The group is responsible for those sensor-related tasks of the Earth Observation Center (EOC) that relate to hyperspectral technology. This includes characterising hyperspectral sensors in the lab, developing calibration software, and validating the methods developed as well as the measurement data obtained from the sensors. This methodological work is based on over thirty years of expertise.
For the experimental work well-equipped optic labs and imaging and non-imaging spectrometers are available for use in the lab, in the field, on UAVs and in aircraft. The Calibration Home Base (CHB), which has ISO 9001 certification, is the only facility available Europe-wide also to external users, in which large, heavy hyperspectral sensors can be precisely characterized radiometrically, geometrically and spectrally, from near UV to shortwave infrared. For example, the institute’s HySpex aircraft sensor is characterised there. HySpex is used by the OpAiRS user service to obtain hyperspectral remote sensing data throughout Europe.
Validation of sensor calibration takes place in the laboratory. Measurement campaigns are conducted in cooperation with partners to validate measurement data from remote sensing sensors on satellites, aircraft, and UAV. In addition, together with other IMF departments the team covers the entire processing chain from data acquisition and validation to data analysis in the area of remote sensing of water bodies.
