land slides are mostly non-coherent processes, which means that the scattering characteristics change during this process. This leads to decorrelation of the phase.
You have chances if you have bare soil areas which slowly move (creeping soil movement), but sudden and large movements of vegetation covered areas are very challenging. Please someone correct me if I am wrong or too pessimistic.
I suggest to have a literature review first to check how people approached landslides using SAR data. To me it sounds rather difficult, but maybe there are ways besides the classic PS InSAR approach.
I’m sure that all of the step in snap2stamps and stamps are right.
I cannot find the mistake about that and solution from the forum.
Has anyone ever faced the similar problem?
Dear @mdelgado
My classmate told me run mt_prep_gamma after snap2stamps, and his Stamps version is 4.01.
He could get the right result.
So I also use mt_prep_gamma, but my version is 3.3b1,
Maybe different version could make different result?
the logfile looks alright so far.
But if you use Sentinel-1 data prepared in SNAP it is better to use mt_prep_snap (as provided by the latest StaMPS version 4.1), because it avoids errors at later steps.
I do not see the whitespace between the masterdate and the path to the INSAR folder. Please check.
Additionally, I am not sure, but it seems you are executing the mt_prep_snap in your current folder which is not the folder where stamps is, right? Please check
I completed my 8 steps of stamps processing. I felt some of my interferograms had snow cover and wanted to remove it from the processing. So I used ‘drop_ifg_index’ in the directory where all my patches are stored. I did not use this option for individual patches. Similarly I changed my ‘merge_resample_size’ to 10 in the directory containing all my patches.
Step 4 was successfully done but in step 5 PROCESSING PATCH_2 is the last message I see.
After this, there is no error nor it is moving forward to patch_3.
Following are my questions?
Should I start from step 3 as I have changed my ‘drop_ifg_index’?
In case yes, should I assign this ‘drop_ifg_index’ individually to each patch and then run step 3?
Similarly, if I try changing the ‘weed_standard_dev’. Should I change it for each patch directory or how it should be done?
