I don't know about the rest of the country, but for Pennsylvania (and neighboring New Jersey, which I'm more familiar with), this seems correct. (In Pennsylvania), townships, boroughs, and cities are all at the same administrative level. Of course, in terms of mapping, they probably shouldn't be treated the same, which means the renderer, at least in those two states, should probably ignore admin level > 6. As far as administrative level, it's actually easier in Pennsylvania and New Jersey than it is in say Florida, where some places are governed at level 6 (e.g. unincorporated Hillsborough County), and others are governed at level 8 (the city of Tampa, which is within Hillsborough County). In New Jersey, everywhere is incorporated. I believe it is the same in Pennsylvania, based on the maps and my reading. But I believe most of the US is more like Florida, in that some places are incorporated, and some places aren't. So if you have a place at administrative level 8, it means you have a city. > but they also seem mostly tagged as place=town - which doesn't seem right > > Does this mean I need to go on a campaign and write proposal for adding > place=township? Probably not. I thought place=* tags were based on population. That's what the wiki says. You gotta remember that pretty much every tag key in OSM has to be treated as though it's written in foreign language if you're in a backwards place like the United States. So everything outside of the townships would be mapped from Pennsylvania designations into OSM ones based on population: *First and second class cities -> city **that would be Philadelphia, Pittsburgh, and Scranton *Third class cities -> town *Borough -> village (larger boroughs) or hamlet (smaller boroughs) Which leaves the question of whether or not to map townships as places at all. Looking at the map, townships seem to be what's left over when you subtract out the cities and boroughs, so that would lead me to say no. But if someone more familiar with Pennsylvania can argue otherwise, s/he'd probably be right. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
