I'm struggling to create a geometry field in PostGIS that stores Z and M coordinates. Are these supported? Some issues: 1. I cannot create a ZM field. "Dimensionality must be 3 or less" 2. GeomFromText() doesn't recognize "POINT Z (0 0 0)" 3. GeomFromText() does parse (with a warning) "POINTM (0 0 0)", but it appears the DB isn't really storing the Z coordinate. 4. Using the C library interface, I can't get WKB geometry with Z to parse.
Thanks, Ben _______________________________________________ postgis-users mailing list [email protected] http://postgis.refractions.net/mailman/listinfo/postgis-users
