I am trying to perform a crossINSAR workflow between ERS-2 and ENVISAT to exploit the large baseline between the two
images and the 30 minutes acquisition difference in order to create a DEM.
I performed correctly the orbits application, the cross INSAR resampling (I tried ERS to ASAR and viceversa), then the coregistration and everithing run fine.
But when I tried to compute the interferogram then the processing does not go on and I received any error message.
My version of SNAP is the 4.0.
Any idea why I got this error?
