Airborne 3D Laser Scanner is a rapid, highly accurate and efficient method to generate data of large areas, industrial plants, entire urban areas, and more. Using Airborne 3D Laser Scanner in Photogrammetry mapping supports low bugget and provide high accuracy.
Typical applications of Airborne 3D Laser Scanner including Aerial Photogrammetry:
Topography & Corridor Mapping
City Modeling
Street Mapping, Railroad Mapping
Mapping of Lakesides and River Banks
Flood Management
Agricultural and Forestry Applications
The application of Airborne 3D Laser Scanner, to determine spatio-temporal velocity fields at the glacier tongue of Jacobshavn Isbrae using photogrammetric methods. In 2004, a measurement campaign has been conducted in order to determine the glaciers movement characteristics using image sequence analysis. Velocities up to 40 m/d could be observed. In a second campaign in 2007, multitemporal terrestrial 3D laser scanner data were acquired in addition to the high-resolution terrestrial image sequences with the goal of determining glacier surface velocity fields. A cross correlation technique for the determination of glacier surface velocity vectors is developed. We address some specific technical problems and describe a scheme for correcting timing and angular reference effects on the data. Finally glacier surface velocity fields obtained from the new described method using 3D Laser Scanner.
