summary:
  When I first started editing OSM, I was mostly doing residential roads and bike trails. Eventually I worked my way to major roads. Some of them had dual carriageways. In my case these were also US/State highways. Somehow I got the two mixed up in my head and thought that mapping any dual carriageway road required relations. Since I didn't know much about relations at the time I was kind of scared to touch them. Turns out relations ARE used to describe highways however they are not required for dual carriageway roads.<br /><br />Since I've recently been working on "dualizing" roads in the Kansas City area, I thought I would throw up a quick post about the process. It has probably already been done (I seem to recall a "TIGER fixup" tutorial that described the process) but here is my version.<br /><br />To Start off with, let's define a dual carriageway road. There may be some difference of opinion (there usually is in OSM) but in general it is any road where the opposing streams of traffic are separated by a <b>physical barrier.</b>&nbsp;A grass median (think interstates) or a strip of trees in the middle of a boulevard are prime examples. Sometimes the barrier is just a small strip of raised pavement or bricks. Regardless, it is something that would make your car go "bump" or even cause damage if you were to try and drive through/over it.<br /><a name='more'></a><br />The Census TIGER data that was imported for all of the US just has a single centerline for any given road. The Census Bureau doesn't care about routing topology. They just want basic road centerlines that they can use to carve the country up into their tracts for statistical purposes.&nbsp;There is a <i>tiger:separated</i> tag that I presume is supposed to indicate dual carriageway roads but I have only seen this set to <i>yes</i> a handful of times so as far as I am concerned, that tag can be ignored.<br /><br />So why bother splitting things up? Well for interstates it is pretty obvious. The ways are far enough apart from each other that you really need to be able to distinguish between the two ways for navigation purposes. They may also be part of different routes (where highways overlap interstates) or have other differentiating characteristics. But even on smaller roads, it can be important detail. For example, see this intersection in <a href="http://www.openstreetmap.org/?lat=38.9668&amp;lon=-94.6764&amp;zoom=12&amp;layers=M">Overland Park</a> (part of the Kansas City metro area):<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://lh4.googleusercontent.com/-CVL1sXHOOh4/TW22gfLhZzI/AAAAAAAAAUg/zZ6TlBMXDuE/s1600/dual_before.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="263" src="https://lh4.googleusercontent.com/-CVL1sXHOOh4/TW22gfLhZzI/AAAAAAAAAUg/zZ6TlBMXDuE/s320/dual_before.png" width="320" /></a></div><br />This is obviously going to cause problems for routing and is likely to set off a flurry of annoying "recalculating" messages in navigation devices if you are trying to go east from that residential road.<br /><br />Medians in the middle of roads are also a visual navigation aid for drivers so having the map show where the road is split is a good thing.<br /><br />Here is another short section of road that I will convert to a dual carriageway. In this case it won't really affect routing very heavily but if we are going to have the best map in the world then we need details!<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://lh6.googleusercontent.com/-JG4hN1sNhqA/TW24l7sZJvI/AAAAAAAAAUk/QIk_mzFp9kI/s1600/dc_before.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="272" src="https://lh6.googleusercontent.com/-JG4hN1sNhqA/TW24l7sZJvI/AAAAAAAAAUk/QIk_mzFp9kI/s400/dc_before.png" width="400" /></a></div><br />The first task is to split the way at the beginning and end of the dual carriageway section and mark the section as a one-way street using the oneway=yes tag. Now adjust the geometry to fit into one lane or the other.<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://lh3.googleusercontent.com/-n2gjo3MExZ4/TW24n_bODsI/AAAAAAAAAUo/kT8pgLAVyhc/s1600/dc_1.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="272" src="https://lh3.googleusercontent.com/-n2gjo3MExZ4/TW24n_bODsI/AAAAAAAAAUo/kT8pgLAVyhc/s400/dc_1.png" width="400" /></a></div><br />You will see that JOSM (as of the style update last week!) puts black arrows along the way to indicate its one-way-ness. Potlatch does something similar.&nbsp;You may need to reverse the direction of the way to make sure the arrows are pointing in the right direction.<br /><br />The next step is to draw in the other side of the road. Then copy the highway=* classification as well as the name and the oneway=yes tag (and possibly other tags, as appropriate) from the old way to the new one. To reduce typo errors, I usually just copy the old way and then paste the tags onto the new one using CTRL+SHIFT+V in JOSM. Then I remove any tags I don't want to duplicate, like all the <i>tiger:</i> tags since my new way is not TIGER data.<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://lh3.googleusercontent.com/-rpJjdYFgQbE/TW24vzF6niI/AAAAAAAAAUw/IIPXV28H5_M/s1600/dc_3.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="272" src="https://lh3.googleusercontent.com/-rpJjdYFgQbE/TW24vzF6niI/AAAAAAAAAUw/IIPXV28H5_M/s400/dc_3.png" width="400" /></a></div><br />You will notice that they look slightly different. The old way still is still tagged with <i>tiger:reviewed=no</i>&nbsp;but the new one doesn't have a tiger:reviewed tag. JOSM renders an extra casing around unreviewed TIGER roads to highlight them. I usually only remove this tag if I have done a thorough survey on the ground. In this case I am just using aerial imagery so I will leave it alone. I also usually try to tag the new way I created with a source&nbsp;tag (<i>source=bing</i> in this case) to indicate where I got this information from. That way if someone has a source that they know is better or more up to date than bing, they can update my work in the future.<br /><br />Finally, I need to fix the connecting road so that the topology is still correct. In this case it actually involves dualizing that road as well.<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://lh6.googleusercontent.com/-4bdd-AIBGT0/TW24zywFVvI/AAAAAAAAAU0/F8Q5xaUcR3U/s1600/dc_after.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="272" src="https://lh6.googleusercontent.com/-4bdd-AIBGT0/TW24zywFVvI/AAAAAAAAAU0/F8Q5xaUcR3U/s400/dc_after.png" width="400" /></a></div><br />In this case I brought the intersecting road to a point on the north way. Depending on the situation I sometimes do this or leave them straight and have two intersection points instead of one. Here I felt like using a single node more closely matched the path a car would actually take to turn from one street onto the other. There is always a balance to be struck between topology, geometry and level of detail.<br /><br />And that's it. Nothing too complicated really. TL;DNR:<br /><br /><ul><li>Split way, tag with oneway=yes</li><li>Draw new way</li><li>Copy name, highway and oneway tags to new way</li><li>Fix intersecting roads</li><li>PROFIT! (optional)</li></ul>On the miles long roads I've been working on in Kansas City I often make several passes back and forth, mapping additional things like traffic lights (highway=traffic_signals) which can be identified from pavement markings and shadows on the ground (obviously only if imagery is good enough).<br /><br />Some intersections take a bit of work. Here is a pretty complex one involving US 69, College Boulevard, on/off ramps and a couple of bridges for good measure.<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://lh5.googleusercontent.com/-NMveoBHr28c/TW3EWtr9ELI/AAAAAAAAAU4/1Jlk4YXiMyE/s1600/dc_motorway.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="331" src="https://lh5.googleusercontent.com/-NMveoBHr28c/TW3EWtr9ELI/AAAAAAAAAU4/1Jlk4YXiMyE/s640/dc_motorway.png" width="640" /></a></div><br />Here is a simple one but it involves a smaller road that splits right before it intersects the big road:<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://lh5.googleusercontent.com/-ysntuuMD_PU/TW3GIb06UvI/AAAAAAAAAU8/HyaN_R_EeUo/s1600/dc_residential.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="320" src="https://lh5.googleusercontent.com/-ysntuuMD_PU/TW3GIb06UvI/AAAAAAAAAU8/HyaN_R_EeUo/s320/dc_residential.png" width="276" /></a></div><br />And as the last image for this post, I give you the rendered version of the area I used as an editing example:<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://lh6.googleusercontent.com/-cch9oXtiknQ/TW3YWIQACCI/AAAAAAAAAVA/aWZGIJVi6lg/s1600/dc_rendered.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="275" src="https://lh6.googleusercontent.com/-cch9oXtiknQ/TW3YWIQACCI/AAAAAAAAAVA/aWZGIJVi6lg/s320/dc_rendered.png" width="320" /></a></div><br />That's all!

