The actual implementation of the Virtual Forest refers to diverse data sources from different producers. The remotely sensed data here play a pivotal role. Among other things, the HRSC-/MFC stereo camera of the German Aerospace Center as well as alternative matrix cameras, which generate a high-resolution RGB- and infrared orthophotos, are inserted. Expanded are those pictures by a further infrared channel recorded from the satellite SPOT. For recording the terrain model (e.g. forest soil) as well as the surface model (e.g. snag) laser scanner are used.
