Abstract

Landslide geomorphometric analysis based on high resolute Lidar
Track: 3D and Lidar Data
Authors: Stefano Crepaldi, Muriel Lavy, Marina De Maio

Using several Lidar data from airborne and terrestrial laser scanner we developed an integrated method to realize 3D morphodynamic model and map the landslide hazard.
Raster and tracking process analysis permit to detected terrain roughness, mass movements and volumetric balance. The dendritic terrain processing on the raw DEM allow to define a high resolute HydroDEM and the drainage density area influencing the landslide. Future targets of the work aim to stress the method in other case study.
