The “Hyperspectral Remote Sensing” team provides methods and products for optical imaging sensors on satellites and aircrafts.
In the area of spaceborne missions, operational fully-automated systems for processing image data are developed for ground segments. Currently, these processing chains are applied for the German hyperspectral mission EnMAP (Environmental Mapping and Analysis Program) and for the American-German hyperspectral mission DESIS (DLR Earth Sensing Imaging Spectrometer) , installed on the ISS (International Space Station). The processing of these image data thereby includes the:
The standardized products created in this process form the basis for deriving higher-level products for a wide range of applications. For this purpose, the team develops the following methods for multi- and hyperspectral images and time series of images, for example:
Further projects continue to develop these and other methods for various future optical missions for Earth surface observation.
A process chain comparable to EnMAP and DESIS is used in CATENA for the airborne mission HySpex
