The geological hazard survey has undergone several rounds of development since 1990s, and now it has evolved into a disaster geological survey based on the disaster-formative background investigation and hidden danger identification. Southeast Tibet second-level project is located in southeastern Tibet with the characteristics of inadequate geological work, fragile geological environment and poor working conditions. The project mainly focuses on 3 aspects of the detailed geological data, the law of geological disasters and the evaluation of the disaster-formative background and hidden danger identification. In order to achieve these requirements in the special environment of southeastern Tibet, the field survey data acquisition system, InSAR, 3D laser scanning, UAV aerial survey remote sensing system, simple observation and some other technical methods are applied. The applicability of various survey techniques is also summarized. By summing up experience and finding deficiencies, the reference for future investigation and evaluation in this area can be provided.
