On the acquisition of geometric and semantic data of the Kachelotplate by means of airborne and terrestrial LIDAR

摘要

In autumn and spring 2007, geometric and semantic data were acquired by means of airborne laser-scanning and terrestrial laserscanning. The aerial flight with a helicopter enabled capturing of the entire Kachelotplate while the terrestrial laserscanning was used for a selected geographically relevant area. The acquired data was individually evaluated, analysed and transferred to a geographical information system. Since data from several epochs is available, it is possible to make valid statements about dislocations of the Kachelotplate, to execute mass computations and to calculate profiles and surrounding polygons.
