Sketch Fab Virtual Outcrop Model

This is a subsampled segment of the Virtual Outcrop Model (VOM) Point Cloud of Creux-du-Van (Central Internal Jura), acquired using the Long Range 3D Laser Scanning System RIEGL VZ-2000i. The data was collected by the Detect-Deformation & Tectonics Group at the University of Lausanne (UNIL) in October 2023. The average resolution of the point cloud is 0.5 meters.
