I’m interested to do the process of land subsidence and displacement analysis using SENTINEL 1 data.which type of data( like which modes,polarization,sensing mode) can be use to execute the process and how the process can be do for the analysis
To convert it to absolute phase changes, the interferogram must be unwrapped.
Unwrapping itself is demonstrated here: SNAPHU Unwrapping
Then you import the unwrapped phase back into SNAP (described here: Problem in Snaphu Import section)
Lastly, you perform “phase to displacement” to get the change along the line of sight.
Thank you for the comprehensive reply. I have greatly benefited from it.
But I need to take some steps further, which I am not very clear with at the moment. I want to monitor subsidence for over a period of 4 years. Please, what further steps can I take to achieve this goal.
