PSInSAR using PySAR

[Andre Theron]

I need to run some kind of persistent scatterer processing and have given up on using Stamps (matlab issues)

Is this software capable ?

Is there another python implementation that would be better?

I am keen to adapt the code for different needs...

Hi Andre,

Sorry for the late response, I just come back from the AGU meeting. Regards to your question, no, the current PySAR is for SBAS algorithms only, which usually have lower spatial resolution than PSInSAR algorithms. Sara Mirzaee in our group in Miami is developing a SqueeSAR-like code in python and will open it in the future. I don't have an exact timeline for it.

Except for StaMPS, I am not aware of other open-source code for PSInSAR. Here is a summary of SAR/InSAR code available in the community:

Hi Yunjun, everyone,

Do you know of any updates in this space?

I see https://github.com/geodesymiami/rsmas_insar/wiki/Big-Ideas speaks about "SqueeSAR for PySAR".

If MintPy has evolved to accommodate PSInSAR it would be helpful to know recommended configuration.

Many thanks.

Hi Russell,

For the SqueeSAR-like algorithm, please check MiaplPy (https://github.com/insarlab/MiaplPy) or FRInGE (https://github.com/isce-framework/fringe). Both of them have implemented the SqueeSAR algorithm, plus the latest development from DLR for more efficient computation. Their output is compatible with MintPy.

Cheers,

Yunjun

Awesome. Thanks. I was not aware of the insarlab repo.