summary:
  In my <a href="http://ksmapper.blogspot.com/2011/01/airports-part-1.html">first installment</a> of the airport series I presented some basic mapping techniques I used while mapping rural airports in Kansas. One comment I got on IRC suggested using a slightly different tagging scheme for displaced thresholds. The suggestion (I believe it was from pnorman) was to tag it with two tags. One being aeroway=runway and the other being runway=displaced_threshold. While I haven't gone back and changed my previous work, this may be a better way of doing it. First of all, they would get rendered on the default map. I know, I know... "<a href="http://wiki.openstreetmap.org/wiki/Tagging_for_the_renderer">don't tag for the renderer</a>!" But here's the thing: This is technically not incorrect. Displaced thresholds are considered part of the runway and are included when the runway length is specified. So tagging it as a runway but then specifying that it is a specific type of runway is not incorrect tagging. On standard maps it would be rendered as part of the runway but someone making an aeronautical themed map could use the runway=displaced_threshold tag to differentiate it and produce a customized rendering.<br /><br />Before I go on, I am just going to repost a link to the OSM wiki page for <a href="http://wiki.openstreetmap.org/wiki/Airport">Airports </a>as a reference.<br /><br />Now on to some new material. I was moving west-to-east through Kansas so the first "big deal" airport I came to was the Salina Municipal Airport. Its 17/35 runway is a massive 12,300 feet (3.8 kilometers) long. Any aircraft currently in service could land here with room to spare. Why does a municipal airport in a city of under 50,000 people in the middle of Kansas have such a massive runway? The military, of course! This facility was built at the beginning of World War II and was used to train heavy bomber crews. Then during the cold war it became part of Strategic Air Command operations until it was closed and turned over to the city of Salina in 1965. (source: <a href="http://en.wikipedia.org/wiki/Schilling_Air_National_Guard_Base">wikipedia</a>) Now it serves mostly general aviation but is also used by Kansas State University's aviation program which is based at the Salina campus. A few years ago it was used by Steve Fossett as the start and end point of his solo, nonstop flight around the globe. And I got to bill them for the telecommunications services they used while doing it! (My current day job deals a lot with the telecom billing system at KSU)<br /><br />I promise, I'll get to the mapping in this post, eventually. But I should point out that this is one thing I love about contributing to OSM. Seeing something unusual in aerial imagery can often lead to an hour spent on wikipedia or a fun discussion on IRC involving people from around the world or, occasionally, a field trip to go see what the heck is happening "on the ground" to cause it to show up a certain way in aerial imagery.<br /><br /><a name='more'></a><br /><br />Back to Salina: I had two sets of aerial imagery that conflicted slightly about the length of one of the runways. (USGS and Bing) Obviously the images were taken at different times. But which was newer? Bing imagery has metadata that is sent with each tile that can sometimes tell you when it was taken. In JOSM you can display this metadata by right clicking without moving the mouse. A menu pops up with a "Show Tile Info" option. Unfortunately in most of the areas I have worked in, it usually says something like it did in this case: "capture-date: 2/1/1995-3/15/2007." So that's useless. While reading the <a href="http://en.wikipedia.org/wiki/Salina_Municipal_Airport">wikipedia page</a> about the Salina airport,&nbsp;I noticed a link down in the "External links" section pointing to an FAA "<a href="http://naco.faa.gov/d-tpp/1101/00362AD.PDF">airport diagram</a>" in a PDF. I clicked on it... and just like that I had found a new source of data to use while mapping! Since this is federal government data that is intended for public distribution, I believe it is public domain so license isn't an issue. And yes, this is only for airports in the US. My apologies to the rest of the world.<br /><br /><div class="separator" style="clear: both; text-align: center;"></div>These diagrams are constantly updated by the FAA. They have the basic layout of the airport. Turns out the Salina airport shortened the 12/30 runway for some reason so that answered my aerial imagery question. But the diagram also has information about the taxiways. Unused ones are X'd out and the ones that are still in use have their names specified. That can go into the ref=* tag of the taxiways just like runway numbers. One thing to note however is that these are "diagrams" not "maps." So they can not be relied on for accurate cartography. Buildings are usually just squares and do not represent the true proportions or shape of the building. So use with caution - just like any other external data source.<br /><br />Here is the <a href="http://www.openstreetmap.org/?lat=38.79443&amp;lon=-97.64998&amp;zoom=15&amp;layers=M">Salina airport</a> with its enormous runway:<br /><br /><div class="separator" style="clear: both; text-align: center;"></div><div class="separator" style="clear: both; text-align: center;"><a href="http://3.bp.blogspot.com/_RA5iXwXMupA/TUdUkRV9aSI/AAAAAAAAATs/mPdZLbHAC-8/s1600/salina_map.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="320" src="http://3.bp.blogspot.com/_RA5iXwXMupA/TUdUkRV9aSI/AAAAAAAAATs/mPdZLbHAC-8/s320/salina_map.png" width="214" /></a></div><br />Other information that can be taken from the FAA PDF files include location of the control tower and runway width which can go in a width=* tag. Looking at the contents of existing width tags, it doesn't look like there is currently any support for specifying units so I guess everything should probably be in meters. (Everything should be in meters anyway. Everywhere. But that's another debate for another blog)<br /><br />It seems there are two ways to map the control tower. One being aeroway=control_tower and the other (documented on the wiki) being man_made=tower/service=aircraft_control. Currently they seem to have about the same usage (both&nbsp;minuscule&nbsp;- about 50 instances) but I think I personally prefer aeroway=control_tower. That keeps airport features together in the same tag. Also, man_made=tower seems to be more for things like cell phone or radio towers. An aircraft control tower is typically a building that happens to be tall and sometimes skinny.<br /><br />As I said above, I found this particular FAA diagram via Wikipedia. When I went back to try and find diagrams for other airports I ran into all kinds of old information, broken links and just plain bad design on faa.gov. So to save you the pain, here is a link directly to where you can start a search for airports in your state:&nbsp;<a href="http://avn.faa.gov/index.asp?xml=aeronav/applications/d_tpp">http://avn.faa.gov/index.asp?xml=aeronav/applications/d_tpp</a>&nbsp;First you have to select the date range, then click on a state. Then you can search by airport code, city name or airport name. Not every airport has a diagram but certainly all major ones do. Go forth and tag!<br /><br />Another interesting document from the FAA is<a href="http://www.faa.gov/air_traffic/publications/atpubs/aim/Chap2/aim0203.html">&nbsp;Airport Marking Aids and Signs</a>. This is just a document showing exactly what all the little lines/blocks/arrows/signs/etc at an airport mean.<br /><br />The next major airport I hit was Mid-Continent Airport in Wichita. It already had some pretty good coverage but I added ref=* tags for all the runways and taxiways using the FAA diagrams. The Wichita airport has a few more taxiways than usual because it has both Learjet and Cessna facilities adjacent to the airport and they are all connected by taxiways. &nbsp;Because the previous mapper also used the source=* tag, I knew it was based on Yahoo imagery so I also improved the level of detail according to the high resolution Bing imagery available here.<br /><br />Two new features I identified at this airport: parallel runways and terminal buildings. If runways are named based on magnetic heading then what happens for parallel runways? Turns out this is handled pretty simply. Just tack "R" and "L" to the end of it based on which one is to the right and which one is to the left as you are approaching the runway to land. So one runway is named 1L/19R and the other 1R/19L.<br /><br />Terminal buildings aren't too hard either. In this case, there is a main airport building and two wings that extend to the east and west. These wings are where the gates are. Since I have been to this airport before, I know they are simply referred to "East Concourse" and "West Concourse." The previous mapper had done it as a single huge polygon with a building=yes tag. I decided to split it up int 3 parts so that I could name the concourses. I added an aeroway=terminal tag to the two concourses. Technically I believe there is a difference between a "terminal" and a "concourse" but the distinction seems a little hazy in common usage and depending on airport design. OSM doesn't seem to have anything mapped as a concourse so I just stuck with terminal. Anyway, here is the finished product:<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="http://1.bp.blogspot.com/_RA5iXwXMupA/TUYQ1IPQYUI/AAAAAAAAATU/29-VpA4rST8/s1600/ICT.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="284" src="http://1.bp.blogspot.com/_RA5iXwXMupA/TUYQ1IPQYUI/AAAAAAAAATU/29-VpA4rST8/s320/ICT.png" width="320" /></a></div><br />The couple of times I have embarked on bigger projects like this on OSM, I tend to start out mapping basics. As I go I find more details to map and by the end I'm doing some serious micro-mapping and worrying about sub-meter offsets in aerial imagery. In this case, these tendencies were worsened by the increasingly good resolution of aerial imagery as I moved into the urban areas of eastern Kansas. The last airport I touched was Kansas City International airport. Yes, it is in Missouri. But it is in the part that was robbed from Kansas by the pesky meandering of the Missouri river. Also, it was within the simple square bounding box I used to download airport nodes from the XAPI.<br /><br />Again, a lot of features were already basically there but were traced from old Yahoo imagery. Having flown out of this airport multiple times, I was able to use my own local knowledge to augment the aerial imagery. For example, the original imagery had a good bit of radial distortion and it was hard to distinguish the terminal buildings from the large overhang that covers the sidewalk in front of them so the buildings were lopsided and not uniform like I know them to be in reality. Here is a "before" shot I got from OpenCycleMap before it had a chance to re-render:<br /><div class="separator" style="clear: both; text-align: center;"><a href="http://4.bp.blogspot.com/_RA5iXwXMupA/TUZJbidfL8I/AAAAAAAAATY/_0R3jrwGI9I/s1600/KCI_before.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="252" src="http://4.bp.blogspot.com/_RA5iXwXMupA/TUZJbidfL8I/AAAAAAAAATY/_0R3jrwGI9I/s320/KCI_before.png" width="320" /></a></div><br />Not horrible at this zoom level but when viewing it in JOSM with z21 aerial imagery, it looked a lot worse. I found this airport to be kind of fun to work on and ended up adding more and more detail over a period of a couple of days. With large operations like this and high resolution imagery, you can pretty much add as much detail as you want, especially if you have some local knowledge to add to the imagery. So here is what I did with the terminals:<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="http://2.bp.blogspot.com/_RA5iXwXMupA/TUb0dvs4EpI/AAAAAAAAATc/Gihi5wqzsJI/s1600/KCI_terminal_closeup.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="249" src="http://2.bp.blogspot.com/_RA5iXwXMupA/TUb0dvs4EpI/AAAAAAAAATc/Gihi5wqzsJI/s320/KCI_terminal_closeup.png" width="320" /></a></div><br />I used the architecture to my advantage and placed nodes in the&nbsp;columns&nbsp;of the building where straight segments connect at an angle to make a curved building. Here you can clearly see the large overhang in front of the building that somewhat confused the previous mapper.<br /><br />One area that wasn't mapped very well were the long term parking lots north of the airport as well as the buses that take you from long term parking to the terminals. Again, my local knowledge combined with the high resolution aerial imagery let me pick out a lot of features. For example, bus stops, tagged highway=bus_stop and shelter=yes since they are small enclosed huts to protect travelers from the wind that usually blows from some direction around here.<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="http://2.bp.blogspot.com/_RA5iXwXMupA/TUb2SDlBffI/AAAAAAAAATg/0kn_i_b4nW0/s1600/KCI_bus_stop.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="317" src="http://2.bp.blogspot.com/_RA5iXwXMupA/TUb2SDlBffI/AAAAAAAAATg/0kn_i_b4nW0/s320/KCI_bus_stop.png" width="320" /></a></div><br />Then of course there are the parking aisles (highway=service/service=parking_aisle) which in this case can also be tagged as oneway=yes since you can clearly see the angled parking stalls. Also, there are dedicated bus service roads leading from the parking lots to the main road to the airport. Access to these roads is restricted to buses only and enforced by lift gates. The roads are tagged &nbsp;tagged&nbsp;highway=service/access=private and the lift gates,&nbsp;barrier=lift_gate/access=private. This is where a restricted bus route enters a parking area through a lift gate:<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="http://4.bp.blogspot.com/_RA5iXwXMupA/TUb41K9eI2I/AAAAAAAAATk/zqC6KC5NnGE/s1600/KCI_liftgate.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="310" src="http://4.bp.blogspot.com/_RA5iXwXMupA/TUb41K9eI2I/AAAAAAAAATk/zqC6KC5NnGE/s320/KCI_liftgate.png" width="320" /></a></div><br />Then of course there are the parking areas themselves. These were already present but I refined them and added some more tags. Currently they are tagged with this: amenity=parking/parking=surface/fee=yes to indicate that this is a surface (as opposed to underground or garage) parking lot and that a fee is charged for parking here. The result is this map of the long-term parking area:<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="http://3.bp.blogspot.com/_RA5iXwXMupA/TUb6JGo2CDI/AAAAAAAAATo/7pmNnLOuBpM/s1600/KCI_parking_map.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="233" src="http://3.bp.blogspot.com/_RA5iXwXMupA/TUb6JGo2CDI/AAAAAAAAATo/7pmNnLOuBpM/s400/KCI_parking_map.png" width="400" /></a></div><br />One useful thing I need to add is either a name or ref tag for the parking areas. I know they are named to&nbsp;correspond&nbsp;with the terminals (A, B, C) and you are supposed to park in the lot that is named the same as the terminal you will be flying out of (for bus routing reasons) but I don't recall which is which off the top of my head. Guess it's time for a trip to some place exotic so I can survey the airport parking lot on the way there.<br /><br />The short term parking in the center of the terminal buildings can be tagged similarly but with "parking=multi-storey" instead of "surface" to indicate that these are multi-level parking garages. They aren't rendered any differently though. There are also walkways that cross a small bridge from the top of the parking garage to the streets in front of the terminal buildings. Here is a view of one of the terminals:<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="http://1.bp.blogspot.com/_RA5iXwXMupA/TUd1cNnvvWI/AAAAAAAAAT4/jHaFSYaq6TM/s1600/kci_terminal_B.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="320" src="http://1.bp.blogspot.com/_RA5iXwXMupA/TUd1cNnvvWI/AAAAAAAAAT4/jHaFSYaq6TM/s320/kci_terminal_B.png" width="299" /></a></div><br />Notice the "B" in the middle of the parking area. That is the name of this terminal building. This is kind of a bug in the Mapnik rendering software in my opinion. I believe it uses a "center of gravity" algorithm for determining where to place polygon labels. In this case, the center of gravity of the building is outside of the building outline. Oops.<br /><br />The last bit of micro-mapping involved the grassy areas between the runways/taxiways. The wiki page mentions that they can be mapped as landuse=grass so I thought I'd give it a shot and see how it turned out. The result seems pleasing to the eye however it is a fair a mount of effort. Although I personally find mapping just about anything at zoom level 21 is kind of fun. Like this:<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="http://3.bp.blogspot.com/_RA5iXwXMupA/TUdp--Z8jfI/AAAAAAAAATw/w-d2WSWeQCw/s1600/kci_windsock.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="185" src="http://3.bp.blogspot.com/_RA5iXwXMupA/TUdp--Z8jfI/AAAAAAAAATw/w-d2WSWeQCw/s200/kci_windsock.png" width="200" /></a></div><br />Yes, I found a windsock in aerial imagery. And of course there is a tag for it! aeroway=windsock - and there are currently 280 of them in the database. JOSM even renders a little red/white striped cone on a little stick! However it is not rendered in the default map styles on osm.org.<br /><br />After adding a few more features like fences where I could clearly make them out (barrier=fence) and gates (barrier=gate) as well as the drainage ditches, (waterway=drain) here is the <a href="http://www.openstreetmap.org/?lat=39.30273&amp;lon=-94.71051&amp;zoom=15&amp;layers=M">Kansas City International Airport</a>:<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="http://1.bp.blogspot.com/_RA5iXwXMupA/TUdrR1LqSYI/AAAAAAAAAT0/6oKSVqKoC2I/s1600/kci_map.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="320" src="http://1.bp.blogspot.com/_RA5iXwXMupA/TUdrR1LqSYI/AAAAAAAAAT0/6oKSVqKoC2I/s320/kci_map.png" width="233" /></a></div><br />The main thing I'm not really happy about is the road classification. When I started, everything in the area was tagged as highway=residential, as imported from TIGER. I upgraded the major road coming in to the airport to trunk since it is basically built like an interstate. Even some of the roads inside of the security perimeter of the airport had been imported from TIGER. These I changed to highway=service and added access=private. The main circle that goes to all three terminals is marked as tertiary. This all seems fine. The terminal roads themselves are very low speed (I think the sign says 15 mph) but also very wide. There are two 3-lane roads separated by an island in the middle for taxis and hotel buses and such. They seem too big to be called a service road. I left them classified as residential for now but this doesn't seem quite right either. Same with the roads leading to the long term parking lots. Suggestions are of course welcome. :)<br /><br />One thing I haven't touched on is gates. They can be mapped by tagging a node with aeroway=gate and ref=* to indicate the gate number. I have no source of gate names/locations so for now I ignored them. I was also unsure about how to map them. One airport I looked at had lone gate nodes floating out in the apron, essentially where the airplane would sit to dock at the gate. While this kind of makes sense from the pilot's perspective, I might argue that gates should probably be mapped at the edge of the terminal building or even inside the building to make them of use to passengers wanting to find out where they need to go in the airport to find their gate.<br /><br />And one last note: there are a good number of adjacent features (mostly apron/terminals/landuse) that share nodes with each other right now in my work at the Kansas City airport. These should probably be converted to use multipolygons as node sharing is often frowned upon for this kind of thing and is indeed somewhat harder to deal with in some instances. That's the way it was mapped when I got there. My edits made the map better. Not perfect. Yet.<br /><br />And so concludes my great Kansas airport mapping adventure. Thanks for flying!

