Overview
ATCOR-4 is an airborne atmospheric and topographic correction software for wide FOV optical scanner data. It includes separate modules for flat and rugged terrain, a monochromatic database compiled with Modtran-5, and supports solar (0.35-2.55 µm) and thermal (8-14 µm) spectral regions. Features include aerosol and water vapor mapping, haze removal, inflight calibration, and TOA radiance simulation.
