They all interact with light in their own, characteristic way … … from ultraviolet light to the visible light that we can see with our eyes to the near- and short-wave infrared all the way to microwaves, all being part of the same total electromagnetic spectrum. All surface materials have their own characteristic reflectance spectra by which they can be differentiated and, to some extent, quantified. Such detailed information in hundreds of contiguous bands can only be captured by hyperspectral instruments. Hyperspectral sensors measure many spectra that compose an image data cube. While the current availability of hyperspectral image data is still limited in both temporal and spatial coverage, data availability is expected to increase substantially in the near future with the launch of spaceborne imaging spectroscopy missions such as PRISMA and EnMAP. They will provide high accuracy imaging spectroscopy data of the earth surface in a timely and frequent manner letting us explore “beyond the visible” and contribute to solving complex environmental challenges. Be part of that remote sensing revolution and our growing hyperspectral community. In this 5 hrs MOOC, learn the principles of imaging spectroscopy as well as sensor technologies and data acquisition techniques and expert-led hands-on training. This course was created by the GFZ Potsdam as part of the EnMAP science program of the German Space Agency at the DLR and supported by experts at various partner institutions.
