摘要: This study has two major concentrations: 1) exploring methods of creating a digital city model, and 2) applying the model to urban spatial structure, an issue particular interest importance planners. Based on existing studies that primarily address two-dimensional (2D) this paper focuses three-dimensional (3D) structure relating 3D form. Given their greater clarity possibilities for quantitative analysis, both models GIS overlay analysis hold tremendous potential analysing predicting future In project, Xidan Business District in Beijing’s Inner City was area selected implement digital-city application. Under hypothesis is determined by city’s planning scheme current marketing forces, it found actual development does not follow restrictions zoning building height regulations. Some contradictions conflicts, such as location height, appeared studied district. The specific reasons discrepancies need be further studied.
