Hi all. I have many Envisat acquisitions which I would like to use for interferometry and I would like to apply speckle filtering before coregistering the images. I have created a subset for my intended master image and have applied the speckle filter to this and I am already noticing improved coherence. I was wondering, then, is there a way to perform speckle filtering for all the other images but only for the area constrained by the subset of the first image? I would like to avoid creating the same subset area for each individual image as I think this would be very time consuming!
Thanks in advance!
