In this regard several new generations of Earth Observing (EO) advanced spaceborne hyperspectral sensors were launched and others are in preparation. Recent launches include the German Aerospace Center’s (Deutsches Zentrum fur Luft- und Raumfahrt; DLR’s) Earth Sensing Imaging Spectrometer (DESIS) integrated into and onboard the International Space Station’s (ISS) Multi-integrated into User-System for Earth Sensing (MUSES) platform, the Italian Space Agency (Agenzia Spaziale Italiana, ASI’s) PRISMA (PRecursore IperSpettrale della Missione Applicativa), Japanese HISUI (Hyperspectral Imager Suite) onboard ISS, India’s HysIS (Hyperspectral Imaging Satellite), China’s Advanced Hyperspectral Imager (AHSI) aboard China's GaoFen-5 (GF-5) satellite, and China’s Jilin Hyperspectral Satellite constellation. These will be followed by several hyperspectral missions coming up for launch such as the German DLR’s the Environmental Mapping and Analysis Program (EnMAP) to be launched soon, NASA’s Surface Biology and Geology (SBG) mission (formerly HyspIRI mission), EMIT from NASA, CHIME from ESA FLEX of ESA, SHALOM from ASI-ISA and more others from private players. These sensors will collect data in hundreds of wavebands and, typically, across the entire visible near and short infrared spectral range (400 to 2500 nanometers ) or part of it, and in 30 m or better GDS. Such data captured as “spectral signatures” leading to spectral libraries will be (and is) a quantum leap in data of the Planet Earth relative to older generation multispectral sensors such as the Landsats and Sentinels which have provided great service in the study of the Planet Earth over last few decades. Nevertheless, such data also provides great challenges in terms of data analysis, algorithm development, and application development.
