Johannes,
access to your DIMAP product would be needed to investigate.
I assume the product also returns RPC? If so, test GetMetadata("RPC")
!= null, and if it does, you can likely consider than any GeoTransform
is "garbage". If you have RPCs, you can directly compute a geotransform.
You need to reproject using GDALWarp() with the "-rpc" option.

Hello,
coming back to an old thread regarding a DIMAP product which has no
lon/lat
(https://lists.osgeo.org/pipermail/gdal-dev/2018-January/048014.html).
GDALGetGeoTransform method will return CE_None despite
GeoTransformation matrix is not as expected, and in that specific case
I would rather use GDALGCPsToGeoTransform to compute GeoTransform array.
Is there a way I can detect GDALGetGeoTransform shall not be used ?
Thanks,
Johannes