summary:
  For the past few days I've gone on an airport binge in&nbsp;<a href="http://www.openstreetmap.org/">OpenStreetMap</a>. I ended up learning a lot about airports. It was fun to start mapping, then come across something different or notice a new detail and realizing that this too can be mapped! Here are my musings on the subject. Feel free to tell me I did it all wrong in the comments :)<br /><br />The recent import of airport nodes from&nbsp;<a href="http://www.ourairports.com/">www.ourairports.com</a>&nbsp;and the subsequent discussion sparked the idea to map&nbsp;easily identifiable runways from aerial imagery. So I downloaded all "aeroway=aerodrome" nodes within Kansas from the XAPI. In addition to the above mentioned import, a lot of airports were imported from USGS GNIS (Geographic Names Information System) back in early 2009. In total there were just under 600.<br /><br />This being Kansas, a vast majority of those 600 "airports" are nothing more than a flat spot in a field where farmer Joe lands his crop duster. They have such names as "Lundgren Hereford Ranch Airport" or "Flying N Ranch Airport." They should probably be downgraded from "aerodrome" to something else and not rendered at zoom level 10 like they are now. Right now looking at <a href="http://www.openstreetmap.org/?lat=38.676&amp;lon=-101.259&amp;zoom=10&amp;layers=M">western Kansas at z10</a> reveals a ridiculous number of airports being rendered. I have yet to see any consensus on a tagging scheme for smaller airports so I mostly just ignored them. Additionally, the aerial imagery I was using (USGS NAIP) wasn't really good enough to reliably pinpoint these grass strips in the middle green fields. It also didn't help that the GNIS information is often off by quite a bit so I wasn't sure if the runway was just blending in or if there really wasn't one in the field I was looking at but rather 2 fields over.<br /><br />The more interesting airports are the municipal air fields. Most of these have a paved runway, sometimes in addition to a grass one. Even small airports stick out when they have a paved runway:<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="http://2.bp.blogspot.com/_RA5iXwXMupA/TSU5rRGp71I/AAAAAAAAAS0/gGV_ldvt0QA/s1600/small_airport.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="300" src="http://2.bp.blogspot.com/_RA5iXwXMupA/TSU5rRGp71I/AAAAAAAAAS0/gGV_ldvt0QA/s320/small_airport.png" width="320" /></a></div><br /><a name='more'></a><br /><br />This is pretty easy to map. One runway, 3 taxiways and an apron. A quick look at the&nbsp;<a href="http://wiki.openstreetmap.org/wiki/Airport">Airport page</a>&nbsp;on the OSM wiki will tell you to use the aeroway=* tag with values of runway, taxiway and apron. However upon closer inspection, there is a little bit more information that can be extracted:<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="http://1.bp.blogspot.com/_RA5iXwXMupA/TSU8ZsBwVTI/AAAAAAAAAS4/MKNIqsvUv4M/s1600/small_runway.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="249" src="http://1.bp.blogspot.com/_RA5iXwXMupA/TSU8ZsBwVTI/AAAAAAAAAS4/MKNIqsvUv4M/s320/small_runway.png" width="320" /></a></div><br />That big number 17 on the pavement must mean something, right? I have known that runways have names for a long time. But I never knew what they meant.&nbsp;Maybe this is already common knowledge to some people but it turns out they are based on nothing more than which direction the runway points. The runway above has a heading of 173 degrees. Round that to the nearest 10 and chop off the zero and you get 17. The exception to this naming rule is that there is no zero. Runways that point within 5 degrees of north are named 36. But since each runway has two ends, it also has two names obviously separated from each other by 180 degrees. So this is actually runway 17/35. This goes in a ref=* tag on the way that represents the runway. One catch: This is based on the <b>magnetic</b> north pole, not the geographic one. So in theory these can change over time as the magnetic pole moves. Luckily down south here magnetic and geographic poles aren't too far apart and the magnetic pole only moves about 0.1 degrees per year. However up in northern Canada they actually do use the geographic pole for runway numbering because the declination is ridiculously large. I'm sure you will thank me for this information next time you are flying in northern Canada.<br /><br />Update: One of the first readers of this post&nbsp;(petschge on IRC)&nbsp;&nbsp;pointed out that the magnetic pole shift has actually affected at least one major airport:&nbsp;<a href="http://www2.tbo.com/content/2011/jan/05/060831/shift-of-earths-magnetic-north-pole-impacts-tampa-/news-money/">Tampa International</a><br /><br />Next, notice the lines extending across the taxiways a couple hundred feet from the edge of the runway. Kind of hard to make out in this picture but they are there. These are the holding positions where airplanes must stop and wait for permission to enter the runway. In OSM these are tagged with aeroway=holding_position. They are not rendered on the default map style but it is still useful information.<br /><br />Well that's done. The other thing that could be mapped is the buildings and the outline of the airport land. I did map buildings on some airports but not this one. The land area I found difficult to determine from aerial imagery. It was hard to tell if I was looking at an area of mowed grass that belonged to the airport or a field of soybeans so I left the airports as single nodes for now. The final product: (the airport name isn't actually rendered at this zoom level. That "Russell" is from the city boundary around the airport. And I just noticed now that the city boundary probably also defines the outline of the airport. Hindsight!)<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="http://4.bp.blogspot.com/_RA5iXwXMupA/TSaS_JCShZI/AAAAAAAAAS8/vU8XNFNTzH4/s1600/russell_airport.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="320" src="http://4.bp.blogspot.com/_RA5iXwXMupA/TSaS_JCShZI/AAAAAAAAAS8/vU8XNFNTzH4/s320/russell_airport.png" width="213" /></a></div><br />Side note: I was surprised and somewhat disturbed by how many cemeteries I saw immediately next to airport runways in rural Kansas. It kind of makes sense from a landuse perspective. You can't put tall buildings next to a runway. Plus, the local residents won't repeatedly call city hall to complain about the noise. But still, it seems kind of disconcerting in a slightly&nbsp;humorous&nbsp;way.<br /><br />Next up:<br /><div class="separator" style="clear: both; text-align: center;"></div><div class="separator" style="clear: both; text-align: center;"><a href="http://4.bp.blogspot.com/_RA5iXwXMupA/TSaY2oSnmGI/AAAAAAAAATE/LSGpJi1B4uo/s1600/displaced_threshold.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="320" src="http://4.bp.blogspot.com/_RA5iXwXMupA/TSaY2oSnmGI/AAAAAAAAATE/LSGpJi1B4uo/s320/displaced_threshold.png" width="313" /></a></div><br />Ok, we've got the runway which will be named 17/35 again. The taxiway with the holding position, check. But what's this business with the big arrows and the runway start line not being... well... at the <b>start&nbsp;</b>of the runway?! That's what I asked on IRC. User&nbsp;stevensn had the answer. It is called a "displaced threshold." What's that? To&nbsp;<a href="http://en.wikipedia.org/wiki/Runway">Wikipedia</a>! Turns out a displaced threshold is a section of the runway which can be used for planes to start their takeoff roll but it can <b>not</b>&nbsp;be used to land on. In this case, there is a prison just south of the runway. Presumably it has tall fences or walls which means the glide slope for approach to this runway is too high to safely hit the beginning of the runway.<br /><br />This setup also makes me&nbsp;conjure&nbsp;up images of a low flying airplane dropping a bungee cord into the prison yard to yank someone out. Probably impractical due to airspeed and g-force limitations but I'm sure Hollywood could stuff it into a movie somehow. If they do, I want royalties! There <b>have</b>&nbsp;however been several successful (and some failed) helicopter jailbreaks. Google it for fun some time.<br /><br />Anyway, back to mapping. There is no guidance on how to map displaced thresholds on the OSM wiki. Using the&nbsp;<a href="http://taginfo.openstreetmap.de/keys/aeroway">TagInfo</a>&nbsp;tool I looked around and noticed that there were about 15 existing uses of &nbsp;"aeroway=displaced_threshold" tags. This seemed pretty logical to me so that's what I used. Now there are almost 40 uses of this tag. Unfortunately the renderers don't know about it so it doesn't show up on the map but as with holding positions, it is still useful information and if enough of them get mapped we might be able to convince the renderers to add support for it. The only real problem is when a taxiway connects to a displaced threshold. On the map it looks like the taxiway just ends in the middle of nowhere. But this is a rendering problem and remember, in OSM we tag for what's on the ground,&nbsp;<a href="http://wiki.openstreetmap.org/wiki/Tagging_for_the_renderer">not the renderer</a>!<br /><br />And finally (for now) two more new things I learned about:<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="http://3.bp.blogspot.com/_RA5iXwXMupA/TSa0UdW563I/AAAAAAAAATI/T80dMVMzSeM/s1600/overrun.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="299" src="http://3.bp.blogspot.com/_RA5iXwXMupA/TSa0UdW563I/AAAAAAAAATI/T80dMVMzSeM/s320/overrun.png" width="320" /></a></div><br />The yellow chevrons might appear to be similar to the displaced threshold but of course aviation tends to be a very precise business so each splash of paint is precisely regulated to mean something distinct. Going back to the wikipedia page on <a href="http://en.wikipedia.org/wiki/Runway">runways</a>, we see that these are "Blast pads, also known as overrun areas or stopways" and are constructed to take the brunt of the hot air blast when jet engines throttle up for takeoff so that the ground doesn't get eroded. Their construction may not be as robust as the rest of the runway so aircraft are prohibited from using this area for any purpose except in emergencies.<br /><br />Blast pads/overruns/stopways are also not documented in OSM. Once again, I looked at&nbsp;<a href="http://taginfo.openstreetmap.de/keys/aeroway">TagInfo</a>. There were a few that are tagged as aeroway=stopway and a few more that were tagged as aeroway=overrun. So I picked the more popular one. If someone has a compelling argument that it should be stopway or blast_pad I would not object to changing it. The same issue exists with not being rendered as described above for displaced thresholds although it isn't as critical since active taxiways will not connect to this section of the runway.<br /><br />Lastly, note the yellow X marks to the left of the runway. This isn't too hard to figure out. It means the runway/taxiway is not in use. It could be temporary, due to construction, or (as is the case here) permanent closure with the possibility of obstacles/damage present which would make landing here dangerous. I tended to not map these. There were a few that were already mapped as active runways/taxiways so I retagged them aeroway=runway_disused/taxiway_disused which I also found used in TagInfo.<br /><br />I am going to cut this post off here before it gets so long that no one will ever read it. Tune in again soon to see part 2. It will focus on some of the bigger airports and some data sources that I found to help map them in more detail.<br /><br /><b>&lt;ding&gt;&nbsp;</b>This is your Kansas mapper speaking. You are now free to move about the planet but we ask that you leave your GPS device turned on at all times. We hope you enjoy the resulting map. Thank you for choosing OpenStreetMap. Have a nice day.<br /><br />Update: <a href="http://ksmapper.blogspot.com/2011/01/airports-part-2.html">Here is part 2</a>!

summary:
  <i>For a full history of this post you may want to read these three posts first:&nbsp;<a href="http://ksmapper.blogspot.com/2010/10/tiger-ways-in-kansas.html">1</a>,&nbsp;<a href="http://ksmapper.blogspot.com/2010/10/couple-more-tiger-maps.html">2</a>&nbsp;and&nbsp;<a href="http://ksmapper.blogspot.com/2010/11/nationwide-tiger-map.html">3</a>.</i><br /><br />When I first presented my nationwide TIGER map&nbsp;at wherecamp5280,&nbsp;<a href="http://blog.samat.org/">Samat</a>&nbsp;mentioned that he was surprised that his county wasn't more heavily edited since he has done a lot of work there. A few days ago we were chatting on IRC (#osm on oftc.net) and he asked a question that made me realize that the map did indeed have a serious flaw in it. Earlier today a <a href="http://lists.openstreetmap.org/pipermail/talk-us/2010-December/004973.html">discussion </a>came up on the talk-us mailing list that made me notice that the same error exists in the <a href="http://open.mapquestapi.com/tigerviewer/">TIGER edited map</a> that MapQuest (re)set up. So I decided to look at correcting it.<br /><br />The error is that I was only looking at the latest version of the ways. This means that any edits between the original import and the mass edit that expanded street names were not taken into account. Both the import and the abbreviation expansion happened well before I started mapping so I didn't even consider this fact. As Antony Pegg says later in the mailing list thread, it is too expensive to go back and look at all previous versions. Especially since you would have to use a FULL planet file since the regular ones only contain the current version of objects, not a full history.<br /><br />But we don't really care about the contents of the edits or who performed them... we just care that they happened. The initial import obviously created version 1 of the ways and if nothing else changed, then version 2 was created by balrog-kun in the name expansion edit. If any edits happened between the import and the name edit, then the ways will be on version 3 or higher. Thus any TIGER way with a version higher than 2 must have been edited by someone other than these users, even if one of them was the last to touch a way.<br /><br />So here is the updated map which takes this into consideration:<br /><br /><a name='more'></a><br /><br /><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: center;"><tbody><tr><td style="text-align: center;"><a href="http://2.bp.blogspot.com/_RA5iXwXMupA/TQmGQOqPZUI/AAAAAAAAASc/0RdKH1ACiss/s1600/USA_2.png" imageanchor="1" style="margin-left: auto; margin-right: auto;"><img border="0" height="308" src="http://2.bp.blogspot.com/_RA5iXwXMupA/TQmGQOqPZUI/AAAAAAAAASc/0RdKH1ACiss/s400/USA_2.png" width="400" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Click for bigger version</td></tr></tbody></table><br />There are indeed several noticeable differences. For one, Samat's county (Dona Ana, NM) turned two shades lighter! Also, a large chunk of Wyoming came out of the "virtually untouched" classification. The southern tip of Texas as well as the Dallas area lightened up a bit as well. But at the end of the day, there is still a <b>LOT</b> of untouched data out there.<br /><br />This map still isn't perfect. For example, if someone split an imported way, creating a new version 1 way as well as version 2 of the existing one and then the name change edit happened, the new way would be counted as not having been touched by a human. Also, people deleting the tiger:county tag on ways will obviously throw numbers off a little. But this should be much better at least. I'm hoping this change can be incorporated into the MapQuest version as well.<br /><br />For giggles I threw the data up on&nbsp;<a href="http://www.openheatmap.com/view.html?map=InsinuationMaritzasAurelius">OpenHeatMap</a>&nbsp;as well. I'm not sure what happened to Alaska and Louisiana. For some reason OpenHeatMap didn't recognize the county names. It also did its own data classification so it won't match my map exactly. But you can zoom in and mouse over counties and get a pop-up with the name and percentage of unedited ways so that is kind of neat.<br /><br /><b><span class="Apple-style-span" style="font-size: large;">The Data</span></b><br />For your further enjoyment, I am providing the CSV file that was produced as the result of my SQL query. The map is nice and all but some people might want cold hard numbers. I'm thinking some statistical analysis might be interesting. I originally tried to make a graph of the distribution of values but OpenOffice Calc wasn't cooperating that night and I had to pack for a trip so I dropped it.<br /><br /><a href="http://ni.kwsn.net/~toby/OSM/tiger_edited.csv">Click here to download the file.</a><br /><br />The first column is the value from the tiger:county tag. Following that is the percentage of unmodified ways in that county followed by the raw numbers of edited, unedited and total ways. The last three columns were used by me to manipulate the data into an acceptable form to join the data to the shapefile I had. I had to split out state code and county name and then expand the state to its full name using a table I generated from the source of a wikipedia page that lists all states and their abbreviations.<br /><br />I didn't clean it up at all so there are some nonsensical values in there. ArcMap just ignored the values it couldn't match to the shapefile. The first line has a county name of "30 days late" - I have no clue what that is doing in a tiger:county tag. Feel free to do an XAPI request and clean it up! &nbsp;There is also data there for Puerto Rico and D.C. that didn't get matched up. Puerto Rico wasn't in my shapefile and I don't think D.C was correctly matched to the abbreviation.<br /><br />Enjoy!

