I guess there are no rows in union_cty_topo.summit_fa ? Beside, are you trying to create a TopoGeometry formed by _all_ faces in the "face" table ? Note that such thing would include the universe face, which doesn't make much sense. Anyway, PostGIS should just give you a TopoGeometry representing the union of all faces in that case. Thanks for spacing, btw. If you can space also vertically I'll love it :) --strk; ,------o-. | __/ | Thank you for PostGIS-2.0 Topology ! | / 2.0 | http://www.pledgebank.com/postgistopology `-o------' _______________________________________________ postgis-users mailing list postgis-users@postgis.refractions.net http://postgis.refractions.net/mailman/listinfo/postgis-users
