 The Environmental Mapping and Analysis Program, NMAP, is a German satellite mission designed to provide high-quality data for Earth remote sensing. It will use two spectrometers to measure the light interacting with Earth's surface materials and processes, providing information about the composition, structure and dynamics of the planet. NMAP will be able to image a 30 kilometers wide swath of land with a resolution of 30 meters per pixel, allowing scientists to study the composition and properties of Earth's surface in unprecedented detail.
