Hi, This function assumes that the road network is already segmented. If I have otherwise topologically good network, but without properly segmented streets (e.g. like in OSM Shapefiles), then it does not work.
Best solution would be to have similar extended postgis or pgrouting function to do it. Or is there any other good (and free) tool to do it? /Jaak Re: [postgis-users] Road Network Graph creation Daniel Kastl Sun, 28 Jun 2009 17:17:33 -0700 You need to look for the assign_vertex_id function of pgRouting. This function creates a network topology. Daniel Ben Madin schrieb: Short Answer - Yes - but of course it depends on the quality of your shapefile as to how useful it is.
