Real 3D is not currently supported by PostGIS Topology. I don't understand your statement about creating unneeded nodes though, do you mean multiple nodes with same x,y but different z are created ? Check out topology/test/regress/topo2.5d.sql if you want to add your case there and provide a complete scenario. --strk; _______________________________________________ postgis-users mailing list postgis-users@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/postgis-users
