Session Abstract
This course is a basic introduction to the study of discontinuities via remote sensing derived datasets. To analyse the stability of the slope or estimate a geomechanical quality index, it is required to know the number of discontinuities sets and their orientations, among other parameters. Traditional methods comprise the direct access to the surface, which can be a risky (or even impossible) task. However, remote sensing techniques, such as ground-based 3D laser scanning or Structure-from-Motion, provide information of the ground surface. The data is usually a 3D point cloud (3DPC) of a surface. These points represent the discontinuities, weathered surfaces, or the existing vegetation. In this course, we will analyse a case study of a rocky slope to extract: (1) the number of discontinuity sets and (2) their orientation, classifying accordingly the 3DPC. The course will use open-source software (CloudCompare) and Discontinuity Set Extractor (MATLAB-based) to identify the discontinuity sets and obtain their orientation.
