The Enmap German Imaging Spectroscopy Mission: Status and Summary of Preparatory Activities

Abstract

The Environmental Mapping and Analysis Program (En-MAP) is an spaceborne imaging spectroscopy mission under development by a consortium of German Earth Observation research institutions. The core payload of EnMAP consists of a dual-spectrometer instrument measuring in the optical spectral range between 420 and 2450 nm with a spectral sampling distance varying between 5 and 12 nm and a reference signal-to-noise ratio of 400:1 in the visible near-infrared and 180:1 in the shortwave-infrared parts of the spectrum. EnMAP images will cover a 30 km wide area in the across-track direction with a ground sampling distance of 30 m. An across-track tilted observation capability will enable a target revisit time of up to 4 days at Equator and better at high latitudes. EnMAP will contribute to the development and exploitation of spaceborne imaging spectroscopy applications by making high-quality data freely available to scientific users worldwide. In this talk we will provide an overview of the mission status including both technical developments and preparatory activities for the implementation of the EnMAP scientific program.
