Monitoring
 
 

Using the JointMetriX3D system landslides can be acquired three-dimensionally also from larger distances (several hundreds of meters - over one kilometre). Prerequisite is free sight from two imaging locations to the surface to monitor. Usually, reference points are applied in the area of interest before a measurement campaign starts. Th reference points serve as tie points in order to bring subsequent 3D images into the same co-ordinate system.

The repeated application of the system allows the determination and visualisation of eventual displacements, material transport, volume of transported material, or areas of decreasing material or its accumulation. The tool might also support to estimate the deformation mechanism of a large landslide.
