Research on the Application of Various Surveying and Mapping Methods in the Geological Hazard of Tianmen Cave Collapse in Zhangjiajie
This article takes the geological disaster of the collapse of the Tianmen Cave,a National 5A scenic spot,in Zhangjiajie City as a research case,uses different measurement techniques to quickly obtain the multi-angle im-age data of the research area,and constructs the real 3D models of different formats by Context Capture software.At the same time,it uses software such as CloudCompare and Trimble realworks viewer to identify and analyze the hidden risks of geological disasters in the disaster area and extract information,so as to complete the tasks of geologi-cal hazard investigation and assessment,as well as geological hazard exploration in the research area.The application research of various surveying and mapping methods provides a new idea for solving the analysis and identification of high-level and extra-high dangerous rock masses.
