This volume presents a broad overview of the requirements, capabilities, challenges and future directions of spaceborne imaging spectroscopy to explore the Earth's surface for a range of application domains. These include mine exploration, soil mapping, vegetation monitoring, mapping of pollution and hazardous materials, inland and coastal water monitoring, urban applications and others. Imaging spectroscopy, also often termed hyperspectral remote sensing, for terrestrial Earth observation dates back to the 1980s, when the first spectrometers observing in the visible to shortwave infrared wavelength range were deployed on airborne platforms. From the end of the 1990s onwards, spaceborne hyperspectral missions have demonstrated the capability to provide information on the composition and biochemical and physical characteristics of the Earth's surface. Today, several hyperspectral spaceborne missions are under development to be launched within the next few years. It can be expected that future global and frequent coverage of the Earth's surface with spaceborne imaging spectroscopy data will bring a major advance in the information depth that future Earth system models and monitoring service developments can be based on.
