Hi Everyone, I am curious if anyone could give me some guidance into a method for aligning two UAV orthomosaics from different dates. There are slight distortions in there mosaics which are respectively unique. They are taken over the same crop field, but the GPS accuracy has given a misalignment. Because of the distortions, some sort of a warp transformation may be needed to get a desired pixel-to-pixel alignment. Are there any tools within ENVI that could possibly help with this issue? Much thanks, Alex
