I am trying to replicate the RUS Webinar “Land Subsidence mapping with Sentinel-1” on a pair of S-1 images, both images are IW-SLC, same track (but different orbit) and both descending. I am running SNAP 7.0 on Ubuntu 18.04 and I have 35GB free space. I have succesfully applied ‘Apply Orbit file’ and then ‘S-1 Back Geocoding’ but when I try to apply ‘S-1 Enhanced Spectral Diversity’ I get the following error, which is not solved even if I tried to tweak the parameters:
A problem occured during the target product processing
Type: OperatorException
