How to prepare Sentinel-1 images stack for PSI/SBAS in SNAP

as you described, the lat/lon information wasn’t transferred correctly.
I hoped this was not the case for the GUI part.

I have no idea at which step the geocoding went lost, to be honest. If you exported lat/lon bands with at the interferogram step and the StaMPS export didn’t give any warning it should be alright.

Some thoughts:

  • Have you set the processor to ‘gamma’ before starting the matlab processing?
    You can check with getparm, sometimes it is still ‘doris’. I don’t know if this caused the error but it could be worth a try.
  • Have you replaced the matlab script and the shell script provided by catherine here: Workflow between SNAP and StaMPS
    Make sure you have a copy of the old ones and then rename them accordingly so they are addressed under the original name.
