SBAS-DInSAR processing on the ESA Geohazard Exploitation Platform

Dear all colleagues,

I’d like to draw your attention to take a look at this lecture


I mentioned that in case of some colleagues need to take a look at that,

My best wishes,


Thanks very much for the information falahfakhri!!!

You are welcome, also please take a look if you like to these following two parts I gave while I have been in the University of Turku- Finland two years ago

Sure, I will to look this!!!.. Thanks falahfakhri

@falahfakhri Thank you very very much for the lecture.
I am trying to understand the SBAS workflow. I can’t undrestand at which stage exactly the SBAS baseline graph of the InSAR pairs can be created? I found in some materials that the basline graph is done based on the delaunay triangulation but I am not sure if it is done at the first step of the pairs selection or at the phase unwrapping stage?

Actually you’re talking into two different things, the unwrapping algorithm should be done in whatever InSAR technique to get the real distance between the target and satellite in other words to to convert

g1 = a1exp(i4πR1/λ)

Please have a look at the following link,
