“Airborne LiDAR (light detection and ranging) data can be used for fine-scale landslide characterization. New advances in data analysis of multi-temporal LiDAR provide the ability to monitor changes in landslides over time. This research is focused on leveraging LiDAR data and a multi-temporal analysis for a small landslide in southern Idaho. The analysis demonstrates the ability to monitor both horizontal and vertical movement over time. Field based analyses were performed to validate the LiDAR results. With a careful error analysis, a volume estimate of mass movement over time is made. Visualization of the multi-temporal LiDAR point clouds is used to minimize error and identify dominant earth surface processes. The methods and results can be directly transferred to other landslides.”
