I have been teaching myself to create displacement products with Sentinel 1, SNAP and Snaphu. I am at the point where I can reliably create a displacement product but I fear I lack some of the more subtle understanding of the parameters when I run my graphs, which I have attached here.
I have been reading many of the links users such as ABraun have shared and I appreciate all the effort that they take in trying to help us beginners.
As a learning exercise I have been trying to measure displacement over time at a dam. Currently, Persistent Scattering methods and Stamps is beyond my abilities, so I have been making several displacement products, adding a coherence band, and masking the displacement by a minimum coherence of .45 or greater. As I understand it, atmospheric effects cannot be controlled for so I have been measuring dam displacement as a value relative to a baseline area near the dam. Is this the proper way to proceed in this case?
Second question is I have been processing my images as follows for time series: A-B, B-C, C-D, D-E, etc.
Should I instead process them A-B, A-C, A-D, A-E, etc? The dam has seasonal subsidence and uplift from what I can tell, but I want to make sure I am doing this correctly so far.
Thanks for any advice!
