Doubt in Step 0: Preparation

[yurioliveira-ctec]

Dear friends, I hope this message finds you well.

I am new to using SARvey and have a question. In Step 0, preparation, it is possible to use some interferogram networks, one of them being the "single-reference network." In this case, does SARvey also support the use of the PSI technique?

Dear @yurioliveira-ctec,
Thanks for your interest in SARvey.
SARvey supports various interferogram network types. The "PSI" technique often refers to a single-reference interferogram network and temporal phase unwrapping using a temporal displacement model. SARvey also provides this option. Please choose the "star" interferogram network and temporal unwrapping in the configuration file. But please be aware that this approach is only suitable if you expect a linear temporal displacement behaviour. If you expect non-linear displacement, you might want to consider a small baseline interferogram network instead.
Best, Andreas

Dear @Andreas-Piter,
Thank you for the detailed explanation and for clarifying the options available in SARvey. I will configure the system as indicated to test the "star" interferogram network with temporal unwrapping. Initially, I am exploring the tool, but my first impression is that it looks excellent.

Best regards,
Yuri
