[Qgis-developer] OGRSpatialReference problem in QGIS

[Florian Hillen]

Hi Frank,

everythings OK with the path and the wkt now:

PROJCS["unnamed",GEOGCS["DHDN",DATUM["Deutsches_Hauptdreiecksnetz",SPHEROID["Bessel
1841",6377397.155,299.1528128,AUTHORITY["EPSG","7004"]],TOWGS84[606,23,413,0,0,0,0],AUTHORITY["EPSG","6314"]],PRIMEM["Greenwich",0,AUTHORITY["EPSG","8901"]],UNIT["degree",0.01745329251994328,AUTHORITY["EPSG","9122"]],AUTHORITY["EPSG","4314"]],PROJECTION["Transverse_Mercator"],PARAMETER["latitude_of_origin",0],PARAMETER["central_meridian",9],PARAMETER["scale_factor",1],PARAMETER["false_easting",3500000],PARAMETER["false_northing",0],UNIT["Meter",1]]

But the file rasterfile hasn't got the correct settings after the warp, so
I have to check my code again.

Thanks again for the help.

Best regards,
Florian
