Thanks Frank, That was actually my understanding. BSB and Ozi have their GCPs in long/lat, so I thought that a feature for such a case. So, if you have GCP SRS, you don't need SRS set at the dataset level, do you? BTW I've noticed if a dataset doesn't have a geotransform, then ds.GetGeoTransform() returns (0.0, 1.0, 0.0, 0.0, 0.0, 1.0). Is that a feature or a bug? _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
