Research and Application of Beijing Earthquake Disaster Prevention System Based on GIS

With the development of spatial information technology and computer technology, GIS technology is widely used in the field of earthquake research. In this paper, the research and application of the GIS-based earthquake disaster prevention system of Beijing is discussed. A four-level system architecture design is presented. The key technology and research results are introduced, including multi-source data integration management, data query and spatial analysis, and user authorization management. A lot of operating interfaces and results are illustrated. Based on the GIS platform and web portal, the system realizes data integration management and efficient service. The system has been deployed and applied in practical work. The actual application results show that the research results have important application significance.
