Digital Surface Modelling by Airborne Laser Scanning and Digital Photogrammetry for Glacier Monitoring
This research is part of a Swiss National Science Foundation project on “Mass Balance Determination of Glaciers with the Use of State-of-the-art Remote Sensing Methods and a Numerical Flow Model”. Remote sensing involves automated processing of aerial images and laser scanning and aims at producing glacier surface models with an accuracy of about 0·5-1 m in time periods of 1-5 years. The Untera...
متن کاملQuality Assessment of Dtm and Orthophoto Generated by Airborne Laser Scanning System Using Automated Digital Photogrammetry
The approach of using an airborne laser scanning for DTM generation has made great progress recently. However, it is not always clear the reliability and the quality of the geometry that characterise the generated DTM. Thus, a special test was conducted to assess the quality and the reliability of the generated DTM via an airborne laser scanning system. To perform this test, an airborne laser s...
متن کاملAccuracy Study of Airborne Laser Scanning Data with Photogrammetry
This paper describes an accuracy study of airborne laser scanning data obtained by the Airborne Topographic Mapper (ATM) laser system over Ocean City, Md. The ATM is a conical scanning laser altimeter developed by NASA for precise measurement of surface elevation changes in polar ice sheets, ocean beaches and drainage systems. First, we determine the “internal" accuracy of the system by compari...
متن کاملFusion of Terrestrial Laser Scanning and Digital Photogrammetry
Terrestrial laser scanners are introduced in the market in various construction forms, dispose of various measuring principles and are used in the most different areas of application. Combining the information of the gray-scaled point cloud with the geometry informations of rgb-colored images results in improved possibilities of object interpretation and measurement. The coalescence of both dat...
متن کاملIntegration of Digital Photogrammetry and Laser Scanning for Heritage Documentation
Within the paper the potential of combining terrestrial laser scanning and close range photogrammetry for the documentation of heritage sites is discussed. Besides improving the geometry of the model, the integration aims on supporting the visual quality of the linear features like edges and cracks in the historical scenes. Although the laser scanner gives very rich surface details, it does not...
