LiDAR and Drone Acquisition in Martigny

Following the rockfall event that happened on 15 March 2023 at Forclaz Road and surroundings in Martigny, RISK Group team (Tiggi C, Antonin C, and Liu Wei) did some acquisitions using a terrestrial LiDAR and a drone on 23 March 2023 to identify the source zone and try to reconstruct this event. Two blocks are identified on the road and also some of them stopped in the vineyard. This rockfall has affected not only the road and the vineyard, but also hit a park area and a restaurant nearby.
