基于GIS的城市地下管网纵横断面分析的设计与实现

Underground Pipeline Design by GIS for Urban Areas

对已获取城市地下管网数据后 ,如何进行数据挖掘 ,生成管线纵横断面图进行了详细的研究。设计了管线纵横断面的数据结构 ,断面与管线交点生成算法、交点定位算法以及线性内插算法 ,在城市地下综合管网信息系统上 ,实现了管线纵横断面图的生成 。

This paper deals with how to find data and how to get both longitudinal and lateral section maps after data collection for underground pipe lines in urban area.The calculating methods for intersection and intersection point and the designing of data structure are also presented here.
