How to prepare Sentinel-1 images stack for PSI/SBAS in SNAP

Hi all,

@saidbenchelha
For the mt_prep you should just follow the StaMPS manual.
For me it works the modified mt_prep_gamma_snap for which you should get amplitude average per scene higher than 0.xxxx in my cases between 50 - 80.

mt_prep_gamma_snap usage is indicated while running it without parameters, more or less as follows:
mt_prep_gamma_snap <INSAR_path> amp_disp_thr patch_x patch_y

being INSAR_path the folder which contains the rslc, diff0 and geo folder after exporting the snap interferograms into StaMPS format for PSI using SNAP.

@ledotimea
on the thread: Snap2stamps package: a free tool to automate the SNAP-StaMPS Workflow you can get a new package which includes the ESD in the xml graphs to run using SNAP. This new package uses python and snap, so it should work in Windows, Linux and Mac.

@twburns
For the ps_plot issues that you mentioned… please check as I have not any problems. ps_plot(‘v’), ps_plot(‘v-d’,1,‘ts’), ps_plot(‘v-d’,-1), ps_plot(‘d’) worked fine for me. Only when the ps obtained are very high, I got memory issues with Matlab.

I hope this helps.
