The EnMAP imaging spectroscopy mission is designed to address a variety of application fields such as agriculture and forestry, ecosystem composition and dynamics, geology and soils, coastal and inland waters, and the cryosphere. Thanks to the rich spectral information contained in EnMAP measurements, it will contribute to an improved accuracy and robustness of parameter retrieval and potentially to the measurement of additional parameters not accessible with multispectral instruments. More than 30 years of airborne hyperspectral research have proven the potential to derive a large number of biochemical and geochemical parameters useful for addressing various environmental questions. However, most of these studies were limited to small selected areas and infrequent temporal coverage, preventing meaningful extrapolation. The prospect of hyperspectral data with large spatial coverage puts within reach the accurate assessment of many parameters at a regional scale, closing the current gap between in-situ or local measurements and their large-scale representation. Overall, EnMAP is expected to move many applications from a discrimination to an identification state and from a qualitative to a quantitative level.
Key applications of EnMAP include:
- Mine exploration and restoration
- Soil mineralogy
- Vegetation monitoring: plant stress, crop residues, plant composition
- Hazardous materials: oil, mine waste, pollutants, plastics
- Inland and coastal waters: phytoplankton composition, (harmful) algae species
- Urban surface materials
