Wow. Hard to argue with that! It does look great. > Attributes are also an improvement for geocoding, routing, and naming. True. We do have addresses in the TIGER data, but I chose not to upload them for now. OSM didn't have relations when I was doing the original TIGER upload, and I'm still not sure there is any consensus on how to do address data.

My suggestion would be to get a planet file, and try to extract the areas that you care about. http://wiki.openstreetmap.org/index.php/Planet.osm You could just about download the entire thing in JOSM, too. It's a pretty dinky^Wmodestly sized state. ;) Once you have a copy of the existing .osm data, just grep through the XML to look for authors, or look at the authors panel in JOSM. -- Dave _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk-us
