The EnMAP hyperspectral imager—An advanced optical payload for future applications in Earth observation programmes

Abstract

The Environmental Mapping and Analysis Program (EnMAP) is a joint response of German space industry, Earth observation research institutions and value-adding (VA) resellers. EnMAP fulfills the increasing demand on accurate, quantitative information about the evolution of terrestrial ecosystems. The payload consists of an imaging hyperspectral instrument covering the visible, near- and short-wave infrared wavelengths. EnMAP will provide high quality, standardized, and consistent data on a timely and frequent basis. The mission's primary focus will be on the considerable improvement of already standardized products and the development of new quantitative and subsequently highly informative data and its derivatives. The advanced hyperspectral instrument on EnMAP can resolve and detect biophysical, biochemical, and geochemical variables in distinct detail. These data can only be derived from an EnMAP type instrument and will tremendously increase our understanding of coupled biospheric and geospheric processes and thus, enable the management and ensure the sustainability of our vital resources. The instrument data set allows for a detailed monitoring, characterization and parameter extraction of vegetation targets, rock/soils, and inland and coastal waters on a global scale.
