基于Google Earth与Sketch Up的校园三维地理信息系统的建立

Establishment of Campus 3D GIS Based on Google Earth and Sketch Up

以某学校为例,研究基于Google Earth与Sketch Up的校园三维地理信息系统的建立方法与过程,选用Sketch Up来实现校园的精确三维建模,将建好的校园三维模型上传到Google Earth平台上,实现数据共享与三维可视化操作,通过Arc GIS平台,实现三维空间分析功能,完成了三维地理信息系统的建立。此系统具有较强的查询和空间分析功能,比传统的二维校园图更加直观、逼真,进一步提高了校园管理与教学水平。

The paper takes a school as an example to study the method and process of building a campus 3D GIS based on Google Earth and Sketch Up.Sketch Up is used to realize the accurate 3D modeling of the campus.Established campus 3D model is uploaded to Google Earth platform to realize the data sharing and 3D visualization,and realize the 3D function through the Arc GIS platform.Finally,the establishment of 3D geographic information system is completed.The system has strong query and spatial analysis functions.Compared with traditional two-dimension campus graph,it is more intuitive and vivid,and it further improves the management and teaching level of the campus.
