GST (Geosciencies in Space and Time) is an extension of PostGreSQL with the same flavour of PostGis but able to load 3D geometries. Developed by the Univesity of Freiberg (germany) for the european project Promine at this moment is a prototype but it's really promising. You can connect 3D geometries stored on Postgre vía SFS from the program GoCad and GoCando (free) as a client. They are developing an OGC service in order to see 3D geometries on an server.

(I wish I could have funding resources for this). The literature seems to be recently advancing on topological models: http://www.inf.bv.tum.de/papers/uploads/paper_0629.pdf http://www.sciencedirect.com/science/article/pii/S1474034609000287 (the later peer-reviewed journal article even mentions PostGIS!) -Mike _______________________________________________ postgis-users mailing list [email protected] http://postgis.refractions.net/mailman/listinfo/postgis-users _______________________________________________ postgis-users mailing list [email protected] http://postgis.refractions.net/mailman/listinfo/postgis-users
