I am trying to collocate a coherence image with a sentinel-2 image, the region that I am trying to collocate is in the High mountain Asia. For some reason, there is a major noticeable shift in the final result. My steps were as follows :
- Create a coregistered stack
- Calculate coherence using the Coregistration tool
- Subtract flat-earth phase and subtract the topographic phase by using external DEM (ALOS world 3D)
- Perform collocation using the collocation tool.
