In 2005, Ningbo Design Research Institute of Mapping & Surveying started the development of concepts and an implementation of Virtual Reality Ningbo System (VRNS). VRNS is being developed under the digital city technological framework and well supported by computing advances, space technologies, and commercial innovations. It has become the best solution for integrating, managing, presenting, and distributing complex city information. VRNS is not only a 3D-GIS launch project but also a technology innovation. The traditional domain of surveying and mapping has changed greatly in Ningbo. Geo-information systems are developing towards a more reality-, three dimension- and Service-Oriented Architecture-based system. The VRNS uses technology such as 3D modeling, user interface design, view scene modeling, real-time rendering and interactive roaming under a virtual environment. Two applications of VRNS already being used are for city planning and high-rise buildings' security management. The final purpose is to develop VRNS into a powerful public information platform, and to achieve that heterogeneous city information resources share this one single platform.
