Greetings,
Could someone please recommend how to create a polygon from a set of polygons?
Specifically, a group of states (say, a set of contiguous northeastern United States) and from that form the polygon containing this region
Much thanks, Max Pyziur [email protected] _______________________________________________ postgis-users mailing list [email protected] http://lists.osgeo.org/cgi-bin/mailman/listinfo/postgis-users
