【摘要】：随着科学技术的发展，，地理信息系统飞速进步，三维建模技术建设也取得了令世人瞩目的成就。在二维地理信息系统的基础上，通过其他技术手段，实现三维模型的建立，这对一个城市的发展起到了积极作用。三维技术的发展已经从单纯的模型建立发展到模型的相关性的应用，在实际应用上提出了更高的要求。本文以重庆交通大学南岸校区为研究对象，将三维建模理论及技术引入GIS系统中，结合目前主流技术与软件，从系统需求与可行性、三维GIS系统模型构建的关键技术、平台功能设计等方面进行分析研究。在skyline平台下，建立校园三维模型的原型，利用Visual Studio2010中C#对校园三维场景系统进行二次开发，实现了重庆交通大学南岸校区三维地理信息系统的构建与开发。该系统除了一般二维地图、二维软件常用的基本地图操作功能之外，还实现了距离面积量测、地形剖面分析和空间分析等功能，让用户在系统中对校园场景进行三维直观的体验。系统的建立对于提高三维城市、数字城市、数字小区的建设具有重要的意义和指导作用。
[Abstract]:With the development of science and technology and the rapid progress of geographic information system (GIS), the construction of 3D modeling technology has made remarkable achievements. On the basis of 2D GIS, the establishment of 3D model is realized by other technical means. This has played a positive role in the development of a city. The development of three-dimensional technology has developed from simple modeling to the application of model correlation, which has put forward higher requirements in practical application. This paper takes the south bank campus of Chongqing Jiaotong University as the research object, introduces the three-dimensional modeling theory and technology into the GIS system, combines the current mainstream technology and software, from the system demand and feasibility, the key technology of the three-dimensional GIS system model construction. Under the skyline platform, the prototype of the campus 3D model is established, and the campus 3D scene system is redeveloped by using C # in Visual Studio2010. The construction and development of 3D GIS in the south bank campus of Chongqing Jiaotong University are realized. In addition to the general two-dimensional map and the basic map operation function commonly used by two-dimensional software, the system also realizes the measurement of distance area. The functions of terrain profile analysis and spatial analysis enable users to experience the campus scene in the system. The establishment of the system is of great significance and guidance to improve the construction of 3D city, digital city and digital community.
