Actually, I will analysis slow-move landslide with PSInSAR method.
I found some interference information of settlements in mountain areas by DInSAR with sentinel images. So, I want to check the move motion by interferograms in different time. I’m not sure will it work or not, because we couldn’t get good interferogram in mountain areas with other C-band data. In addition to that, I also tried to process the co-seismic surface deformation and land subsidence by DInSAR method.
Could you tell me how to check the topographic phase removed correctly or not? If there exist some problem in this step, how to solve it?
I have followed the steps in “Sentinel-1 TOPSAR Interferometry” tutorial from ESA website. And I have tried many times with different SAR images and parameters, but I couldn’t find the key to solve this error …
I tried snaphu phase unwrapping in ubuntu linux 14.04 LTS. My system is having 8 gb ram (dual boot). I got an error.
When i run the command - snaphu -f snaphu.conf Phase_ifg_HH_23Dec2009_26Dec2010.snaphu.img 4672 it gives an error saying-
snaphu v1.4.2 27 parameters input from file snaphu.conf (84 lines total) only one tile–disregarding multiprocessor option Logging run-time parameters to file snaphu.log>
## Segmentation fault (core dumped)
Please guide me through this.I am not using cygwin terminal.
I am trying to use snaphu to unwrap my data, too. but the following appears after running
Unwrapping tile at row 4, column 7 (pid 2977)

PL help me
hi, i,ve been finished the process, as you can see from the picture, i got the color dimension in abs_phase, but i saw from the other posted some people got into length dimension unit (meter). so how can i get that unit dimension. moreover, does anyone here have information how to analysis for subsidence suppose.
