[gdal-dev] GDALwarp - Too many points (441 out of 441)

[Tobias Heuchel]

Thomas,

you coord. values do have the zone digits (in your case 33) in front of the east values. This is a way in Germany (or also other countries?) to use the coordinates sometimes, but as far as I know definitely not the default in using UTM coordinates and sometimes confusing. To get the things work, take a UTM zone 33 coordinate sytem definition and change the false easting  by applying an additional 33000000 meter shift and you probably can work with these coords. Or just for testing remove the first 2 digits (33) on your coord. east values.
