Photogrammetric methods are promising tools to monitor and characterize complex geomorphological and structural discontinuities in those areas where field mapping and terrestrial photogrammetry is not feasible due to unsafe/near-vertical slope or complex geometry. This study presents investigation, characterization, and 3D point cloud generation of a landslide using 191 photos collected from a DJI Phantom-3 Advanced unmanned aerial vehicle (UAV). We have used the structure-from-motion method to generate a 3D point cloud representing the outcrop from the acquired images and videos.
