Hello! I am having an issue when trying to Terrain correct a DEM generated by an interferometric pair of SAOCOM images. This problem does not occur when I work with ALOS images even though I use the same workflow for DEM generation.
Neither of the intermediate products have this problem.
Workflow used:
- Corregistration
- Interferogram formation
- Multilooking (4)
- Goldstein Filter
- Phase Unwrapping with SNAPHU
- Phase to elevation
- Terrain correction (here is the problem)
I work with SNAP 8 in Windows 10 and Linux (Ubuntu 20.04) only for the phase unwrapping.
Below I lay the logfile message extract:

The same happens when I execute it from the GPF command line.
I also tried creating a subset but received the following error:
Thank you for reading. Any comments would be helpful!
