The ruins of the medieval castle Gars in Lower Austria were documented in an extensive surveying campaign by RIEGL with the scientific support from the Ludwig-Boltzmann Institute, Vienna.
For data acquisition the RIEGL VZ-400i and 2000i 3D terrestrial laser sanners and the RiCOPTER, RIEGL’s remotely piloted airborne laser scanning system, as well as ground radar have been used. Terrestrial and airborne datasets have been registered together, images were automatically geo-referenced – the result is a comprehensive, highly accurate point cloud of the area providing numerous additional information and features.
