Hi, I am working on GMTSAR. I have a query about SBAS outputs. SBAS gives two types of output displacement maps in GRD format and velocity.grd. The SBAS command calls the number of scenes and the number of interferograms. But in the output has been created the number of displacement maps same as number of number of scenes. Here I want to clarify (1) Is the velocity map is average of all interferograms? (2) What is the master image of each displacement that has the same date as the scene (is it the super master image or the first scene)?
