Design and Implementation of Geological Hazard Forecast System Based on WebGIS

In this paper, by analyzing the geological structure in China and WebGIS technology, we design and implement a geological hazard forecast system based on WebGIS which can help us to reduce damage. The system is a three-tier structure, which is flexible and easily expanded. Distributed modulus is designed in the system, which helps us to integrate various heterogeneous data sources. The core of system is a mathematical model for geological hazard pre-warning. Using mathematical model, WebGIS technology of Google Maps, database technology and network technology, a distributed software system is built up, which integrates the functions of geographic information system and geological hazard forecast system. The experimental results show that the system is effective and useful.
