Managing Big City Information Based on WebVRGIS

Left: Above-ground city; Right: Underground data (i.e. underground pipelines).

 

A 3-D Shenzhen City Web platform based on the Web virtual reality geographical information system is presented. A 3-D global browser is employed to load multiple types of demand data from the city, such as 3-D building model data, residents’ information, and real-time and historical traffic data. Using these data, a 3-D analysis and visualization of the city’s information are conducted on a platform. The amount of information that can be visualized with this platform is very large, and the GIS-based navigational scheme enables great flexibility to access different available data sources. All the presented functions of the platform are extracted from the customers’ practical demand. The system design considers some existing geographic human-computer interaction research results.
