Otto, put the new SRS definition into a text file, let's say srs.wkt, and use gdal_edit.py -a_srs srs.wkt But... in your case AUTHORITY["EPSG","9001"] qualifies the UNIT meter and not the whole PROJCS (look at the brackets ;-))), which is what you likely want to do. So you could more simply use -a_srs EPSG:XXXX where XXXX is the EPSG code of the CRS (25833 might be a good candidate in your case) Even -- Spatialys - Geospatial professional services http://www.spatialys.com _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
