基于GIS技术的城市地下管线断面图的绘制

摘要

城市地下管线断面图可将地面下各管线的埋深情况和空间位置关系直观地反映出来,在地下管线管理中具有重要作用.本文通过分析管线系统数据结构,计算出断面图绘制所需数据,编程实现地下管线断面图的绘制.通过对作者开发的管线管理系统断面图绘制模块进行测试,最终得到准确直观的管线断面图.%The section maps of urban underground pipelines can reflect the buried depth and spatial position of each pipeline under the ground directly, this map play an important role in underground pipeline management. This paper analyzed the structure of the pipe-line data, calculated the data used to draw the section map. This paper made transect and vertical section comes true with program. By the text of section module of the pipeline management system developed by the author, and finally obtained the accurate and intui-tive transect and vertical section.
