First of, these are my first hours in this forum, and in SAR learning as well.
I am learning how to do Change Detection using Sentinel-1, try to get same accuracy as with Sentinel-2.
Now I am stuck at Coregistration (or stacking) of two time GRD images, using SNAP 5.0.3
Coregistration > Stack Tools > Create Stack ==> output is misaligned;
Coregistration > DEM Assisted Coregistration > DEM Assisted Coregistration ==> output is blank.
Could you all give me some teaches, what is better way to do.
BTW, my field is about forest change detection, it shall be highly appreciated if someone give me a tut.
Thank you very much.
