During the Open Air Festival "Rock am Ring" a multisensory dataset was acquired on 6th of June 2014 by DLR's airborne radar system F-SAR on the Dornier Do 228 and the optical camera system 3K on the Cessna 208B Grand Caravan, both operated simultaneously on-board of the two aircrafts. This dataset allows for the comparison and fusion of fully polarimetric radar data and optical data and provides data for a number of remote sensing applications. In the frame of the VABENE++ project, these applications are for instance traffic monitoring, the occupancy assessment of parking space, camp grounds and assembly areas for rescue forces. In addition, by comparing these datasets with a different dataset from the same area acquired several weeks before, further remote sensing methods can be investigated and refined. These methods are for instance change detection and the generation of precise digital elevation and terrain models.
