Compared with traditional geological hazard investigation methods, The unmanned aerial vehicle (UAV) has been widely applied in geomorphology research, Landslide monitoring, and early identification due to its advantages of high flexibility, high security and high efficiency. In this paper, the digital aerial photogrammetry is used to collect the remote sensing data of different landslides, and different processing software is used to generate the result map, then The accuracy and error are compared. The results show that its accuracy can meet the requirements of geological disaster identification such as landslides and ground fissures. The research results provide a certain reference for geological practitioners and provide data support for local geological disaster prevention and control.
