I am trying to perform change detection using temporal SAR GRD image for flood inundation mapping. I have created graph that executes a Sentinel-1 GRD workflow for change detection that consists of following processing steps.

- Terrain flattening
- Range Doppler Terrain Correction
- Change detection
- I would like to know whether my approach is correct ? Thanks in advance.
