Recent Progress and Developments in Imaging Spectroscopy

The Special Issue (SI) on “Recent Progress and Developments in Imaging Spectroscopy” is a collection of contributions presented at the 10th Workshop of the European Association of Remote Sensing Laboratories (EARSeL) Special Interest Group on Imaging Spectroscopy (SIG IS), which took place at the University of Zurich, Zurich, Switzerland, between 19 and 21 April 2017. [...]the SI was equally open to the global research community actively involved in imaging spectroscopy. Increasing awareness and capacity for accurate sensor calibration and rigorous product validation by an expanding research community [1] and innovative approaches integrating different Earth observation technologies (e.g., LIDAR, spectroscopy, etc.) allow for novel observations of the Earth system [2,3,4]. New sensor developments in space will provide future spectroscopy data for key observations of the Earth’s spheres (e.g., the EnMap mission (DLR), the PRISMA mission (ASI), the Fluorescence Explorer mission (ESA), the Hyperspectral Imager Suite (HISUI) mission (Japanese Ministry of Economy, Trade and Industry) onboard the International Space Station (ISS), or the European Copernicus Programme expansion Sentinel candidate CHIME). [17], the authors compare wavelength calibration approaches and develop recommendations for the spectral characterization of field fixed-point spectrometers used for reflectance and sun-induced fluorescence (SIF) measurements in support of the European Space Agency (ESA) Fluorescence Explorer (FLEX) mission.
