The airborne lidar is a new kind of remote sensing technology for collecting accurate three-dimensional coordinates on the surface by laser. In order to investigate and monitor the landslide of Three Gorges Reservoir Area, the authors obtained the high-precision DEM through the acquisition and processing of the airborne lidar data. On such a basis, the authors made the airborne lidar landslide investigation and dynamic monitoring test qualitatively and quantitatively. The results indicate that the lidar hill shade map can express micro-topography, and the lidar slope and surface roughness maps can provide precise micro-geomorphic feature parameters.
