First of all, thanks for sharing this post about staMPS PIS. It seems you helped many people to perform PSI technique.
I have a question.
As we know, in order to properly do InSAR, DiINSAR nad PSI techniques there are some strict rules for deriving optimum results. Two of these rules are the following:
-Satellite orbital path must be the same for both satellites
-Orbit direction must be the same (both ascending or descending orbits)
We may have 15 Sentinel-1A/B images on the archive for one month but only 2 or 3 of them have the same orbital path and orbit direction. In case we need to collect 30 (roughly) S1 images during a 6 month period to perform PSI, we cannot stick to the rules as it is impossible to find so many S1 images with the same orbital path and same orbit direction. So, we might need to use both ascending and descending orbit, or S1 image acquired from different orbits. If we do something like, do you think that this is going to affect a lot our results?
According to your post, how many S1 images did you use? were they all acquired in the same orbital path and direction?
