Terrestrial Laser Scanning as road’s Cadastre revision and integration support

Topography and Photogrammetric Section of Civil Engineering Department of University of Pisa, in cooperation with Centre of Excellence TeleGeomatics of University of Trieste, is experimenting laser data’s integration with collected data by MMS (Mobile Mapping System) vehicles. That vehicles are being used by the two research centres on road’s cadastre. Two different laser scanners are used for experiments, the Riegl LMS-Z210i and the Optec ILRIS-3D. The survey concern different kinds of road’s elements and a pair of road’s intersections. Test have been carried out aiming at the review the potential and productivity of laser use in comparison with classic survey’s technique. Some examples of data collection and processing are described. Survey are realised both with instruments on the ground both with laser located on top of VINCI’S (Vehicle Vehicle-borne Integrated Navigation and Cartographic Information Prime System), the MMS vehicle of University of Pisa
