Airborne and Terrestrial Laser Scanning and geomorphology: possibilities, problems, and solutions

New Congress in Vienna:

European Geosciences Union
General Assembly 2010
Vienna, Austria, 02 – 07 May 2010

On this general assembly: "Airborne and Terrestrial Laser Scanning and Geomorphology" The session number is GM 2.2

"....Terrestrial Laser Scanning (TLS) is also increasingly applied for fast data capture of the surface, e.g., in detection and monitoring of mass movements and in other geomorphic studies requiring high accuracy and frequent repetition.
The application of both laser scanning technique results in data sets characterised by enormous data sizes, extremely high accuracy (up to cm-scale) and very high resolution. These properties compensate for the efforts invested in the data processing, however it means new challenges for the geomorphic evaluation. The wealth of laser scanning-derived DTMs can be used for geomorphic analyses in various forms (point cloud, TIN, grid) for analysis in flood-endangered regions, for natural hazard analyses like mass movements and are almost unbeatable in surface modelling of mountainous and karstic areas. They are also highly applicable in environmental change studies concerning the change in snow and ice coverage, soil creep, etc....."
