数字校园是采用互联网技术、通讯信息技术、GIS等对整个学校的科学研究、教学工作、日常管理和生活服务有关的所有信息进行全方位的数字化和信息化，从而实现学校信息化、网络化办公的任务目标。三维数字校园更能客观描述和真实展现校园景观，并可实现对空间对象进行三维空间分析的特有功能。 　　　论文按照GIS系统设计思想，进行了数字化校园系统需求分析和总体设计。以西安科技大学临潼校区为试验区，通过Sketchup建模软件建立诸如教学楼、宿舍楼等校园建（构）筑物及树木、花卉等绿化设施的三维模型，并对其进行纹理贴图后，转换为ArcGIS的Multipatch格式。以此三维模型数据为基础，利用ArcEngine组件在Visual Studio 2008 c#.NET编程环境下开发三维数字校园系统。

Digital Campus is the use of Internet technology, communications and information technology, GIS whole school of scientific research, teaching, day-to-day management and life service information on a full range of digital and information technology, in order to achieve the school of information technology, network officethe mission objectives. The three-dimensional digital campus more objectively describe and show the real campus landscape, and the unique features of the three-dimensional spatial analysis of spatial objects. 　　Papers in accordance with the GIS system design ideas, digital campus system requirements analysis and design. Lintong campus of Xi'an University of Science and Technology Experimental Zone, established Sketchup modeling software, such as three-dimensional model of the teaching building, dormitory and other campus building (structure) building materials and trees, flowers and other green features, and its texture mapping, conversion for ArcGIS Multipatch format. This three-dimensional model data based use ArcEngine components in Visual Studio 2008 C #. NET programming environment to develop three-dimensional digital campus system.
