I want to create DEM with S1, but my study cover two subswath.I have tried merge after interforgram and the DEM result show apparent difference at the boundary of subswaths.
Now I want to merge before interforgram,what’s the right steps? Before merging,deburst must be done,so merge should before or after coregistration?
1.split 2.deburst 3.merge 4.coregistration(including apply orbit file and back-geocoding) 5.interforgram
or
1.split 2.coregistration 3.deburst 4.merge 5.interforgram
which one is right?
and another question:what’s the difference between slice-assembly and mosaic?how to use them?
