In the 1800s, when they were physically marking the boundaries of Wyoming, they weren't perfectly accurate ("up to half a mile off", as Matthias quotes from Wikipedia). The actual legal boundary of Wyoming is how it was physically marked. "The legal boundary is the surveyed boundary." ( http://proceedings.esri.com/library/userconf/proc04/docs/pap1718.pdf) I assume OSM has the (approximate) legal boundary. I see the OSM state boundary and OSM county boundary diverge a bit, though, and I'm not sure which is more accurate (I assume the legal boundaries coincide). _______________________________________________ josm-dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/josm-dev
