In the way to substract the background radiometry of Sentinel 1 GRD product (varation between sub swath and related to incidence angle), in test I have succesfully remove this background.
But now, I would like to batch the different process and to do that I would like read incidence angle for every pixel.
Best way for me to use it in python would be create a new file containing the incidence angle in the same geometry as the file to correct it.
Using BandMath in S1TBX I am able to export the incidence angle.
However, to batch this processing with a lot of data I would like to do it using gpt command line may be with BandMaths or subset but I fail to to that.
Have you any idea to do that ?
