“…EnMAP is expected to become a key system in the field of spaceborne imaging spectroscopy in potential co-existence with other comparable and complementary missions, such as the Japanese Hyperspectral Imager Suite (HISUI) [42], the Italian PRISMA (Hyperspectral Precursor of the Application Mission) [43], the USA's Hyperspectral Infrared Imager (HyspIRI) [44], the French HYPXIM [45] and the Italian-Israeli SHALOM (Spaceborne Hyperspectral Applicative Land and Ocean Mission). Even though no coordination between different missions for the optimization of acquisitions is foreseen, imaging spectroscopy users will benefit from the larger diversity of data sources.…”

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.

Abstract:The imaging spectroscopy mission EnMAP aims to assess the state and evolution of terrestrial and aquatic ecosystems, examine the multifaceted impacts of human activities, and support a sustainable use of natural resources. Once in operation (scheduled to launch in 2019), EnMAP will provide high-quality observations in the visible to near-infrared and shortwave-infrared spectral range. The scientific preparation of the mission comprises an extensive science program. This special issue presents a collection of research articles, demonstrating the potential of EnMAP for various applications along with overview articles on the mission and software tools developed within its scientific preparation.

“…These results suggested the effectiveness and potential of the presented hyperspectral and multispectral image fusion method. The contribution is a synergetic use of future EnMAP and Sentinel-2 data resulted in a spatial definition in geological exploration finer than those of the current and near future satellite missions such as EnMAP, the Japanese Hyperspectral Imager Suite (HISUI) [47], the Italian PRISMA (Hyperspectral Precursor of the Application Mission) [48], the US Hyperspectral Infrared Imager (HyspIRI) [49] and the French HYPXIM [50]. Naturally, the image fusion technique presented in this work can be extended to conventional applications such as detailed land cover classification and target detection; and with the enhanced data at 10 m GSD, there are potentially new applications that have not been anticipated for spaceborne hyperspectral remote sensing before.…”

Potential of Resolution-Enhanced Hyperspectral Data for Mineral Mapping Using Simulated EnMAP and Sentinel-2 Images

2016

Spaceborne hyperspectral images are useful for large scale mineral mapping. Acquired at a ground sampling distance (GSD) of 30 m, the Environmental Mapping and Analysis Program (EnMAP) will be capable of putting many issues related to environment monitoring and resource exploration in perspective with measurements in the spectral range between 420 and 2450 nm. However, a higher spatial resolution is preferable for many applications. This paper investigates the potential of fusion-based resolution enhancement of hyperspectral data for mineral mapping. A pair of EnMAP and Sentinel-2 images is generated from a HyMap scene over a mining area. The simulation is based on well-established sensor end-to-end simulation tools. The EnMAP image is fused with Sentinel-2 10-m-GSD bands using a matrix factorization method to obtain resolution-enhanced EnMAP data at a 10 m GSD. Quality assessments of the enhanced data are conducted using quantitative measures and continuum removal and both show that high spectral and spatial fidelity are maintained. Finally, the results of spectral unmixing are compared with those expected from high-resolution hyperspectral data at a 10 m GSD. The comparison demonstrates high resemblance and shows the great potential of the resolution enhancement method for EnMAP type data in mineral mapping.