  <b>Update: </b><i>You should of course still read this post because it is is awesome but there is a new post with an updated version of the map&nbsp;<a href="http://ksmapper.blogspot.com/2010/12/updated-tiger-map.html">here</a>.</i><br /><br />I presented most of this material this weekend at <a href="http://www.wherecamp5280.org/">WhereCamp5280</a>&nbsp;and promised to put this online soon. I have a few more details and maybe some raw data that I will put in another post after I get back home after Thanksgiving but for now I'll throw up what I have.<br /><br />Well after some sweat, blood and tears (mostly on the part of my hard drives) I was eventually successful in extracting the data I needed to make a map of the entire US! If you just want the map feel free to skip down but I am going to document my trials and tribulations a little.<br /><br />First, some things that did <b>not</b>&nbsp;work:<br /><br /><a name='more'></a>Importing the whole planet file into an apidb using osmosis. I actually did this before I made the original Kansas map but it is part of the workflow I went through to get to the final map. The initial response I got on IRC was that it would take maybe 200 GB and a few days, maybe a week. I thought it would be fun to poke around in the database a bit beyond just this map so I decided to try it. I believe the time/space estimate may be accurate for importing to a pgsql database for rendering however I wanted a full apidb. The result:<br /><div class="separator" style="clear: both; text-align: center;"><a href="http://3.bp.blogspot.com/_RA5iXwXMupA/TOOLd9N4wkI/AAAAAAAAARk/PYf0YiEfqmk/s1600/planet_import_disk.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="172" src="http://3.bp.blogspot.com/_RA5iXwXMupA/TOOLd9N4wkI/AAAAAAAAARk/PYf0YiEfqmk/s400/planet_import_disk.png" width="400" /></a></div>Yes, that is 3 weeks. I kept adding disk space to the volume hoping each time that it was almost done. The good news is that ext4's online resizing works great! But after having my heart broken one too many times I went hunting for more information which I probably should have done first. On the mailing list it was pointed out that the size of the main OSM apidb (The Source) is 1.4 TB and while that does include historic data that isn't in the planet file, I realized that I may only half way done so I decided that I needed a different approach.<br /><br />I tried trimming out a rough bounding box for the US which worked. Then I tried filtering out only nodes used in ways since I am only interested in the imported TIGER ways. I was hoping that a lot of the overhead in creating the apidb had to do with having to hit the node table every time a way was inserted due to foreign key constraints and such. I don't have a pretty graph for this attempt but apparently osmosis builds a data structure in memory for every node before filtering out the unused ones. Or something... The end result is that a computer with 16 GB of memory in it was still not enough to finish the job and failed within minutes with an "Out of Memory" exception from osmosis.<br /><br />My last ditch effort was just to import the whole US. I didn't use a fancy polygon to filter, just a straight bounding box that included Alaska and Hawaii so I'm sure I got some extra data (like a good chunk of Canada) but this ended up working... after 80 hours and about to 200 GB.<br /><br /><b>Success!</b><br /><br /><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: center;"><tbody><tr><td style="text-align: center;"><a href="http://3.bp.blogspot.com/_RA5iXwXMupA/TOjC1UD6oXI/AAAAAAAAARo/V02l_xVXK4k/s1600/USA.png" imageanchor="1" style="margin-left: auto; margin-right: auto;"><img border="0" height="307" src="http://3.bp.blogspot.com/_RA5iXwXMupA/TOjC1UD6oXI/AAAAAAAAARo/V02l_xVXK4k/s400/USA.png" width="400" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Click for a bigger version to see those small counties!</td></tr></tbody></table><div class="separator" style="clear: both; text-align: left;">The first thing you might notice is that there are some counties with no data. This is because the TIGER ways in those counties, for one reason or another, do not have tiger:county tags. Some were imported by a user other than DaveHansenTiger and they chose not to import all the TIGER attributes. Some were imported by him but just didn't have the tags. It was suggested at WhereCamp that these may have been the first counties imported and that he may have still been fine-tuning the import process. This seems like a plausible theory.</div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: left;">Other than the missing data, the map makes sense for the most part. The west and northeast coasts are more edited than the center of the country. Large cities are easy to pick out. But there are a few individual counties that do stand out here and there. I'm guessing there are more people like me who have taken an interest in their local area out in the middle of nowhere and have made noticeable contributions to the map. The level of activity in Iowa does seem a little odd. I should single out Iowa and take a look at the data to see if I missed a bot or something. But who knows - it might just be a really motivated Iowan.&nbsp;</div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: left;">Anyway, there you have it. As I said above, there will be another post with some details and data at a later time. Right now I am tired and need to get to bed after spending the day gathering GPS traces on the slopes of Winter Park with Steve, Hurricane, Josh and Richard. It was all for the map - I can assure you that no "fun" was had by anyone!</div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: left;">Well maybe a little.</div>

summary:
  After my last post there were some requests for me to do additional states. So I imported Colorado and New Mexico since they are kind of one big block. However doing 50 states a couple at a time will be rather cumbersome so I think after this I will try to coax osmosis into doing a more fine-tuned import so that I can import only the things I need but do it for the entire US at once.<br /><br />I also learned some more quirks about ArcMap. The program is amazing in some ways but user interface is not one of them. I was also unable to figure out how to use two different fields to join my data to the counties shapefile. So that was slightly frustrating but I was able to work around it.<br /><br />Anyway, until I get around to poking osmosis again,<br /><b><span class="Apple-style-span" style="font-size: x-large;">I give you Colorado:</span></b><br /><a name='more'></a><br /><div class="separator" style="clear: both; text-align: center;"><a href="http://3.bp.blogspot.com/_RA5iXwXMupA/TMkVWaguiqI/AAAAAAAAARQ/pu5IQmNU6WU/s1600/CO_TIGER.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="308" src="http://3.bp.blogspot.com/_RA5iXwXMupA/TMkVWaguiqI/AAAAAAAAARQ/pu5IQmNU6WU/s400/CO_TIGER.png" width="400" /></a></div><br />Colorado has another strong outlier: Teller county with only 35.8% of ways&nbsp;untouched&nbsp;. I didn't look at the data but I believe I know the person responsible for this, in real life even! Hi&nbsp;<a href="http://www.openstreetmap.org/user/SpenSmith">SpenSmith</a>! Also, as you can see I replaced the "total number of TIGER ways proportional symbol with a few city names for general reference.<br /><br /><b><span class="Apple-style-span" style="font-size: x-large;">On to New Mexico:</span></b><br /><div class="separator" style="clear: both; text-align: center;"><a href="http://1.bp.blogspot.com/_RA5iXwXMupA/TMkNVykQV9I/AAAAAAAAARM/amwmDeMn_kA/s1600/NM_TIGER.png" imageanchor="1"><img border="0" height="400" src="http://1.bp.blogspot.com/_RA5iXwXMupA/TMkNVykQV9I/AAAAAAAAARM/amwmDeMn_kA/s400/NM_TIGER.png" width="307" /></a></div><br />Notice the breakdown here. Looking at the data it would seem that either the TIGER data in New Mexico is nearly perfect and requires no editing or New Mexico is a barren wasteland, incapable of sustaining the fragile life force of mappers. There are no outlying counties and the most heavily edited one (Socorro county) is still sitting at almost 90% untouched. And looking at that county closer, I'm guessing it just doesn't have very many roads and all the editing that <b>has</b>&nbsp;been done there is just related to I-25 that runs right through the middle of the county. Of course this is percentages. As far as total number of TIGER ways touched, McKinley and&nbsp;Bernalillo counties win with 877 and 762 respectively.<br /><br /><b><span class="Apple-style-span" style="font-size: x-large;">OpenHeatMap</span></b><br /><b><br /></b><br />Lastly, SeveC pointed me at an interesting website that may be of use once I get my nationwide data lined up:&nbsp;<a href="http://www.openheatmap.com/">http://www.openheatmap.com/</a><br /><br />I went ahead and imported the Colorado data and you can view it here:<br /><a href="http://www.openheatmap.com/view.html?map=FoundlingsFiascoesUngodliest">http://www.openheatmap.com/view.html?map=FoundlingsFiascoesUngodliest</a><br /><br />I found a slight bug in that Broomfield county is missing from OpenHeatMap's database. I chatted with Pete (the admin) about it for a few minutes, until he had to go to participate in an interview for&nbsp;<a href="http://thisweekinmaps.com/">thisweekinmaps</a>.&nbsp;It turns out that he is using census data from 2000 for the county boundaries and Broomfield county <a href="http://en.wikipedia.org/wiki/Broomfield_County#History">didn't yet exist in 2000</a>!&nbsp;I also mentioned to him that it would be nice if state borders were drawn on county based maps and he seemed to agree. There is always <b>something</b>&nbsp;to nitpick, right?

  <b>Update:</b>&nbsp;<i>I have a second post with two more state maps up&nbsp;<a href="http://ksmapper.blogspot.com/2010/10/couple-more-tiger-maps.html">here</a>. More to come!</i><br /><b>Update 2:</b> <i>Here are&nbsp;<a href="http://ksmapper.blogspot.com/2010/11/nationwide-tiger-map.html">two</a>&nbsp;<a href="http://ksmapper.blogspot.com/2010/12/updated-tiger-map.html">more</a>&nbsp;posts with nationwide maps.</i><br /><br />If you are at all familiar with&nbsp;<a href="http://openstreetmap.org/">OpenStreetMap</a>, especially in the US then you will know that most of the roads here are imported from the US Census Bureau TIGER data. This data was imported from the current data in 2007. It is fairly complete but the accuracy leaves a lot to be desired in some areas. For example look at this screen shot comparing the TIGER data to reality (USGS aerial imagery in this case). Some roads are off by over 200 meters. And there are even worse spots - this was just one I was able to find quickly.<br /><br /><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: center;"><tbody><tr><td style="text-align: center;"><a href="http://1.bp.blogspot.com/_RA5iXwXMupA/TMPU8aGq4lI/AAAAAAAAARA/k3QAIUeHl1c/s1600/TIGER_error.png" imageanchor="1" style="margin-left: auto; margin-right: auto;"><img border="0" height="293" src="http://1.bp.blogspot.com/_RA5iXwXMupA/TMPU8aGq4lI/AAAAAAAAARA/k3QAIUeHl1c/s400/TIGER_error.png" width="400" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Example of bad TIGER data</td></tr></tbody></table><br /><br /><br /><div class="separator" style="clear: both; text-align: center;"></div>While the data was pretty complete when it was made, it is now several years old and missing many new housing developments and does not reflect instances where roads were moved. The good news is that, this being a census year, there will be new TIGER data available from the Census Bureau starting at the end of the year. It will be more complete and probably more accurate considering that GPS technology has made some advances over the last 10 years.<br /><br />Well that's great but the question is how do we use the new data to improve OSM? In the software world this would be an ideal situation to use a diff utility to determine what had changed between two versions and apply patches to update the old version. But I am not aware of any geo-spatial diff utilities.<br /><br />So how about just deleting the old data and re-importing the new stuff? This would obviously be a disaster in areas with active mappers. All the work they have put into correcting existing TIGER ways would be destroyed and replaced with data that is probably better than the old TIGER import but also probably worse than what local mappers have done.<br /><br /><b>BUT...</b><br /><br /><a name='more'></a><br /><br />I'm in Kansas. There aren't a lot of mappers here, especially in the western part of the state. Mostly because there just aren't a lot of people out there. Some counties have a population density of 6 people per square mile. Oh and the TIGER data was imported in county sized chunks. So how about handling this on a county-by-county basis? Counties that haven't been touched could just be blown away and refreshed with the new data. If only someone could determine how much TIGER data has changed since the initial import, on a per-county basis... Oh wait, I did!<br /><br />I am taking a cartography class at Kansas State University this semester. After starting to contribute to OSM I decided to take advantage of the employee tuition assistance and learn more about the subject. For $150/semester, why not! 20% of the grade in the class is for a project where he turned us loose to go get our own data and make some kind of interesting map. So I got my data by importing a Kansas extract from the OSM planet file and made this map:<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="http://2.bp.blogspot.com/_RA5iXwXMupA/TMPfanliQRI/AAAAAAAAARE/DcczmV5ffNI/s1600/KS_TIGER_2.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="308" src="http://2.bp.blogspot.com/_RA5iXwXMupA/TMPfanliQRI/AAAAAAAAARE/DcczmV5ffNI/s400/KS_TIGER_2.png" width="400" /></a></div><br />A couple of notes about the map:<br /><br /><ul><li>I let ArcMap classify the data using natural breaks. There are 105 counties in Kansas. 104 of them still have have 78% of their TIGER data in its original state. One has had 75% of it modified. Yes, this is the county I live in. Yes, most of it was done by me. Yes, this inflates my ego.</li><li>The total count doesn't really do much for the map in my opinion but the class project called for a bivariate map, so a bivariate map I made! Obviously counties with bigger cities have more TIGER ways. This is your dose of non-surprise for the day.</li><li>My method of detecting changes by "local" mappers is by no means fool-proof. Basically I looked at the user who last changed a given way. If the user was one of 4 users I identified that were definitely not local mappers, I counted that road as unchanged. (technical details below)</li><li>Labels would add a lot of clutter to the map. If you want to see which counties are which, I suggest the <a href="http://en.wikipedia.org/wiki/Counties_of_Kansas">Counties of Kansas</a> wikipedia page.</li></ul><br />So I guess the question is how do we use this information? This will have to be a discussion amongst the OSM-US community. Due to time limitations I only did Kansas but this could certainly be done for other states (particularly the sparsely populated ones) to help local mappers decide what, if anything, to do with the new TIGER data. My suggestion would be to do a fresh import of any counties that have above a certain threshold of unchanged data. Say 95%? In Kansas that would be 59 counties. If a threshold were decided upon the map classifications could be altered to reflect that number.<br /><br />For counties that HAVE had local activity, perhaps some process could be set up using tiles from the<a href="http://open.mapquestapi.com/tigerviewer/index.html"> TIGER edited map</a> that MapQuest has provided as a background layer in JOSM or P2. Then pull up the new TIGER data on top of it and compare. Import missing roads or ones that are more accurate in the new data and haven't been touched by local mappers. That is just a thought that popped into my head as I was writing this.<br /><br /><b>Technical Details</b><br /><br />I imported the October 20th planet file into an apidb using osmosis. I originally tried to do the whole planet and intended to do a larger analysis of bot activity on a worldwide basis but after 4 weeks and 350 GB &nbsp;it showed no signs of being anywhere close to finished so I fell back to only importing Kansas. Luckily Kansas is pretty much a big rectangle so I just used a simple bounding box. This finished in about 2 hours.<br /><br />Here is the final SQL query I came up with to get me all the data I needed in one result set. Keep in mind that I only imported a bounding box around Kansas:<br /><br /><pre class="source-code">select v as county,<br />sum(CASE WHEN user_id in (147510,7168,20587,293105)<br />    THEN 1 ELSE 0 END) as bot_count,<br />sum(CASE WHEN user_id in (147510,7168,20587,293105)<br />    THEN 0 ELSE 1 END) as user_count,<br />count(*) as total_count<br />from ways, way_tags, changesets<br />where ways.id = way_tags.id<br />and ways.changeset_id = changesets.id<br />and k = 'tiger:county'<br />and v like '%KS%'<br />and v not like '%;%'<br />group by v<br />order by v<br /></pre><br />In less SQLish terms: I am primarily looking at the tiger:county tag to group the query by county. It contains values like "Riley, KS" so basically I am looking for any way with a 'tiger:county=*KS*' tag. This excludes the few ways around the Kansas border that are from other states since my bounding box was just a little bigger than the state borders. However I exclude ways that have multiple values in the tag, separated by a semicolon. Typically this would come from two ways in adjacent counties being joined together. This is pretty rare so I ignored them. Once I find those ways I examine the user who last touched the way by joining through the changesets table. If the user ID is one of 4 values then I count the way as not having been modified by a local mapper. Those 4 user IDs belong to the following users:<br /><ul><li>147510 = woodpeck_fixbot (this is a bot that has performed various automated edits as documented on the OSM wiki)</li><li>7168 =&nbsp;DaveHansenTiger (this is the user who did the initial TIGER import)</li><li>20587 = balrog-kun (this user did some mass editing of TIGER ways by expanding abbreviations in street names)</li><li>293105 = NHD edits&nbsp;(NHD = National Hydrography Dataset. I'm assuming this user probably imported some rivers and ended up splitting some TIGER ways to make bridges or something</li></ul><br /><br />Looking at the data now, I should have maybe also excluded NE2. I believe he has done a lot of work on national highway/interstate routes. I don't think there is any reason to re-import ways that are part of those systems since they have since been added to route relations and such. So those should probably be excluded from the data. Hindsight and all that.<br /><br />Anyway, this query gives me a result like this:<br /><pre class="source-code">county            | bot_count | user_count | total_count<br />------------------+-----------+------------+-------------<br /> Allen, KS        |      3062 |         33 |        3095<br /> Anderson, KS     |      2879 |         64 |        2943<br /> Atchison, KS     |      1235 |         37 |        1272<br /> Barber, KS       |      2173 |         26 |        2199<br /> Barton, KS       |      1764 |        254 |        2018<br /> Bourbon, KS      |      3815 |        137 |        3952<br /> Brown, KS        |       907 |         46 |         953<br />.<br />.<br />.<br /></pre><br />From there I regex'd it into a CSV file and imported it into ArcMap and joined it to the shapefile of Kansas counties that was provided to us. Easy, right?

