Abstract:
The technologies of remote sensing(RS), geographic information system(GIS), and Beidou navigation satellite system(BDS) are used to achieve a comprehensive multi-method, multi-level, and multi-scale survey, among which RS is for early identification of hidden geological hazards, BDS for ground validation, while GIS for organization of survey results and comprehensive information prediction analysis and risk assessment of geological hazards. Through investigation, the geological hazard risks and hidden dangers in Dongning City are identified and mapped out, as well as scientific risk assessment of geological hazards. The results provide objective, real-time, and dynamic geological hazard data to support emergency management and disaster prevention efforts in the study area.
