Rock face surveys using a LiDAR MMS

Abstract

The analysis and prevention of natural hazards is one of the aims of the scientific community and those who are involved in managing the environment and territory. Terrestrial LiDAR and photogrammetric techniques are effective methods of acquiring environmental data and of integrating them in digital products. These techniques have shown remarkable effectiveness when the area of interest is limited. In this paper, the authors have attempted to resolve this problem by presenting an experimental vehicle that allows the extensive use of these techniques to survey rock faces. These procedures were then applied during a measurement campaign, which was conducted along a major international roadway (the Simplon Pass) near the Divedro Valley.
