Abstract
The high-resolution imaging spectroscopy remote sensing mission EnMAP (Environmental Mapping and Analysis Program, enmap.org) will cover the spectral range from 420 nm to 2450 nm with a spectral sampling distance varying between 5 nm and 12 nm. A smile effect, which is a spectral shift across the swath, of at most 0.2 pixels is expected. The OHB System AG realizes the satellite with the hyperspectral push-broom imager and the on-board characterization equipment including a doped sphere for spectral calibration. The Earth Observation Center (EOC) of the German Aerospace Center (DLR) is responsible for the operational in-flight calibration and realizes the fully-automatic on-ground processors including methods for smile correction. A smile correction taking the spectral calibration into account as well as a simplified atmospheric compensation will be analyzed.
