="(max-width: 300px) 100vw, 300px" /></a></p>
  <p>Once again the hiker leaves the car at the road to <a href="http://www.openstreetmap.org/?mlat=32.7617&#038;mlon=-17.1349#map=16/32.7617/-17.1349">Rabacal</a>. Sometimes a shuttle bus brings tourists to Rabacal, except on public holidays. Alternatively one uses her feet.</p>
  <p>At Rabacal there are some picknick facilities. Some steps lead to the levadas. The first one is the Levada do Risco. In the afternoon hours it is on the shady side of the valley, so I decided to choose the <a href="http://www.openstreetmap.org/?mlat=32.76223&#038;mlon=-17.13013#map=17/32.76223/-17.13013">steps down to the Levada das 25 Fontes</a>. This one also is relatively small, about 30 times 30 centimeters.</p>
  <p>The path is narrow, and there is some touristic traffic. The trip is worth the effort anyway. There is an interesting bridge with steps down on either side, where the water of the levada also follows the steps and the bridge.</p>
  <p><a href="http://www.christeck.de/wp/2015/01/02/spontaneous-xmas-vacation-2014/samsung-csc-356/" rel="attachment wp-att-9651"><img src="http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412260028-300x200.jpg" alt="" width="300" height="200" class="aligncenter size-medium wp-image-9651" srcset="http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412260028-300x200.jpg 300w, http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412260028-1024x682.jpg 1024w, http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412260028-624x416.jpg 624w, http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412260028.jpg 1368w" sizes="(max-width: 300px) 100vw, 300px" /></a></p>
  <p>The trail now is on the sunny side of the valley, before the levada turns to the shady side. After a couple of meters the levada splits. The smaller one goes over a small bridge. The bigger one comes from the right from a fish ladder, which is fed by a <a href="http://www.openstreetmap.org/?mlat=32.76553&#038;mlon=-17.12584#map=19/32.76553/-17.12584">picturesque water fall</a>. It&#8217;s no wonder that this trail is that well visited.</p>

  <p>Following the smaller levada over the bridge leads to some more quiet section of the trail.</p>
  <p><a href="http://www.christeck.de/wp/2015/01/02/spontaneous-xmas-vacation-2014/samsung-csc-359/" rel="attachment wp-att-9654"><img src="http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412260062-300x200.jpg" alt="" width="300" height="200" class="aligncenter size-medium wp-image-9654" srcset="http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412260062-300x200.jpg 300w, http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412260062-1024x682.jpg 1024w, http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412260062-624x416.jpg 624w, http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412260062.jpg 1368w" sizes="(max-width: 300px) 100vw, 300px" /></a></p>

  <p>On the way back, I took a small <a href="http://www.openstreetmap.org/?mlat=32.76619&#038;mlon=-17.13115#map=17/32.76619/-17.13115">path downhill</a> to the Levada da Roche Vermelha. It is bigger than the other ones, and I followed it in direction of its flow. After a metal bridge one has to take a <a href="http://www.openstreetmap.org/?mlat=32.76432&#038;mlon=-17.13128#map=17/32.76432/-17.13128">small path uphill</a> instead of the tunnel.</p>

  <p>I cannot recommend this path. Parts are paved or built as steps, but other parts are blown away by some earth slide. The incline thus is a dangerous one. Until it is repaired, avoid it.</p>
  <p><a href="http://www.christeck.de/wp/2015/01/02/spontaneous-xmas-vacation-2014/samsung-csc-362/" rel="attachment wp-att-9657"><img src="http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412260103-201x300.jpg" alt="" width="201" height="300" class="aligncenter size-medium wp-image-9657" srcset="http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412260103-201x300.jpg 201w, http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412260103-686x1024.jpg 686w, http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412260103-624x930.jpg 624w, http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412260103.jpg 912w" sizes="(max-width: 201px) 100vw, 201px" /></a></p>
  <p>After this section, one reaches the levada des 25 Fontes again. Before it ends in some rather long tunnel, some <a href="http://www.openstreetmap.org/?mlat=32.76203&#038;mlon=-17.13609#map=17/32.76203/-17.13609">steps</a> lead back to Rabacal and, following the road, to the car. It may well be that it&#8217;s now foggy and much cooler than at noon. I used the last sun rails for the following pictures.</p>

  <p>This trip starts at a <a href="http://www.openstreetmap.org/?mlat=32.80914&#038;mlon=-17.14412#map=17/32.80914/-17.14412">picknick site</a> near Fanal. Following the road in direction of Paul da Serra, a small path leads to a rather <a href="http://www.openstreetmap.org/?mlat=32.80166&#038;mlon=-17.14304#map=17/32.80166/-17.14304">huge amount of steps</a>, which lead down from about 1000 meters of altitude to about 900 meters. The samll levada, about 25 times 5 centimeters, is now reached near its origin. A nice <a href="http://www.openstreetmap.org/?mlat=32.79915&#038;mlon=-17.14427#map=17/32.79915/-17.14427">water fall</a> can be used for some long exposure pictures.</p>

  <p>This levada looses a lot of water, but is still maintained.</p>

  <p>The main attraction are the old laurels, covered by lichen. Additionally it&#8217;s a quite quiet trip.</p>
  <p>I left the levada where it <a href="http://www.openstreetmap.org/?mlat=32.8259&#038;mlon=-17.1580#map=16/32.8259/-17.1580">crosses the main road</a>. Frankly, the incline back to the car was a hard one, and meanwhile it was foggy and cool.</p>

  <p>The next time I would try to leave the car near the crossing, follow the levada, take the steps and then follow the road <em>downhill</em>. An alternative could be following the levada forth and back.</p>

  <p>Instead of following the instructions of the routing software, which lead to some narrow and steep residential roads, I recommend to head to Ponta do Sol and to take the ER226 via the roundabout.</p>
  <p>The levada passes right at the back of the church, and there are some <a href="http://www.openstreetmap.org/?mlat=32.68938&#038;mlon=-17.09167#map=17/32.68938/-17.09167">parking lots</a> in front of it.</p>
  <p>The levada is a small one and only maintained at minimum effort. One can see that it was more important in former times, when it was used to water the many gardens, but nowadays most parcels are disused.</p>
  <p><a href="http://www.christeck.de/wp/2015/01/02/spontaneous-xmas-vacation-2014/samsung-csc-373/" rel="attachment wp-att-9679"><img src="http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412280002-300x85.jpg" alt="" width="300" height="85" class="aligncenter size-medium wp-image-9679" srcset="http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412280002-300x85.jpg 300w, http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412280002-1024x290.jpg 1024w, http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412280002-624x177.jpg 624w, http://www.christeck.de/wp/wp-content/uploads/christeck.de/2015/01/Madeira-201412280002.jpg 1296w" sizes="(max-width: 300px) 100vw, 300px" /></a></p>
  <p>Some of the garden inhabitants are ticks, so a repellent is recommended. Near its origin, some picknick places can be found on the other side of the river.</p>
  <p>Some <a href="http://www.openstreetmap.org/?mlat=32.71676&#038;mlon=-17.08416#map=17/32.71676/-17.08416">newly built steps</a> lead to the levada nova. It is much bigger, approximately 40&#215;15 centimeters in size. After a while one reaches a <a href="http://www.openstreetmap.org/?mlat=32.71379&#038;mlon=-17.08375#map=18/32.71379/-17.08375">deep cut</a>. At its deepest point, a stream comes from above. A horizontal duct for the levada was built around the rocks and behind the fall. A rain coat is useful anyway.</p>

  <p>After this fall a straight tunnel follows.</p>

  <p>Despite those obstacles the levada nova is a quite easy walk, though I&#8217;d like to emphasize once again that strong clothes, hiking boots, rain coat, torch, and repellent are required to enjoy the trip.</p>

  <p><strong>Conclusion</strong></p>
  <p>If I remember correctly, I never was on vacation during the Xmas break, since it is the time to visit friends and family members. I booked the trip just a couple of days before the departure, and work was rather intense until the day before I left.</p>
  <p>I didn&#8217;t relax that much. I had nine days, and I did nine hiking trips. The climate was better than expected. I never used a coat, and the rain did me a favour and returned just a couple of hours before I left. At the same time, germany was covered by snow.<br />
  Last but not least, I&#8217;m glad I booked a car the day I arrived. The trips haven&#8217;t been possible using public transportation.</p>
  <p>A great trip, worth every cent.</p>

title: I Am Not At State Of The Map 2013 But There Is A Viral Map

summary:
  Today is the 7th. of <a href="http://maptember.org/" target="_blank">Maptember</a> 2013 and that means I should be in Birmingham for the OpenStreetMap <a href="http://2013.stateofthemap.org/" target="_blank">State Of The Map</a> conference. But I'm not; I'm still at home in the suburbs of South West London. But I will still be appearing at SOTM. Virtually.

content:
  <p>Due to the age old cliche of <em>circumstances beyond my control</em>, I can&#8217;t be in Birmingham this weekend, despite submitting <em>How To Make A Map Go Viral (In 8 Easy Steps)</em> as a talk for the SOTM conference. But thanks to the wonders of modern digital technology, in other words, a screencast, my talk is still on the conference schedule, even if I&#8217;m not.</p>
  <p>The talk is an update to one of the same title that I gave at <a href="http://geomobldn.org/post/44291757142/spring-geomob-25th-of-april-at-ucl" target="_blank">London&#8217;s GeoMob</a> back in April of this year and was submitted to the SOTM committee with this abstract &#8230;</p>
  <blockquote><p>In February of 2013 I mashed up a geocoded list of global place names and made a map of them using nothing more than Stamen&#8217;s OSM based Toner tile-set and the Leaflet maps API. I then promptly forgot about it. But Twitter had other ideas and the Vaguely Rude Place Names map went viral resulting in a month&#8217;s worth of media madness. This is the story of how the map came to be and what happened when traditional media met social media &#8230; on a map. It&#8217;s also the story of how the combination of rude names, innuendo and maps briefly appealed to people the world over.</p></blockquote>
  <p>When I learned that I wouldn&#8217;t be able to go to Birmingham, the conference organisers kindly suggested that maybe I might want to pre-record my talk instead. Which is just what I&#8217;ve done. You&#8217;ll see it embedded below.</p>

  <p>Apart from a few cosmetic changes and updates, it&#8217;s the same talk as I gave in April and if you&#8217;re interested in my notes and slides, you&#8217;ll find them in <a href="http://www.vicchi.org/2013/04/26/how-a-map-can-go-viral/" target="_blank">my write up from April</a>.</p>
  <p>If you were lucky enough to have been at SOTM this year, I hope you enjoyed the conference and I hope you enjoyed my talk and that my disembodied voice wasn&#8217;t too off putting. This is the first screencast I&#8217;ve put together, so be gentle. See you all at SOTM next year. Hopefully.</p>

  <p>Most things in life are a journey and the destination of this particular journey was to try and create a custom map style that represented the unique features and challenges of Tandale.</p>

  <p>Which meant I needed to download and install <a href="http://mapbox.com/tilemill/" target="_blank">TileMill</a>, an interactive map design tool.</p>
  <p>Which meant I needed to learn <a href="https://github.com/mapbox/carto/" target="_blank">Carto</a>, the CSS-like language for map styling.</p>
  <p>Which meant I looked for a template project so I didn&#8217;t have to start from scratch.</p>
  <p>Which meant I found <a href="https://github.com/mapbox/osm-bright" target="_blank">OSM Bright</a>.</p>
  <p>Which meant I needed to start small and find a map extract of Tanzania to work with.</p>
  <p>Which meant I needed to install and configure <a href="http://www.postgresql.org/download/macosx/" target="_blank">PostgreSQL</a> and <a href="http://postgis.refractions.net/download/" target="_blank">PostGIS</a> on my Mac.</p>
  <p>Which brings me to the starting point of the journey and the reason for this post in the first place.</p>
  <p>When I normally need to install UNIX-y command line and server tools I turn to <a href="http://mxcl.github.com/homebrew/" target="_blank">Homebrew</a>, the tool set that <em>&#8220;installs the stuff you need that Apple didn&#8217;t&#8221;</em>. Homebrew supports installing both PostgreSQL and PostGIS but a bit of background research showed that installing these on Lion and on Mountain Lion could be problematic. A bit of further research soon turned up <a href="http://postgresapp.com/" target="_blank">Postgres.app</a>, which claims to be <em>&#8220;the easiest way to run PostgreSQL on the Mac&#8221;</em>. Postgres.app is a single shot installer which wraps PostgreSQL and PostGIS into an easy to install and run self contained environment.</p>

  <p>I&#8217;m a big fan of this approach to a software development environment. All of the stuff I&#8217;ve put up on GitHub and on WordPress.org has been written using <a href="http://mamp.info/en/index.html" target="_blank">MAMP</a>, the single shot installer which wraps up Apache, MySQL and PHP on the Mac so Postgres.app gave instant appeal to me. So, download, install, start.</p>
  <p>Next I found an OSM map extract of Tanzania courtesy of <a href="http://download.geofabrik.de/openstreetmap/africa/" target="_blank">GeoFabrik</a>, which I also downloaded. Now to load the map into PostgreSQL. I made sure my shell&#8217;s <code>PATH</code> pointed to the command line tools provided by Postgres.app by prepending <code>/Applications/Postgres.app/Contents/MacOS/bin</code> to the <code>PATH</code> defined in my <code>.bash_profile</code>, ran <code>psql</code> and created a database called <code>tanzania</code>. So far so good.</p>
  <pre class="bash">
  $ psql
  psql (9.2.2)
  Type "help" for help.

  gary=# CREATE DATABASE tanzania;
  CREATE DATABASE
  gary=# \q
  </pre>
  <p>To load the map into the database I had a choice of two command line tools; <a href="http://imposm.org/" target="_blank">Imposm</a> or <a href="http://wiki.openstreetmap.org/wiki/Osm2pgsql" target="_blank">osm2pgsql</a>. The latter of the two seemed to work out of the box according to the documentation so I used Homebrew to install this tool.</p>
  <pre class="bash">
  $ brew install osm2pgsql
  </pre>
  <p>Now to load the map &#8230;</p>
  <pre class="bash">

  </pre>
  <p>The lack of the <code>AddGeometryColumn</code> function was the clue here. Whilst Postgres.app may come with PostGIS, my custom database was lacking all the PostGIS functionality. So I deleted my initial database and tried to recreate it with the <code>template_postgis</code> template, which also failed.</p>
  <pre class="bash">
  $ psql
  psql (9.2.2)

  <p><strong><em>Updated 24.12.12</em></strong></p>
  <p>As Regina correctly pointed out in the comments, I didn&#8217;t really need to go through the manual process of loading the PostGIS template, the <code>create extension postgis</code> command in <code>psql</code> would have done this for me much quicker and elegantly, reducing the commands to setup my database to just two statements &#8230;</p>
  <pre class="bash">
  $ psql
  psql (9.2.2)
  Type "help" for help.

  gary=# CREATE DATABASE tanzania;

  </pre>
  <p>&#8230; simple when you know how.</p>
  <p><del datetime="2012-12-24T11:22:06+00:00">So I needed to create the <code>template_postgis</code> database from scratch, loading in the <code>postgis.sql</code> and <code>spatial_ref_sys.sql</code> SQL files and then recreate my custom database, based on the template contained in the <code>template_postgis</code> database. The PostGIS SQL files are supplied as part of Postgres.app, if you know where to look for them; you&#8217;ll find them inside the app&#8217;s container in <code>/Applications/Postgres.app/Contents/MacOS/share/contrib/postgis-2.0</code>.<br />

  <p>One final gotcha awaited though. Restarting Postgres.app later that day made psql fail with an error.</p>
  <pre class="bash">
  $ psql
  psql: could not connect to server: No such file or directory
  	Is the server running locally and accepting
  	connections on Unix domain socket "/tmp/.s.PGSQL.5432"?
  </pre>
  <p>Although Postgres.app was running, it looked like the server wasn&#8217;t. Checking the system error logs via Console.app showed me that my newly populated database was running out of shared memory.</p>
  <pre class="bash">

  <p>Thankfully this is a <a href="http://benscheirman.com/2011/04/increasing-shared-memory-for-postgres-on-os-x" target="_blank">known problem</a>; PostgreSQL is really a server application, not a laptop application. The default Mac configuration isn&#8217;t enough to support a medium sized PostgreSQL database, but adding the following configuration settings to <code>/etc/sysctl.conf</code>, creating it via <code>sudo</code> if it doesn&#8217;t already exist and rebooting solved that final problem.</p>

  <p>I now have a working PostgreSQL and PostGIS install, with a map loaded, which TileMill can access. Now all I need to do is learn Carto and actually make the map I originally set out to do &#8230; another learning journey has started.</p>

