Processing Chain for the Future Hyperspectral Mission EnMAP

Abstract

The Applied Remote Sensing Cluster of the German Aerospace Center (DLR) is responsible for the establishment of the payload ground segment while the GeoForschungsZentrum Potsdam (GFZ) is in charge for the development of the science group and its activities for the future German hyperspectral satellite mission EnMAP (Environmental Mapping and Analysis Program), which is planned to be launched in 2012. EnMAP covers the electromagnetic spectrum from 420 nm to 2450 nm with a spectral resolution of at least 10 nm and a spatial resolution of 30 m × 30 m with a swath width of 30 km. The primary goal of EnMAP is to quantify and analyze diagnostic parameters describing key processes on the Earth’s surface during the five years of mission operations. The main focus here is on the processing chain which will obtain standardized products including radiometric, geometric, and atmospheric corrections. Extensive calibration and validation activities are foreseen to achieve high-quality and consistent data with respect to the same and other missions.
