Hi, it is worth noting that GRASS stores geometric features in its own native (topological) format, and mostly will use a Postgres database to just store the associated attributes. However v.external may allow you to access (non-topological) PostGIS simple features directly on-the-fly by passing it through OGR. But I'm not an expert on that. Also GRASS 7 now lets you communicate with external datasets directly from modules; I'm also no expert there either but hopefully someone else can explain it.
maybe in need of an update, but see http://grass.osgeo.org/wiki/PostGIS Also maybe search for some earlier tutorials by Otto? Hamish _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