  <p>Warning. This post contains a sweeping generalisation. Yes, I know that Places are not just part of today&#8217;s digital maps; see the <a href="https://twitter.com/cageyjames" target="_blank">James Fee</a> and <a href="https://twitter.com/twbell" target="_blank">Tyler Bell</a> hangout <em><a href="http://vtny.org/kr" target="_blank">The One Where Tyler Bell Defines Big Data</a></em> as a proof point. But for the sake of this post, just assume that Places and maps are synonymous.</p>
  <p>It&#8217;s never been easier to make a map. Correction. It&#8217;s never been easier to contribute to a map. Today we seem to be <del datetime="2012-09-11T05:01:38+00:00">making</del>contributing to maps everywhere, even underground, or should I say Underground?</p>
  <p>To <del datetime="2012-09-11T05:01:38+00:00">make</del>contribute to a map, you used to have to be a professional map maker, with easy access to an arsenal of surveying or an industrial grade GPS.</p>
  <p>Then came the notion of community mapping. Be it <a href="http://www.openstreetmap.org/" target="_blank">OpenStreetMap</a>, Navteq&#8217;s and Nokia&#8217;s <a href="http://blog.maps.nokia.com/maps-nokia-com/introducing-nokia-map-creator" target="_blank">Map Creator</a> or Google&#8217;s <a href="http://www.google.com/mapmaker" target="_blank">Map Maker</a>, anyone armed with a GPS enabled smartphone, hell, anyone without a GPS, could help make a map.</p>

  <p>And now it seems, all you need to do to help make a map is to be somewhere unmapped with some form of internet access, be it a 3G or 4G cellular data connection, or a wifi connection. As part of the London 2012 Olympic Games, some London Underground stations (finally) got wifi access and sure enough, where wifi goes, so does mapping, even platforms on the London Underground.</p>

  <p>If you&#8217;re an avid Foursquare user you can already display your last checkin, visualised on a map, in the sidebar of your WordPress powered site with the <a href="http://wordpress.org/extend/plugins/wp-quadratum/" target="_blank">WP Quadratum</a> plugin. Foursquare, checkins and maps &#8230; what more could you ask for? Maybe the answer is <em>more maps</em>.</p>
  <p>Version 1.1 of the WP Quadratum plugin, which went live this morning, now has added maps. The previous versions of the plugin used <a href="http://maps.nokia.com" target="_blank">Nokia&#8217;s maps</a>, because I work for Nokia&#8217;s Location &#038; Commerce group and I wanted to use the maps that I work on. But if Nokia&#8217;s maps aren&#8217;t the maps for you then how about <a href="https://maps.google.com" target="_blank">Google&#8217;s</a>, or maybe <a href="http://cloudmade.com" target="_blank">CloudMade&#8217;s</a> <a href="http://www.openstreetmap.org" target="_blank">OpenStreetMap</a> maps or perhaps <a href="http://openlayers.org" target="_blank">OpenLayers&#8217;</a> OpenStreetMap maps.</p>

  <p>Thanks to the <a href="http://mapstraction.com" target="_blank">Mapstraction</a> JavaScript mapping API, WP Quadratum now allows you to choose which mapping provider you&#8217;d like to see your checkins appear on. And if you don&#8217;t want a map on the sidebar of your site, you can embed the checkin map in any post or page with the plugin&#8217;s shortcode too.</p>
  <p>As usual, the plugin is free to download and use, either from the official <a href="http://wordpress.org/extend/plugins/wp-quadratum/" target="_blank">WordPress plugin repository</a> or from <a href="https://github.com/vicchi/wp-quadratum/" target="_blank">GitHub</a>.</p>
  <p>As a fully paid up and self confessed map geek I may be somewhat biased but surely most things can be improved with the simple addition of more maps.</p>

  <p>Then along comes an eye candy map wallpaper app for my MacBook Pro and all pejoratives are instantly replaced with superlatives. Yes, this is eye candy. Yes, this is map wallpaper. But in this case the geographical context is spot on and it&#8217;s definitely eye catching without being superficial in any way.</p>

  <p>The man behind this wonderful piece of geolocated satellite imagery is <a href="https://twitter.com/#!/tomtaylor" target="_blank">Tom Taylor</a>, who has previously blown my mind with his <a href="http://boundaries.tomtaylor.co.uk/" target="_blank">Boundaries</a> visualisation of how London&#8217;s neighbourhoods are perceived by way of Flickr&#8217;s Alpha shape files.</p>
  <p>The app is <a href="http://satelliteeyes.tomtaylor.co.uk/" target="_blank">Satellite Eyes</a> which, once installed on your Mac (sorry Windows and Linux users, you can&#8217;t come to the party), hooks into the geolocation functionality built into the operating system and pulls down Bing&#8217;s satellite imagery and uses it for your wallpaper, centred around your current location, such as where I live in the wilds of South West London.</p>

  <p>Move around a city with your laptop moving with you and the imagery updates itself. Yesterday morning I was in London&#8217;s Soho Square and sure enough, my laptop knew this and showed me, together with an overhead view of the construction sites for London&#8217;s <a href="http://www.crossrail.co.uk/" target="_blank">CrossRail</a> project.</p>
  <p>Map wallpaper in the truest sense of the word. What isn&#8217;t there to like about this?</p>

  <p>Firstly, the UK&#8217;s Daily Telegraph, a &#8220;<em>quality broadsheet</em>&#8221; seems to have just discovered that today&#8217;s digital maps also have satellite imagery. It&#8217;s not entirely clear how this is news, let alone current news. Navteq has had satellite imagery as part of its&#8217; maps since the mid 1980&#8217;s and Google has also included satellite imagery in Google Maps since the mid 2000&#8217;s. But linked to Apple&#8217;s recent acquisition of 3D imagery specialists C3, we&#8217;re told to anticipate a &#8220;<em><a href="http://www.telegraph.co.uk/technology/apple/9323388/Apple-spy-planes-to-film-homes-from-the-air.html" target="_blank">private fleet of aeroplanes equipped with military standard cameras to produce 3D maps so accurate they could film people in their homes through skylights</a></em>&#8220;. The middle market tabloid Daily Mail has also picked up on this story, running with the headline &#8220;<em><a href="http://www.dailymail.co.uk/debate/article-2157353/Apple-Google-Spies-sky-regulate.html?ito=feeds-newsxml" target="_blank">Spies in the sky that no one will regulate</a></em>&#8220;.</p>

  <p>Yet only in January of this year, the Daily Mail published a series of extremely detailed aerial images under the headline &#8220;<em><a href="http://www.dailymail.co.uk/news/article-2085752/Eye-sky-The-pretty-patterns-housing-developments-world.html" target="_blank">A nosey parker&#8217;s dream; Stunning aerial photographs show what&#8217;s going on in the world&#8217;s back gardens</a></em>&#8220;. Apart from the slightly sensationalistic &#8220;<em>nosey parker</em>&#8221; reference, this six month old article seems to positively luxuriate in the high altitude photography. As Google&#8217;s Ed Parsons pithily points out, this is another case of &#8220;<em><a href="https://twitter.com/edparsons/status/212097782603976704">editorial integrity by the Daily Mail</a></em>&#8220;.</p>

  <p>Meanwhile, digital mapping provider TomTom, who acquired Tele Atlas in 2008 has produced what&#8217;s often described as a <a href="http://en.wikipedia.org/wiki/Fear,_uncertainty_and_doubt" target="_blank">FUD</a> piece (fear, uncertainty and doubt) on <a href="http://www.tomtom.com/en_gb/licensing/newsletter/201205/didyouknow/" target="_blank">digital map data produced by OpenStreepMap</a>. The article starts off well</p>
  <blockquote><p>&#8220;The concept of open source mapping is a very exciting one. As various technologies become more accessible, volunteer mappers can collect information and collaborate to produce shared maps. They’re cheap to make, licensing is often free or very low-cost, and users benefit from the knowledge of a large community of updaters.&#8221;</p></blockquote>
  <p>So far, so good. OSM has been gaining a lot of traction and attention over recent months as Nestoria, Apple (for iPhoto on the iPad), Wikipedia and Foursquare all adopted OSM maps to power their spatial visualisations. But not, it&#8217;s worth noting, to power turn-by-turn navigation applications. But according to TomTom, all is not well with this.</p>
  <blockquote><p>Despite the positives, recent studies have highlighted some major drawbacks of open source mapping, specifically with regard to safety, accuracy and reliability. In one particular instance, a leading open source map was compared against a professional TomTom map, and shown to have a third less residential road coverage and 16% less basic map attributes such as street names. Worse still, it blended pedestrian and car map geometry, and included &#8216;a high number of fields and forest trails&#8217; classified as roads.</p></blockquote>
  <p>Interestingly, this view from TomTom clashes somewhat with a 2011 study comparing TomTom and OpenStreetMap in Germany which concluded that</p>
  <blockquote><p>&#8220;With a relative completeness comparison between the OSM database and TomTom&#8217;s commercial dataset, we proved that OSM provides 27% more data within Germany with regard to the total street network and route information for pedestrians.&#8221;</p></blockquote>
  <p>So why highlight the difference between OSM and TomTom data now? As TechDirt notes in its&#8217; <a href="http://www.techdirt.com/articles/20120529/07503819113/tomtom-kicks-off-fud-campaign-against-dangerous-open-source-mapping.shtml" target="_blank">commentary on this topic</a></p>
  <blockquote><p>&#8220;The fact that TomTom has chosen to highlight this current deficiency in OpenStreetMap shows two things. First, that it is watching the open source alternative very closely, and secondly, that it is sufficiently worried by what it sees to start sowing some FUD in people&#8217;s minds. But as history has shown with both open source server software and open source encyclopaedias, once vendors of proprietary systems adopt such a tactic against up-and-coming free rivals, it&#8217;s a clear sign that it&#8217;s already too late to do anything about it, and that their days of undisputed dominance are numbered.&#8221;</p></blockquote>
  <p>Whether that&#8217;s a fair and accurate summary of this remains to be seen, but what this does prove it that just as I&#8217;ve been saying for the last two years that there is no one single authoriative source of Place data and there probably never will, so there is no one single authoriative map and likewise, there probably never will.</p>
  <p>Without meaning to trivialise the adoption of OSM by Wikipedia, Foursquare et al, these maps are what might be termed map wallpaper; great for showing geographical and geospatial context for information. The high level of accuracy and internal data attributes needed to produce a turn-by-turn navigation system simply isn&#8217;t needed here. Which makes TomTom&#8217;s evaluation of OSM all the more puzzling.</p>

  <p>Judging by comments to this blog post, on Twitter and on Google Plus, the consensus seems to be that yes, Apple is using OSM data from 2010 outside of the US; inside of the US it&#8217;s (probably) TIGER data and no, there doesn&#8217;t seem to be attribution and Apple may well be getting a communiqué from OSM to that effect.

  </ul>
  <p>&#8230; and now, back to the original post.</p>
  <p>We live in a world dominated by and surrounded by brands. One of the hallmarks of a successful brand is whether it&#8217;s able to be immediately recognised as that brand, without necessarily looking too deeply for a brand label. Look at a car and you&#8217;ll probably be able to tell whether it&#8217;s a Ford or not. Look at a laptop and you&#8217;ll probably be able to tell whether it&#8217;s Apple&#8217;s or one of those faceless, grey, consumer models. Look at an espresso cup and you&#8217;ll probably be able to tell whether it&#8217;s got coffee from Illy in it.</p>
  <p>As it is in the real, offline world, so it is in the digital, online world and nowhere is this more prevalent than in the world of digital maps. Each mapping provider has an immediately recognisable look, feel and style to it. You can tell whether the map is from Nokia or NAVTEQ, from Google, from Mapquest or from OpenStreetMap. Now granted, a digital map is the product of lots of data sources but the map&#8217;s style is unique; although OpenStreetMap&#8217;s style is almost the exception as there&#8217;s several styles you can use.</p>
  <p>Ever since the launch of the original iPhone, for Apple that look and feel of their maps have been Google&#8217;s. Even before you look to the bottom right hand corner of the map and see the Google logo you&#8217;ll know it&#8217;s a Google map. There&#8217;s also been lots of rumours that with Apple&#8217;s acquisitions in the mapping space, C3 and Placebase to name but a few, it wouldn&#8217;t be too long before Apple had their own map.</p>

  <p>Maybe that time has now come, for iPhoto on iOS at least. Take a look at the screen grabs above. These maps aren&#8217;t, at least at face value, Google&#8217;s. The map style isn&#8217;t Google&#8217;s and even more interestingly, there&#8217;s no immediately apparent copyright or brand notice anywhere on the map. Is this Apple&#8217;s new map or is it another map provider&#8217;s under a license that doesn&#8217;t need branding?</p>

  <p>In web and location circles, much has been made of Foursquare&#8217;s recent &#8220;<em><a href="http://blog.foursquare.com/2012/02/29/foursquare-is-joining-the-openstreetmap-movement-say-hi-to-pretty-new-maps/">little announcement</a></em>&#8221; of the location based, check-in, company&#8217;s <a href="http://thenextweb.com/insider/2012/02/29/foursquare-ditches-google-maps-for-mapbox-and-openstreetmaps/">decision to oust Google Maps</a> and instead to go with <a href="http://www.openstreetmap.org/">OpenStreetMap</a> data, by way of <a href="http://mapbox.com/">MapBox</a>.</p>
  <p>From reading a lot of the coverage you&#8217;d be forgiven for thinking that Foursquare has completely severed ties with Google&#8217;s mapping APIs, but this isn&#8217;t quite the story. As <a href="http://www.readwriteweb.com/archives/foursquare_dumps_google_goes_open-source_for_maps.php">ReadWriteWeb notes in the last paragraph of its coverage</a>, &#8220;<em>Foursquare&#8217;s iPhone and Android apps won&#8217;t be affected</em>&#8221; as the move is for Foursquare&#8217;s home on the web, <a href="http://foursquare.com">foursquare.com</a>, only.</p>
  <a href="http://www.vicchi.org/wp-content/uploads/2012/03/Foursquare.png"><img data-attachment-id="2346" data-permalink="https://www.vicchi.org/2012/03/03/foursquare-goes-with-openstreetmap-on-the-web/foursquare/" data-orig-file="https://www.vicchi.org/wp-content/uploads/2012/03/Foursquare.png" data-orig-size="1160,937" 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="Foursquare" data-image-description="" data-medium-file="https://www.vicchi.org/wp-content/uploads/2012/03/Foursquare-300x242.png" data-large-file="https://www.vicchi.org/wp-content/uploads/2012/03/Foursquare-1024x827.png" class="aligncenter size-full wp-image-2346" title="Foursquare" src="http://www.vicchi.org/wp-content/uploads/2012/03/Foursquare.png" alt="" width="1160" height="937" srcset="https://www.vicchi.org/wp-content/uploads/2012/03/Foursquare.png 1160w, https://www.vicchi.org/wp-content/uploads/2012/03/Foursquare-300x242.png 300w, https://www.vicchi.org/wp-content/uploads/2012/03/Foursquare-1024x827.png 1024w" sizes="(max-width: 1160px) 100vw, 1160px" /></a>
  <p>Indeed, the current set of <a href="https://foursquare.com/apps/">Foursquare smartphone apps</a> continue to use a variety of mapping platforms. On Android and on iOS, it&#8217;s still Google Maps, not unsurprisingly given Android is effectively a Google mobile OS, and Google is still Apple&#8217;s mapping platform of choice, <a href="http://arstechnica.com/apple/news/2011/10/apple-now-has-third-piece-of-mapping-puzzle-but-whats-the-full-picture.ars">for now at least</a>.</p>
  <p>On Blackberry it&#8217;s also business as usual for Google Maps, whilst on Symbian, it&#8217;s Nokia&#8217;s mapping platform and on Windows Phone 7 it&#8217;s (<a href="http://www.theverge.com/2012/2/28/2831207/bing-maps-nokia-map-design">currently</a>) the Bing mapping platform.</p>
  <p>So while this move is great news for both the OpenStreetMap community and for MapBox and, as ReadWriteWeb notes, &#8220;<em>when you use Foursquare Explore on the Web to search for places, you&#8217;ll be taking eyeballs away from Google</em>&#8220;, this is a move that affects Foursquare&#8217;s web presence only, not their mobile apps. Given that in order to actually use Foursquare effectively, in other words, to check-in, you need to be on a smartphone, I wonder how many eyeballs will actually be taken away from Google. Furthermore, whilst those in the location industry are looking at this keenly, I have to wonder how many users of Foursquare will actually notice the change on the web.</p>
  <p>For Foursquare on the web this is probably a smart move and for most users of the Foursquare website, OpenStreetMap data is, as Muki Haklay noted in a paper published in 20101, &#8220;<em><a href="http://www.envplan.com/abstract.cgi?id=b35097">good enough</a></em>&#8220;.</p>
  <p>But not good enough apparently for some Foursquare users, who are fairly outspoken about blank or incomplete maps on the <a href="http://blog.foursquare.com/2012/02/29/foursquare-is-joining-the-openstreetmap-movement-say-hi-to-pretty-new-maps/#comments">comments to Foursquare&#8217;s announcement</a> blog post.</p>
  <p>It would be good to think that Foursquare&#8217;s use of OpenStreetMap data will encourage their users to contribute to the underlying open spatial data set that is OSM; after all, all you really need is a GPS device, which is what most smartphones are these days. The optimist in me hopes that this will be the case. The pessimist in me, or maybe it&#8217;s the realist in me, tempers that hope with the realisation that Foursquare still makes the address of a new Place optional, that a geocode from a GPS device probably isn&#8217;t enough and that most Foursquare users neither know or care about the underlying map, caring far more about getting to the top of the leaderboard, becoming Mayor and earning badges.</p>
  <p>Time alone will tell whether my optimistic side is right.</p>

