二维地图与三维可视化一体化存储研究

Integrated storage of 2D maps and 3D visualization

以某城市部分地下管网为主要表达载体,在VS2010.NET环境下集成地下管线信息系统,使用Arc GIS10.0对二维空间数据进行处理,利用Skyline所带组件结合影像图完成三维地形建模MPT文件的制作,将二维管线专题数据通过编程完成到三维数据的转换,最后再使用Arc GIS Engine与Terra Explorer API所带有的二次开发接口完成二三维匹配及一体化操作,使系统达到能集合二维的基本分析功能和优秀的三维观察能力,完成二三维一体化建设这一目的。

This study is based on part of the underground pipeline network of a certain city. In the VS2010. NET environment,we integrated the underground pipeline information system and processed the 2D spatial data by using Arc GIS10. 0. Using Skyline components with shadowgraph,we completed the 3D terrain modeling MPT file,and transformed the 2D pipeline thematic data into 3D data. Finally,we used the secondary development interface of Arc GIS Engine and Terra Explorer API to complete the match of 2D and 3D,as well as the integration operations. The system can realize the basic analysis functions of 2D and excellent 3D observation,and has achieved the goal of integrating 2D and 3D.
