Today, I added a non-mapped quarter of Aix-En-Provence into the OSM datas. I think I have forgotten a few things, so I will probably return there a next time. I noticed by comparing google's map that there were a few errors on "official and proprietary" datas by the way.

About Aix, a mapper is willing to organize a mapping-party for the end of this month. Who wants to attend it around here ? Of course I'll be in, but for the moment we are only 2 :-)
