This paper provides a comprehensive review of the application of Light Detection and Ranging (LIDAR) techniques in landslide investigations. It covers the historical development of LIDAR technologies, their principles, and their classification into four main categories: detection and characterization of mass movements, hazard assessment and susceptibility mapping, modeling, and monitoring. The paper highlights the potential of LIDAR-derived High-Resolution Digital Elevation Models (HRDEMs) in investigating various types of landslides, including rockfalls and debris flows. While HRDEMs are not yet widely used in landslide investigations, they offer new opportunities for research and application. The paper also discusses the limitations and challenges associated with LIDAR data, such as the need for post-processing techniques and the complexity of integrating LIDAR with other remote sensing techniques. Overall, the review emphasizes the growing importance of LIDAR in landslide studies and the potential for further advancements in this field.This paper provides a comprehensive review of the application of Light Detection and Ranging (LIDAR) techniques in landslide investigations.
