基于MapInfo的城市地下管网拓扑结构生成方法的研究

Study on MapInfo-based Topological Structure Generation for Urban Underground Pipeline Network

文中对城市地下管网拓扑结构的特点进行了分析 ,并设计了管线拓扑数据文件的结构 ,在分析与设计的基础上 ,对基于 Map Info的管线拓扑数据生成算法进行了研究与开发。并采用了镇江市一条街区的实际管线探测数据模拟运行 ,运行结果证明所设计的管线拓扑数据文件结构合理。

Following an analysis of the characteristics of the topological structure of such kind of pipeline network ,the author presents an introduction to the design of the structure of the related topological data files.With this as the basis,a MapInfo based pipeline network topological data generation algorithm is developed .As evidenced by simulation runs with the data actually measured from a block in Zhenjiang City,the data file developed is rational in structure,and the topological data generation algorithm is reliable and correct in operation.
