Well, the dispersion comes from the APS of the slaves.
I have compared SNAP derived interferograms with StaMPS and other software and results were similar. With Sentinel-1 the issue comes on the APS, which should be taken carefully into account.
The Netherlands is also really flat, but atmosphere believe me affects the results.
That means, atmosphere only can be neglected if the area covers few Km2 (1km x 1km or 2km x 2km) or big deformation is expected (Earthquake events, or huge subsidence expected)
From my personal experience atmosphere matters, mainly when deformation to measure is small. If you measure deformation in the Mexico city center, atmosphere effects can be neglected.
I am a freshman at SNAP&StaMPS. I have learned a lot from here, thank you all.
I successfully ran mt_prep_snap by cygwin64 (using a modified version provided by someone else on the web). But after running mt_prep_snap, the matlab automatically jumped out, said ""Warning: Name is nonexistent or not a directory: \StaMPS-4.1-beta\matlab:
I had this once because I mixed up a step in the preparation. As I properly did all steps again (only use one polarization to go sure), it worked. I don’t know where it came from but if you stick to the presented order, it shouldn’t happen.
If you have both master-slave amplitude stack and the master-slave interferogram with the elevation mask and the orthorectified latitude and longitude bands in the output, then yes, you can. Otherwise you are not compliant with the input requirements for the StaMPS export operator.
Hello, thank you for your suggestion.
I found a solution of this problem. https://groups.google.com/forum/m/#!topic/mainsar/MDMV9yXDl1g
But it’s too simple, I can’t understand how to execute. I have done creat a startup.m and addpath, but I don’t know how to correct “the call of matlab scrip” or my patch01 data path?
Thank you very much
