I am interested in finding the change in land cover particularly forests.
I am working with slc-off images (no other sensor images available for my study). I have done the gap-filling in Erdas Imagine using focal-analysis and it worked fine. I have to further atmospherically correct the images using FLAASH in Envi.
What is the right sequence of process work?
Atmospheric correction before gap-filling or Gap-filling before atmospheric correction?
