I a have two questions:
1- I was wondering if there is a need for co-registration if I want to do a multi-temporal analysis
2- After which step in pre-processing I can clip my Sentinel-1 raster data to my study area (by a vector) to save some time in other pre-processing time?
Thanks for your reply in advance
When it comes to your second question, If you work with SLC, your first have to apply an orbit file. After that I’d recommend to deburst, and after that you can do your subsets. Since your data not terrain corrected yet, you would have to find your target area mostly by random guessing.
Update: you also could start from splitting and do all the rest after.
