Combining terrestrial and uav-borne scan data in an archaeology application

RIEGL, along with the scientific support from the Ludwig-Boltzmann Institute in Vienna, conducted an extensive surveying campaign at the ruins of the medieval castle Gars in Lower Austria. For data acquisition, the RIEGL VZ-400i and 2000i 3D terrestrial laser scanners 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. www.riegl.com
