Zusammenfassung |
A methodology of magnitude estimates for debris flow events is described
using airborne LiDAR data. Light Detection And Ranging (LiDAR) is a widely
used technology to generate digital elevation information. LiDAR data in
alpine regions can be obtained by several commercial companies where the
automated filtering process is proprietary and varies from companies to
companies. This study describes the analysis of geomorphologic changes using
digital terrain models derived from commercial LiDAR data. The estimation of
the deposition volumes is based on two digital terrain models covering the
same area but differing in their time of survey. In this study two surveyed
deposition areas of debris flows, located in the canton of Berne,
Switzerland, were chosen as test cases. We discuss different grid
interpolating techniques, other preliminary work and the accuracy of the used
LiDAR data and volume estimates. |
