Hello everyone! I’m planning out a processing workflow prior to receiving data, but have some questions on the order of operators and their effects. The data will be Radarsat-2 Quad-pol and Sentinel-1 Dual-pol. The preprocessing I’d like to perform includes:
Radiometric Terrain Flattening
My questions are:
- Does Radiometric Terrain Flattening also perform orthorectification?
- What order should I take these steps in? I’ve seen some threads say that orthorectification should come at the very end; is this still the case when performing polarimetric processing? (If RTF & Ortho are linked, this seems problematic)
- Assuming RTF doesn’t orthorectify, what is the consensus tool for performing orthorectification?
- Am I missing any recommended steps? Are any of these steps unnecessary?
I do not yet have the data , so unfortunately I can’t point to anything specific at this time. However, I greatly appreciate any clarification, and hope this post could serve as a general process-flow for others as well. Thank you!
