Hi profijona; my apologies for the slow reply, had urgent project work keep me away from my InSAR processing.
I’ve attempted changing the number of rows and columns and overlap as suggested in your other post here: Snaphu Unwrapping Process Problem - SNAP 12 - #4 by profjona but I keep receiving the same message, overlap is too small which I don’t understand how that can be when setting the overlap to 300 with such small numbers of rows and columns. In previous processing I’ve always done 20 x 20 with 0 overlap and have never had this issue before.