  <p>The first computer I used at work was powerful for its day (though pitifully underpowered compared to the phone that&#8217;s sitting in my pocket at the moment) but was somewhat unfriendly by today&#8217;s standards. You sat down at a terminal (not a PC, they hadn&#8217;t been invented) and were presented with a command line prompt that said &#8220;<em>Username:</em>&#8220;, pass that barrier to entry and it said &#8220;<em>Password:</em>&#8220;. Armed with the right combination of username and password you would be rewarded with a flashing cursor preceded by a dollar sign as a prompt &#8230; <em>$</em>. If you wanted help you couldn&#8217;t browse the web (it hadn&#8217;t been invented) nor ask in a mailing list (the Internet was in its early days and you probably didn&#8217;t have access). Instead you consulted the big, heavy, ring bound, bright orange documentation set; these were the heady days of DEC and VAX/VMS.</p>
  <p>The computer I&#8217;m writing this on still needs a username and password but is easy to use, graphical, intuitive and comes with multiple web sites, discussion and documentation sites and mailing lists to ask questions in. But to get the most of today&#8217;s computers you still need a book sometimes, which is why David Pogue&#8217;s <a href="http://oreilly.com/catalog/9780596153281/">Mac OS X: The Missing Manual</a> is still one of the most well thumbed books I have, 8 years and multiple editions later. There&#8217;s a version for <a href="http://oreilly.com/catalog/9780596806392/">Windows</a> too.</p>
  <p>So what does this have to do with OpenStreetMap? Bear with me &#8230; there are parallels to be drawn.</p>

  <p>OpenStreetMap is easy to use, graphical (on the <a href="http://www.openstreetmap.org/">website</a>), comes with multiple discussion and <a href="http://wiki.openstreetmap.org/wiki/Main_Page">documentation</a> sites and well supported <a href="http://wiki.openstreetmap.org/wiki/Mailing_List">mailing lists</a>; you can always find the answer to your question. But sometimes you don&#8217;t know what the question is. Sometimes you just want to read a <em>book</em>.</p>
  <p><a href="http://www.openstreetmap.info/">OpenStreetMap: Using and Enhancing The Free Map Of The World</a> is that book &#8230; consider it the Missing Manual if you will.</p>
  <p>Originally written in German by mailing list stalwarts Frederik Ramm and Jochen Topf in 2008 (names which will be familiar to anyone who&#8217;s spent any time on the OSM mailing lists), the book was translated into English with Steve Chilton (chair of the UK&#8217;s <a href="http://www.soc.org.uk/index.htm">Society of Cartographers</a>) towards the end of 2010. A translation would be impressive enough but the English version also comes with expanded sections and all of the content, examples and illustrations have been revisited, revised and updated.</p>
  <p>Whether you&#8217;re an OSM expert or you just want to see how one of the largest voluntary, crowd sourced projects on the face of the Internet works this is a worthy and valuable addition to your bookshelf. While no OSM expert I considered myself fairly well versed in how to use OpenStreetMap. Reading the book was a salient lesson on just how much I didn&#8217;t know; the section on GPS was an education in itself.</p>
  <p>The book also provides a well written and easy to understand explanation of what you can and what you can&#8217;t do with OSM&#8217;s wealth of geographic data and answers so many of the questions on data licensing that crop up again and again in conversations around OSM and on the mailing lists.</p>
  <p>As a written work, the OpenStreetMap book works on multiple levels. You can dip into it, select the parts that interest you, get distracted by reading about stuff you didn&#8217;t think you&#8217;d want to know or you can read it from cover to cover.</p>
  <ul>
  <li>If you want to contribute data to OpenStreetMap &#8230; this is the book for you</li>
  <li>If you want to use OpenStreetMap data to create maps &#8230; this is the book for you</li>
  <li>If you want to integrate OpenStreetMap data into a web site &#8230; this is the book for you</li>
  <li>If you consider yourself as a fully paid up geo nerd who lives and breathes open data &#8230; this is the book for you. No &#8230; really</li>
  </ul>
  <p>One final thought; the old adage about the Internet being an information hose pipe holds true where OpenStreetMap is concerned. The volume of information and data is simply staggering. You can find your way through all of this information by yourself. Or you can just read a well written, well thought out book instead. Even in today&#8217;s online world there&#8217;s still a place for the feeling you get from holding a book in your hands and leafing back and forwards through the pages. My copy of this book is still reasonably pristine, despite being hauled on and off planes and read from cover to cover. I can&#8217;t guarantee it&#8217;ll stay that way for long.</p>

  <p>For Londoners this will probably come as no surprise, but this time around, the BBC are crowd-sourcing a map of station closures, services affected and the knock on impact to other forms of London public transport, using publicly submitted reports and media in addition to reporters on the street. It seems natural enough that this will be visualised on a map and in tonight&#8217;s BBC London News, it was plainly evident that the BBC are using OpenStreetMap as the underlying map tiles for the visualisation.</p>

  Yesterday I backed a Kickstarter project called Mapwheel, I think it’s a really cool idea. They let you design a custom “toposcope” or map wheel showing the direction and distance of places of interest from the location where you live (or any other location you choose). You can choose various materials (wood or metal) and customize the design in various ways.

  FOSS4G NA was awesome
  There were way more female presenters than at previous events
  Mapbox was everywhere
  Boundless wasn’t
  Lots of new developments on vector tiles, including several efforts from companies other than Mapbox – even some promised from Esri!

  I spent the past weekend in Washington DC for State of the Map (SotM) US, the OpenStreetMap conference. It ended up selling out, with around 500 attendees, making it the largest OpenStreetMap event yet. As with previous SotM events I’ve attended (the last one being in Denver in 2011), I found it very enjoyable and interesting, and there was great energy about it as always, much more than

  Just a quick post to mention that Ubisense is looking for a couple of people to join our geospatial team in the US. We've been growing rapidly and have a lot of exciting things going on. First is a Senior Project Manager.  Ideally we'd like someone with experience managing complex geospatial projects in utilities and/or telecommunications companies, and preferably but not necessarily experience

  A couple of months ago I gave a talk at the monthly OpenStreetMap meetup in Denver and I decided to try crowdsourcing the content (in the best OpenStreetMap tradition), and it worked out very well. I received a good amount of interesting content from several folks (thanks everyone!). I rashly agreed to do a keynote at the upcoming State of the Map conference in Denver (rashly since I'm chairing

That event had a profound impact on my perspective on the geospatial industry, and on the software platforms I've chosen to implement geospatial applications on since then. And it has saved my companies a lot

  Apple rather belatedly issued a Q&A on the whole "LocationGate" saga. This confirms what I said about the data being a cache of cell tower and wifi locations. The fact that this was kept for up to a year was a bug. Within the next few weeks they will reduce this to 7 days, they will not back up the cache any longer, and they will turn off the cache when you turn location services off, which

It is an arid desert, with very sparse population &#8211; about 4000 people who live in <a href="https://en.wikipedia.org/wiki/Hevel_Eilot_Regional_Council">communal settlements &#8211; mostly kibbutzim</a> in an area of 2650 sq km (about the area of Luxembourg. This is a very challenging place for Western-style human habitation, in an area with a fragile desert ecosystem. The region and the <a href="https://en.wikipedia.org/wiki/Arava_Institute_for_Environmental_Studies">Arava Institute </a>at the centre of it, provided the stage for a workshop on <a href="https://www.ecologyandsociety.org/vol11/iss2/art13/">Long-Term Socio-Ecological Research (LTSER)</a> network with participants from the European network and supported by the <a href="http://www.lter-europe.net/elter">eLTER H2020 project</a>. LTER and LTSER are placed-based research activities that are led from the ecological perspective, with the latter integrating social aspects as an integral part of its inquiry and research framework.</p>
  <p>The workshop run from 4-8 March on location, which allowed the immersion into the issues of the place, as well as exchanging experiences and views across the different &#8220;platforms&#8221; (the coordination bodies for the different sites that are used for LTSER research). While the people who are involved in the network were mostly familiar with one another, <strong>I was the external guest</strong> &#8211; invited to provide some training and insight into the way citizen science can be used in this type of research.</p>
  <p>Its been over 21 years since I&#8217;ve been in this place &#8211; which I visited several times from my childhood to my late 20s. With a long experience of living in the UK, I felt like an outsider-insider &#8211; I can understand many of the cultural aspects while, at the same time, bringing my thinking and practice that is shaped through my work at UCL over this period. Also in disciplinary terms, I was outsider-insider &#8211; I&#8217;m interested in ecology, and with citizen science, linked to many people and activities in this area of research &#8211; however, I&#8217;m not an ecologist (leaving aside what exactly is my discipline). Because of that, I am aware of their framework, research questions, and issues (e.g. limited funding and marginalisation in science and research policy) which helped me in understanding the discussion and participating in it.</p>
  <p>Visiting the area, discussing the social and ecological aspects, and progressing on a range of concepts, brought up several reflections that I&#8217;m outlining here:</p>

It was quite telling that the head of the region, <a href="http://www.adssc.org/en/reserchers/hanan-ginat">who is an active scientist</a>, was pointing out that they want to have progressive development, and not exactly sustainable development. As we visited and travelled through the area, the challenges of achieving sustainability &#8211; with a wish for limited demographic growth and economic development that will ensure the high quality of life that the communities carve in a hostile environment can continue. This means attracting younger people who want to be part of the specific kibbutz community (the average age in the current settlement is quite high); bringing in commercial activities that match the characteristics of the area without altering them hugely &#8211; such as renewable energy activities (the area is already receiving 70% of energy from renewable energy during the day), agriculture (the area is a large producer of <a href="https://en.wikipedia.org/wiki/Medjool">Medjool dates</a>), and tourism (a new airport is about to be finished for flights from Europe); and all this while paying attention to the environmental and natural aspects of the area.</p>
  <p>Second, <strong>the importance of cultural shaping of human-environment relationship in the area</strong>. The social organisation, the focus on agriculture (in addition to the dates there is an important milk dairy in ), and a strong belief in the power of technology to offer solutions to emerging problems stood out as major drivers of the way things happen. Each Kibbutz have a specific culture, which influences its social and operational characteristics so each is making collective decisions according to the specific organisation, and this has an environmental impact &#8211; for example, with the increase in heat due to climate change it must be that Yotveta, with a big herd of milk cows that are maintained in the desert conditions, is facing tougher challenges &#8211; and we heard from Ketura who made the decision not to maintain their herd. The impact here is an increasing use of water to cool the cows, not to mention that need to bring the feed from outside, I&#8217;d guess through Eilat port which is a short drive away. The agriculture is important in both the general ethos of the Kibbutz movement, but also significant economic income &#8211; and at the moment the dates are suitable in terms of the income that they provide. The way technological optimism is integrated into this vision is especially interesting and was pointed out by several participants. Several local presenters (some of them decision makers) mentioned that the region wants to be &#8220;<em><a href="http://www.eilateilot.org/welcome-to-eilat-eilot/">silicon valley of renewable energy</a></em>&#8221; and there is already rapid development of various solar energy schemes in different settlements, a research centre, and the cadaver of <a href="https://en.wikipedia.org/wiki/Better_Place_(company)">Better Place battery replacement station</a>, but clearly nothing on the scale of say, <a href="https://en.wikipedia.org/wiki/Masdar_Institute_of_Science_and_Technology">Masdar Institute</a> or anything similar in terms of the scale and R&amp;D effort, so it is not clear what is standing behind this phrase. It seems more like a beacon of energy independence of some sort, and the provision of energy to the nearby city of Eilat as a source of income. The local presentation and discussions show a strong &#8220;frontier&#8221; conceptualisation of a personal and collective role, and this comes first in term of the relationship with the environment. The result is odd &#8211; organic palm dates which are planted next to fragile sand dunes, and with issues with waste management&#8230;</p>

The area is perfect for citizen science activities &#8211; it got a highly educated population, large areas of nature reserves, very good mobile connectivity even off the roads, and environmental awareness (even if actions are contradictory). It is also a critical place for migrating bird, and there is a small visitors and research park near Eilat. At least from the point of view of LTSER, there&#8217;s a potential for a range of activities that can cater for local and for tourists.</p>
  <p>Fourth, it was interesting to have <strong>discussions about citizen science that moved well beyond <a href="https://povesham.wordpress.com/2018/02/09/citizen-science-scientific-crowdsourcing-week-5-data-quality/">concerns over data quality</a></strong> (although I did have some of those too &#8211; as expected!). Amongst ecologists, the term citizen science is familiar, though not the full range of possibilities and issues. There were many questions about potential cross sites projects, recruitment and maintaining work with participants, creating new projects, and even using the results from citizen science in policy processes and gaining legitimacy.</p>
  <p>Fifth, and something that I think worth exploring further &#8211; I couldn&#8217;t escape the thought that<strong> it will be very interesting to compare the kibbutz social and cultural organisation over time with open source and open knowledge projects</strong>. A concern that we heard through the visit is about the need for demographic growth but with very specific and testing conditions for anyone who wants to join &#8211; beyond the challenging environmental conditions. There is a fascinating mix of strong ideological motivations (settling the desert, leaving in communal settings, doing agriculture in the desert) with actions that are about comfort and quality of life, and as a result, concern about the ageing of the core population many of them from the founding generation. I can see parallels with open knowledge projects such as  OpenStreetMap, or citizen science projects, where you hear two contradictory statements at one &#8211; a wish to bring more people on, combined with a strong demand for commitment, and practical barriers to entry, which as a result create a stable core community which slowly age&#8230;</p>
  <p>The workshop was summarised graphically by Aya Auerbach, in the following way.</p>

To achieve that, we&#8217;ve approached <a href="http://www.ubiquitypress.com/">Ubiquity Press, who specialise in open access academic publishing</a>, and set a process of organising the writing of short and accessible chapters from across the spectrum of research interests and topics that are covered by members of the network. <strong><a href="http://cartography.tuwien.ac.at/haosheng-huang/">Dr Haosheng Huang (TU Wien)</a></strong> volunteered to assist with the editing and management of the process. The chapters then went through internal peer review, and another cycle of peer review following Ubiquity Press own process, so it is thoroughly checked!</p>
  <p>The book includes 31 chapters with relevant information about application of VGI and citizen science, management of data, examples of projects, and high level concepts in this area.</p>
  <p><strong><a href="http://www.ubiquitypress.com/site/books/10.5334/bax/">The book is now available for download here</a>. </strong>Here is the description of the book:</p>
  <blockquote><p>This book focuses on the study of the remarkable new source of geographic information that has become available in the form of user-generated content accessible over the Internet through mobile and Web applications. The exploitation, integration and application of these sources, termed volunteered geographic information (VGI) or crowdsourced geographic information (CGI), offer scientists an unprecedented opportunity to conduct research on a variety of topics at multiple scales and for diversified objectives.<br />
  The Handbook is organized in five parts, addressing the fundamental questions:</p>
  <ul>
  <li>What motivates citizens to provide such information in the public domain, and what factors govern/predict its validity?</li>
  <li>What methods might be used to validate such information?</li>
  <li>Can VGI be framed within the larger domain of sensor networks, in which inert and static sensors are replaced or combined by intelligent and mobile humans equipped with sensing devices?</li>
  <li>What limitations are imposed on VGI by differential access to broadband Internet, mobile phones, and other communication technologies, and by concerns over privacy?</li>
  <li>How do VGI and crowdsourcing enable innovation applications to benefit human society?</li>
  </ul>
  <p>Chapters examine how crowdsourcing techniques and methods, and the VGI phenomenon, have motivated a multidisciplinary research community to identify both fields of applications and quality criteria depending on the use of VGI. Besides harvesting tools and storage of these data, research has paid remarkable attention to these information resources, in an age when information and participation is one of the most important drivers of development.<br />
  The collection opens questions and points to new research directions in addition to the findings that each of the authors demonstrates. Despite rapid progress in VGI research, this Handbook also shows that there are technical, social, political and methodological challenges that require further studies and research</p></blockquote>

It seems that the SDGs are very much in the front of the mind of the international organisations who are part of the Eye on Earth alliance, although other organisations, companies and researchers who are coming with more technical focus (e.g. Big Data or Remote Sensing) are less aware of them &#8211; at least in terms of referring to them in their presentations during the summit.</p>
  <p>Beyond the SDGs, two overarching tensions emerged throughout the presentations and discussions &#8211; and both are challenging. They are the tensions between <strong>abundance and scarcity</strong>, and between <strong>emotions and rationality</strong>. Let&#8217;s look at them in turn.</p>
  <p><strong>Abundance and scarcity came up again and agin</strong>. On the data side, the themes of &#8216;data revolution&#8217;<b>, </b>more satellite information, crowdsourcing from many thousands of weather observers and the creation of more sources of information (e.g. Environmental Democracy Index) are all examples for abundance in the amount of available data and information. At the same time, this was contrasted with the scarcity in the real world (e.g species extinction, health of mangroves), scarcity of actionable knowledge, and scarcity with ecologists with computing skills. Some speakers oscillated between these two ends within few slides or even in the same one. There wasn&#8217;t an easy resolution for this tension, and both ends were presented as challenges.</p>

