Abstract: The design and implementation of 3-D GIS system for the mass monitoring and prevention of geological hazard is introduced. The system is a project in the program of “Technology of Geological Hazard Monitoring and Prevention”. The work process of field monitoring are analyzed, and the idea of database design is put forward. In association with InfoEarth iTelluro platform and its components’ characteristics, the method of designing the core function module of the system is expounded. Analysis on the system implementation and application result indicates that the system provides help for the development and practice of mass monitoring and prevention information management for geological hazards.

Key words: geological hazard monitoring and prevention, 3D geographic information system, InfoEarth iTelluro, information management
