中文摘要: 以扬州科技学院扬子津校区为例, 以Google Earth为数据源, 以ArcGIS和天正软件为平台, 针对建筑施工图是否佚失, 分别从两条路径制定数字城市建模方案, 一是利用ArcGIS进行建筑物空间位置控制, 二是在空间控制的基础上或利用ArcGIS建模并在SketchUp软件中对模型进行细化处理, 或是直接将建筑施工图导入GIS平台中, 最终将两类数据在ArcGIS平台加以融合, 从而使三维数字城市建模变得快速, 高效, 极大降低了数字城市建设的成本, 同时还对该成果在城市规划、楼盘营销、数字导航领域中的应用进行了初步探讨.

Abstract:Taking Yangzhou Polytechnic College at Yangzijing as an example, this paper takes Google Earth as the data source, ArcGIS and Tianzheng software as the modeling platform. According to the existence of architectural working drawing, the paper establishes schemes of modeling digital city by two ways: ① controls position of buildings by ArcGIS, then models buildings in ArcGIS or does refining treatment in SketchUp; ② controls position of buildings by ArcGIS, then introduces architectural working drawing into ArcGIS directly. Finally all data will be fused in ArcGIS platform. These two methods make the modeling of digital city rapidly and effectively, and reduce the cost greatly. A preliminary investigation has also been carried out on the application in the field of urban planning, housing marketing and digital navigation.
