Modern techniques of acquisition of high resolution digital elevation model (HRDEM) open new field of researches in terrain analysis. Now HRDEM can be easily acquired either by airborne or terrestrial LIDAR (Light Detection And Ranging). HRDEM permit new monitoring methods, geomorphic and morphometric analysis such as:
- Identification of present and past instabilities by simple visual inspection of shaded relief.
- HRDEM time series for monitoring and analysis of movements and processes of entire slopes.
- Detailed structural analysis, a fundamental step for the rock slope stability analysis.
- Erosion quantification of slope and river processes using ground base LIDAR.
- Detection of unstable volumes at several scales and estimation of their distributions.
- Determination of sliding surfaces geometry and roughness, from submillimetric to "mountain side" scales

This session has a main goal to give the opportunity to geohazard analysts to share their experiences on HRDEM. Contributions from a wide range of topics are welcome, such as:
- new case studies using HRDEM (off- or onshore, surface or underground, etc)
- methods and software development related to HRDEM and landslides
- application of recent technical technical developments, such as full-wave or hyperspectral-lidar coupling, to geohazards
