Following RUS Demo: Land Subsidence Mapping using Sentinel-1 webinar to map subsidence of area in British Columbia, Canada, contained in subswath IW2, bursts 6 and 7. Now at the step of SNAPHU phase unwrapping but getting the attached error message when running snaphu.exe: NaN or infinity found in correlation data. Tried removing unacceptable values from the coherence data using SNAP Band Maths but this didn’t solve the problem. Please advise.
