Changes in the header don't require a write license So gdal_edit.py -a_srs EPSG:xxxx your.ecw should work and modify in place the ECW Otherwise you can add the -ro flag to the above, and it will generate a .ecw.aux.xml file with the overriden projection info. > Is there an option to add an aux/prj file next to it so that GDAL will read > the correct CRS from the aux file instead of from the ECW file ( i.e. from > GeoServer/QGIS) ? > I know I can workaround it with a VRT file but I think it might degrade the > performance. For "simple VRT" generated with "gdal_translate your.ecw your.vrt -a_srs EPSG:xxxx -of VRT", the VRT driver has optimizations to directly forward pixel requests to the underlying driver with minimal overhead.
