SBAS connection graph

[m.sedighi]

Dear software developers,

I have seen in SNAP V5 that we can export SBAS/PSI to Stamps software that is a very good idea.
But there is a leakage in this idea which is how we provide interferograms and by which criteria we select the pairs for building interferogams.
I think if you provide a tools for providing connection graph according the interested parameters and if we can use this connection graph for processing the image pairs … it would be useful.

Best regards
Morteza

we discussed the proceeding in another topic:

Workflow between SNAP and StaMPS

Dear Luis, I appologise - I do not want to push you somehow as I really understand how hard your work is! I would like just to have some information to make plans. Is there any success in creating a workflow between SNAP and StaMPS which you mentioned before ? Can we hope to have it in the nearest future? Thank you for all your help Katherine

Here you will find answers on what exactly is needed for the export module. If you have questions it would be better to ask there because some users with experience read and contribute in this topic.

Some more information is provided in the SNAP help:

Please note that currently, only persistent scatterer interferometry is supported and the small baseline approach is not yet included.

Dear software developers,

I;m currently working on SBAS processing to create land subsidence map. Can you show me the SBAS graph on SNAP v6, please? It would be very helpful.

Thank you

Hi @an_nisa3

Would you please to take a look at the last manual version of StaMPS, below you could find a link, SBAS technique is detailed explained,

Also a very nice instruction has been done by our colleague in here,

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

Hello, in the last weeks I tried using the SNAP-StaMPS workflow for PS analysis. I found this thread which was incredible helpful. I summarized…again…the workflow, I found the summaries and hints given were great @katherine, @bayzidul, @FeiLiu, @ABraun. But latest updates of SNAP and the amount of steps are confusing, gathering and following all hints given to reach the goal. Maybe some of you which have experience in the workflow might have a look at the summary to help improving it. Further…

[ABraun]

SBAS is implemented in StaMPS but the preparation of multi-pair interferograms in SNAP is still a challenge and there is no ready workflow yet. But some ideas were discussed here: Coregistrating more than two Sentinel-1 SLC IW products

I really appreciate it. Thank you

Any idea in case the new upcoming SNAP release (I read something, it’ll be released in next May!), does it support SBAS?

SNAP 7 will not support it but support will probably come next year.

Thanks for the information.
