When asked for a version please report the output of: SELECT postgis_full_version(); That way we have full information. There is 2.0.0 and 2.0.1 of PostGIS. > I tried in two ways.. > FIRST, I populated geometry to the schema using CreateTopoGeo, and then Great, it looks like it worked. > updated > the topology column using CreateTopoGeom... (the query and data attached) I fail to understand your CreateTopoGeom query in there. Did you try toTopoGeom as a replacement of CreateTopoGeo and CreateTopoGeom ? > but when i visualized the result of topology in x3d, it was mess..maybe i > made a mistake by wrong query?? How did you visualize ? What do you mean by "messy" ? The topology in your backup results valid, and I can see it just fine. But yes, I do see a lot of very small faces, a lot of edges close to one other. Maybe you should try to specify a tolerance when creating the topology. Did you try that ? > SECOND, i tried to update the topology column using toTopoGeom..but > this not succeeded..the query and the message error as below > > UPDATE simpanglima.ruang > SET ruang_topo = topology.toTopoGeom(ruang_geom,'simpanglima_topo',3) > WHERE rid='1'; > > ERROR: function topogeo_addpolygon(unknown, geometry, numeric) does not > exist > LINE 1: ...yer_id, element_type, element_id) SELECT 5, 3, 3, topogeo_ad... Sounds like a bug which got fixed in 2.0.1. You can work around it by adding "topology" to your search path. search_path search_path to <output_from_previous_query>, topology --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
