Settlement information management system of Beijing-Shanghai High-Speed Railway based on Google Map Service

The Beijing-Shanghai High-speed Railway is a national major project which has higher standard and stricter requirement. It is necessary to monitor subsidence information dynamically during construction to ensure safety in operation. Internet and Geographic Information System (GIS) have a powerful advantage in spatial information management, analysis, statistics and sharing. This paper discussed the construction procedure and method of Subsidence Information Management System of Beijing-Shanghai High-speed Railway Based on Google Map Service, developed and implemented Subsidence Information Management System. The result indicates that Internet Information Technology can be put into use in construction for management and monitoring.
