Hi I have a problem. Following SQL Statement don't work, why? UPDATE HikeRoute SET the_geom = GetFromastext(Transform(SetSRID(force_2d(the_geom), 21781), 4326)); ERROR: new row for relation "hikeroute" violates check constraint "enforce_srid_the_geom1" Who has a solution how I can do this? Thank you. Regards, Thomas -- Thomas Zuberbuehler http://www.zubi.li