summary:
  I have avoided creating a blog for years now. I never felt like I had enough important ideas to force upon the world to justify it. That and I assumed I would abandon it at some point and it would become yet another piece of litter along the information superhighway. I'm not convinced that these things have really changed but there have been a few times recently where I did want to post an idea to a more permanent medium than IRC, especially concerning my latest hobby: OpenStreetMap. So here I am, creating a blog on a Friday night.<br /><br />Who knows where it will go but I do hope to post occasional observations concerning OpenStreetMap as well as some open source topics in general (yes, I use Linux) and maybe an occasional note about my job. I work as a developer for Kansas State University. Java with a heavy dose of SQL (Oracle) if you are curious.<br /><br />Now, here is a random picture of me at the end of No-Shave November in 2008. If anyone reading this doesn't know me, it is a horrible first impression because I usually shave. But there you have it.<br /><br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="http://4.bp.blogspot.com/_RA5iXwXMupA/TMJ1YYMHOrI/AAAAAAAAAQM/X9WKfkx3NIE/s1600/PC110635.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="300" src="http://4.bp.blogspot.com/_RA5iXwXMupA/TMJ1YYMHOrI/AAAAAAAAAQM/X9WKfkx3NIE/s400/PC110635.JPG" width="400" /></a></div>

  <p>I have ask myself for some time now how I could have an estimation of the
  completeness of <a href="https://www.openstreetmap.org">OpenStreetMap</a> when
  it comes to ski pistes. I’m certain that with our more than 100’000 km of
  pistes, downhill and cross-country combined, we are the biggest global ski
  pistes database of this type, but what exactly remains to map? I needed
  something to compare to.<br /></p>
  <p>There is this great site called <a href="https://www.skimap.org">Skimap.org</a> where contributors can upload scans and
  photos of ski maps from their favorite ski area. They have more than 3000 ski
  area listed. These ski areas location are crowd-sourced by their contributors,
  and skimap.org offers an open API. So I can certainly find a way to compare
  this with OpenStreetMap data, no ? Yes, so I did. And many thanks to
  Russel for making <a href="https://www.skimap.org">Skimap.org</a> !<br /></p>
  <p>The comparison goes both ways, first there is a long list called
  <strong><a href="http://www.opensnowmap.org/qa/OSM_vs_skimap_missing_at_OSM/">Pistes missing
  from OpenStreetMap.org</a></strong>.<br /></p>
  <p>Then we have a map showing <strong><a href="http://www.opensnowmap.org/qa/OSM_vs_skimap_missing_at_skimap/">Ski areas
  missing in Skimaps.org</a></strong>.</p>
  <p>It’s not perfect, because there are <a href="https://www.openstreetmap.org">OSM</a> ways on one side that are not really
  (or rarely) grouped as ‘ski resorts’ and single points on the other side. So of
  course in some case the distance threshold chosen (5km) is maybe not the best,
  and in some case <a href="https://www.skimap.org">Skimap.org</a> ski area
  localization could be improved.<br /></p>
  <h2>OpenStreetMap ‘ski areas’</h2>
  <p>No, they are not built-in in the <a href="https://www.openstreetmap.org">OSM</a> database. There is the tag
  ‘landuse=wintersports’ to tag ski resorts, but it is seldom used. The rejected
  relation proposal ‘site=piste’ attracts even less contributions.<br /></p>
  <p>So for this comparison they are build in a database like
  this :<br /></p>
  <p><img src="http://blog.opensnowmap.org/public/osm_skimap.png" alt="osm_skimap.png" style="display:block; margin:0 auto;" title="osm_skimap.png, sept. 2018" /><br /></p>
  <p>The pistes from OSM are buffered by 500m, then glued in big polygons. Very
  big polygons (&gt;30km) are split in equal size rectangular chunks ranging from
  20km to 40km. This is a bit arbitrary but allows to more or less efficiently
  separate interconnected ski areas.<br /></p>
  <p>In the end, this gives &gt;3500 downhill ski areas, and the same number of
  nordic skiing areas.</p>
  <h2>What have I found ?</h2>
  <p>First a really good news : both projects contributors can still have a
  lot of fun contributing for a while. <a href="https://www.skimap.org">Skimaps.org</a> excels in the USA, and <a href="https://www.openstreetmap.org">OpenStreetMap</a>.org is better in
  Europe.<br /></p>
  <p>At first glance around 800 ski areas can be found in Skimap.org but not in
  <a href="https://www.openstreetmap.org">OpenStreetMap</a>. For <a href="https://www.skimap.org">Skimap.org</a>, a lot of small and micro downhill
  resorts are missing (apparently &gt; 1500). For nordic skiing, it’s really
  worse, but it’s not really the target audience I guess.<br /></p>
  <p>Also, <a href="https://www.openstreetmap.org">OSM</a> seems more complete
  when it comes to lifts (aerialways) than for ski pistes themselves. I would
  risk an explanation here. There is a lot of gondolas enthusiasts
  (https://www.remontees-mecaniques.net/, http://www.funivie.org/web/,
  Lift-World.info https://lift-world.info/, ...), and I suspect people are
  mapping lifts systematically. Armchair mapping is also possible for aerialways
  on the contrary to ski pistes.<br /></p>
  <h2>How does it helps ?</h2>
  <p>Both project’s data have open license, but not compatible (CC-BY-SA vs
  OdBL). So each can be used for the other as an inspiration, but not as a direct
  data source. Needless to say ski maps uploaded at Skimap.org are for the vast
  majority copyrighted and not be used for mapping at OSM.<br /></p>
  <p>For <a href="https://www.skimap.org">Skimap.org</a> contributors, they can
  use the map produced to spot a ski area in OSM, investigate on the web and find
  documentation of interest for the project. For <a href="https://www.openstreetmap.org">OSM</a> contributors, well, as usual :
  find a place with ski pistes to map, take a train ticket, your gear, GPS and
  go !<br /></p>
  <h2>More</h2>
  <p><a href="https://www.skimap.org">Skimap.org</a> also have some more
  information about its ski areas, for example if they are closed. This could be
  used to spot places in <a href="https://www.openstreetmap.org">OSM</a> where
  some map curating is needed. Also, I spotted on the maps some isolated pistes
  in OSM that looks strange. In short, some idea for ski-related QA in <a href="https://www.openstreetmap.org">OSM</a>.<br /></p>

  <p>It's been a few years since the last statistics about ski pistes mapping in
  Openstreetmap.</p>
  <p>You know it: Openstreetmap has the biggest worldwide skimap available. And
  still growing !</p>
  <p>From today stats:</p>
  <ul>
  <li>Crossountry trails: 67961 km</li>
  <li>Alpine runs : 37287 km</li>
  <li>Lifts: 17647 km</li>
  <li>Sled runs : 1376 km</li>
  </ul>
  <p>While at a slower pace than in the glory years, the length of the ski runs
  mapped in OSM grow every year with several thousand of kilometers. This means
  that there is still some ski pistes to map, and a good question is how
  many ? I'm trying to have some clue in comparing other available ski
  areas-related listings, such as Russel's excellent <a href="http://skimaps.org">Skimaps.org</a>. I'll keep you informed.</p>

  <p>Edit : Ah, it's more than <strong>100'000 km</strong> of ski pistes
  without the lifts now !</p>

  <p>I make no mystery of it: I'm a cross-country skier. I've run alpine skis
  only twice in my life, and definitely prefer the wild and quiet areas where
  you're alone sweating your way in the middle of nowhere. This had had
  consequences on Opensnowmap.org, and I did not spent enough time on downhill
  runs rendering style. It was crowded and definitely not clear enough, but this
  is about to change. Now that the ski season is almost done, I'm rolling out a
  major style change.<br /></p>
  <h3>Alpine runs</h3>
  <p>Downhill ski runs are now cleaner (I hope). Especially transition is
  smoother between pistes mapped as areas and those mapped as ways. At high zoom,
  pistes let a clear view on the contour lines and fade in better on the
  topo-style base map.<br />
  <img src="http://blog.opensnowmap.org/public/OLD-NEW.PNG" alt="OLD-NEW.PNG" title="OLD-NEW.PNG, mai 2017" /></p>
  <h3>Icons</h3>
  <p>The less common pistes type (skitours, snowshoes, sled, and sleigh) are now
  rendered with icons. Curling, ice-stock and hockey icons have been added.<br />
  <img src="http://blog.opensnowmap.org/public/curling_skitour.png" alt="curling_skitour.png" title="curling_skitour.png, mai 2017" /></p>
  <h3>Pistes overlaps</h3>
  <p>Sometimes pistes can be used for several activities, now Opensnowmap is able
  to render piste tagged like <em>piste:type = downhill;sled</em> or other
  combination.<br />
  <img src="http://blog.opensnowmap.org/public/sled_overlap.png" alt="sled_overlap.png" title="sled_overlap.png, mai 2017" /></p>
  <p>I hope this improved map will please you, and you are welcome to make any
  remarks or request improvement <a href="https://github.com/yvecai/mapnik-opensnowmap.org/issues">here</a>.</p>
  <h3>External users</h3>
  <p>As long with the new style, the tiles URLs changes. As your website or app
  uses a proper referer, I am able to contact you with the new URL, of course.
  The URL is http(s)://www.opensnowmap.org/pistes/{z}/{x}/{y}.png.<br />
  <br /></p>
  <p>For the offline users, please note that the monthly .mbt tile set from
  28.04.2017 is the last one available with the old style.</p>

  <p><a href="https://www.opensnowmap.org">OpenSnowMap.org</a> renders ski
  ressorts at zoom 10,11 &amp; 12. For this, it takes either <strong><a href="http://wiki.openstreetmap.org/wiki/Tag:site%3Dpiste">site=piste</a></strong>
  relations or <strong><a href="http://wiki.openstreetmap.org/wiki/Tag:landuse%3Dwinter_sports">landuse=winter_sports</a></strong>
  polygons, and checks what type of pistes they contain (downhill, nordic, sled,
  etc...) in order to display small icons next to the ressort name.</p>
  <p>Until now, these icons where pre-calculated images of all possible
  combinations.They were not so nice, and did not scale well with the big tiles
  used on the <a href="https://www.opensnowmap.org/mobile.html">mobile</a> site.
  So I built a very handy font file, called Ski.ttf, that looks like this:</p>
  <p><img src="http://blog.opensnowmap.org/public/Skki_TTF.png" alt="Skki_TTF.png" title="Skki_TTF.png, fév. 2017" /></p>
  <p>This allows me to use <a href="http://mapnik.org/">Mapnik</a> list-placement
  on <a href="https://github.com/mapnik/mapnik/wiki/TextSymbolizer">TextSymbolizers</a> to
  position the needed icons nicely.</p>
  <p>It will takes some time for the tiles to re-render, so here what it looks
  like:</p>

  <p>When Mapquest layer disappeared, this was a problem for OpenSnowMap: its
  cold colors and less detailed style were great to overlay ski pistes onto. But
  the end of this freely available map forced me to build a simple style with
  plenty of room for ski pistes: the OpenSnowMap Base Snow Map.</p>
  <h3>A winter topo map</h3>
  <p>I used OSM-Bright to start building this style. Using colder colours more
  suited to a winter map, of course I also added relief. In particular, relief
  hillshading led me to desaturate highways to avoid they pops out the shadowed
  side of the hills . Ski pistes are not rendered on this layer, the OpenSnowMap
  remains an overlay. In fact, they *are* rendered on the Base Snow Map with 12
  pixels wide transparent labels that forbids other labels to take place where
  ski pistes from the OpenSnowMap overlay will land.</p>
  <h3>I want to see it!</h3>
  <p>This style is live on opensnowmap.org. The mobile part of the website is
  shown with 'retina tiles' by default, but you can choose this high-dpi option
  or not from the menu. For these mobile-friendly tiles, I choose to render 384px
  tiles and display them with a 1.5x scale factor. That please my eyes on my own
  phone and the server seems to be OK with them, so please tell me they also
  looks good on your phone or tablet.</p>
  <p>Of course, Openstreetmap-carto is still available, although without high-res
  tiles but a simple scaling for the mobile version. Here also let me know what
  the default should be: I find it more usable with the scaling on my device,
  although a bit pixelized.</p>
  <h3>That's great, but ...</h3>
  <p>Unfortunately, the use of the layer outside OpenSnowMap is discouraged by
  referer magic and so on. Also, tiles containing ski pistes are pre-rendered,
  but not the others. So while the Imposm-powered DB is up-to-date and a few
  minutes behind Openstreetmap, don't expect super-performances in tile refresh.
  Yes, 10 minutes so you can check your mapping mistakes and correct them before
  I take them into account, isn't it clever ? This new base map won't change
  much the OpenSnowMap overlay tiles that will remains pretty much the same and
  updated daily.</p>

