If and when you do this, could you compare to the VCGI data for the NY/VT border at http://www.vcgi.org/dataware/?page=./search_tools/search_action.cfm&query=theme&theme=003&x=17&y=6 (BoundaryOther_BNDHASH layer)? I plan to import VT town boundaries from that file at some point, but was not planning on touching any of the state boundaries (except to connect town boundaries to them). I'd be interested to know how well that data source matches others for the state boundary, too, though. Further information about this file (licensing, etc) on the imports list. --Andrew _______________________________________________ Talk-us mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-us
