Study on the Multiple-Information Demonstration Platform of Digital City

This paper has studied the information release platform of digital city, and proposed a multiple-information collaborative platform of digital city which uses the 3D (3-dimensional) GIS model to demonstrate basic city geographic data, the virtual reality technology to realize internal roaming inside important constructions, and the panorama to demonstrate information of important geographic locations. In this way, we can further increase authenticity, immersion and interactivity of the digital city system.
