Hello, I am trying to do the Terrain correction with Snap/ Radar/Geometric/Terrain Correction/ Range -Doppler Terrain Correction. I have a Sentinel 1 B with ellipsoid correction. I don’t understand why that error happens and how I can fix it. I appreciate if somebody helps me. [Snap_error]

You have already applied ellipsoid correction so you cannot apply terrain correction. It’s one or the other. Ellipsoid correction is only used when you don’t have a dem (like an ice or ocean scene) otherwise, always use terrain correction.

Snap Error: Source product should not be map projected S1
