EnMAP (Environmental Mapping and Analysis Program) will be the first German optical earth remote sensing mission in orbit. It will acquire high quality hyperspectral image data with 232 spectral channels in the solar-reflectance range on a frequent basis with high geometric resolution. The major objectives of the mission are to measure, derive, and analyze numerous diagnostic parameters which describe vital processes on the earth’s surface relating to agriculture, forestry, soil and geological environments, as well as coastal zones and inland waters. During operations the mission will provide information about the status of different ecosystems and their response to natural or man-made changes in the environment. The mission management is led by the Space Agency of the German Aerospace Center (DLR). The scientific aspects of the mission are covered by the German Research Centre for Geosciences (GFZ). The Kayser-Threde GmbH is responsible for the development, production, and launch of the satellite. The establishment and operation of the ground segment is performed by the DLR entities Earth Observation Center (EOC) and Space Operations and Astronaut Training (RB) . The ground segment is funded by the German Federal Ministry of Economics and Technology (BMWi).
