I imported those without doing any polygon-overlap-detection stuff. So they will probably overlap quite readily in some places. ___ Talk-ca mailing list Talk-ca@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-ca

Have they been tagged differently, or duplicated? Anyone > have a border-checker script? They weren't duplicated. Ian (I believe?) imported the borders for the New England and Mid-Atlantic states and I imported the rest. Looking at my saved .osm files from the state boundary import,it looks like they are tagged: admin_level = 4 border_type = state boundary = administrative state:left = foo state:right = bar Cheers, Adam > > See it here for part of North East. http://weait.com/maps very slow > server/connection. > > Best regards, > Richard > > > P.S.

Have they been tagged differently, or duplicated? an additional possibility is eastern borders are more wiggly following terrain as opposed to ruler on a map by the surveyors following in the wake of Lewis & Clark , and so those borders might render wider at low zoom, because the points are dense and not aligned? In the bad old days, mapping systems had to decimate borders to scale before rendering, which can alas truncate Cape Cod. -- Bill n1...@arrl.net bill.n1...@gmail.com ___ Talk-ca mailing list Talk-ca@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-ca