  <p>Opensnowmap offers overlay tile layers for ski pistes and winter sports. Two
  sets of tiles are available: one with only the pistes, and another one with
  relief background (shaded relief and contours lines).</p>
  <p>It seems that the layer with relief information is of great interest, even
  in summer.</p>
  <p>Sadly, opensnowmap server won't be able to cope well with the demand on next
  winter, so in order to keep the server healthy for skiers, the tile usage
  condition from outside Opensnowmap will change as follow :</p>
  <ul>
  <li>From the 1st of october 2016, a valid referer will be mandatory to fetch
  tiles from www.opensnowmap.org.</li>
  <li>From the 1st of november 2016, access to tiles with relief from outside
  opensnowmap.org is not granted anymore and can stop at any time (likely around
  the 1st).</li>
  </ul>

  <p>When you enter www.opensnowmap.org, there is a small counter that shows you
  the length of ski pistes and lifts there is in OSM each days. On june 6th, the
  total length of alpine and crosscountry ski pistes, skitour, snowshoeing, lifts
  and sleds pistes crossed the 100'000km line.</p>
  <p>Not bad, isn't it ? This number seems important, so I searched and
  found a few flaws in my count, you can find the queries <a href="https://github.com/yvecai/data-opensnowmap.org/blob/master/tools/pistes-stat2json.sh">
  here</a>. I notably found a few thousand of km of crosscountry pistes mapped as
  relations, without pistes tags on ways that were missing on previous
  calculations.</p>
  <p>Anyway, now, we can claim that on 2016-06-06T00:03:02Z, there was
  <strong>108'084 km</strong> of winter sports pistes in Openstreetmap ! Two
  and a half tour of the planet !</p>
  <p>Before OSM, does anybody figured out that there is so many pistes dedicated
  to winter sports on the globe ? And how much is still to be mapped in
  OSM ? Why does some people <a href="http://www.opensnowmap.org/?zoom=14&amp;lat=46.30925&amp;lon=7.09918&amp;layers=mapquest&amp;marker=false">
  map alpine ski pistes as area without a median line</a> that would allow
  routing?</p>

  <p>A new version? Wait ... nothing has changed !</p>
  <p>Well hopefully it's the case. Opensnowmap.org website has been rewrote with
  a cleaner code separating HTML, CSS and Javascript. Also, a few good practises
  in website design have been implemented. For instance there is no blocking
  calls to the server any more.</p>
  <p>There is some changes for the user, though:</p>
  <ul>
  <li>Language change can be done on the fly, no need to reload the page.</li>
  <li>Mobile version has been redesigned a little, allowing you to keep the map
  in view while looking for pistes with the 'Search' input.</li>
  <li>A 'Donate' button landed on the menu, it's not only here to look nice.</li>
  </ul>
  <p>As the code is now cleaner, don't hesitate to propose some changes yourself
  on the website, it's here on <a href="https://github.com/yvecai/opensnowmap.org/">Github</a> . Be kind enough to
  report bugs, I made some tests on a few browsers, but there may things I
  missed.</p>

  major part of the world, resolution jumps to 30m instead of 90m beforehand,
  thanks to the ongoing release of 1 arc-second SRTM data by NASA.</p>
  <p><a href="http://blog.opensnowmap.org/public/30m_-_90m.png"><img src="http://blog.opensnowmap.org/public/.30m_-_90m_m.jpg" alt="30m_-_90m.png" style="display:block; margin:0 auto;" title="30m_-_90m.png, juil. 2015" /></a><br />
  To mak a long story short, the relief is more precise by a x1.5 zoom
  factor.</p>
  <p>For more details, here are the data used on the serveur to generate the
  hillshading.<br />

  <p>30m SRTM data are used where available. Up north, data comes from the EU-DEM
  for scandinavia, ASTER for Alaska, Canada, Greenland and Russia. In an area
  extending from Greece to Iran, I had to kept the 90m SRTM data from CGIAR, I
  hoipe to be able to update this area soon.</p>
  <p>To assemble those datasets, I use a script based on python-gdal to merge the
  data by small 1x1° tiles, filtering SRTM data by a 3x3 average filter and ASTER
  by a 10x10 filter to reduce noise. Gdal utilities then re-assemble everything
  in a big Tiff. For rendering, I took the opportunity to pré-calculate smaller
  Tiff at lower zooms to reduce the load on the tile server. The map should show
  up more fluidly.</p>
  <p>Contour lines will be updated from the same datasets, if I can optimize them
  enough to fit my disks.</p>

  <p>La couche d'ombrage (hillshade) d'OpenSnowMap.org vient de subir un sérieux
  lifting. En effet, sur la plus grande partie du monde, la résolution passe à
  30m au lieu de 90m grâce à la mise à disposition progressive des données SRTM à
  1 seconde d'arc par la NASA (au lieu de 3 secondes précédemment). <a href="http://blog.opensnowmap.org/public/30m_-_90m.png"><img src="http://blog.opensnowmap.org/public/.30m_-_90m_m.jpg" alt="30m_-_90m.png" style="display:block; margin:0 auto;" title="30m_-_90m.png, juil. 2015" /></a><br />
  Pour faire simple, on gagne l'équivalent de 1.5 niveau de zoom pour les
  informations de relief: c'est plus précis.</p>
  <p>Dans le détail, voici les données utilisées par le serveur pour le calcul de
  la couche de relief.<br />
  <img src="http://blog.opensnowmap.org/public/DEM3_coverage.png" alt="DEM3_coverage.png" style="display:block; margin:0 auto;" title="DEM3_coverage.png, juil. 2015" /><br />
  <em>Screenshot from USGS explorer on Google-map background</em></p>
  <p>Les données SRTM 30m sont utilisées là ou elles sont disponibles. Plus au
  nord, il s'agit des données provenant de l'EU-DEM pour la scandinavie, puis
  d'ASTER pour l'Alaska, le Canada, le Groenland et la Russie. Enfin, dans une
  zone s'étirant de la Grèce à l'Iran, les données SRTM 90m sont utilisées.
  J'espère pouvoir profiter là aussi de données à 30m bientôt.</p>
  <p>Afin de réaliser l'assemblage de ces jeux de données différents, je suis
  passé par python-gdal et un script maison pour économiser l'espace disque lors
  du calcul du modéle numérique de terrain global. Dans ce modéle, les données
  SRTM 30m sont filtrées par un filtre médian 3x3 pixels et les données ASTER par
  un filtre 10x10 pixels afin de limiter un peu les artefacts (bruit). Les blocs
  de 1x1° calculés par le script sont traités par les utilitaires gdal pour
  calculer l'ombrage et ré-assembler le tout. Du point de vue du rendu, j'en ai
  profité pour pré-calculer les images de relief aux zooms intermédiaires afin
  d'alléger la tâche du serveur de tuiles, l'affichage de la carte doit désormais
  être plus fluide.</p>
  <p>Les courbes de niveaux seront aussi mises à jour à partir des mêmes données,
  sous réserve de parvenir à les optimiser suffisamment ou de disposer de
  l'espace disque nécessaire.</p>

  <p>Maybe in your favorite resorts, some ski pistes are maintained but not
  groomed. However, they are part of the 'official' and securized piste
  network.</p>
  <p>In openstreetmap, they are called <strong>piste:type=dowhnill</strong> +
  <strong>piste:grooming=backcountry</strong>.</p>
  <p>Now, in OpenSnowMap.org, this is dashed lines, colored by difficulty. What

summary:
  <p>House numbers have been part of mkgmap for a couple of years now, but as more and more housenumbers
  are added to OSM, Gerd undertook a project to update the code to deal with many more cases of real world
  OSM tagging.</p>
  <p>The main changes are:</p>
  <ul>
  <li>mkgmap tries to identify unnamed roads which lead to houses and can be named
  (assuming they are service roads)</li>
  <li>mkgmap tries to find a plausible road when
  no street is given.</li>
  <li><code>addr:interpolation</code> ways are used to find the most plausible road
  and the interpolated addresses are found</li>
  <li>improved evaluation of <code>addr:*</code> tags, esp. the support for <code>addr:place</code> and the 
  support for <code>addr:housenumber</code> without <code>addr:street</code>, 
  img data is optimized to make sure that address search finds a place close (&lt; 40m) to the address. </li>
  <li>special cases regarding addresses in different cities or
  zip codes along the same road are handled. This is important when a road
  starts in city A and has some numbers 1..20 there and later crosses city B with
  numbers 1..5 and finally ends in city C with numbers 1..50.</li>
  <li>the found addresses are typically closer to the house</li>
  </ul>

  <h3>Using in your own style </h3>
  <p>If you want to test with your own style: Please note the new special tags
  <code>mkgmap:numbers=false</code>
  and <code>mkgmap:execute_finalize_rules=true</code></p>
  <ul>
  <li>a road with <code>mkgmap:numbers=false</code> is ignored in house number processing.
  The default style uses this for ferries and motorways and for bicycle-only roads.</li>
  <li>The <code>mkgmap:execute_finalize_rules=true</code> tag will cause the finalize rules to
  be run, even if no object is created in the map for that element.
  So to set the city, region and country values for all elements with house numbers, use<div class="source"><pre><span class="na">addr:housenumber</span><span class="p">=</span><span class="l">*</span> <span class="p">{</span><span class="k">set</span> <span class="n">mkgmap:execute_finalize_rules</span><span class="p">=</span><span class="s">true</span><span class="p">}</span>
  </pre></div>
  as a first rule in points, lines and polygons and add<div class="source"><pre><span class="k">include </span><span class="s1">&#39;inc/address&#39;</span><span class="p">;</span>
  </pre></div>
  to the finalize sections.</li>
  </ul>
  <p>Use version r3612 or above to get these upgrades.</p>

summary:
  <p>From r3366 there are some improvements to the support for driving on the left or right.
  Each tile has a flag to say if roads are drive on the left or right. It is known to
  make a difference with roundabouts and may be used in other ways.</p>
  <p>The options <code>--drive-on-left</code> and <code>--drive-on-right</code> were
  replaced by <code>--drive-on=left</code> and <code>--drive-on=right</code>.
  You can also add <i>detect</i> which will use the country information to select
  the correct side. The default is equivalent to
  <code>--drive-on=detect,right</code> which means that if detection fails, it
  will use drive on the right.
  The old flags <code>--drive-on-left</code> and <code>--drive-on-right</code> still work.</p>
  <p>The detection uses the precompiled bounds (or country-abbr/country-name) to
  determine the country in which the roads are located, and the resource file
  LocatorConfig.xml contains a new attribute driveOnLeft="true" for all known
  drive-on-left countries</p>
  <p>If a tile covers two countries where you drive on different sides of the road, then
  it cannot work for the whole tile and you get a warning. In the future we will be able to cut tiles on country boundaries
  so that the problem will then not arise.</p>

summary:
  <p>There has always been a way to convert a tag
  value from meters to feet, this was originally for contour heights
  which need to be in feet, but the default for OSM is for them to
  be in meters.</p>
  <p>With the release of version r3353 these conversions are much more useful
  and can be applied to speeds as well as lengths. They also take into account
  any unit that is already specified.</p>
  <p>So for example if you specify a conversion of meters to feet,
  then "100" will be converted to "328", "100m" will be converted to "328"
  but "100ft" will be left as "100". Furthermore "100km" would
  result in "328000".
  If any of the units are not recognised then the value remains completely
  unchanged.</p>
  <table class="display">
  <tr>
  <th>Input </th><th> Result</th>

  <tr>
  <td>100 </td><td> 328</td>

  <tr>
  <td>100km </td><td> 328000</td>
  </tr>
  <tr>
  <td>100xyz </td><td> 100xyz</td>

summary:
  <p>A recent change to data in Columbia, South America in Open Street Map
  may cause a problem when creating a map of that area.</p>
  <p>There is a long standing bug in mkgmap that results in a crash when
  compiling the object<a href="http://www.openstreetmap.org/way/313259878">
  http://www.openstreetmap.org/way/313259878</a>
  which is in Columbia. The addr:housenumber is ":702" which triggers
  the bug. Probably that is just a typo and it should be just "702",
  however this should not cause a crash in mkgmap.</p>
  <p>The problem is now fixed in r3354, so you should upgrade if affected
  by this problem. I think you will only see it if using the
  --add-pois-to-areas option.</p>
  <p>Due to the nature of the fix, the resulting .img files may be a little
  smaller than before.</p>

  <p>For quite some time it has been possible to build a map

  <p>Now searching should also work in versions r3294 and later.</p>
  <p>All of Western, Central and Eastern European characters
  should be available as well as Arabic, Greek and various
  others. It is unlikely to work with Chinese characters
  and that will require further investigation.</p>
  <p>Ensure that you are using the options <code>--code-page=65001 --index --route</code>
  as well any others that you need.</p>

  </pre></div>
  </p>
  <p>For backward compatibility you do not have to do this and all existing styles
  should work as they are. However I would recommend that you start to quote all
  arguments that are more complex than a simple word. Before this change it was
  impossible to use a pipe symbol within a regular expression since it would be

summary:
  <p>Splitter now has a new split algorithm that usually results
  in fewer, more evenly sized tiles.</p>
  <p>The test generator is > 10 times faster. This allows a deeper
  search for good splits. A few errors where fixed which
  sometimes prohibited to find a good split, but also sometimes
  helped to find one.</p>
  <p>A new option --search-limit can be used to increase/decrease the
  amount of time the splitter tries to find a good split.
  The larger the input file the higher this value should be.
  For planet, --search-limit=1000000 is okay, --search-limit=10000000
  is better.</p>