  <p>With <strong>emotions and scientific rationality</strong>, the story was different. Here the conference was packed with examples that we&#8217;re (finally!) moving away from a simplistic &#8216;<a href="https://en.wikipedia.org/wiki/Information_deficit_model">information deficit model</a>&#8216; that emphasise scientific rationality as the main way to lead a change in policy or public understanding of environmental change. Throughout the summit presenters emphasised the role of mass media communication, art (including live painting development through the summit by GRID-Arendal team), music, visualisation, and story telling as vital ingredients that make information and knowledge relevant and actionable. <strong>Instead of a<a href="http://www.bbc.co.uk/programmes/b01phhy5"> &#8216;Two Cultures&#8217; position</a>, Eye on Earth offered a much more harmonious and collaborative linkage</strong> between these two ways of thinking and feeling.</p>
  <p>Next, and linked to the issue of abundance and scarcity are <strong>costs and funding</strong>. Many talks demonstrated the value of <strong>open data </strong>and the need to provide open, free and accessible information if we want to see environmental information used effectively. Moreover, providing the information with the ability of <strong>analyse or visualise it over the web</strong> was offered as a way to make it more powerful. However, the systems are costly, and although the assessment of the IUCN demonstrated that the investment in environmental datasets is modest compared to other sources (and the same is true for citizen science), <strong>there are no sustainable, consistent and appropriate funding mechanisms</strong>, yet. <strong>Funding infrastructure or networking activities is also challenging</strong>, as funders accept the value, but are not willing to fund them in a sustainable way. More generally, there is an issue about the need to <strong>fund ecological and environmental studies </strong> &#8211; it seem that while &#8216;established science&#8217; is busy with &#8216;Big Science&#8217; &#8211; satellites, Big Data, complex computer modelling &#8211; the work of studying ecosystems in an holistic way is left to <a href="https://povesham.wordpress.com/2015/01/05/diary-of-a-a-citizen-scientist-by-sharman-apt-russell/">small group of dedicated researchers and to volunteers</a>. The urgency ad speed of environmental change demand better funding for these areas and activities.</p>
  <p>This lead us to the issue of <strong>Citizen Science</strong>, for which the good news are that it was mentioned throughout the summit, gaining more prominence than 4 years ago in the first summit (<a href="https://povesham.wordpress.com/2011/12/19/reflection-on-eye-on-earth-summit-2-the-3-eras-of-public-access-to-environmental-information/">were it also received attention</a>). In all plenary sessions, citizen science or corwdsourced geographic information were mentioned at least once, and frequently by several speakers. Example include <a href="http://www.cousteaudivers.org/community/blogpost/project-hermes">Hermes project</a> for recording ocean temperatures, <a href="http://airscapessingapore.datacollider.io/">Airscapes Singapore</a> for urban air quality monitoring, the <a href="http://www.wunderground.com/">Weather Underground</a> of sharing weather information, <a href="http://hotosm.org/projects/malawi_flood_preparedness">Humanitarian OpenStreetMap Team work in Malawi</a>, Kathmandu Living Lab <a href="http://quakemap.org/">response to the earthquake in Nepal</a>, <a href="http://aycm.org/countries/bahrain/">Arab Youth Climate Movement in Bahrain</a> use of iNaturalist to record ecological observations, Jacky Judas <a href="http://wwf.panda.org/about_our_earth/search_wwf_news/?209287/Rare-Dragonfly-Discovered-in-Wadi-Wurayah">work with volunteers to monitor dragonflies</a> in Wadi Wurayah National Park  &#8211; and many more. Also the <a href="http://www.eoesummit.org/news/eye-on-earth-summary-of-outcomes/">summit outcomes</a> document is clear:  &#8220;<strong>The Summit highlighted the role of citizen science groups in supporting governments to fill data gaps</strong>, particularly across the environmental and social dimensions of sustainable development. <strong>Citizen Science was a major focus area within the Summit agenda</strong> and there was general consensus that reporting against SDGs must include citizen science data. To this end, a global coalition of citizen science groups will be established by the relevant actors and the Eye on Earth Alliance will continue to engage citizen science groups so that new data can be generated in areas where gaps are evident. The importance of citizen engagement in decision-making processes was also highlighted. &#8221;</p>
  <p>However, there was ambivalence about it &#8211; should it be seen as an instrument, a tool to produce environmental information or as a mean to get wider awareness and engagement by informed citizens? How best to achieve the multiple goals of citizen science: raising awareness, educating, providing skills well beyond the specific topic of the project, and democratising decision making and participation? It seem to still be the case that the integration of citizen science into day to day operations is challenging for many of the international organisations that are involved in the Eye on Earth alliance.</p>
  <p>Another area of challenging interactions emerged from the <strong>need for wide partnerships</strong> between governments, international organisations, Non-Governmental Organisations (NGOs), companies, start-ups, and even ad-hoc crowds that respond to a specific event or an issue which are afforded by digital and social network. There are very different speeds in implementation and delivery between these bodies, and in some cases there are chasms that need to be explored &#8211; for example, an undercurrent from some technology startups is that governments are irrelevant and in some forms of thinking that &#8216;to move fast and break things&#8217; &#8211; including existing social contracts and practices &#8211; is OK. It was somewhat surprising to hear speakers praising Uber or AirBnB, especially when they came from people who familiar with the need for careful negotiations that take into account wider goals and objectives. <strong>I can see the wish to move things faster &#8211; but to what risks to we bring by breaking things?</strong></p>
  <p>With the discussions about <strong><a href="http://www.unep.org/civil-society/Implementation/Principle10/tabid/105013/Default.aspx">Rio Principle 10</a> </strong>and the new developments in Latin America, the Environmental Democracy Index, and the rest, I became more convinced, as <a href="https://povesham.wordpress.com/2011/12/19/reflection-on-eye-on-earth-summit-2-the-3-eras-of-public-access-to-environmental-information/">I&#8217;ve noted in 2011</a>, that we need to start thinking about adding another right to the three that are included in it (access to environmental information, participation in decision-making, and access to justice), and develop a right to produce environmental information that will be taken seriously by the authorities &#8211; in other words, <strong>a right for citizen science</strong>. I was somewhat surprised by the responses when I raised this point during the <a href="https://povesham.wordpress.com/2015/10/08/eye-on-earth-day-3-morning-enabling-conditions-and-access-to-information-participation-justice/">discussion on Principle 10</a>.</p>
  <p style="text-align:center;"><a href="http://www.iisd.ca/eoesummit/2015/8oct.html"><img class="" src="https://i1.wp.com/www.iisd.ca/eoesummit/2015/images/8oct/DSC_3473.jpg" alt="" /></a> <strong>Final panel</strong> (source: IISD)</p>
  <p>Finally, Eye on Earth was <strong>inclusive and collaborative</strong>, and it was a pleasure to see how open people were to discuss issues and explore new connections, points of view or new ways of thinking about issues. A special point that raised several positive responses was the <strong>gender representation</strong> in such high level international conference with a fairly technical focus (see the image of the closing panel). The composition of the speakers in the summit, and the fact that it was possible to have such level of women representation was fantastic to experience (making one of the male-only panels on the last day odd!). It is also an important lesson for many academic conferences &#8211; if Eye on Earth can, I cannot see a reason why it is not possible elsewhere.</p>

  <p>Considering how long <strong><a href="http://rose.geog.mcgill.ca/">Reneé Sieber  (McGill University)</a></strong> and I know each other, and working in similar areas (participatory GIS, participatory geoweb, open data, socio-technical aspects of GIS, environmental information), I&#8217;m very pleased that a collaborative paper that we developed together is finally published.</p>
  <p>The paper &#8216;<strong><a href="http://onlinelibrary.wiley.com/doi/10.1002/geo2.10/abstract">The epistemology(s) of volunteered geographic information: a critique</a></strong>&#8216; took some time to evolve. We started jotting ideas in late 2011, and slowly developed the paper until it was ready, after several rounds of peer review, for publication in early 2014, but various delays led to its publication only now. What is pleasing is that the long development time did not reduced the paper relevancy &#8211; we hope! (we kept updating it as we went along). Because the paper is looking at philosophical aspects of GIScience, we needed periods of reflection and re-reading to make sure that the whole paper come together, and I&#8217;m pleased with the way ideas are presented and discussed in it. Now that it&#8217;s out, we will need to wait and see how it will be received.</p>
  <p>The abstract of the paper is:</p>
  <p><em>Numerous exegeses have been written about the epistemologies of volunteered geographic information (VGI). We contend that VGI is itself a socially constructed epistemology crafted in the discipline of geography, which when re-examined, does not sit comfortably with either GIScience or critical GIS scholarship. Using insights from Albert Borgmann&#8217;s philosophy of technology we offer a critique that, rather than appreciating the contours of this new form of data, truth appears to derive from traditional analytic views of information found within GIScience. This is assisted by structures that enable VGI to be treated as independent of the process that led to its creation. Allusions to individual emancipation further hamper VGI and problematise participatory practices in mapping/geospatial technologies (e.g. public participation geographic information systems). The paper concludes with implications of this epistemological turn and prescriptions for designing systems and advancing the field to ensure nuanced views of participation within the core conceptualisation of VGI.</em></p>
  <p>The paper is <strong>open access (so anyone can download it) and <a href="http://onlinelibrary.wiley.com/doi/10.1002/geo2.10/abstract">it is available in the Geo website</a> . </strong></p>

The notes below are focusing on aspects that are relevant to <strong>Volunteered Geographic Information (VGI), Citizen Science and participatory sensing</strong> &#8211; aspects of Big Data/Open data are noted more briefly.</p>
  <p>Rob Kitchin opened with a talk to frame the workshop, highlighting the history of city data (see <em><a href="http://www.maynoothuniversity.ie/progcity/2015/08/new-paper-data-driven-networked-urbanism/">his paper on which the talk is based</a></em>). We are witnessing a transformation from data-informed cities to data-driven cities. Within these data streams we can include Big Data, official data, sensors, drones and other sources. The sources also include volunteered information such as social media, mapping, and citizen science. Cities are becoming instrumented and networked and the data is assembled through <strong>urban informatics </strong>(focusing on interaction and visualisation) and <strong>urban science </strong>(which focus on modelling and analysis(<strong> </strong>. There is a lot of critique &#8211; with relations to data, there are questions about the politics of urban data, corporatisation of governance, the use of buggy, brittle and hackable urban systems, and social and ethical aspects.  Examples to these issues include politics: accepting that data is not value free or objective and influenced by organisations with specific interest and goals. Another issue is the corporatisation of data, with questions about data ownership and data control. Further issues of data security and data integrity when systems are buggy and brittle &#8211; there have been cases of hacking into a city systems already. Social, Political, and ethical aspects include data protection and privacy, dataveillance/surveillance, social sorting through algorithms, control creep, dynamic pricing and anticipatory governance (expecting someone to be a criminal). There are also technical questions: coverage, integration between systems, data quality and governance (and the communication of information about quality), and skills and organisational capabilities to deal with the data.<br />
  The workshop is to think critically about the data, and asking questions on how this data is constructed and run.</p>
  <p>The talk by <strong>Jim Thatcher &amp; Craig Dalton</strong> &#8211; explored provenance models of data. A core question is how to demonstrate that data is what is saying it is and where it came from. In particular, they consider how provenance applies to urban data. There is an epistemological leap from an individual (person) to a data point(s) &#8211; per person there can be up to 1500 data attribute per person in corporate database. City governance require more provenance in information than commercial imperatives. They suggest that data user and producers need to be aware of the data and how it is used.</p>
  <p><strong>Evelyn Ruppert</strong> asked <strong>where are the data citizens?</strong> Discuss the politics in data, and thinking about the people as subjects in data &#8211; seeing people as actors who are intentional and political in their acts of creating data. Being digital mediates between people and technology and what they do. There are myriad forms of subjectivation &#8211; there are issues of rights and how people exercise these rights. Being a digital citizens &#8211; there is not just recipient of rights but also the ability to take and assert rights. She used the concept of cyberspace as it is useful for understanding rights of the people who use it, while being careful about what it means. There is conflation of cyberspace and the Internet and failures to see it as completely separate space. She sees Cyberspace is the set of relations and engagements that are happening over the Internet. She referred to her recent book &#8216;<a href="http://www.rowmaninternational.com/books/being-digital-citizens">Being Digital Citizens</a>&#8216;. Cyberspace has relationships to real space &#8211; in relations to Lefebvre concepts of space. She use speech-act theory that explore the ability to act through saying things, and there is a theoretical possibility of performativity in speech. We are not in command of what will happen with speech and what will be the act. We can assert acts through the things we do, and not only in the thing we say and that&#8217;s what is happening with how people use the Internet and construct cyberspace.</p>
  <p><strong>Jo Bates</strong> talked about data cultures and power in the city. Starting from hierarchy in dat and information. Data can be thought as &#8216;alleged evidence&#8217; (Buckland) &#8211; data can be thought as material, they are specific things &#8211; data have dimensionality, weight and texture and it is existing something. <a href="https://en.wikipedia.org/wiki/Neo-Gramscianism">Cox, in 1981, view the relationship between ideas, institutions and material capabilities</a> &#8211; and the tensions between them &#8211; institutions are being seen as stabilising force compare to ideas and material capabilities, although the institutions may be outdated. She noted that sites of data cultures are historically constituted but also dynamic and porous &#8211; but need to look at who participate and how data move.</p>
  <p>The session followed by a discussion, some of the issues: I&#8217;ve raised the point of the impact of methodological individualism on Evelyn and Jim analysis &#8211; for Evelyn, the digital citizenship is for collectives, and for Jim, the provenance and use of devices is done as part of collectives and data cultures. Jo explored the idea of &#8220;progressive data culture&#8221; and suggested that we don&#8217;t understand what are the conditions for it yet &#8211; the inclusive, participatory culture is not there. For Evelyn, data is only possible through the action of people who are involved in its making, and the private ownership of this data does not necessarily make sense in the long run. Regarding hybrid space view of cyberspace/urban spaces &#8211; they are overlapping and it is not helpful to try and separate them. Progressive data cultures require organisational change at government and other organisations. Tracey asked about work on indigenous data, and the way it is owned by the collective &#8211; and  noted that there are examples in the arctic with a whole setup for changing practices towards traditional and local knowledge. The provenance goes all the way to the community, the <a href="http://arctic-sdi.org/">Arctic Spatial Data Infrastructure </a>there are lots of issues with integrating indigenous knowledge into the general data culture of the system. The discussion ended with exploration of the special case of urban/rural &#8211; noting to the code/space nature of agricultural spaces, such as the <a href="http://www.wired.com/2015/04/dmca-ownership-john-deere/">remote control of John Deere tractors</a>, use of precision agriculture, control over space (so people can&#8217;t get into it), tagged livestock as well as variable access to the Internet, speed of broadband etc.</p>
  <p>The second session looked at <em><strong>Data Infrastructure and platforms</strong></em>, starting with <strong>Till Straube</strong> who looked at <strong>Situating Data Infrastructure</strong>. He highlighted that Git (GitHub) blurs the lines between code and data, which is also in functional programming &#8211; code is data and data is code. He also looked at software or conceptual technology stacks, and hardware is at the bottom. He therefore use the concept of topology from Science and Technology Studies and Actor-Network Theory to understand the interactions.</p>
  <p><strong>Tracey Lauriault</strong> &#8211; <strong>ontologizing the city</strong> &#8211; her research looked at the transition of Ordnance Survey Ireland (OSi) with their core GIS &#8211; the move towards object-oriented and rules based database. How is the city translated into data and how the code influence the city? She looked at OSi, and the way it produce the data for the island, and providing infrastructure for other bodies (infrastructure). OSi started as colonial projects, and moved from cartographical maps and digital data model to a full object-oriented structure. The change is about understanding and conceptualising the mapping process. The ontology is what are the things that are important for OSi to record and encode &#8211; and the way in which the new model allows to reconceptualise space &#8211; she had access to a lot of information about the engineering, tendering and implementation process, and also follow some specific places in Dublin. She explore her analysis methods and the problems of trying to understand how the process work even when you have access to information.</p>
  <p>The discussion that follows explored the concept of &#8216;stack&#8217; but also ideas of considering the stack at planetary scale. The stack is pervading other ways of thinking &#8211; stack is more than a metaphor: it&#8217;s a way of thinking about IT development, but it can be flatten. It gets people to think how things are inter-relations between different parts. Tracey: it is difficult to separate the different parts of the system because there is so much interconnection. Evelyn suggested that we can think about the way maps were assembled and for what purpose, and understanding how the new system is aiming to give certain outcomes. To which Tracey responded that the system moved from a map to a database,<a href="https://en.wikipedia.org/wiki/Ian_Hacking"> Ian Hacking approach </a>to classification system need to be tweaked to make it relevant and effective for understanding systems like the one that she&#8217;s exploring. The discussion expanded to questions about how large systems are developed and what methodologies can be used to create systems that can deal with urban data, including discussion of software engineering approaches, organisational and people change over time, &#8216;war stories&#8217; of building and implementing different systems, etc.</p>
  <p>The third and last session was about <em><strong>data analytics and the city</strong></em> &#8211; although the content wasn&#8217;t exactly that!</p>
  <p>Gavin McArdle covered <a href="http://papers.ssrn.com/sol3/papers.cfm?abstract_id=2643430">his and Rob Kitchin paper</a> on the veracity of open and real-time urban data. He highlighted the value of open data &#8211; from claims of transparency and enlighten citizens to very large estimation of the business value. Yet, while data portals are opening in many cities, there are issues with the veracity of the data &#8211; metadata is not provided along the data. He covered spatial data quality indicators from ISO, ICA and transport systems, but questioned if the typical standard for data are relevant in the context of urban data, and maybe need to reconsider how to record it. By looking at 2 case studies, he demonstrated that data is problematic (e.g. indicating travel in the city of 6km in 30 sec). Communicating the changes in the data to other users is an issue, as well as getting information from the data providers &#8211; maybe possible to have meta-data catalogue that add information about a dataset and explanation on how to report veracity. There are facilities in Paris and Washington DC, but they are not used extensively</p>
  <p>Next, <strong>Chris Speed</strong> talked about <strong>blockchain city &#8211; spatial, social and cognitive ledgers</strong>, exploring the potential of distributed recording of information as a way to create all forms of markets in information that can be controlled by different actors.</p>
  <p>I have closed the session with a talk that is based <a href="https://povesham.wordpress.com/2015/08/13/beyond-quantification-a-role-for-citizen-science-and-community-science-in-a-smart-city/">on my paper for the workshop</a>, and the slides are available below.</p>
  <p>The discussion that followed explored aspects of representation and noise (produced by people who are monitored, instruments or &#8216;dirty&#8217; open data), and some clarification of the link between the citizen science part and the philosophy of technology part of my talk &#8211; highlighting that Borgmann use of &#8216;natural&#8217;,&#8217;cultural&#8217; and &#8216;technological&#8217; information should not be confused with the everyday use of these words.</p>

