Adding 2D points seems to work fine.
There's no proper 3D topology support, but you do can equip your primitives with a per-vertex Z value (2.5D) if you account for it at topology creation time. See manual page entry for CreateTopology on how to do that. > pgadminIII gives a rather cryptic type of "geometry(1107456)" as the > data type of the "geom" column of the "node" table of my topology. That is annoying, I would expect something like "geometry(point)" or "geometry(pointZ)" instead. Do types of other spatial tables look fine in pgadminIII or is it a general issue with any geometry column ? --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