  <p>Version r385 of splitter is a large update.</p>
  <p>All the dependent libraries have been upgraded to later versions, so make sure
  that you install the complete package. This might affect you if you don't
  download the complete distribution or install in some unusual way.</p>
  <p>A summary of the visible changes follows:</p>
  <ul>
  <li>Improved error handling: most I/O errors like corrupted or missing
  files will now stop the program instead of just printing error messages,
  and producing a useless result</li>
  <li>Working with pbf files is faster because of the updated libraries.</li>
  <li>Splitting large files is faster because of some improvements in the branch</li>
  <li>Lots of internal changes in the code.</li>

summary:
  <p>The latest version of mkgmap now has much better support for restriction relations.</p>
  <p>Here are the main things that are newly implemented: </p>
  <ul>
  <li>Restrictions that prohibit going between two node via a particular way.</li>
  <li>restrictions no_entry or no_exit</li>
  <li>specific vehicle type, e.g. type=restriction:motorcar or
  restriction:motorcar=no_u_turn</li>
  <li>fixes possible error if different roads connect the same nodes
  (old code possibly saved the restriction for the wrong road)</li>
  <li>detects obsolete restrictions, e.g. when a oneway doesn't allow
  to enter the road or when the restiction applies to motor_vehicles
  only and the road is a cycleway.</li>
  <li>if the style creates multiple routable ways for one OSM way,
  the restriction is added for all needed combinations</li>
  </ul>
  <p>There are a lot of bug fixes too, so it should all work a lot more smoothly.
  Use version r3189 or higher for all the fixes.</p>

summary:
  <p>There have been almost no changes to how mkgmap deals with routing for several
  years now. So I am very happy to announce that the latest version of mkgmap
  now saves much improved routing information to the map. This allows better
  routes to be calculated and over longer distances in many cases.</p>
  <p>Although there are no deliberate backward incompatibilities,
  if you have a heavily customised style, you should carefully examine any 
  workarounds to force particular routing behaviour as it may no longer
  be necessary or may work differently now.</p>
  <p>Also the new version improves the fidelity of features on the map, such
  as roundabouts and parallel lines.
  It happens that positions can only be represented to within 1-2 meters in a Garmin
  map, whereas positions are recorded much more accurately than that within OSM.
  So some approximation is necessary, however this was made worse since mkgmap
  would reduce the precision right at the beginning, allowing errors to build up
  as the data was manipulated. Now the extra accuracy is kept throughout all
  processing until the map data is written and care is taken to preserve angles
  so that lines that are meant to be parallel are more likely to stay that
  way and are less likely to cross or appear to cross.</p>
  <p>Both these improvements were added by Gerd.</p>
  <p>[ <b>Updated</b>: modified to say that roundabouts and parallel lines are a better example of improvement than buildings. Buildings
  will be improved in a subsequent update ]</p>

summary:
  <p>Since r2906 there are some important changes in the style processing which gives the style developer more control about converting OSM elements into the Garmin map elements. As a benefit the routing network is up to 25% smaller which results in faster route calculation and slightly smaller img files.</p>
  <p>Changes in the style system:</p>
  <ul>
  <li>Styles can now have a <tt>&lt;finalize></tt> block. This block is executed for each element if an element style definition matches. The finalize block must contain actions only. This is sometimes useful for general rules and to assign the numerous <tt>mkgmap:*</tt> tags.</li>
  <li>The four labels to pois/lines/roads/polygons are no longer assigned automatically. They must be assigned using the <tt>name</tt> and <tt>addlabel</tt> function. This also means that <tt>ref</tt> tags are no longer used as labels automatically.</li>
  <li>Access restrictions of roads are now defined by setting special <tt>mkgmap:*</tt> access tags (<tt>mkgmap:car, mkgmap:foot, mkgmap:bicycle, mkgmap:truck, mkgmap:bus, mkgmap:taxi, mkgmap:emergency, mkgmap:delivery</tt>). Roads are blocked for a specific vehicle type if the mkgmap:&lt;type> is set to the value <tt>no</tt>. The new <tt>addaccess</tt> and <tt>setaccess</tt> actions help to assign all values at once.
  <pre>
   Example:
   highway=motorway { set mkgmap:foot=no }
   This rule blocks access of pedestrians to motorways.
  </pre></li>
  <li><tt>mkgmap:carpool</tt> does no longer automatically set all access restrictions. In the trunk <tt>mkgmap:carpool=yes</tt> lead to set all access restrictions to <tt>no</tt> except emergency, bus and carpool. It is not fully clear if the bit toggled by mkgmap really controls if a road has a carpool lane or not. So use it with caution.</li>
  <li>The road speed is no longer automatically calculated using the <tt>maxspeed</tt> tag. New style functions <tt>maxspeedkmh()</tt> and <tt>maxspeedmph()</tt> allow to perform the same by setting the <tt>mkgmap:road-speed-class</tt> tag. Due to this change the <tt>--ignore-maxspeeds</tt> option is superfluous and has been removed.</li>
  </ul>
  <p>The changes listed above require a change of all style files. But there are three new include files (<tt>inc/compat_points, inc/compat_lines, inc/compat_polygons</tt>) which ensure compatibility to pre-r2906 releases. They need to be added to the new finalize section.</p>
  <p>Example lines file:</p>
  <pre>
   ...
   boundary=political [0x1c resolution 19]
   
   include 'inc/water_lines';
   include 'inc/contour_lines';
   
   # add the following lines to your lines file
   &lt;finalize>
   include 'inc/compat_lines'; 
  </pre>

summary:
  <p>There are now a number of places where house numbers are well mapped and it
  would be nice to be able to see them on your GPS. In fact this has been a much
  desired feature for a long time now.</p>
  <p>This is now possible, and has been for some time - I suck at getting the news out
  promptly.</p>
  <p>It works with both polish format input files and also with 
  regular OpenStreetMap format files.</p>
  <p>For files in Polish format, the house numbers support is complete and any
  differences from what you were expecting should be reported as a bug.</p>
  <p>For OSM files things are a bit more tricky because there are various systems of
  recording housenumbers used in different parts of the world, and not all of them
  will be recognised.</p>
  <p>For OSM files, you need to add the <code>--housenumbers</code> option to
  get house numbers in the map.</p>
  <p>Of course if there are no numbers in the OSM data in your region then you will
  need to get out and map some to take advantage of this. You will need to add
  <code>addr:street</code> and <code>addr:housenumber</code> to nodes or polygons
  representing the house.</p>

summary:
  <p>Earlier today, mkgmap developer Gerd Petermann merged his changes to create a
  proper overview map into trunk.
  Update now or go and get version r2636 or later from the <a href="/download/mkgmap.html">download page</a>.</p>
  <p>This is an important feature that has been missing from mkgmap for a long time.
  The overview map exists to display a low resolution map of the whole area of a set of
  map tiles.</p>
  <p>Although there has always been an overview map, as it is essential to displaying in
  MapSource or BaseCamp, it has been empty apart from the polygons that show the
  area covered by each tile in the map.</p>
  <p>There was another problem: to compensate for the lack of an overview map most
  map styles, including the default one, contained extra map levels so that the
  map was still visible when zoomed out to the scale of regions and countries.
  This extra data made the map slower when scrolling on GPS devices.</p>
  <p>So the change has a double benefit; the map is still visible when zoomed out far enough to
  show whole countries and continents and can also be faster to scroll on GPS</p>
  <p>The new enhanced overview map will be automatically generated when creating a
  map without having to make any changes. There are however a couple of new options to
  control what happens.</p>
  <dl><dt>--overview-levels</dt>
  <dd>like levels, specifies additional levels that are to be written to the
  overview map. Counting of the levels should continue. Up to 8 additional 
  levels may be specified, but the lowest usable resolution with MapSource 
  seems to be 11. </dd>
  <dt>--remove-ovm-work-files</dt>
  <dd>If overview-levels is used, mkgmap creates one additional file 
  with the prefix ovm_ for each map (*.img) file. 
  These files are used to create the overview map.
  With option --remove-ovm-work-files=true the files are removed 
  after the overview map was created. The default is to keep the files. </dd>
  </dl>

  <h1>Further improvements </h1>
  <p>In addition to the overview map, there is also a slew of improvements and bug fixes
  that have been added.</p>

  <h3>Fixes</h3>
  <p>There are fixes for maps that cover a large portion of the globe or extend to 180 degrees longitude.</p>
  <ul>
  <li>fix wrong interpretation of 0x800000 as -180.0 degrees for maxLon</li>
  <li>fix treatment of very long lines that cross the planet</li>
  </ul>

  <h3>Optimizations</h3>
  <ul>
  <li>The polygon filter allows larger polygons. </li>
  <li>SeaGenerator generates fewer "sea-only" and "land-only" polygons when 
  precomp-sea is used.</li>
  </ul>
  <p>Both reduce the img size, esp. for maps containing large <b>sea only</b> areas. </p>
  <p>An option to better control the minimum size of a polygon that can now be configured per level.</p>
  <dl><dt>--polygon-size-limits=limits-code</dt>
  <dd>Allows you to specify a different min-size-polygon value for each resolution.
  For example: 
  <pre>
    --polygon-size-limits="24:12, 18:10, 16:8, 14:4, 12:2, 11:0"
  </pre>
  <p>
  If a resolution is not given, mkgmap uses the value for the next higher 
  one. For the given sample, resolutions 19 to 24 will use value 12,
  resolution 17 and 18 will use 10, and so on.
  Value 0 means to skip the size filter. 
  Note that in resolution 24 the filter is not used. </dd>
  </dl>

  <h3>Changes regarding styles</h3>
  <ul>
  <li>The support for the obsolete map-features.csv file was removed.</li>
  <li>Level ranges can now use min-max or max-min</li>
  <li>There is now an option <code>--check-styles</code> which will flag issues in the style
  that are known to cause problems.</li>
  </ul>

  <h3>Other changes</h3>
  <ul>
  <li>A few checks are performed regarding the plausibility of the given options and input files
  to help beginners.</li>
  </ul>

  <p>This is just a notice that Java 7 will soon be required
  to run mkgmap. Version 7 was released in 2011 so I expect that
  most people already have it. If not, now is a good time to update
  in preparation. </p>
  <p>Although it was over a year between the announcement that mkgmap would require Java 6 and it actually happening, this time there
  will not be such a gap!</p>

summary:
  <p>Over the last weekend I attended the<a href="http://wiki.openstreetmap.org/wiki/Garmin_Project">
  Garmin Project weekend</a>
  in Essen, Germany.
  It was great to meet and exchange views with 
  all the other participants.</p>
  <p>I am looking forward to seeing the result
  of the main discussion of the weekend
  which was to design a web site to help people without
  any pre-existing knowledge of OSM find maps
  for their Garmin devices in a simple and straightforward way.
  In addition there were many other useful discussions, and the
  chance to meet others face-to-face is very valuable in a project
  such as ours where the only ongoing contact is via email.</p>
  <p>So I would like to thank those that made it all possible, to <a href="http://www.fossgis.de">FOSSGIS</a> who sponsored the event;
  the <a href="http://www.linuxhotel.de">Linux Hotel</a> who support open source by providing
  facilities to events such as this one and to Marc Gehling who in
  addition to organising the whole event, even cooked lunch for us!</p>

summary:
  <p>There is a new feature to help creating rules in the style file
  that help with writing style rules that give a bit more help
  about motorway exits.</p>
  <p>The default style is not affected, this is for style authors to
  use in their styles. It may not work the same on all devices, so
  you should experiment with the results.</p>
  <p>Usually Garmin devices do not display the name of the exit on motorways while
  routing with mkgmap created maps. The new feature allows you to create a
  style rule that names part of the exit link road with the junction number, so
  that when the device tells you to turn onto that road it will include the
  junction number.</p>
  <p>To make this work you have to specify the --process-exits option.
  This works by splitting each motorway_link into three parts. All parts are
  tagged with the original tags of the motorway_link. Additionally the middle
  part is tagged with the following tags:</p>
  <pre>
   mkgmap:exit_hint=true
   mkgmap:exit_hint_ref=ref # tag value of the motorway exit
   mkgmap:exit_hint_name=name # tag value of the motorway exit
   mkgmap:exit_hint_exit_to=exit_to # tag value of the motorway exit
  </pre>
  <p>Adding a rule checking that mkgmap:exit_hint=true makes it possible to use
  Garmin type 0x01 (motorway) for the middle part so that the Garmin device
  displays the name of this middle part as a hint where to leave the motorway. </p>
  <p>An example of such a rule is given below.</p>
  <pre class="wiki-pre">
  highway=motorway_link &amp; mkgmap:exit_hint=true
     { delete display_name;
       name 'Exit ${mkgmap:exit_hint_ref} ${mkgmap:exit_hint_name}' |
            'Exit ${mkgmap:exit_hint_ref} ${mkgmap:exit_hint_exit_to}' |
            'Exit ${mkgmap:exit_hint_exit_to}' |
            'Exit ${mkgmap:exit_hint_name}' |
            'Exit ${mkgmap:exit_hint_ref}' }
      [0x1 road_class=3 road_speed=2 level 1]

  <p>In the past you have used the createboundsfile option to create preprocessed

  <p>The following command chain is an example how to create preprocessed bounds for
  europe. Additionally to mkgmap you need the two tools osmconvert and osmfilter.</p>
  <ol>
  <li>Download the OSM europe extract</li>
  <li>Run osmconvert and osmfilter to extract all boundary information:
  <pre>
     osmconvert europe.osm.pbf --out-o5m >europe.o5m
     # The following should all be one line
     osmfilter europe.o5m --keep-nodes=
       --keep-ways-relations="boundary=administrative =postal_code postal_code="
       --out-o5m > europe-boundaries.o5m
  </pre></li>
  <li>Start the new mkgmap bounds preprocessor:
  <pre>
     # The following should be all one line
     java -cp mkgmap.jar
       uk.me.parabola.mkgmap.reader.osm.boundary.BoundaryPreprocessor
       europe-boundaries.o5m
       europe_bounds
  </pre>This will create a directory called europe_bounds containing the preprocessed bounds which can be used
  with the bounds option on the mkgmap command line. </li>

