I have this problem with my images of the Ross Ice Shelf: enter image description here

This is an image that has been Radar - Radiometric- Calibrate- Amplitude_HH - Gamma0 followed by Speckle Filter.

This is what happens when I add a Geometric - Geolocation - Ellipsoid Correction - Geolocation Grid enter image description here

This is what happens when I add Geometric - Geolocation - Ellipsoid Correction - Average Height Range Doppler

enter image description here

This is what the image looks like on Copernicus preview: enter image description here

Any suggestions? I'm at a loss

  • what output coordinate system did you select? Maybe it is worth comparing different image resampling methods. It looks like there is some NoData value imputed.

  • please select Nearest Neighbor as interpolation method during the Ellipsoid Correction to see if it makes a difference. Also try WGS84 as reference system for a test.

Problem solved: it does not happen in the previous version 6 of the SNAP software. I was using the latest version 7. Fixed by uninstalling new software and installing a the older version.