We were interest to &#8216;explore and debate current research and practice moving beyond motivation, to consider the associated enthusiasm, materials and meanings of participating in citizen science and VGI.’</p>
  <p>As Hilary couldn&#8217;t attend the conference, we started the session with a discussion about experiences of enthusiasm &#8211; for example, <a title="Volunteer computing, engagement and enthusiasm" href="https://povesham.wordpress.com/2015/03/11/volunteer-computing-engagement-and-enthusiasm/">my own experience with IBM World Community Grid</a>.  Jeroen Verplanke raised the addiction in volunteer thinking projects, such as logging in to Zooniverse or Tomnod project, and time fly-by. Mairead de Roiste described mapping wood-pigeon in New Zealand &#8211; public got involved because they wanted to help, but when they hear that the data wasn&#8217;t use, they might lose interest. Urgency can also be a form influencing participation.</p>
  <p>Britta Ricker &#8211; University of Washington Tacoma &#8211;<strong> <em>Look what I can do! Harnessing drone enthusiasm for increased motivation to participate</em>.</strong> On-going research. Looking at the Geoweb &#8211; it allow people to access information, and made imagery available to the public, and the data is at the whim of whoever give us the data. With drones, we can send them up when we want or need to. Citizen Science is deeply related to geoweb &#8211; challenge is to get people involve and make them stay involved. We can harness drone enthusiasm &#8211; they evoke negative connotation but also thinking about them for good &#8211; humanitarian applications. Evidence for the enthusiasm is provided by YouTube where there are plenty of drone video &#8211; 3.44M &#8211; lots of action photography: surfing community and GoPro development. People are attached to the drone &#8211; jumping to the water to save them. So how the enthusiasm to drones can be harnessed to help participatory mapping. We need to design a workflow around stages: pre-flight, flight, post processing. She partnered with water scientists to explore local issues. There are considerations of costs and popularity &#8211; and selected quadcopter for that. DJI Phantom Vision 2+. With drones need to read the manual and plan the flight. There are legal issues of where it is OK to fly, and Esri &amp; MapBox provide information on where you can fly them. Need to think of camera angle &#8211; need also to correct fisheye, and then process the images. Stitch imagery can be done manually (MapKnitter/QGIS/ArcGIS). Possible to do it in automated software, but open source (e.g. OpenDroneMap) is not yet good enough in terms of ease of use. Software such as Pix4D is useful but expensive. Working with raster data is difficult, drones require practice, and software/hardware is epensive &#8211; not yet ready to everyone. NGOs can start using it. Idea: sharing photos , classifying images together by volunteers.</p>
  <p>Brittany Davis &#8211; Allegheny College &#8211; <em><strong>Motivated to Kill: Lionfish Derbies, Scuba Divers, and Citizen Science</strong></em>. Lionfish are stunning under water &#8211; challenging to differentiate between the two sub species but it doesn&#8217;t matter if you&#8217;re trying to catch them. They are invasive species and are without predators, exploded &#8211; especially from 2010. There is a lot of informational campaign and encouraging people to hunt them, especially in dive centres &#8211; telling people that it is a way to save a Caribbean reefs. When people transform themselves from &#8216;benign environmental activity&#8217; to &#8216;you tell me that I can hunt? cool!&#8217;. Lionfish is tasty so having the meat for dinner is a motivation. Then doing &#8216;lionfish derbies&#8217; &#8211; how many can you kill in a day. Seen a lot of enthusiasm for lionfish derbies. Trying to sign up people to where they go but they are not recording where they hunt the lionfish. People go to another site for competition as they want to capture more. REEF trying to encourage a protocol for capturing them, and there are cash prizes for the hunting. They use the catch to encourage people to hunt lionfish. Derbies increase in size &#8211; 14832 were removed from 2009 to 2014 and some evidence for the success of the methodology. There was a pressure on &#8216;safely and humanely capture and euthanase these fish&#8217; &#8211; challenge for <a href="http://www.padi.com/scuba-diving/about-padi/why-choose-padi/">PADI</a> who run special scuba courses that are linked to conservation. People hear about the hunting and that motivate people to go diving. There is a very specific process of REEF sanctioned lionfish derby, so trying to include recording and public information. But there are challenges below the depth of recreational divers. She also explored if it is possible to improve data collection for scientists.</p>
  <p>Cheryl Gilge &#8211; University of Washington &#8211; <strong>The rhetorical flourish of citizen participation (or, the formation of cultural fascism?)</strong> offered a theoretical analysis of citizen science and web 2.0 as part of a wider project to understand labour relationships and power. She argues that there is agency to the average citizen to link to their environment. They have the ability to contribute, and to receive information is part of Web 2.0. As a technology layer, it changes both the individual and society levels. The collaboration and participation in Web 2.0 is framed around entrepreneurialism, efficiencies, and innovation. The web is offering many opportunities to help wider projects, where amateur and expert knowledge are both valued. However, there is a risk of reducing the politics of participation &#8211; semblance of agency. Democratic potential &#8211; but also co-opting the spirit is in evidence. There is plenty of examples of inducing individuals to contribute data and information, researchers are eager to understand motivation over a long period. Rational system to explain what is going on can&#8217;t explain the competing goals and values that are in action. The desire to participation is spread &#8211; fun, boredom etc. From understanding people as &#8216;snowflakes&#8217; to unashamed exploitation. Why do people contribute to the wider agenda? As provocation, harnessing crowd potential to neoliberalisation agenda of universities. We give freedom to the efficiency and promise of digital tools. Government promise &#8216;open government&#8217; or &#8216;smart cities&#8217; that put efficiency as the top value. Deep libertarian desire for small government is expressed through technology. The government have sensors that reduce cost of monitoring what is happening. In the academic environment &#8211; reduce funding, hiring freeze, increase in pressure to publish &#8211; an assumption that it is possible to mechanically produce top research. Trading in ideas are less valued. Desire for capacity of information processing, or dealing with humanitarian efforts &#8211; projects like Galaxy Zoo require more people to analyse the masses of data that research produces, or mapathons to deal with emergencies. Participants are induced to do more through commitment to the project and harnessing enthusiasm. Adding inducement to the participants. She introduce the concept of micro-fascism from Guattari  &#8211; taking over freedoms in the hope of future promises. It enable large group formation to happen &#8211; e.g. identities such as I&#8217;m Mac/PC &#8211; it is harder to disconnect. Fascism can be defined as an ideology that rely on the masses in believing in the larger goals, the unquestioned authority of data in Web 2.0. Belief in technology induce researchers to get data and participation regardless of the costs. Open source is presented as democracy, but there are also similarities with fascism. Participation in the movement and participants must continue to perform. It bring uncomfortable participation &#8211; putting hope on these activities, but also happens in top down and bottom up, and Web 2.0. What is the ethical role of researchers who are involved in these projects? How do we value this labour? Need to admit that it is a political.</p>
  <p>In a final comment, Teresa Scassa pointed that we need to consider the implication of legitimising drones, killing fish or employing unpaid labour &#8211; underlying all is a moral discomfort.</p>
  <p>Afternoon, the two sessions on OpenStreetMap that Alan McConchie and I organised, taking the 10th birthday of OSM as a starting point, this session will survey the state of geographical research on OpenStreetMap and recognising that OSM studies are different from VGI. The session is supported by the <a href="http://vgibox.eu/"><strong>European COST Energic (COST Action IC1203) network</strong></a>: European Network Exploring Research into Geospatial Information Crowdsourcing.</p>

  <p>Jennings Anderson, Robert Soden, Mikel Maron, Marina Kogan &amp; Ken Anderson &#8211; University of Colorado, Boulder &#8211; <em><a href="http://meridian.aag.org/callforpapers/program/AbstractDetail.cfm?AbstractID=67690">The Social Life of OpenStreetMap: What Can We Know from the Data? New Tools and Approaches</a>. </em>OSM provides a platform to understand human centred computing. The is very valuable information in OSM history file, and they built a framework (<a href="https://github.com/Project-EPIC/epic-osm">EPIC OSM</a>) that can run spatial and temporal queries and produces JSON output that can be then analysed. They are use existing tools and software frameworks to deliver it. The framework was demonstrated: can ask questions by day, or by month and even bin them by week and other ways. Running such questions which are evaluated by Ruby, so easy to add more questions and change them. They already use the framework in a paper in CHI about the Haiti earthquake (see video below).  Once they&#8217;ve created the underlying framework, they also developed an interface &#8211; OSM Markdown &#8211; can embed code and see changesets, accumulative nodes collected and classification by type of user. They are also providing information with tags. When analysing Haiti response, they see spike in noted added and what they see in buildings &#8211; the tags of collapse=yes</p>

  <p>Christian Bittner &#8211; <em><a href="http://meridian.aag.org/callforpapers/program/AbstractDetail.cfm?AbstractID=64457">Diverse crowds, diverse VGI? Comparing OSM and Wikimapia in Jerusalem</a>. </em>Christian looked at differences in Wikimapia and OSM as sources of VGI. Especially interested in the social implications such as the way exclusion plays in VGI &#8211; challenges between Palestine/Israel &#8211; too contradicting stories that play out in a contested space, and there are conflict and fights over narratives that the two sides enact in different areas. With new tools, there is a &#8216;promise&#8217; of democratisation &#8211; so a narrative of collaboration and participation. In crowdsourced geographic information we can ask: who is the crowd, and who is not? Studying social bias in OSM is a topic that is being discussed in the literature. The process is to look at the database of OSM. Analysing the data and metadata and used the municipal boundaries of Jerusalem. Simplified representation of the city, and region are classified by majority &#8211; Arab or Jewish. Then used cartograpms according to size of population and the amount of information collected.In OSM, Jewish areas are over-represented, while Arab areas are under-represented. Bias toward male from privileged socio-economic background as participants. In Wikimapia, the process is tagging places and uses visual information from Google. Wikimapia is about qualitative information so objects are messy and overlap, with no definitions of what consist of a place. In Wikimapia, there is much more descriptions of the Arab areas which are over-represented. The amount of information in Wikimpaia is smaller &#8211; 2679 objects, compared to 33,411 ways in OSM. In OSM there is little Arabic, and more Hebrew, though Latin is the most used language. Wikimapia is the other way around, with Hebrew in the minority. The crowd is different between projects. There are wider implications &#8211; diverse crowd so diverse VGI? VGI is diverse form of data, and they are produced in different ways from different knowledge cultures. He call for very specific studies on each community before claiming that VGI is general form of information.</p>
  <p>Tim Elrick  &amp; Georg Glasze &#8211; University of Erlangen-Nuremberg, Germany &#8211;  <em><a href="http://meridian.aag.org/callforpapers/program/AbstractDetail.cfm?AbstractID=64552">A changing mapping practices? Representation of Places of Worship in OpenStreetMap and other sources</a>. </em>The start of the process is noticing that churches are presented on official maps, but not a masques, noticing how maps are used to produce specific narratives. What happen in new forms of mapping? In Google Maps, the masque is presented, but not the church, in OSM both are mapped. What is happening? In the old topographic maps, the official NMAs argue that it provides a precise representation &#8211; but failing to do so in terms of religious differences. Some state do not include non-Christian places of worship &#8211; the federal mapping agency came with symbols for such places (masques, synagogues) but the preference from the states NMAs was for a generic mark for all non-Christian places that do not differentiate between religions. USGS just have single mark for house of worship &#8211; with cross. The USGS suggested to carry out crowdsourcing to identify places of worship so they are willing to change. In OSM there are free tagging and marks for religion, but the rendering dictate only some tags. In 2007 there was suggestion to change rendering of non-Christian places. Once Steve Chilton created cartographic symbols for the change. OSM do-ocracy can lead to change, but in other places that use OSM this was not accepted &#8211; there are different symbols in OpenCycleMaps. In Germany, there are conflicts about non visible places of worship (e.g. Masque in social club). Adaptive approach to dealing with location in OSM. In Google there is a whole set of data sources that are used, but also crowdsourcing which go to moderators in Google &#8211; no accountability or local knolwedge. Places of worship is not transparent. Categorisation and presentation change with new actors &#8211; corporate and open data. Google use economy of attention.</p>
  <p>Alan McConchie &#8211; University of British Columbia &#8211; <em><a href="http://meridian.aag.org/callforpapers/program/AbstractDetail.cfm?AbstractID=64343">Map Gardening in Practice: Tracing Patterns of Growth and Maintenance in OpenStreetMap</a></em>. Looking at history of OSM. Editing existing features is an important as adding new ones &#8211; having to collaborate and dealing with other people data. In the US, OSM is a mixed of volunteer and imported data &#8211; it&#8217;s ongoing aspect of the project. Questions: do the &#8216;explorers&#8217; stick around? the people who like empty spaces . Do imports hinder the growth of the community? and does activity shift to &#8216;gardening&#8217;? The TIGER import in 2007 have been significant to the growth of the project. There are also many other imports &#8211; address in Denmark, French land cover, incomplete land cover imports in Canada. There was community backlash from people who were concerned about the impact of imports (e.g. Crowe 2011; Fredrik Ramm, 2012, Tobias Knerr, 2015). The debate is also between different regional factions. There is an assumption that only empty areas are exciting. That is problematic in terms of someone joining now in Germany. New best practices that are evolving Imports in Seattle were used to encourage the community and build it. Zielstra et al. 2013 explored imports show different growths, but not so simple as just to pin it on imports. Alan takes the &#8216;Wiki Gardening&#8217; concept &#8211; people who like to keep things tidy and well maintained. Analysing small areas. Identifying blank spots, but trying to normalise across city in the world &#8211; e.g. population from the gridded population of the world. Exploring edits per month. We see many imports happening all the time. At individual city, explore the behaviour of explorers and those that never mapped the unknown. In London, new mappers are coming in while at Vancouver the original mapper are the one that continue to maintain the map. There is power law effects that trump anything else, and shift to new contributors and it is not clear cut.</p>
  <p><a href="http://meridian.aag.org/callforpapers/program/ParticipantDetail.cfm?IMISID=90013180">Monica G. Stephens</a> &#8211; University at Buffalo &#8211; Discussant: she started looking at OSM only few years ago, because of a statement from Mike Goodchild that women are not included, so done survey of internet users in Google Maps and OSM. She found that geotagging is much more male &#8211; more then just sharing image. In her survey she noticed gender bias in OSM. Maps are biased by the norms, traditions, assumptions and politics of map maker (Harley 1989). Biases &#8211; but biases of map maker &#8211; bikes in Denver (what interest them), or uneven representation of Hebrew in Jerusalem, or Religious attributes. Also there is how the community makes decision &#8211; how to display information? what to import? There are issues of ethos &#8211; there are fundamental differences in UK and Germany communities to US mapping communities. This lead to interesting conversations between these communities. There are also comparison, Wikimapia, Google Maps, Topo Maps &#8211; the tell us what OSM is doing. OSM democracy is more efficient and responding to communities ideas. The discussions on tagging childcare &#8211; rejected but there are discussions that led to remapping of tags in response to the critique. Compare to Google Maps, who was creating local knowledge? in Google Maps 96% of reviewers are male (in Google Map Maker 2012), so the question is who is the authority that govern Wikimapia.</p>
  <p><a href="http://meridian.aag.org/callforpapers/program/SessionDetail.cfm?SessionID=22000&amp;cal=true">OpenStreetMap Studies 2</a>  included the following:</p>
  <p>Martin Loidl &#8211; Department of Geoinformatics, University of Salzburg &#8211; <em><a href="http://meridian.aag.org/callforpapers/program/AbstractDetail.cfm?AbstractID=65631">An intrinsic approach for the detection and correction of attributive inconsistencies and semantic heterogeneity in OSM data</a></em>. Martin come from data modelling perspective, accepting that OSM is based on bottom-up approach, with flat data modelling and attributes, with no restriction on tag usage. There are attributive inconsistencies. Semantics heterogeneity is influencing visualisation, statistics and spatial analysis. Suggesting to improve results by harmonization and correction through estimation. There has been many comparison of OSM quality over the years. There is little work on attribute information. Martin suggested an intrinsic approach that rely on the data in OSM &#8211; expecting major roads to be connected and consistent. Showing how you can attributes in completeness. Most of the road in OSM are local roads and  and there is high heterogeneity, but we need them and we should care about them. There are issues with keeping the freedom to tag &#8211; it expose the complexity of OSM.</p>

