I would like to see the coherence estimation carried through snaphu unwrapping to the terrain corrected product in SNAP. The coherence image is a useful supplement to the deformation map in assessing data quality and emphasizing discontinuities in the data (faults in the case of seismic deformation).
The coherence is already estimated in the infgm formation step, and the result being used in unwrapping step, but there’ll be no change on the real coherence values after the unwrapping step.
I would like to see the coherence map, with the deformation map, in the terrain corrected product. Otherwise I terrain correct an earlier product in the interferogram chain, an extra step.
