SBAS-InSar processing in SNAP

thanks for your help

Hi,
@ABraun @thho

Can I know if SBAS interferograms can be generated using SNAP 8.0?
If not please kindly let me know which software can be used for generating SBAS interferograms to work with StaMPS as I plan on combining both PSI and SBAS using StaMPS for my thesis. Please kindly help me with this.

Please see this topic: Please test the SBAS_snap2stamps

Hi, did you manage to preprocess data for SBAS StaMPS? Thanks.

Hi,
No, I migrated to GMTSAR for performing SBAS.

Hi

I am wondering if anyone has been able to use SNAP to create SBAS network of interferogram? I am planning to use PyRate. Has anyone tried the PyRate export feature of SNAP? Even without that, exporting each interferogram as Gamma format should work, right?

As mentioned in the post, if SNAP does not yet support automatic generation of SBAS network of interferogram I will do it manually. Do you have any guideline on how to set the criteria for the baseline (perpendicular and temporal).

If anyone has some tips on how to use PyRate it would be welcome as there are not that many tutorial for the momentā€¦ Especially on how to prepare the inputs.

Thanks

What kind of problems commonly encountered in SBAS approach that is based on the retrieval of time series cumulative deformation using the least squares method? Shaowei Li et. al 2022 have mentioned rank deficit problems but I didnā€™t properly understand what they meant. If you could elaborate or provide a text that has a simplified explanation of SBAS? I couldnā€™t find anything relavent to in in Hanssen 2001 maybe because it was developed later.