  <p>Peter A. Johnson &#8211; University of Waterloo <em><a href="http://meridian.aag.org/callforpapers/program/AbstractDetail.cfm?AbstractID=65737">Challenges and Constraints to Municipal Government Adoption of OpenStreetMap</a></em>. The collaboration of MapBox with NYC &#8211; agreement on data sharing was his starting point and motivation to explore how we can connect government and citizens to share data. Potentially, OSM community will help with official data, improve it and send it back. Just delivering municipal data over OSM base map is not much &#8211; maybe we need to look at mirroring &#8211; questions about currency, improvement of our services, and cheaper/easier to get are core questions. Evaluating official data and OSM data. Interview with governments in Canada, with range of sizes &#8211; easy in large cities, basic steps in medium and little progress in rural places. No official use of OSM, but do make data available to OSM community, and anecdotal evidence of using it for different jobs unofficially. Not seeing benefits in mirroring data, and they are the authoritative source for information, no other data is relevant. Constraints: not sure that OSM is more accurate and risk averse culture. They question fit with organisation needs, lacking required attributes, and they do see costs in altering existing data. OSM might be relevant to rural and small cities where data is not being updated.</p>
  <p>Muki Haklay &#8211; University College London <em><a href="http://meridian.aag.org/callforpapers/program/AbstractDetail.cfm?AbstractID=64448">COST Energic &#8211; A European Network for research of VGI: the role of OSM/VGI/Citizen Science definitions</a>. </em>I&#8217;ve used some of the concepts that I <a title="Observing from afar or joining the action: OSM and GIScience research" href="https://povesham.wordpress.com/2011/07/16/observing-from-afar-or-joining-the-action-osm-and-giscience-research/">first presented in SOTM 2011 in Vienna</a>, and extended them to the general area of citizen science and VGI. Arguing that academics need to be &#8216;critical friends&#8217;, in a nice way, to OSM and other communities. The different talks and Monica points about changes in tagging demonstrate that this approach is effective and helpful.</p>

  <p><strong>Discussant:</strong> <a href="http://meridian.aag.org/callforpapers/program/ParticipantDetail.cfm?IMISID=90037143">Alan McConchie</a> &#8211; University of British Columbia. The later session looked at intrinsic or extrinsic analysis of OSM &#8211; such as Martin&#8217;s work on internal consistency, there are issues of knowing specific person in the bits of the process who can lead to the change. There is a very tiny group of people that make the decisions, but there is a slow opening towards accountability (e.g. OSM rendering style on Github). There are translation of knowledge and representation that happen in different groups and identifying how to make the information correctly. There is a sense of &#8216;no one got the right answer&#8217;. Industry and NGOs also need to act as critical friends &#8211; it will make it a better project. There is also critical GIS conversations &#8211; is there &#8216;fork&#8217; within the OSM studies? We can have conversations about these issues.</p>
  <p>Follow up questions explored the privacy of the participants and maybe mentioned it to participants and the community, and also the position as participant or someone who alters the data and as a researcher &#8211; the implications of participatory observations.</p>

summary:
  The Association of American Geographers conference is just around the corner &#8211; between 21 and 24 April, held in Chicago. I&#8217;ve already marked some sessions that I think worth noting (and was involved in the organisation of several sessions, too). Here is a list of interesting sessions, following suggestion to do so by David O&#8217;Sullivan and &#8230; <a href="https://povesham.wordpress.com/2015/04/09/aag-sessions-critical-giscience-geoweb-and-citizen-science/" class="more-link">Continue reading <span class="screen-reader-text">AAG sessions &#8211; Critical GIScience, GeoWeb and Citizen&#160;Science</span></a>

