Abstract
Many different types of geological hazards have seriously hindered sustainable development of society and its economy. It is critical to pay greater attention to effective geological hazard investigations, monitoring, early warning, mitigation, and prevention through advanced technologies of the Internet, Geographic Information Systems (GIS), Global Positioning System (GPS), and Remote Sensing (RS). In this paper, an information system to monitor geological hazards is designed and implemented on the basis of a WEBGIS platform and a large volume of multi-source remotely sensed data; its network structure and architecture are designed and presented. Detail is provided on the key technologies and function modules. Then, a concrete system implementation is introduced using a typical instance, namely, the geological hazard monitoring of the Three Gorges Reservoir Engineering Areas, followed by conclusions and directions for future work. The focus of our work is its provision of a highly efficient means of realtime geological hazard body monitoring. In addition, information WEB publishing, geological hazard assessment and decision-making for a geological department are also important targets.
