As an important living place for human beings , city is regarded as a main place for the birth , spread and development of human civilization.With the continuous improvement of “Digital City”, to build three-dimensional (3D) visualization system of the digital city has become a research focus in Geographic Information System (GIS).The 3D visualization platform, as one of the key technologies of Digital Earth , organically combines the virtual display with 3D GIS by using 3D model and visualization technology . The establishment of city virtual 3D visualization can provide a platform for the application of 3D GIS in every walk of life and build various city scenes in omni -directional and intuitive ways , which greatly improves the sharing and using level of city spatial informa-tion.This paperis based on the principles of system development combined with the "Digital City"experiment .Based on the principle of system development, this thesis is meant to give a synthetical research on the overall design of 3D system of the digital city, data process, the manufacture of 3D mode, 3D scene and so on.