   SEVERE (RoadNetwork): 63240020.osm.gz: Road (...) contains zero length arc ...
  </pre>
  <p>These were not caused by bad map data, or something that you could do
  anything about. The solution was to give the
  <kbd>--remove-short-arcs</kbd> option. If you did not give that
  option, then you could get routing errors in addition to those error
  messages. This meant that the option was effectively required.</p>
  <p>This has now been fixed and in the latest versions of mkgmap the
  option is no longer required and at some point in the future it will
  be removed altogether.</p>

summary:
  <p>Both splitter and mkgmap now support the <a href="http://wiki.openstreetmap.org/wiki/O5m">o5m</a> format. You can read these files
  just by putting them on the command line as with any other file. For splitter
  the default output format remains pbf, so if you want it to produce o5m files
  on output then you will need to give the <tt>--output=o5m</tt> option.</p>
  <p>Files in the o5m format are larger than those in the pbf format, but are faster
  to read, particularly for splitter when it has to re-read the input file
  several times.</p>
  <p>There is not such a large speed advantage for mkgmap.</p>
  <p>The o5m support was added by Gerd Petermann.</p>

summary:
  <p>Congratulations on a much improved version of splitter that was released
  today by Gerd Petermann.</p>
  <p>The first improvement is that it fixes the annoying failures on large multipolygons
  such as lakes and forests and also on long ways such as ferry routes or country borders.</p>
  <p>The previous method used by splitter could not guarantee that all features that should affect a tile
  but were wholly or partially outside of the tile would be correctly included.
  The new version tracks down all these cases and makes sure that they are complete.</p>
  <p>Currently you have to supply the <code>--keep-complete=true</code> option to get the new
  behaviour, but as the results are so much better this will surely become the
  default soon.
  It does take a little extra time and more memory with this option, but as the resulting file sizes
  are smaller, it takes less time to run mkgmap on them so there is not so much
  difference in the overall time taken.</p>
  <p>The split is also improved to make the tiles sizes more even. This means both a more
  consistent number of points within the same tile and the tiles are more
  square with an maximum aspect ratio of 1:4 if possible with the given input file.
  More care is taken with tiles that approach the poles or the 180 degree of longitude line.</p>
  <p>The <a href="http://wiki.openstreetmap.org/wiki/O5m">o5m</a> format is now supported for both
  read and write. The o5m format is somewhat quicker when used as a splitter input file.</p>
  <p>There are also loads of bug fixes too!
  This is all available in release r263 which
  can be obtained as always from the <a href="/download/splitter.html">splitter download page</a>
  There are many more changes than are mentioned here, so for full details
  read the full description <a href="/pipermail/mkgmap-dev/2012q4/015806.html">[1]</a></p>
  <p>General information on how to use splitter can be found at
  the <a href="/tile-splitter">tile splitter</a> page.</p>

summary:
  <p>Another recent feature added is the ability to compile TYP file from the .txt
  format.</p>
  <p>There is no special option needed, just place the .txt file on the command line wherever you would normally put a .typ file and it will be compiled to a .typ file with the same name and processed as though you had put that file on the command line.</p>
  <p>A TYP file has a family id, and this must match the map it is used with.
  To make this easy, the family id is set automatically by mkgmap to the family-id that is
  being used to compile the map set.
  This will override any family id that is set within the TYP txt file itself.
  If no family-id option is given then the one in the txt file will be used.</p>
  <p>The compiler supports some of the newer features in the TYP file:</p>
  <ul>
  <li>images with single colour transparency (gif-style)</li>
  <li>images with partially transparent colours (alpha channel)</li>
  <li>true colour images (16 million colours)</li>
  <li>true colour images with transparency</li>
  <li>Icons containing the same image in different resolutions, that can be displayed at a high resolution on newer devices.</li>
  </ul>
  <p>The .txt files are best created with a graphical editor such as <a href="http://pinns.co.uk/osm/ostyp.html">TYPWiz</a> or the <a href="http://ati.land.cz/gps/typdecomp/editor.cgi">
  ati land</a> web based editor.</p>
  <p>There is a wiki page that describes the language that is accepted
  at <a href="http://wiki.openstreetmap.org/wiki/Mkgmap/help/typ_compile">mkgmap typ compile</a>
  if you want to write software to create such files or even create them by hand!
  The compiler also attempts to read files produced by all the major know editors
  in addition to the recommended syntax described on that page.</p>

summary:
  <p>The latest versions of mkgmap can now build a street address index when
  creating a gmapsupp.img file for a GPS device.
  This means you do not have to use MapSource to perform this step any more.
  This will be particularly beneficial to those using Linux to build their maps.</p>
  <p>There is no special option to enable this new feature, if you have both the --index and --gmapsupp
  options, then the street index will be built inside the gmapsupp.img that is created.</p>
  <p>The main thing to watch out for is that if you <b>also</b> have the --tdbfile flag set you will get
  <b>both</b> indexes and this will use more memory.
  Best thing is just to omit the --tdbfile option if you are not wanting to install the map on Windows.
  Otherwise you can build the gmapsupp in a separate step. You can combine the .img files without having
  to compile them from the OSM files and so this step is very quick.</p>
  <p>At the moment the index will not fully work if you are combining more than one family id into the output file.</p>

  <li id="wn462_20199">Joseph Eisenberg <a href="https://lists.openstreetmap.org/pipermail/tagging/2019-May/045744.html">drafted</a> a <a href="https://wiki.openstreetmap.org/wiki/Proposed_features/Tag:golf%3Dcartpath">proposal</a> for <code>golf=cartpath</code>, which is intended for paths within golf courses that are designated for golf carts.</li>
  <li id="wn462_20203">Leif Rasmussen incorporated feedback on his <code>connectivity=</code> <a href="https://wiki.openstreetmap.org/wiki/Proposed_features/Connectivity">proposal</a> and <a href="https://lists.openstreetmap.org/pipermail/tagging/2019-May/045780.html">asks</a> for final feedback before he moves to the voting phase.

  <ul>
  <li id="wn462_20185">Tense discussions about iD and the legitimation of the iD maintainers to unilaterally decide mapping questions such as the implementation of new tags without the OSM community resurfaced following the widely, on <a href="https://github.com/openstreetmap/iD/issues/6409">GitHub</a>, OSM&#8217;s <a href="https://lists.openstreetmap.org/pipermail/tagging/2019-May/thread.html#45462">tagging mailing list</a> and the <a href="https://lists.openstreetmap.org/pipermail/talk/2019-May/thread.html#82538">general mailing list</a> disputed decision to implement a validation rule asking to add <code>highway=footway</code> to <code>railway/public_transport=platform</code>.<br />
  The disputes followed shortly after the invention of <code>nosquare=yes</code> to &#8220;resolve all unsquare way issues&#8221; which was also widely challenged on <a href="https://github.com/openstreetmap/iD/issues/6332">GitHub</a> and the <a href="https://lists.openstreetmap.org/pipermail/talk/2019-May/thread.html#82506">general mailing list</a>.<br />
  During the discussion some ideas like an iD fork or potential policies for developers were raised. Unfortunately the discussions escalated and led the iD maintainer Bryan Housel to <a href="https://github.com/openstreetmap/iD/issues/6409#issuecomment-495231649">lock a ticket</a> in GitHub which was seen as rant by others and led <a href="https://www.openstreetmap.org/user/SomeoneElse">SomeoneElse</a> to <a href="https://github.com/openstreetmap/iD/issues/6442">submit</a> a code of conduct complaint about the used comment.<br />
  The discussion spilled over to the mailing list of the OSM Foundation, where Christine Karch <a href="https://lists.openstreetmap.org/pipermail/osmf-talk/2019-May/006068.html">offered</a> a slot at the upcoming SotM on 21–23 September 2019, an offer <a href="https://lists.openstreetmap.org/pipermail/osmf-talk/2019-May/006069.html">declined</a> by iD&#8217;s key maintainer Bryan Housel.</li>

The investigation, which was carried out on the basis of 10 selected companies, found that corporate mapping focuses thematically on roads and raised questions about how OSM should deal with the growth in corporate edits.</li>

With his proposal for <a href="https://wiki.openstreetmap.org/wiki/Proposed_features/crossing%3Dmarked"><code>crossing=marked</code></a> he is disturbing a wasps nest: the tag has already been implemented in iD but the usage is <a href="https://lists.openstreetmap.org/pipermail/tagging/2018-October/040245.html">disputed</a>.</li>

He ignored requests to discuss such a change with the OSM community.

  <li id="wn458_19974">Winner of the 2018 Greatness in Mapping Award, <a href="http://hdyc.neis-one.org/?tshedy">Tshedy</a> (Mats’eliso Thobei), organised a <a href="https://www.openstreetmap.org/user/tshedy/diary/48385">24 hr mapathon of Lesotho</a> on Friday 26th April, to bring the map of the next level. On Twitter she <a href="https://twitter.com/Tshedy4/status/1122046666121650176">thanks</a> all participants for the support and for the encouraging messages.</li>
  <li id="wn458_20008">Colin Blackburn <a href="https://twitter.com/ximenesuk/status/1122568943695269889">reports</a> on his <a href="#wn455_19833">long planned</a> investigation of a &#8220;Clothing Optional&#8221; area mapped in the Netherlands, and finds no on-the-ground evidence for this name tag.</li>
  <li id="wn458_19971">The voting for <a href="https://wiki.openstreetmap.org/wiki/Proposed_features/Landcover_Barren"><code>landcover=barren</code></a>, a tag for areas without vegetation and with bare soil, <a href="https://lists.openstreetmap.org/pipermail/tagging/2019-April/044847.html">started</a> but the voting is not going well at time of writing this. Peter Elderson has probably given the reason in a comment to his vote: <em>&#8220;&#8230; your thinking does not match the mainstream OSM mapper&#8217;s view&#8221;</em></li>
  <li id="wn458_19984">Voting <a href="https://wiki.openstreetmap.org/wiki/Proposed_features/Key:golf_cart">started</a> for the key <code>golf_cart=*</code>, intended to express access restrictions imposed for golf carts and similar small, low-speed electric vehicles.</li>
  <li id="wn458_19981">The distinction between <code>waterway=river</code> and <code>waterway=canal</code> is not as easy as one might think. A discussion about the differences was started by Dave F, who <a href="https://lists.openstreetmap.org/pipermail/tagging/2019-April/044852.html">felt</a> that other mappers incorrectly tag the canalised sections at lock gates along rivers as <code>waterway=canal</code>.</li>
  <li id="wn458_20000">Joseph Eisenberg <a href="https://lists.openstreetmap.org/pipermail/tagging/2019-April/044913.html">has added</a> a section about <a href="https://wiki.openstreetmap.org/wiki/Verifiability#Geometry">non-verifiable geometries</a> such as <code>natural=bay</code>, <code>natural=strait</code>, and <code>place=*</code>. However, not all agree with the changes he made as the post from Tobias Knerr <a href="https://lists.openstreetmap.org/pipermail/tagging/2019-April/044916.html">indicates</a>.</li>
  <li id="wn458_19999">Instead of starting the proposal process, Joseph Eisenberg <a href="https://lists.openstreetmap.org/pipermail/tagging/2019-April/044921.html">skipped</a> this step and created a <a href="https://wiki.openstreetmap.org/wiki/Tag:natural%3Dmountain_range">wiki page</a> for <code>natural=mountain_range</code> as the tag is already used over 600 times by over 80 different mappers.</li>
  <li id="wn458_19980">Joseph Eisenberg <a href="https://lists.openstreetmap.org/pipermail/tagging/2019-April/044886.html">created</a> two new proposal pages, one for <a href="https://wiki.openstreetmap.org/wiki/Proposed_features/Tag:natural%3Dmesa"><code>natural=mesa</code></a> and one for <a href="https://wiki.openstreetmap.org/wiki/Proposed_features/Tag:natural%3Dbutte"><code>natural=butte</code></a>. A <a href="https://en.wikipedia.org/wiki/Mesa">mesa</a> is a geological formation also known as table or tableland, potrero or tepui. A <a href="https://en.wikipedia.org/wiki/Butte">butte</a> is and quite similar but smaller than mesas.</li>
  <li id="wn458_20001">Jan S <a href="https://lists.openstreetmap.org/pipermail/tagging/2019-April/044928.html">brought</a> a stripped-down version of the recently declined proposal for police facilities forward for voting. The new proposal consists only of the <a href="https://wiki.openstreetmap.org/wiki/Proposed_features/tag:Police"><code>police=*</code> tag</a>.</li>
  <li id="wn458_20005">fanfouer created a <a href="https://wiki.openstreetmap.org/wiki/Proposed_features/Traction_substations_extension">proposal</a> to allow a better specification of traction substations, i.e. <code>substation=traction</code> and asks for comments.</li>
  <li id="wn458_19958">Anna and Karen from the Geographical Institute of the University of Heidelberg <a href="https://forum.openstreetmap.org/viewtopic.php?id=66029">will improve</a> <img src="https://blog.openstreetmap.de/wp-uploads/2016/12/de.svg" alt="(de)" /> the mapping of Heidelberg, in particular data on accessibility, entrances to buildings and general infrastructure, to enable visitors of the State of the Map in September 2019 to find their way through the nice town and navigate in the best possible way on the basis of OSM data. It would not be Germany if the very first response after the intention was announced, would not point you to the rules. A wikipage <a href="https://wiki.openstreetmap.org/wiki/Detailmapping_Heidelberg">was created</a> <img src="https://blog.openstreetmap.de/wp-uploads/2016/12/de.svg" alt="(de)" /> to coordinate the mapping efforts.</li>

  The courses were facilitated with the help of members of Chadian community and a Togolese mapper thanks to support from the International <a href="https://www.francophonie.org/Welcome-to-the-International.html">Organisation of La Francophonie</a> (OIF). During the workshop, a several days long mapathon has been organized around <a href="http://resultmaps.neis-one.org/osm-changesets?comment=hotosm-project-5520#11/-19.0560/46.7973">lake Itasy</a> at the request of the decentralized cooperation Région Itasy/Nouvelle Aquitaine.

The work ongoing since June 2018, used a whole host of techniques: participative mapping; drones; training in data collection with local administrators and citizens using phones and tablets; focus groups to analyze maps and identify challenges to meet; and quality analysis tools to evaluate mapping.</li>
  <li id="wn458_19966">The deletion of wiki pages remains unregulated. The proposal for a deletion policy for the OSM wiki <a href="https://wiki.openstreetmap.org/wiki/OpenStreetMap:Deletion_policy">failed</a>. The main point against were the bureaucratic hurdles that would have been implemented by this policy although some, who rejected the proposal, accepted the need for some form of rules. As time passes and the number of outdated pages increases the question might re-appear. In our last issue we reported about a prominent <a href="#wn457_19949">complaint</a> about a deleted wiki page.</li>

  <li id="wn456_19899">The tag <a href="https://wiki.openstreetmap.org/wiki/Tag:place=locality"><code>place=locality</code></a> is currently used about 1.3 million times. The tag is used for a lot of different purposes such as ghost towns and railway junctions in the USA or in <a href="https://taginfo.openstreetmap.org/keys/locality#values">combination</a> with <code>locality=townland</code> and <code>locality=subtownland</code> in Ireland. This led Joseph Eisenberg <a href="https://lists.openstreetmap.org/pipermail/tagging/2019-April/044578.html">to ask</a> whether <code>locality=*</code> could be used to specify the type of locality.</li>

In his post, he explains the details of those voting procedures.
