Giovanni, I'm afraid I don't really follow your point. Are you wanting to be able to do something like -t_srs GFOSSIT:3033 ? Note that you can register coordinate systems with spatialreference.org and then use those urls with GDAL/OGR tools if you want something customized. Keep in mind that some OGC web services are not going to support such mechanisms in an interoperable way. > In the meanwhile I will ask the GFOSS.it community to consider the > opportunity to add a datum_shift_pref.csv row. > > The idea of a DATUMSHIT selector would be nice ;) I'm not too sure if your misspelling is intentional or not, though it captures how I often feel about datums.
