I'm developing a gis solution which uses only geometry data.
I designed my spatial DB with PostGIS and now I'm performing some trials connecting the DB with GeoServer map server (using the administration page).
In the layer definition of the administration tool there is the mandatory field SRS(Spatial Reference System) to set with the appropriate SRID
I'd like to know which is the default SRID value to set in order to take into account the geometry type. I read that should be 0, but it doesn't work....
