After 5 years of mapping, France municipalities administrative boundaries are finally all mapped in OSM !
Yes, it took 5 years to trace them from the cadastre. It took so much time mainly for 2 reasons: - there are 36681 municipalities in France (40% of all Europe municipalities) - only a part of cadastre data are available in vector format, one third was only available as rasters cut in several pieces for each municipalities with few or most of the time no georeferencing at all... Is has been a huge work, done by almost 250 mappers. Paris was the first one created in march 2008 and Contoire is the last one: http://www.openstreetmap.org/relation/3359872 We made a video to show the mapping year after year: http://vimeo.com/80974060 We have started check the quality of that work, and a first step is summarized in a blog post: http://openstreetmap.fr/node/18532 We are planning some media work around this in the next days. A big big thank to the cadastre authority (DGFiP) who made access to the cadastre possible to create OSM data, and a big big thank to all the mappers involved. -- Christian Quest - OpenStreetMap France Un nouveau serveur pour OSM... http://donate.osm.org/server2013/
