The application of airborne LiDAR system in geological disasters

Airborne LiDAR System is a laser detection and ranging system for quickly obtaining high-precision, high-density three-dimensional coordinate data. The target information after the geological disasters can be victimized for disaster assessment and decision analysis to provide effective support, LiDAR provides a new technical means for disaster mitigation, relief works. This paper focuses on the application of airborne LiDAR system in geological disasters, it summarizes some experience of the LiDAR point data acquisition and processing, and the results of the LiDAR point data.
