* original data show correct header with projection information * data made from gdal show "raw" as DATUM and PROJ using ecwhed utilities: >Datum = RAW >Projection = RAW What I don't understand is that QGIS or GDAL don't find it from the original data. Is it possible that there is some ECW specific projection information as ESRI one? I saw an ecw_cs.wkt file in the gdal data dir. Any idea?
