The Imaging Spectroscopy Mission Enmap–Its Status and Expected Products

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 4.8 nm and 12.0 nm. It will acquire 30 km in the across-track direction with a ground sampling distance of 30 m and the across-track tilt capability of 30° will enable a target revisit time of less than 4 days. The launch is scheduled for 2020. The high-quality products will be freely available to international scientific users for measuring and analyzing diagnostic parameters which describe vital processes on the Earth’s surface. Based on the status of all segments of the mission the expected image product quality is analyzed and thereby it is illustrated how the requirements are met. The methodology relies on precise simulations of image acquisitions and the independently realized fully-automatic on-ground processing chain.
