“…Optical imaging spectroscopy or hyperspectral remote sensing for Earth observation relies on the use of spectrometers for the measurement of the solar radiation reflected by Earth system components in contiguous spectral channels [1,2]. The reconstruction of atmospheric and surface absorption features from spectroscopic measurements enables the identification and quantification of land, water and atmosphere constituents with characteristic spectral signatures, which makes imaging spectrometers suited for a wide range of Earth observation applications.…”

Imaging spectroscopy, also known as hyperspectral remote sensing, is based on the characterization of Earth surface materials and processes through spectrally-resolved measurements of the light interacting with matter. The potential of imaging spectroscopy for Earth remote sensing has been demonstrated since the 1980s. However, most of the developments and applications in imaging spectroscopy have largely relied on airborne spectrometers, as the amount and quality of space-based imaging spectroscopy data remain relatively low to date. The upcoming Environmental Mapping and Analysis Program (EnMAP) German imaging spectroscopy mission is intended to fill this gap. An overview of the main characteristics and current status of the mission is provided in this contribution. The core payload of EnMAP consists of a dual-spectrometer instrument measuring in the optical spectral range between 420 and 2450 nm with a spectral sampling distance varying between 5 and 12 nm and a reference signal-to-noise ratio of 400:1 in the visible and near-infrared and 180:1 in the shortwave-infrared parts of the spectrum. EnMAP images will cover a 30 km-wide area in the across-track direction with a ground sampling distance of 30 m. An across-track tilted observation capability will enable a target revisit time of up to four days at the Equator and better at high latitudes. EnMAP will contribute to the development and exploitation of spaceborne imaging spectroscopy applications by making high-quality data freely available to scientific users worldwide.

“…As a signal is transmitted, reflected, and scattered again by interacting with the various components of the atmosphere and surface; the reflectance spectra analysis may allow recognition or quantification of the materials. It can be used in several applications such as environmental, geographic, and military applications [1,2].…”

“…It acquires image in a large number (typically over 40), narrow (typically 10 to 20 nm in width) and contiguous spectral bands to enable the extraction of reflectance spectra at a pixel scale, so it can produce data with sufficient resolution for the direct identification of those materials with diagnostic spectral features (Goetz et al, 1985). The objective of hyperspectral remote sensing is to measure quantitatively the components of the Earth System from calibrated spectra acquired as images for scientific research and applications (Vane & Goetz, 1988). The rationale behind this technology for geological applications is that mineral species have diagnostic absorption features from 20 to 40 nm wide in electromagnetic wavelength ranges which is larger than hyperspectral spectral resolution (van der Meer & Bakker, 1997).…”
