【摘要】 随着信息技术、计算机技术、空间技术的发展,我们逐渐进入了以数字化为特征的时代,在我们熟悉的物质城市的身边也充满了这种现象。数字化正在渗透到城市规划、建设、管理与服务中,并发挥越来越大的作用,忽视它的存在将失去城市持续发展的技术手段。因此在当前的城市规划设计、管理、编制、审批过程中,确实需要借助三维可视化GIS 等高新技术手段,通过将规划方案直观地展现出来,帮助规划设计与规划管理人员对各种规划设计方案进行辅助设计与方案评审,并为广大群众的积极参与提供信息平台。论文结合国家自然课题《基于GIS/RS技术的城乡空间规划支持系统研究》,对三维可视化GIS在城市规划领域中的应用进行了研究。论文所作的工作主要有:(1)从理论的角度分析并分解了三维可视化GIS,对三维可视化GIS的概念进行限定,从技术上探讨三维可视化GIS; (2)数据是GIS系统的核心问题,数据获取是构建城市规划中三维可视化GIS中重要方面,研究了城市三维可视化GIS的数据源的获取内容和数据获取方法;(3)解决了建立城市规划中的三维可视化GIS中的三维数据的模型的构造和可视化问题,从三维地形和建筑物的的表达方式的选择、寻找合适建模路线、到进行可视化,为建立三维可视化GIS提供了参考依据。(4)研究三维可视化GIS作为城市规划的支持系统的了系统设计;(5) 以北京市大栅栏地区的旧城改造的城市设计和青岛市城市规划管理信息系统为例,对三维可视化GIS在城市规划设计中的应用做出分析。更多还原

【Abstract】 We have gradually entered a new world which character is digitalization,with the development of the information technology. Digitalization gradually infiltrates into our city including the work of city planning,construction,management and services,and also acts a more and more important role as the methods for building a continuable city. At present, visualization in city 3D scene is core technique of Cyber City. Querying and anglicizing information and base on city 3D scene not only provide vision taste for user, make user have geist cognition for city construction, but also make decision-maker, designer and user have more lifelike, impersonal and rational cognition for status in quo of city layout and blueprint of design. So we need these new technologies of 3D-GIS and visualization to aid the city planner and decision maker to make plans and decisions, and to provide the information platform for public participation city planning.In this paper, the technique of 3D Visualization GIS and the application of 3D-GIS in city planning were researched. The main work as the following:(1)How to acquire and deal with 3D data of terrain data, construction data and other data which were needed in 3D city model was reseArched in this part.(2)Building and displaying the 3D city model suited for aiding city planning, and querying and analyzing information from the 3D city model.(3)The methods and application of 3D Visualization GIS in city planning making and managements.(4)Some instances and examples of the application of 3D Visualization GIS in city planning making and managements.更多还原
