I am using SLC-IW products of S1a &b. So, to coregister my chosen pair, I use S1 TOPS Coregistration. As mentioned by you, I located the InSAR Stack for overview but the ‘Coregistration Residuals’ section doesn’t show anything (screenshot attached ). I wonder why. The ‘Stack information’ section has the names of 2 products that have been stacked together. What could be the problem in this case?
you are right - I tested it and don’t see any as well. Sorry, I just expected the information would be there.
You can apply TOPS Split and Deburst and perform the “normal” coregistration on the outcomes just to get a coarse Idea on the correctness. For interferometry I would still proceed with the TOPS coregistered product.
That’s alright. And thanks for trying it out yourself. I shall get the residuals from ‘normal’ co-registration option. That should help me get an idea, but I may not be able to report them in a document.
