How to remove dark/zero padded regions from Sentinel-1 rslc/diffs?

Added by Kaushik Biswas over 4 years ago

Dear GAMMA users,

I came across some Sentinel-1 SLCs where some extra zero padding or dark regions on the edges were prepended. The same reflects in the resampled SLCs ("*.rslc") and differential interferograms ("*.diff") produced by S1_coreg_TOPS.

Is there any command/script in GAMMA to fix (remove) this for each rslc and diffs?

PS: I am attaching a rslc and a diff for the illustration of this problem.

Regards,
Kaushik
