Abstract:

The rapid development of large cities requires powerful and efficient tools for the urban planning. In the past, the main method for analysis, design and management of the urban planning was 2D maps. Nowadays, the study on application of virtual 3D city models for surface modeling and urban planning has been focused in many researches. Virtual 3D city models create completely new analyzing and designing opportunities for urban planners. The visualization of design and planning concepts in the 3D context provides for more suitable solutions for urban planners. From the virtual 3D city model, the urban planner will develop scenarios of planning and evaluating options through visual spatial analysis to select the optimal planning option. This paper proposes a process of virtual 3D city models development. The experiment was implemented in Kien Thuy industrial zone, Hai Phong city. The virtual 3D city model of the study areas was developed and some results of virtual 3D city application in urban planning in Kien Thuy district, Hai Phong city also presented
