HySens - DLR's hyperspectral airborne campaigns 2000 - 2002

Abstract

Airborne imaging spectroscopy has undergone a rapid development over the last decade. The number of research groups making use of this technology has increased by an order of a magnitude. Starting from the late 1980ies at the DLR research center 'Oberpfaffenhofen' spectroscopic earth observation has been developed further in order to be able to provide reliable imaging spectrometer data to the scientific community. At the current stage the integrated hyperspectral facilities at DLR Cluster for Applied Remote Sensing consists of the two imaging spectrometers DAIS 7915 and ROSIS, a laboratory calibration facility and the respective processing and archiving facilities. As an additional important factor in airborne remote sensing access to a DLR-own fleet of research aircrafts (Dornier Do228, Cessna 208B Grand-Caravan, FALCON 20 E5 jet) is granted. Numerous imaging spectrometer campaigns have been carried out during the last years with flight activities all over Europe. Currently the two airborne imaging sensors are identified by the European Commission as a mayor research infrastructure and supported in a 3-years project (2000-2002) called HySens. In the frame of this project hyperspectral data sets have been acquired over different test areas proposed by international research teams (in total 23 user groups). In this paper the installation of the facility in an European research environment, the technical components as well as the research activities carried out over the past years will be described. Examples of already processed and delivered data will be shown. An outlook to future improvements will be given.
