The Environmental Mapping and Analysis Program (En-MAP) is a German built hyperspectral space sensor scheduled for launch in 2012. EnMAP will measure over the 420-2450 nm spectral range at a varying spectral sampling of 5-10 nm. Images will covered 30 km×30 km areas at approximate pixel sizes of 30 m. The primary goal of EnMAP is the exploitation of hyperspectral data for the derivation of highspectral resolution observations of biophysical, biochemical and geochemical variables from a range of surface covers, such as vegetation canopies, rock and soil targets and coastal waters, on a global scale. General descriptions of the EnMAP instrument, the satellite operation concept, the data processing and archiving structures and current project development activities are provided in this paper.

The Environmental Mapping and Analysis Program (EnMAP) is a German space based hyperspectral mission planned for launch in 2012. The hyperspectral instrument covers the wavelength range from 420nm to 2450nm using a dual spectrometer layout. Both f/3 spectrometers employ a prism disperser for maximum throughput and are linked to the common foreoptics by a micromechanical field splitter. Together with custom designed silicon and MCT-based detector arrays this sensor design exhibits a peak system SNR of 1000 at 495nm and of more than 300 at 2200nm. Stable and precise in orbit performance is ensured by a multi loop thermal control system and a system calibration which relies on onboard sources as well as a full aperture diffuser.
