Workflow between SNAP and StaMPS

Dear @bayzidul, @ABraun, @FeiLiu, @annamaria, @katherine…,

I have successfully get PSI result from StaMPS with 70 sentinel-1 images by using SNAP 6.0 PREVIEW4.

Now, I’m trying to process with SNAP 6.0 PREVIEW5 and met some problems.

I found that in PREVIEW5, we couldn’t put the products with Terrain Correction (stack_deb_TC and stack_deb_ifg_dinsar_TC) in stamps export. It would have error like this:

So, I just put “stack_deb” and “stack_deb_ifg_dinsar” for stamps export. After this step, we could directly get master_date.lon and master_date.lat in the geo folder.

And then processed in StaMPS, it took very long time (over one day) in step 6 so far. It didn’t fail, still running now, but I think it’s not a normal condition for just 12 images.

I also have tried to replace the master_date.lon and master_date.lat files generated by stamps export automatically by the method we got these files before. But it failed in StaMPS step7.

Have anyone test to process with SNAP 6.0 PREVIEW5?
