It supports 2.5D topology (a Z value for each vertex, but no volumes). You need to specify you want Z at CreateTopology time. For populating it you can use the TopoGeom_add* family of functions. See the PostGIS manual for details. http://www.postgis.org/documentation/manual-2.0/ --strk; http://www.cartodb.com - Map, analyze and build applications with your data ~~ http://strk.keybit.net _______________________________________________ postgis-users mailing list postgis-users@postgis.refractions.net http://postgis.refractions.net/mailman/listinfo/postgis-users
