this is a case where the warning is actually useless, sorry for that
basically the writing function is set to launch a warning when NaNs are inputed (it can be indicative of some issues),
however, in this case NaNs are kept by construction at the borders of the image
you can proceed further, there should be no problem
Thank you. That was helpful.
I have proceeded with the MT adaptive filter, created the interferograms and generated the coherence map.
In order to get QPS (using the MT adaptive filter) I am assuming I would select points based on spatial coherence
When plotting the Spatial Coherence I basically get a map of all zero and in fact, no points can be selected (e.g in MISP) using the Spatial Coherence.
Am I missing something?
Unfortunately, after creating the MT adaptive mask, I did process all the interferograms, selecting the “MT adapt” in the presets of the InSAR Params. Left everything else as default, processed the interferograms and created the coherence map with the results described.
