The first argument to getRingEdges is a topology _name_. You're passing "edge_data", which is the name of a table. You should pass 'TEST' instead. The second argument is an edge identifier. You're always passing '1'. You probably want to pass edge_id instead. But again, you didn't answer the most important question, being: what are you looking for, exactly ? --strk; ,------o-. | __/ | Delivering high quality PostGIS 2.0 ! | / 2.0 | http://strk.keybit.net - http://vizzuality.com `-o------' _______________________________________________ postgis-users mailing list postgis-users@postgis.refractions.net http://postgis.refractions.net/mailman/listinfo/postgis-users
