Application of 3S technology in forecast system of geological hazards in the Three Gorges Reservoir

摘要：

Based on GIS platform,multi-layer structure is established in forecast system of geological hazards,and it includes prediction of regional hazards,city hazards and single hazard.Real-time monitoring data is obtained by GPS and traditional survey methods.RS provides macroscopic data in large-scale region and GIS analyzes distribution and development regulation of geological hazards by spatial analysis.According to monitoring data and historical hazard records,the system can forecast change trend and failure time of geological hazards by applying integrated models and criterion.Then multi-result is evaluated.The system can adopt integrated 3S technology to achieve some functions of real-time prediction,risk analysis,and information issuance.
