License change of OpenStreetMap data and its effects on wikipedia
by Kai Krueger 11 Jul '12

11 Jul '12

Hello everyone, as many of you will already know, OpenStreetMap has been planning to change its license from CC-BY-SA 2.0 to OdBL 1.0 for a long time now (several years). It appears that the date of the actual change is now approaching fast and that the intended plan[3] suggests that the change will begin on the 27th of March and be complete by the 1st of April. As, unlike Wikipedia, with its change to CC-BY-SA, OSM so far has not had a clause in the license to switch to a different license, it had to independently and separately ask all of its contributors to relicense their data to the new license. In a project with more than 200.000 contributors reaching all of them and getting them to agree to a new license is an (near) impossible task. Therefore despite OSM(F)'s best effort to reach as many mappers as possible, obviously not all could be reached and convinced to agree. As OSMF does not hold the copyright (the individual mappers do), it can only re-license the content for which it has permission and has to delete all other data. Worldwide currently 2% - 3% of data are affected[1], but for some regions or countries 10% or more of data have to be deleted. The question for Wikipedia (in the sense of the maps rendered on the toolserver and embedded in a number of language wikipedia's) now is how to handle the license transition? My suggestion is to freeze the toolserver's openstreetmap database on the 27th and stop all data updates for now. After the dust settles on the license change and the impact of the deleted data become more apparent, one can reevaluate the situation and decide at what point the missing updates are worth more than the deleted data. At that point a fresh import of the OSM database would be necessary after which the updates can resume. My guess would be that it would take a few weeks or perhaps month for the most visible damage to the data to be fixed, but it is very hard to predict this so far. An overview of the current situation can be seen on cleanmap [2], which shows either what the map will look like after the license change, or on badmap which data needs to be removed or modified before the license change. After the re-import, it will also require a slight adaptation of the attribution to reflect the license change to OdBL. The tiles (which are embedded in Wikipedia) I believe can still be published under CC-BY-SA (it is only the data that is under OdBL, not the produced work) and I don't think it will directly impact (or prevent) any of the current other usage of OpenStreetMap data in Wikipedia. However, I don't know if the Wikimedia legal council has or wants to say anything about it and / or give its OK for continued inclusion? What do others think? How should the OSM license change and the resulting removal of data from its database be handled in Wikipedia? Do people agree with the above suggestion? Does it have any other consequences? Further thoughts?

Announcement: WIWOSM project
by Tim Alder 23 Mar '12

23 Mar '12

Hello, next week I want to publish the next big step for the cooperation between OSM and Wikipedia: http://wiki.openstreetmap.org/wiki/WIWOSM This project will add an vectorlayer to the OSM-map in Wikipedia. The content comes from OSM for objects with key=Wikipedia. I believe it's a big step because it will give the wikipedia user really more information to an object, it will change the working of wikipedias geocoding and can perhaps substitude on some points the work of Wikipedia's map-workshop. On the other side it will be also a lot work over the next months and years to create and maintain all the Wikipedia-Tags in OSM to connect both projects. I create this project together with User:master. As first step a plan to introduce it in german Wikipedia to get direct feedback from there. If everything is fine (and after license-change of OSM at first April) I will rollout to all other languages. Feedback and tests are very welcome. ----- BTW: What stops us? I check the new script (see project page) in IE6 and IE7 and it works fine, off course also under konqueror, safari, FF and chrome. But in IE8 it works on one computer and on the other not. (The error message is at the end of the mail.) So if you have a chance to check the script under IE it would be nice to give me a feedback. If you find the bug in line 1403 of OpenLayers.js it would be wonderful if you can help me to fix it.

osm2pgsql waterway relations WIWOSM
by Tim Alder 22 Mar '12

22 Mar '12

Hello, I got from WIWOSM a bug report, that the relation of river danube is missing. This relation has the type waterway. The reason is that we have the relation not in toolserver-db: http://www.openstreetmap.org/browse/relation/89652 We have also a lot of articles like: http://en.wikipedia.org/wiki/U2_%28Berlin_U-Bahn%29 Would be nice to support also this. My question is now if we can change the config of osm2pgsql for the next import (after license-change) to support this ? Will this effect the rendering? Do we need a second database? I would also like to know why Austria is working in WIWOSM but not for Germany. Greetings Tim

Old maps
by Lars Aronsson 21 Mar '12

21 Mar '12

I just learned that two very nice sets of old, out-of-copyright Swedish maps have been made freely available. Maybe they have already been around for a while, but I just learned this now. One set is the topographic map (popularly called Generalstabskartan) in scale 1:100,000 for southern and 1:200,000 for northern Sweden. The other is the economic map (Häradskartor) in more detail. These maps have long ago been digitized by the Swedish ordnance survey (Lantmäteriet), but they don't allow downloading and reuse. Now, however, they have been (digitized again? and) made freely available by Stockholm University library, http://kartavdelningen.sub.su.se/kartrummet/kartskapet.htm The maps are scanned in 600 dpi and are available in TIFF and JPEG. Some have also been geo referenced and have TFW and KML files for download. Can we somehow get these huge bitmap images into a tileserver? They need of course be stretched to fit the coordinates, and the borders and overlaps need to be aligned. What tools are available for that? Would WMF support and host this? Would OSM? If someone can do this for a fee, maybe the Swedish chapter can find the money. -- Lars Aronsson (lars(a)aronsson.se) Aronsson Datateknik - http://aronsson.se

How to tag? was: Announcement: WIWOSM project
by Daniel Schwen 16 Mar '12

16 Mar '12

Hey Tim, can you point us to a tutorial or manual on how to add these tags to OSM? I tried unsuccessfully to add the tags to a US county. With the editors I have (potlatch2, merkaartor) I con only download a tiny portion of the map. I can select part of (what I think is) a county line (but it has no keys indicating that it is a county line, odd!). Is it sufficient to add the Wikipedia tag to such a part of a county line? Does that tag a closed polygon, or just the small line segment? Sorry, I'm not exactly an OSM editing pro, but willing to learn to help with the tagging effort.