Around the breakfast tables, new connections were emerging. Similarly to the registration queue in the first day, people where open and friendly, starting conversations with new acquaintances, and sharing their interest in citizen science. An indication to the enthusiasm was that people continued talking as they departed to the morning sessions. <a href="https://povesham.files.wordpress.com/2015/02/dscn0087.jpg"><img data-attachment-id="1480" data-permalink="https://povesham.wordpress.com/2015/02/13/citizen-science-2015-second-day/dscn0087/" data-orig-file="https://povesham.files.wordpress.com/2015/02/dscn0087.jpg" data-orig-size="4608,3456" data-comments-opened="1" data-image-meta="{&quot;aperture&quot;:&quot;3.7&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;COOLPIX S9700&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;1423756849&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;4.5&quot;,&quot;iso&quot;:&quot;250&quot;,&quot;shutter_speed&quot;:&quot;0.033333333333333&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;1&quot;}" data-image-title="CSA breakfast" data-image-description="" data-medium-file="https://povesham.files.wordpress.com/2015/02/dscn0087.jpg?w=300" data-large-file="https://povesham.files.wordpress.com/2015/02/dscn0087.jpg?w=660" class="alignright size-medium wp-image-1480" src="https://povesham.files.wordpress.com/2015/02/dscn0087.jpg?w=300&#038;h=225" alt="CSA breakfast " width="300" height="225" srcset="https://povesham.files.wordpress.com/2015/02/dscn0087.jpg?w=300&amp;h=225 300w, https://povesham.files.wordpress.com/2015/02/dscn0087.jpg?w=600&amp;h=450 600w, https://povesham.files.wordpress.com/2015/02/dscn0087.jpg?w=150&amp;h=113 150w" sizes="(max-width: 300px) 100vw, 300px" /></a></p>
  <p><strong>5A Symposium: <a href="http://programme.exordo.com/cs2015/delegates/presentation/12/">Linking Citizen Science and Indigenous Knowledge: an avenue to sustainable development</a> </strong></p>
  <p>The session explored the use of different data collection tools to capture and share traditional knowledge. Dawn Wright, Esri chief scientist started with <strong>Emerging Citizen Science Initiatives at Esri. </strong>Dawn started with Esri view of science &#8211; beyond fundamental science understanding, it is important to see science as protecting life, enabling stewardship and to share information about how the Earth works, how it should look (<a href="http://en.wikipedia.org/wiki/Geodesign">geodesign</a>) and how we should look at the Earth. As we capture the data with various mobile devices &#8211; from mobile phones to watches and sensors we are becoming more geoaware and geoenabled. The area of geotechnologies that enable it &#8211; are apps and abilities such as storytelling are very valuable. Esri views geoliteracy as combination of understanding geography and scientific data &#8211; issues are more compelling when they are mapped and visualised. The <em>Collector for ArcGIS</em> provide the ability to collect data in the field, and it has been used by scouts as well as in <a href="http://www.esri.com/esri-news/arcuser/fall-2014/gis-helps-farmers-see-the-big-picture">Malawi where it is used by indigenous farmers</a> to help in managing local agriculture. There are also abilities to collect information in the browser with &#8216;GeoForm&#8217; that support such data collection. Maps were used to collect information about street light coverage and buffering the range that is covered. A third method is a <a href="http://storymaps.arcgis.com/en/">StoryMaps.arcgis.com</a> that allow to tell information with a narrative. <a href="https://play.google.com/store/apps/details?id=com.esri.labs.snap2map&amp;hl=en">Snap2Map</a> is an app that allow to link data collection and put it directly to story-maps. There is also a crowdsource.storymaps.arcgis.com that allow collection of information directly from the browser.</p>
  <p><img class="alignleft" style="margin:2px;" src="https://pbs.twimg.com/media/B9qKJeGCQAAWSBx.jpg" alt="" width="291" height="218" />Michalis Vitos, UCL &#8211; <strong>Sapelli, a data collection platform for non-literate, citizen-scientists in the rainforest. </strong>Michalis described the <a href="http://www.ucl.ac.uk/excites">Extreme Citizen Science group</a> &#8211; which was set up with the aim to provide tools for communities all over the world. In the Congo-basin communities face challenges from illegal logging and poaching , but forest people have direct competition for resources such as the trees that they use, and with the FLEGT obligations in the Republic of Congo, some protection is emerging. The team collaborate with a local NGOs which works with local communities, and there are challenges including literacy, energy, and communication. <a href="http://sapel.li">Sapelli</a> collector is an application work with different levels that allow the data collection area. The Sapelli launcher locks the interface of the phone, and allow specific functions to be exposed to the user. The issue of connectivity was address in communication procedures that use SMS. The issue of providing electricity can be done in different ways &#8211; including while cooking. There is a procedure for engaging with a community &#8211; starting with <a href="http://en.wikipedia.org/wiki/Free,_prior_and_informed_consent">Free and Prior Informed Consent</a>, and the process start with icons, using them in printed form and make sure that the icons are understood &#8211; after the agreement on the icons, there is an introduction to the smartphones &#8211; how to touch, how to tap and the rest of the basics. The next stage is to try it in the field. Sapelli is now available in Google Play &#8211; the next stage is to ensure that we can show the participants what they collected, but as satellite images are difficult to obtain, the group is experimenting with drone imagery and mapping to provide the information back to the community. In terms of the results to the community, the project is moving from development to deployment with a logging company. The development of the icons is based on working with anthropologists who discuss the issues with the community and lead the development of the icons. Not all the icons work and sometime need to be change. The process involved compensating the community for the time and effort that they put in.</p>
  <p>Sam Sudar, University of Washington &#8211; <strong>Collecting data with Open-Data-Kit (ODK) </strong>&#8211; Sam gave a background on the tool &#8211; the current version and the coming ODK 2.0. ODK is information management tools for collecting and storing data and making it usable, targeted at resource-constrained environment &#8211; anywhere where there is limited connectivity, without assuming smartphone literacy. It is used all over the world. It is being used in Kenya, and by Jane Goodall Institute (JGI) in Tanzania, the Surui tribe use it in Brazil to gain carbon credits, and the Carter Center in Egypt for election monitoring, as well as WWF in Rwanda. The technology is used in very diverse ways. Need to consider how technology empowers data collection. The ODK workflow is first, build the form, collect the data, and finally aggregate the results. ODK build / ODK XLSform is the way to build it in Excel, then there is ODK collect to render the forms, and finally ODK aggregate can run locally or on Google App Engine. There is a strong community around ODK with much support for it. In ODK 1.0 there is no data update on the mobile device, as it replicated the paper process. There is limitation for customisation of the interface, or linking to sensors. ODK 2.0 can provide better abilities and it allow syncing of information even it is done on the cloud. The ODK survey replacing ODK collect, and the ODK tables is a way to interact with data on the device. The intention is to make it possible to interact with the data in an easier way.</p>
  <p>A question from the audience asked if local communities worries about the data collected about them? ODK work with a lot of medical information, but the team doesn&#8217;t goes on the ground so it is left to whoever use the system to ensure ethical guidelines are followed. Michalis noted that there are not only problems with external body, but also cultural sensitivities about what data should be seen by whom, and there is an effort to develop tools that are responsive to it.</p>
  <p>Tanya Birch, Google Earth &#8211; <strong>Outreach Community-based field data collection and Google mapping tools </strong>the video include Jane Goodall work in Tanzania with Chimpanzee, due to habitat lost, there are less than 300,000 chimpanzee left in the wild. In the video, Lillian Pintea (JGI) noted the importance of satellite images that demonstrate all the bare hills in the area of Tanzania. That lead to improve the life of the local villagers so they become partners in conservation. The local communities are essential &#8211; they share the status of the work with the people in the village. The forest monitor role is to work across the area, collect data and monitor it to ensure that they can collected data with ODK. Location information is easier in tablet and then upload it to Google, and then it is shared with global effort to monitor forests. <a href="http://en.wikipedia.org/wiki/Gombe_Stream_National_Park">Gombe national park</a> is the laboratory for scaling up across the area of habitat of Chimpanzees and using Google abilities and reach to share it widely.</p>
  <p>Another question that came up was: How you have used the tools with youth or challenges of working with young people? Dawn noted that the engagement with youth, the term digital native is true and they end teaching the teachers on how to improve the apps. The presentations discussed the simplicity in technology so you don&#8217;t need to know what is going on in the background. Another question is: do people want to change the scale of analysis &#8211; standing in the point and taking a picture of a mountain, and how to address different scales? Dawn noted that the map as part of the collection tool allow people to see it as they collect the data and for example allow them to indicate the scale of what they viewed. Michalis noted that there is also the option in Sapelli to measure scale in football pitches, and Luis noted that in CyberTracker, there is an option to indicate that the information was collected in a different place to where the observer is. Data sharing is something that is important, but make sure that it can be exported in something as simple as</p>
  <p><strong>6E Symposium: <a href="http://programme.exordo.com/cs2015/delegates/presentation/131/">Human-Centred Technologies for Citizen Science</a> </strong></p>
  <p>Kevin Crowston (Syracuse U.) &amp; Andrea Wiggins (U. Maryland  &amp; symposium convener): <strong>Project diversity and design implications </strong>describe a survey in which most attention was paid to small projects, and by surveying a wider range of projects they discover different practices. To evaluate the design implication they suggested that we need to understand what the goal of the project, the participation activities &#8211; from science, conservation, to photography &#8211; different things that people are doing, with observations is the most common type of contribution (see <a href="http://firstmonday.org/ojs/index.php/fm/article/view/5520">First Monday paper</a>). Data quality come up in all the projects and there are different strategies to deal with it. There are diversities of engagement &#8211; from conference and meetings to social media. There are also rewards for participation &#8211; some projects are not doing rewards at all, others provide volunteer appreciation, training , equipment and another approach is to provide competitive rewards in leaderboards. There are also socialisation &#8211; and even formal education. Funding &#8211; diverse, from grants, private contributions, to sponsorship and sustainability is an issue.</p>
  <p><em>Mobile and Social Technologies</em><br />
  -Anne Bowser (U. Maryland) <strong> Gamifying phenology with Floracaching app</strong> &#8211; geocaching for plants &#8211; the application focuses on phenology and earlier version was developed for <a href="http://budburst.org/">Project BudBurst</a>. Traditional volunteers focus contribution to science, while millennials might be interested in mobile app that is based on games. Embedded maps can be used to create a cache and there is a leader-board and points. <a href="http://annebowser.com/floracaching.html">Floracaching</a> was created from paper prototyping and focus groups. They found perception of gamification was important to millennials, they also enjoyed competition. Also wanted to be told what to do and feedback on how they&#8217;ve done. &#8216;I&#8217;m not going to drive an hour to see a plant bloom&#8217; . Missions can be added to the design and help people to learn the application and the data collection.</p>
  <p>-Michalis Vitos (UCL): <a href="http://sapel.li">Sapelli</a>, a mobile data collection platform for non-literate indigenous communities, Michalis covered Sapelli, and the importance of the interface design (see previous session). The design of the icons is being discussed with, effectively, paper prototyping</p>
  <p>-Muki Haklay (UCL): Geographical human-computer interaction for citizen science apps (I&#8217;ll blog it later!)</p>
  <p>-Matt Germonprez, Alan Kolok, U. Nebraska Omaha, &amp; Matt Levy (San Francisco State U.): <strong>Enacting citizen science through social media </strong>&#8211;<strong> </strong>Matt come from a technology angle &#8211; he suggested that social media is providing different form of information, and social media &#8211; can it be integrated into a citizen science projects. The science project is to monitor <a href="http://en.wikipedia.org/wiki/Atrazine">Atrazine</a> which started in 2012, with a process similar to a litmus test, the project worked, but they wanted to use social media in the social setting that they work. Facebook wasn&#8217;t used beyond the information, but Twitter and Instagram was used to report observations publicly. The problems &#8211; no social conversations, so the next stage they want to maintain social conversation as the next goal. The  project can be found when you search for <a href="http://www.unomaha.edu/news/2014/06/homepage/atrazine.php">Lil&#8217; Miss Atrazine</a>.</p>
  <p><em>Developing Infrastructures</em><br />
  -Jen Hammock (Smithsonian Institution): An infrastructure for data distribution and use, the aim of the project of looking at snails &#8211; findability problem, a tool that they want to develop is for data search &#8211; so following different sources for information, and merging the taxa, location, as well as providing alerts about interests. Notification will be provided to the researcher and to the contributor. There can be knowledge about the person that contribute the information. There are technical and social barriers &#8211; will researchers and experienced naturalists be interested in sharing information.</p>
  <p>-Yurong He (U. Maryland): Improving biodiversity data sharing among diverse communities. looking at biodiversity &#8211; and the <a href="http://eol.org/">encyclopaedia of life</a>. There are content partners who provide the data. She looked at 259 content partners and found 6 types of data providers &#8211; and they are professional organisations that operate over time such as IUCN, NHM etc. The second type is repositories, professional database emerge in the 1990s. There are citizen science intiative and communities of interest, such as <a href="http://www.xeno-canto.org/">Xeno-Canto</a> for bird song. Fourth, social media platforms such as wikipedia,  Fifth, education communities who add information while they focus on education and finally subsidiaries. We need to know the practices of the providers more to support sharing of information.</p>
  <p>-S. Andrew Sheppard (U. Minnesota &amp; Houston Engineering, Inc.): Facilitating scalability and standardization. Andrew talked about the <a href="https://wq.io/">wq framework</a>. He focused on collection, storage and exchange. Standards are making possible to make projects work together, there are devices, field notes, computers, phones &#8211; but it is challenging to coordinate and make them all work together. Web browsers are based on standards are making it possible to work across platforms. Javascript is also supported across platforms. The wq.app provide the ability to collect information. The exchange require sharing data from different sources, Need to build the software to adapt to standards &#8211; wq.io is a platform to allow the creation of multiple links. Use standards, HTML5 and build adaptable tools for data exchange</p>
  <p>-Stuart Lynn, Adler Planetarium &amp; Zooniverse: Developing tools for the next scientific data deluge. Stuart discussed about their online community. They have 1.2m users. The challenge in the future is that there are going to be many projects and data sources that give huge amount of data. The aim is to partner with machine learning algorithm developers but how to keep the crowd interested and not just give the most difficult cases with no opportunity to learn or progress slowly. Gamification can be stressful, so they try to give more information and learning. They also try to create a community and discuss the issues. There is huge distribution of comments &#8211; and deepening engagement. There is no one size fits all and we need to model and understand them better.</p>
  <p><em>Contributors and Communities</em><br />
  -Jenny Preece (U. Maryland): Motivating and demotivating factors for long-term participation &#8211; what motivate people to come back again and again. The different motivational aspects &#8211; describing the work of the late Dana Rotman who collected information in the US, India and Costa Rica. 142 surveys from the us, 156 from India and also interviews in the three countries. She used grounded theory approach and developed a framework initial, and for long term impact there are internal and external motivation. Demotivations &#8211; time, problems with technology, long commitment with the task.</p>
  <p>-Carsten Oesterlund, Gabriel Mugar, &amp; Kevin Crowston (Syracuse U.): Technology features and participant motivations, the heterogeneity and variety of participants &#8211; how might we approach them? people change over time? looking at zooniverse &#8211; specifically planet hunters, there are annotations, talk and other sources of information. The talk pages &#8211; new comers and encouraged to annotate and comment about the image and also looking at what other people have done. They also find people that are more experienced. Use of talk change over time, people start putting in comments, then they go down and stop commenting and then later on started putting more information. There is also role discovery in terms of engagement and what they do in their community.</p>
  <p>-Charlene Jennet (UCL): Identifying and promoting creativity &#8211; creativity is a puzzling question, which is debated in psychology with some people look for breakthrough moment, while other look at everyday creativity. There are examples of projects that led to creativity &#8211; such as foldit, in terms of everyday creativity in citizen cyberscience and conducting interviews with volunteers and results include artwork from the old weather forum or the Galaxy Zoo Peas and eyewire chatbots that were created for members. People who are engaged in the project are contributing more to the project. Providing feedback on progress is important, and alos regular communication and personal feedback in blogs and answering in tweeters. Event help and also need to have ability role management.</p>
  <p>-Carl Lagoze (U. Michigan) Inferring participant expertise and data quality &#8211; focusing on eBird and there is a paper in big data and society. The standard way is to control the provenance of the data. The library is creating &#8216;porous zone&#8217; so today there is less control over the who area. There are barriers that break down between novices and experts. How can we tell experts/non experts &#8211; this happen across areas, and it is sort of distributed sensor network with weak sensors. are there signal in the data that help you to identify people and the quality of their information.</p>
  <p><strong>7C Panel: Citizen Science and Disasters: The Case of OpenStreetMap &#8211; </strong></p>
  <p>Robert Soden (University of Colorado, Boulder) described the GFDRR project of Open Cities to collect data for resilience planning and explained the reasons to select OpenStreetMap to use for it. Kathmandu is recognised as at risk place, and there was an aim to identify schools that are at risk, but there was a need to do the basic mapping. There was a local partnership with universities in the area. There was a challenge of figuring out data model &#8211; number of stories, usage, roof type, wall type, age. There was a need to make students to collect information that will help in modelling the risk. They produced a lot of training material. The project was successful in collecting the data and enriching the information. The process helped in creating an OpenStreetMap community out of it, and then they launched a local NGO (Kathmandu Living Labs). Trust in the data was important and there was a risk of discrediting the data &#8211; to deal with that, they involved targeted users early as well as spot check the data and done a fuller assessment of the data. They launching similar projects in Jamaica. Vietnam and Madagascar. They want to engage people in more than just data collection, and how they can be support to grow the community</p>
  <p>Mikel Maron (Humanitarian OpenStreetMap Team) Mikel covered what is OpenStreetMap (OSM), the OSM foundation is a different entity than Wikimedia, which is confusing. OSM are a very wide community of many thousands of people that continue to contribute. Humanitarian OpenStreetMap Team (H.O.T) is following the &#8216;Cute Cat theory for humanitarian maps&#8217; &#8211; use something that is alive and people are used to contribute to, when you need it in emergency situations. OSM is used in many organisation and projects in government. Attempts to map all these organisations is challenging. In Bangladesh, there are 6 OSM projects and require cooperation between agencies &#8211; at least all projects contribute to the same database. Organisations find it challenging that they need to support but can&#8217;t control. Starting from Gaza in 2009, OSM community started to map the area although there was no specific request. OSM was eventually used to create local tourist map. The community in Gaza didn&#8217;t continue &#8211; providing long term support is difficult.Haiti 2010 helped in producing the data and it was difficult to coordinate, so that led to the tasking manager. MapGive is providing support through imagery to the crowd &#8211; a way to support OSM by utilising the DigitalGlobe database. There are development of linking OSM and citizen science. There is very rich data in OSM and there is need to understand social science and data research.</p>
  <p><strong>8E Symposium: <a href="http://programme.exordo.com/cs2015/delegates/presentation/91/">Ethical Dimensions of Citizen Science Research</a></strong><br />
  Caren Cooper opened with a list of issues: participation vs exploitation; beneficence, maleficence, autonomy and justice; incentives vs manipulation; IP and data ownership; data misuse, sharing accessiblity; opennes vs privacy and security; cultural competence. <img class="alignright" style="margin:2px;" src="https://pbs.twimg.com/media/B9rTwPsCEAABPQT.jpg:large" alt="" width="392" height="294" /></p>
  <p>Holly Menninger led <a href="http://www.yourwildlife.org/">yourwildlife.org</a> &#8211; the project that she focusing on &#8211; home microbiom at home. Asking dust samples from home that volunteers share and they look at the content. Volunteers want to understand their home but also the science. There was the issue of reporting back to participants &#8211; They want to understand the information, and they provided some information and it was a challenge to translate the scientific information into something useful. People are interested in the information at home, sometime due to personal issues &#8211; e.g. request to get the results because someone is ill in the house. There is a lag of 2 years between samples and results, and it need to be explained to the participants. There is also an issue that the science is exploratory, which mean that there are no specific answers that can be answered for participants.</p>
  <p>Madhusudan Katti explored the appropriation of citizens knowledge. In the realm of IP in traditional knowledge is discussed a lot. Appropriating local knowledge and then publishing when the information came from local knowledge through interviews &#8211; but the scientists get the fame. Collecting information about engendered species where there is risk from local community. he mentioned the film <a href="https://www.youtube.com/watch?v=MWcdMjv41ho">Living with elephants</a> which focus on the conflicts between humans and elephants but that also might help poachers.</p>
  <p>Janet Stemwedel highlighted that even participant-led citizen science can be helped with DIY science. DIY science it is self efficacy, and control the process, so if the participants running the show, than what can go wrong? Who better to protect my autonomy than me? The answer that autonomy is tricky and need good information about potential risks and benefits and your current choices can hurt future prospects for choosing freely (don&#8217;t use autonomy to get addicted, or what you do with your personal information), finally our exercise of autonomy can impact others&#8217; prospects of free choice (DNA analysis have an impact on your wider family). Institutional Research Board (IRB) is a mechanism to think it through &#8211; potential consequence (good and bad), who could be impacted? strategies for answering the question. Reasons to resist IRB &#8211; not legally required, and the academic scientists complain about it, as well as no access to an IRB.</p>
  <p>The reason to get over the resistance is that unintentional harm is not a good thing, also to get feedback from more eyes helped to know about tools and approach. Ethical objectivity is to go beyond just gut feeling and discuss with other people.</p>
  <p>Anne Bowser discussed the ethics of gamification &#8211; the use of game design elements in non-game contexts (using leader boards). Old weather had an element of games, and also the floracaching as an example. There is labour/exploitation too &#8211; in games such as Civilization II is done for fun, while you learn about history. Online games are using different approaches to extract more from their users. Does contribution to science cleanse the ethical issues because it&#8217;s not for motives? crowdsourcing was critique in different ways. There are also tracking and privacy, so it also provide habits and all sort of details about the users (e.g. in foursquare) &#8211; salesforce is getting badges to encourage people to act in specific ways as employees. Ethical citizen science: treat participants as collaborators; don&#8217;t waste volunteer time; volunteers are not computers (<a href="http://crowston.syr.edu/content/purposeful-gaming-socio-computational-systems-citizen-science-design-case">Prestopnik &amp; Cowston 2012</a>). Ethical design allow participants to be aware of the implication and decide if they want gamification or not.</p>
  <p>Lea Shanley &#8211; covering data privacy &#8211; her awareness came from working with Native American tribes, with participatory mapping. Tribes started to use participatory GIS. There were many things they wanted to map &#8211; and the participants had difference in views about sharing the data or not. Some places were careful and some was not. In disaster response, there is all the social media curation, and many people that are open data evangelist and they started sharing location of first aiders location and actually risking them. In citizen science, there is lack of attention to location &#8211; places were they recorded, and even real time information that risk physical security of participants. Face recognition is possible. Information collected by volunteer can reveal medical information that can harm people prospects. sensitive information, sacred sites location, endangered species. Toxic environments can risk volunteers. There are also issues with who interpret and manage the data. social norms and reinforcing social norms. An emerging area is security of social media &#8211; crowdsourcing teams where hacked in DARPA red balloon challenge. There can be issues with deliberate hacking to citizen science from people who don&#8217;t like it.</p>
  <p>Dianne Quigley &#8211; N<a href="http://www.brown.edu/research/research-ethics/neep">ortheast Ethics Education Partnership</a>, that came from issues of environmental and social justice to improve ethical knowledge of researchers. When researchers start with a community they start with discussion of risk/benefits and consider who is getting something out of it. Training graduate students to know how to work with communities. avoid harming &#8211; non-maleficence; also informed consent of working with communities, protecting data; justice is a way to think of linguistic diversity, respect to local knowledge, and also recruitment in a fair way in terms of representation. Data management and protocols. There is a need to learn humility &#8211; to respect the needs and practices of the community.</p>
  <p>There are ideas to start an ethics group in the CSA and consider code of ethics or participant bill of rights. do we need to extend IRB oversight? co-created common rule? is there a value in code of ethics or will it be a dead word? The discussion explored the need bottom up projects which also need to consider the impacts and outputs, communication with the public and promising what the research will deliver, and the investment of time in citizen science by early career researchers can also impact their career prospect. These are challenges that are common in community participatory research.</p>
  <p>9A Panel: <a href="http://programme.exordo.com/cs2015/delegates/presentation/167/"><strong>The brave new world of citizen science: reflecting critically on notions of citizenship in citizen science</strong></a></p>
  <p>The panel is specifically reflecting on the citizenship aspects of citizen science. Citizen science is a significant phenomena, and feeling that need a critical voice within it. What is the place of the citizen in citizen science? question about governance, methodologies practices and methodologies. How does it connect to wider democratisation of knowledge?</p>
  <p>Eugenia Rodrigues (University of Edinburgh, UK) asked: what model of citizenship it promotes? one way is to look at the demographics, but we can ask about the term &#8211; possible to use volunteer, amateur, or extended peer community (as in Post-Normal Science). The term citizen include autonomy, creativity, liberty , responsibility, having a stake and other meaning. What are the citizens doing and are we constructing a story that recognises the citizen scientists as a citizen? The story that is appearing in work in North-east of England dealing with water pollution in local woodland, where they noted that the Environment Agency was not doing things satisfactory way, so their need of their local habitat was overlooked. In this case  we have contextual/experiential knowledge and expert monitoring skills to lead to a change. Citizen science can be seen as counter expertise. We need to include &#8211; some classification are trying to control the role of the citizens, the need to control levels of participation to improve quality, do not give space for participants to exercise their citizenship fully.</p>
  <p>Shannon Dosemagen (Public Lab) &#8211; in public lab there are specific attention to environmental monitoring and there is a need to re-imagine the role. In public lab they prefer to use civic science or community science and not citizen science because it can be controversial or different in different places. They also think of scientists and non-scientists not in a supplicant way. Consider how engage people in the whole process. Different roles play out in different ways &#8211; they want to be active about it. There are different roles within the community of public lab but it is about egalitarian approach to roles?</p>
  <p>Esther Turnhout (Wageningen University) looking at expertise and quality control in citizen science networks for biodiversity knowledge. Biodiversity knowledge is existing in amateur naturalists and they started using the term citizen science. To conceptualise &#8211; there are complex relationships with mainstream science. Biodiversity recording been around for a long time and the data is increasing demand for decision making. What it brought with it is demand to professionalise and increase standards and quality. The validation is the complex networks of amateurs, experts, professionals and decision makers &#8211; looking at actors in the network. Validation is done in different places with different motivations &#8211; there are hierarchical network inside the naturalists groups and enforcing them with novices. The digitise data is compared with existing observation and there is reciprocity between observer and the process of collecting and organise the data. There are lots of things &#8211; butterflies, community of observers, the field guide &#8211; the process is circular. But increasingly, validation is imposed and procedural. Validation seizes to be collective and the records no longer circulate. The main concern is to keep check where the data go and belong to the observer. The citizenship dependent on not just turning the data into probabilities. There is a need to maintain control over the data.</p>
  <p>Rick Hall (Ignite!, UK) there been different learned societies around the country &#8211; the learned societies that emerged from the 18th century, the acts of enclosures and the workhouses enslaved large groups in society. Today, we can ask about Internet barons if they are trying to do the same as mill owners. There is a cultural entitlement in the human right declaration. The current president of the Royal Society &#8211; finding things for yourself is at the very heart of science. It matter where it takes place &#8211; for example in a popup shop that allows community curiosity labs and explore questions that matter to them. Spaces in schools that young people can take ownership over their investigations. In spaces like Lab_13 are spaces to learn how to become a scientist. The issues are asking young people what people want to know know. We need spaces where citizens learn not just science but how to become scientists&#8230; We need more community and civic citizen scientists because the world need more curios minds.</p>
  <p>Erinma Ochu (University of Manchester, UK) &#8211; as a neuroscientist she found her research that it requires empathy and stories as a way the science evolved as powerful and controlling. What happen when you bring science to the public realm? How to ensure that it is inclusive for women and minorities?</p>
  <p>For me, the discussion highlighted that it was mostly about collective action and egalitarianism in the production of knowledge -so expertise without hierarchy.</p>
  <p>another observer raised the issue of democratisation and what notion of political actions we would like to see within citizen science</p>
  <p>The final keynote was from Amy Robinson <strong>EyeWire: Why Do Gamers Enjoy Mapping the Brain? </strong>demonstrating the game and how it works. Lessons from EyeWire &#8211; it&#8217;s been running for 2 years and a lot of things that were learned. The idea: if we build it, they will play &#8211; that&#8217;s not happen. Actually, carefully crafted, slowly built community &#8211; creating the tools, learning about how things are used. Media is crucial &#8211; 60% of eyewire registration came within 5 days of major media event. Major media event is in facebook, twitter and other social media &#8211; suddenly things are coming from media. Facebook page can convert viewers to participants. Media relations are an active engagement, not just waiting for journalist &#8211; share all sort of things, and funny things. Reaching out to media also require being prepared to it &#8211; and you need to cope with it and capture it. Create internal analytics to understand how the project works. Engagement is also a major issue &#8211; there is a huge drop off after two months. By creating games and missions can provide a reason to capture people&#8217;s interest. Prestige within the community can work to motivate them &#8211; changing the user handle colour can demonstrate the recognition by the project. There are also specific challenges and set their own challenges. Accuracy and efficiency &#8211; using the power players in the game to have a bigger role in the project. How do you recognise a potential power players in your game? Design of the entry page is critical &#8211; the page is minimalist and reduce the amount of information that you need to enter the system. They have created all sort of interesting collaboration such as fascinating visualisations. There is also need to take risks and see if they are going to work or not.</p>
  <p>Abe Miller-Rushing close the conference asking people to share talks and links, as well as posters will come online. We are aiming to create a community and serve the needs. The new board chair, Greg Newman continue with some take aways from the conference which completed the conference.</p>

