Hi regina, well i can update. but i would like to avoid if i could, because our the company that maintains our postgis production servers wants to see some money for doing the update. but probably we are going to do that anyway, because it will be the easiest step to get my production doing the same like my testing.
thanks and best regards, stefan > -----Ursprüngliche Nachricht----- > Von: "Obe, Regina" <[EMAIL PROTECTED]> > Gesendet: 18.09.08 15:23:09 > An: "PostGIS Users Discussion" <[email protected]> > Betreff: RE: [postgis-users] problems with transformation > Not that I know of, but Frank would have a better idea.
