Atmospheric correction of DAIS hyperspectral image data

Abstract

A software package for the atmospheric correction of airborne hyperspectral and multispectral image data has been developed at DLR. Reflective and thermal spectral channels are taken into account employing the MODTRAN code to calculate the radiative transfer. A list of four airborne sensors is included currently in a menu-driven user-friendly environment. New instruments may be added easily. This paper focuses on the algorithms employed for the processing of DAIS imagery. The DAIS is a digital airborne imaging spectrometer with 79 bands covering the optical spectrum from the visible to the thermal infrared region.
