Hi everyone,
I downloaded a stack of Sentinel-1 SLC images. Of course, it take a large volume of disk space. But i just want to to do deformation extraction around a small area. So I deleted all the IW1 and IW3 subswath data and left only IW2, thus reduce the space burden. I followed the instructions to do interferometry by using SNAP. When I run the step “S-1 TOPS Split”, I encounter the error “Message: Source product should be multi sub-swath SLC burst product.”
Do you know any solutions to solve this problem. Or I cannot delete the other unnecessary subswaths at the beginning?
