Hello all,
I am a beginner in InSAR and am currently working on my thesis, applying this technology to an area that experienced subsidence some years ago. The area is residential, with buildings and surrounded by water bodies and vegetation. In conventional DInSAR, the coherence was not so good, which is why I chose PSInSAR for the region, since the buildings could act as persistent scatterers. I am using Sentinel-1 images and processing the PS data in StaMPS.
Based on your experience, do you think this is a good approach for subsidence analysis? Additionally, how can I assess the coherence in the StaMPS PSInSAR results? Or are the results already indicative of high coherence?
I appreciate your help in advance.
