Error in DEM assisted coregistration with XCorr

Dear all,

I have a problem with DEM assisted coregistration with XCorr.

I click ‘Run’ button and there is an error message "Java.lang.NullPonterException’.

Thanks in advance.



I have the same issue with two Sentinel 1 SLC products. I’ve loaded them, applied the orbit files, and then attempted DEM assisted corregistration with cross-correlation but it fails with this Null Pointer Exception.
In my case (many small islands) TOPS coregistration doesn’t seem to do a great job, which is why I’m exploring other options (mentioned in ).


You should follow the tutorial for S-1 InSAR and use backgeocoding. Images with a lot of water in them are tricky.

Any suggestion to solve this tricky problem?
