TerraSAR-X images and Range Doppler Terrain Correction, I get this error message:
What’s wrong?
Possibly the input product type.
which product level did you order? SLC, MGD, EEC, GEC?

Product level is GEC.
that means there is already a projection in the data, so Range Doppler Terrain Correction can not be applied.
Do you have the chance to get the data in SLC format?
