“…Another category includes large operational mapping missions such as the Copernicus Hyperspectral Imaging Mission for the Environment [19] and NASA’s Surface Biology and Geology mission (SBG) [20], which have the objective of providing global coverage at high temporal resolution to boost operational product generation and the commercial use of data to support economic growth. A third category comprises the various initiatives of cubesat constellations with imaging spectrometers on board, including the operating HyperSCOUT mission [21] and the planned CSIMBA mission [22]. Such missions investigate their capability to reduce revisit time and save high mission development costs, but also to test onboard data processing for the development of near-real-time products from spaceborne imaging spectrometers.…”

Imaging spectrometry from aerial or spaceborne platforms, also known as hyperspectral remote sensing, provides dense sampled and fine structured spectral information for each image pixel, allowing the user to identify and characterize Earth surface materials such as minerals in rocks and soils, vegetation types and stress indicators, and water constituents. The recently launched DLR Earth Sensing Imaging Spectrometer (DESIS) installed on the International Space Station (ISS) closes the long-term gap of sparsely available spaceborne imaging spectrometry data and will be part of the upcoming fleet of such new instruments in orbit. DESIS measures in the spectral range from 400 and 1000 nm with a spectral sampling distance of 2.55 nm and a Full Width Half Maximum (FWHM) of about 3.5 nm. The ground sample distance is 30 m with 1024 pixels across track. In this article, a detailed review is given on the applicability of DESIS data based on the specifics of the instrument, the characteristics of the ISS orbit, and the methods applied to generate products. The various DESIS data products available for users are described with the focus on specific processing steps. The results of the data quality and product validation studies show that top-of-atmosphere radiance, geometrically corrected, and bottom-of-atmosphere reflectance products meet the mission requirements. The limitations of the DESIS data products are also subject to a critical examination.

Emerging spaceborne hyperspectral technologies answer a growing need to comprehend the Earth and its atmosphere. These technologies constitute a reliable source of information about Earth's environment. The near real-time distribution of Earth Observation (EO) information can be a requirement for certain applications, such as early warning and disaster management systems.The last few decades have shown an increasing interest in hyperspectral observation data. This pushed the development of hyperspectral instrument technologies, also towards the miniaturization of instrument elements, taking advantage of electronics, new detector developments, material processes, hyperspectral filters, optical free-form design manufacturing and verification, on-board calibration techniques, on-board data processing and machine learning for image resolution enhancement. In parallel, the advent of smaller-size instruments, with lower development and operation costs is desirable to feed new data usage ideas and markets.ESA actively participates in the development of hyperspectral instruments, each to satisfy specific performance needs. Its participation spans from the shaping of a vision for an instrument, to the initiation of projects and missions, through the support of development activities, on to the instrument launch and subsequent tasks.The first hyperspectral instrument launched by ESA in 2001 was CHRIS, whose purpose was to improve knowledge on spectral reflectance from the Earth. Since then, the understanding of hyperspectral data and its significance has strongly risen and a sound heritage on hyperspectral instruments and applications exists by now. As for recent developments, a hyperspectral imaging mission study in the context of the Copernicus Expansion has been initiated and targets the realization of an instrument for routine observations in the visible-to-shortwave infrared range. In particular, it addresses the management of natural resources and enhances services for food security, sustainable agriculture and raw materials.The degree of innovation, compactness, overall technical challenge and user needs can constitute the starting constraint for each development objective. The evolving technologies enable compactness and a better instrument performance to expand the scope of its use. In order to give a comprehensible overview of the current hyperspectral imagers and technologies, opportunities and challenges, this communication sheds light on different instrument characteristics and design concepts in a categorized view and provides the current status of key technologies.
