[gdal-dev] Problems with transform raster image - try again !

[Travis Kirstine]

Jan,

Something does not look right with the coordinates / bbox of the
source g8746-1_cit.tif file.

Data should be within the DHDN / 3-degree Gauss-Kruger zone 2 bbox
2490547.1867, 5440321.7879, 2609576.6008, 5958700.0208

The gdalinfo indicates that dataset bbox is
-948545665.890,-1049712345.693, -896499098.738,-1021132473.110.

Are you trying to override the internal header values using the tfw?

My guess is that when you run the gdalwarp it tries to transform the
data using the bogus coordinates resulting in a error.

If you know that the coordinates / pixel size is correct in the tfw I
would strip out the header values by creating a new file.

gdal_translate -of GTiff -co PROFILE=BASELINE -co TFW=YES
g8746-1_cit.tif baseline.tif

This command will generate a tiff with no coordinate information
within the tif header along with a new "baseline.tfw" worldfile.  You
then can edit this worldfile using the values you had indicated.  You
then can try warping this file.

Good Luck