  <p><strong>The Association of American Geographers is coordinating an effort to create an <a href="http://www.aag.org/cs/encyclopedia">International Encyclopedia of Geography</a></strong>. Plans started in 2010, with an aim to see the 15 volumes project published in 2015 or 2016. Interestingly, this shows that publishers and scholars are still seeing the value in creating subject-specific encyclopedias. On the other hand, the weird decision by Wikipedians that <a href="http://en.wikipedia.org/wiki/Geographic_information_science">Geographic Information Science</a> doesn&#8217;t exist outside GIS, show that geographers need a place to define their practice by themselves. You can find more information about the AAG International Encyclopedia project <a href="http://www.esri.com/news/arcnews/spring12articles/developing-the-international-encyclopedia-of-geography.html">in an interview with Doug Richardson from 2012</a>.</p>
  <p>As part of this effort, I was asked to write an entry on &#8216;<strong>Volunteered Geographic Information, Quality Assurance</strong>&#8216; as a short piece of about 3000 words. To do this, I have looked around for mechanisms that are used in VGI and in Citizen Science. This are covered in <a href="https://povesham.wordpress.com/2014/08/14/openstreetmap-studies-and-why-vgi-not-equal-osm/">OpenStreetMap studies</a> and similar work in GIScience, and in the area of citizen science, there are reviews such as the one by Andrea Wiggins and colleagues<a href="http://crowston.syr.edu/system/files/PID2090593.pdf"> of mechanisms to ensure data quality in citizen science projects</a>, which clearly demonstrated that projects are using multiple methods to ensure data quality.</p>
  <p>Below you&#8217;ll find an <strong>abridged version of the entry (but still long)</strong>. The citation for this entry will be:</p>
  <p>Haklay, M., Forthcoming. Volunteered geographic information, quality assurance. in D. Richardson, N. Castree, M. Goodchild, W. Liu, A. Kobayashi, &amp; R. Marston (Eds.) <em>The International Encyclopedia of Geography: People, the Earth, Environment, and Technology</em>. Hoboken, NJ: Wiley/AAG</p>
  <p>In the entry, I have identified 6 types of mechanisms that are used to ensure quality assurance when the data has a geographical component, either VGI or citizen science. <strong>If I have missed a type of quality assurance mechanism, please let me know!</strong></p>
  <p>Here is the entry:</p>
  <h3>Volunteered geographic information, quality assurance</h3>
  <p><a href="http://en.wikipedia.org/wiki/Volunteered_geographic_information">Volunteered Geographic Information (VGI)</a> originate outside the realm of professional data collection by scientists, surveyors and geographers. <strong>Quality assurance of such information is important for people who want to use it</strong>, as they need to identify if it is fit-for-purpose. <a href="http://www.sciencedirect.com/science/article/pii/S2211675312000097">Goodchild and Li (2012)</a> identified three approaches for VGI quality assurance , ‘<em>crowdsourcing</em>‘ and that rely on the number of people that edited the information, ‘<em>social</em>’ approach that is based on gatekeepers and moderators, and ‘<em>geographic</em>’ approach which uses broader geographic knowledge to verify that the information fit into existing understanding of the natural world. In addition to the approaches that Goodchild and li identified, there are also ‘<em>domain</em>’ approach that relate to the understanding of the knowledge domain of the information, ‘<em>instrumental observation</em>’ that rely on technology, and ‘<em>process oriented</em>’ approach that brings VGI closer to industrialised procedures. First we need to understand <strong>the nature of VGI and the source of concern with quality assurance</strong>.</p>
  <p>While the term volunteered geographic information (VGI) is relatively new (Goodchild 2007), the activities that this term described are not. Another relatively recent term, <a href="http://en.wikipedia.org/wiki/Citizen_science">citizen science</a> (Bonney 1996), which describes the participation of volunteers in collecting, analysing and sharing scientific information, provide the historical context. While the term is relatively new, the collection of accurate information by non-professional participants turn out to be an integral part of scientific activity since the 17th century and likely before (Bonney et al 2013). Therefore, <strong>when approaching the question of quality assurance of VGI, it is critical to see it within the wider context of scientific data collection and not to fall to the trap of novelty, </strong>and to consider that it is without precedent.</p>
  <p>Yet, this integration need to take into account the insights that emerged within geographic information science (GIScience) research over the past decades. Within GIScience, it is the body of research on <strong>spatial data quality</strong> that provide the framing for VGI quality assurance. Van Oort’s (2006) comprehensive synthesis of various quality standards identifies the following elements of spatial data quality discussions:</p>
  <ul>
  <li><strong>Lineage</strong> – description of the history of the dataset,</li>
  <li><strong>Positional accuracy</strong> – how well the coordinate value of an object in the database relates to the reality on the ground.</li>
  <li><strong>Attribute accuracy</strong> – as objects in a geographical database are represented not only by their geometrical shape but also by additional attributes.</li>
  <li><strong>Logical consistency</strong> – the internal consistency of the dataset,</li>
  <li><strong>Completeness</strong> – how many objects are expected to be found in the database but are missing as well as an assessment of excess data that should not be included.</li>
  <li><strong>Usage, purpose and constraints</strong> – this is a fitness-for-purpose declaration that should help potential users in deciding how the data should be used.</li>
  <li><strong>Temporal quality</strong> – this is a measure of the validity of changes in the database in relation to real-world changes and also the rate of updates.</li>
  </ul>
  <p><strong> While some of these quality elements might seem independent of a specific application, in reality they can be only be evaluated within a specific context of use.</strong> For example, when carrying out analysis of street-lighting in a specific part of town, the question of completeness become specific about the recording of all street-light objects within the bounds of the area of interest and if the data set includes does not include these features or if it is complete for another part of the settlement is irrelevant for the task at hand. The scrutiny of information quality within a specific application to ensure that it is good enough for the needs is termed ‘<strong>fitness for purpose</strong>’. As we shall see, <strong>fit-for-purpose is a central issue with respect to VGI</strong>.</p>
  <p>To understand the reason that geographers are concerned with quality assurance of VGI, we need to recall the historical development of geographic information, and especially the historical context of <a href="http://en.wikipedia.org/wiki/Geographic_information_system">geographic information systems (GIS) and GIScience</a> development since the 1960s. For most of the 20th century, geographic information production became professionalised and institutionalised. The creation, organisation and distribution of geographic information was done by official bodies such as national mapping agencies or national geological bodies who were funded by the state. As a results, <strong>the production of geographic information became and industrial scientific process</strong> in which the aim is to produce a standardised product – commonly a map. Due to financial, skills and process limitations, products were engineered carefully so they can be used for multiple purposes. Thus, a topographic map can be used for navigation but also for urban planning and for many other purposes. Because the products were standardised, detailed specifications could be drawn, against which the quality elements can be tested and quality assurance procedures could be developed. <strong>This was the backdrop to the development of GIS, and to the conceptualisation of spatial data quality</strong>.</p>
  <p>The practices of centralised, scientific and industrialised geographic information production lend themselves to quality assurance procedures that are deployed through organisational or professional structures, and explains the perceived challenges with VGI. Centralised practices also supported employing people with focus on quality assurance, such as going to the field with a map and testing that it complies with the specification that were used to create it. In contrast, <strong>most of the collection of VGI is done outside organisational frameworks</strong>. The people who contribute the data are not employees and seemingly cannot be put into training programmes, asked to follow quality assurance procedures, or expected to use standardised equipment that can be calibrated. The lack of coordination and top-down forms of production raise questions about ensuring the quality of the information that emerges from VGI.</p>
  <p><strong>To consider quality assurance within VGI require to understand some underlying principles that are common to VGI practices</strong> and differentiate it from organised and industrialised geographic information creation. For example, some VGI is collected under conditions of <strong>scarcity</strong> or <strong>abundance</strong> in terms of data sources, number of observations or the amount of data that is being used. As noted, the conceptualisation of geographic data collection before the emergence of VGI was one of scarcity where data is expensive and complex to collect. <a href="https://povesham.wordpress.com/2014/01/10/assertions-on-crowdsourced-geographic-information-citizen-science-1/">In contrast, many applications of VGI the situation is one of abundance</a>. For example, in applications that are based on micro-volunteering, where the participant invest very little time in a fairly simple task, it is possible to give the same mapping task to several participants and statistically compare their independent outcomes as a way to ensure the quality of the data. Another form of considering abundance as a framework is in the development of software for data collection. While in previous eras, there will be inherently one application that was used for data capture and editing, in VGI there is a need to consider of multiple applications as different designs and workflows can appeal and be suitable for different groups of participants.</p>
  <p>Another underlying principle of VGI is that since the people who collect the information are not remunerated or in contractual relationships with the organisation that coordinates data collection, a <strong>more complex relationships between the two sides are required</strong>, with consideration of incentives, motivations to contribute and the tools that will be used for data collection. Overall, <strong>VGI systems need to be understood as socio-technical systems in which the social aspect is as important as the technical part</strong>.</p>
  <p>In addition, <strong>VGI is inherently heterogeneous</strong>. In large scale data collection activities such as the census of population, there is a clear attempt to capture all the information about the population over relatively short time and in every part of the country. In contrast, because of its distributed nature, VGI will vary across space and time, with some areas and times receiving more attention than others. An interesting example has been shown in temporal scales, where some citizen science activities exhibit ‘weekend bias’ as these are the days when volunteers are free to collect more information.</p>
  <p>Because of the difference in the organisational settings of VGI, a different approaches to quality assurance is required, although as noted, in general such approaches have been used in many citizen science projects. Over the years, several approaches emerged and these include ‘<em>crowdsourcing</em> ‘, ‘<em>social</em>’, ‘<em>geographic</em>’, ‘<em>domain</em>’, ‘<em>instrumental observation</em>’ and ‘<em>process oriented</em>’. We now turn to describe each of these approaches.</p>
  <p>The<strong> ‘<em>crowdsourcing</em>’</strong> approach is building on the principle of abundance. <strong>Since there are is a large number of contributors, quality assurance can emerge from repeated verification by multiple participants</strong>. Even in projects where the participants actively collect data in uncoordinated way, such as the OpenStreetMap project, it has been shown that with enough participants actively collecting data in a given area, the quality of the data can be as good as authoritative sources. The limitation of this approach is when local knowledge or verification on the ground (‘ground truth’) is required. In such situations, the ‘<em>crowdsourcing</em>’ approach will work well in central, <a href="https://povesham.wordpress.com/2010/07/10/the-tyranny-of-place-and-openstreetmap/">highly populated or popular sites where there are many visitors</a> and therefore the probability that several of them will be involved in data collection rise. Even so, it is possible to encourage participants to record less popular places through a range of suitable incentives.</p>
  <p>The<strong> ‘<em>social</em>’</strong> approach is also building on the principle of <strong>abundance in terms of the number of participants, but with a more detailed understanding of their knowledge, skills and experience</strong>. In this approach, some participants are asked to monitor and verify the information that was collected by less experienced participants. <a href="http://www.plosbiology.org/article/info%3Adoi%2F10.1371%2Fjournal.pbio.1001220">The social method is well established in citizen science programmes such as bird watching</a>, where some participants who are more experienced in identifying bird species help to verify observations by other participants. To deploy the social approach, there is a need for a structured organisations in which some members are recognised as more experienced, and are given the appropriate tools to check and approve information.</p>
  <p>The<strong> ‘<em>geographic</em>’</strong> approach uses <strong>known geographical knowledge to evaluate the validity of the information that is received by volunteers</strong>. For example, by using existing knowledge about the distribution of streams from a river, it is possible to assess if mapping that was contributed by volunteers of a new river is comprehensive or not. A variation of this approach is the use of recorded information, even if it is out-of-date, to verify the information by comparing how much of the information that is already known also appear in a VGI source. Geographic knowledge can be potentially encoded in software algorithms.</p>
  <p>The<strong> ‘<em>domain</em>’</strong> approach is an extension of the geographic one, and in addition to geographical knowledge <strong>uses a specific knowledge that is relevant to the domain in which information is collected</strong>. For example, <a href="http://www.computer.org/csdl/proceedings/e-science/2012/4467/00/06404472-abs.html">in many citizen science projects that involved collecting biological observations</a>, there will be some body of information about species distribution both spatially and temporally. Therefore, a new observation can be tested against this knowledge, again algorithmically, and help in ensuring that new observations are accurate.</p>
  <p>The<strong> ‘<em>instrumental observation</em>’</strong> approach remove some of the subjective aspects of data collection by a human that might made an error, and <strong>rely instead on the availability of equipment that the person is using</strong>. Because of the increased in availability of accurate-enough equipment, such as the various sensors that are integrated in smartphones, many people keep in their pockets mobile computers with ability to collect location, direction, imagery and sound. For example, images files that are captured in smartphones include in the file the GPS coordinates and time-stamp, which for a vast majority of people are beyond their ability to manipulate. Thus, the automatic instrumental recording of information provide evidence for the quality and accuracy of the information.</p>
  <p>Finally, the<strong> ‘<em>process oriented</em>’</strong> approach bring VGI closer to traditional industrial processes. Under this approach, <strong>the participants go through some training before collecting information, and the process of data collection or analysis is highly structured</strong> to ensure that the resulting information is of suitable quality. This can include provision of standardised equipment, online training or instruction sheets and a structured data recording process. For example, volunteers who participate in the <a href="http://www.cocorahs.org/">US Community Collaborative Rain, Hail &amp; Snow network (CoCoRaHS)</a> receive standardised rain gauge, instructions on how to install it and an online resources to learn about data collection and reporting.</p>
  <p>Importantly, <strong>these approach are not used in isolation and in any given project it is likely to see a combination of them in operation</strong>. Thus, an element of training and guidance to users can appear in a downloadable application that is distributed widely, and therefore the method that will be used in such a project will be a combination of the process oriented with the crowdsourcing approach. Another example is the <a href="http://www.openstreetmap.org/">OpenStreetMap project</a>, which in the general do not follow limited guidance to volunteers in terms of information that they collect or the location in which they collect it. Yet, a subset of the information that is collected in OpenStreetMap database about wheelchair access is done through the highly structured process of the <a href="http://wheelmap.org/">WheelMap application</a> in which the participant is require to select one of four possible settings that indicate accessibility. Another subset of the information that is recorded for humanitarian efforts is following the social model in which the tasks are divided between volunteers using the <a href="http://tasks.hotosm.org/">Humanitarian OpenStreetMap Team (H.O.T) task manager</a>, and the data that is collected is verified by more experienced participants.</p>
  <p>The final, and <strong>critical point for quality assurance of VGI that was noted above is fitness-for-purpose</strong>. In some VGI activities the information has a direct and clear application, in which case it is possible to define specifications for the quality assurance element that were listed above. However, one of the core aspects that was noted above is the heterogeneity of the information that is collected by volunteers. Therefore, before using VGI for a specific application there is a need to check for its fitness for this specific use. While this is true for all geographic information, and <a href="https://povesham.wordpress.com/2014/01/16/assertions-on-crowdsourced-geographic-information-citizen-science-2/">even so called ‘authoritative’ data sources can suffer from hidden biases</a> (e.g. luck of update of information in rural areas), the situation with VGI is that <strong>variability can change dramatically over short distances</strong> – so while the centre of a city will be mapped by many people, a deprived suburb near the centre will not be mapped and updated. There are also limitations that are caused by the instruments in use – for example, the GPS positional accuracy of the smartphones in use. Such aspects should also be taken into account, ensuring that the quality assurance is also fit-for-purpose.</p>

Aus den Ergebnissen lassen sich viele Schlüsse über die Erfassung des Gebiets ziehen wie die Vollständigkeit bzw. Sättigung eines Gebietes mit dem gegebenen Tag, das Spin-off in Form neuen Tag-Diversifizierung wie beispielsweise <code>amenity=hospital</code> → <code>amenity=clinic</code> und die sprunghafte Erhöhung der Anzahl der Tags, wie sie normalerweise zu sehen ist, wenn ein Land in den Fokus des humanitären Mappings gelangt.</li>

Der Atlas wurde unter Verwendung neuer und bestehender Daten erstellt, die in das 2C Geonode Webportal und OpenStreetMap (OSM) hochgeladen wurden. Die lokalen Geodaten, die auf diesen beiden Plattformen gespeichert sind, wurden von Kathmandu Living Labs (KLL) im Rahmen des Secondary Cities (2C) Pokhara-Projekts generiert. Sie arbeiteten direkt mit den Behörden von Pokhara Metropolitan zusammen, um die Mehrheit der Gesundheitsstationen der Stadt, Krankenhäuser, Kliniken, Wasserversorgungsnetze, Radiostationen, Tankstellen, Schulen, Organisationen und Unternehmen auf der Karte zu ergänzen und sie damit zu einer der besten Kartendatenquellen der Stadt werden zu lassen.
