On May 1st, the SYSSIFOSS project has started and first test scans have already been conducted in the forest. Experciences from these initial testings serve as a basis for many field campaigns this summer which aim at the acquisition of high-density point clouds of 140 single trees with a RIEGL VZ-400 terrestrial laser scanner. Moreover, first scans have been acquired with a RIEGL miniVUX-1 UAV laser scanner, which is part of the 3DGeo group’s brand-new UAV-borne LiDAR system. These point clouds will be used for the validation of species-specific tree models derived from airborne laser scanning.
SYSSIFOSS is a joint project between the Institute of Geography and Geoecology (IFGG) of the Karlsruhe Institute of Technology (KIT) and the 3DGeo Research Group of Heidelberg University.
In this project a new approach to create synthetic LiDAR data is suggested by combining the outputs of an established forest growth simulator with a to-be-created database of species-specific model trees extracted from real LiDAR point clouds. This approach will result in inventory information at the single tree level and a matching 3D forest structure for large areas.
The project is funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) – Project number: 411263134.
