during the last year I have, as usual, corrected in OSM several small mistakes concening the borders between Belgian municipalities, which are used as level 3 administartive units (counties) in PGC. Would you be kind enough to update the Belgian polygons, please, whenever you have the occasion? (No urgency)
Maybe you could, instead of using OSM, download them from here: http://www.ngi.be/FR/FR1-5-2.shtm
. It’s the official Belgian National Geographical Institute, which offers a free download of the official vectors, so this would solve the problem once and for all (as long as administrative boundaries don’t change, obviously).
Thanks a lot and happy caching,
