Laser Scanning Airborne Systems -a New Step in Engineering Surveying (original) (raw)

The new laser scanning airborne technologies can be successfully used in engineering surveying and geodesy. They are mounted on light airplanes or on helicopters, have a fly speed comprised between 70 to 100 km/h; a height fly comprised between 50 to 100 m and can collect three-dimensional points with a density of 20 to 30 per meter. The advantages of these systems are: reduction of field work time, easy and safe access to objects (railway, roads), permit to create 3D homogeneous spatial data base, ensure the topographic and geodetic support for specific information systems.
