摘要
城市地下管线普查工程分测区作业,管线接边的重要性不言而喻。本文针对接边数据可能存在的诸如属性一致性、多通方向数、埋深高程异常、接边长度超限、排水流向异常、接边重复管段等多方面问题进行了深入的研究,设计了高效实用的接边数据检查工具以快速准确地发现问题,提升地下管线普查工程的生产效率和数据质量。
The survey project of urban underground pipelines and cables is divided by area,as a consequence,it goes without saying that the edge matching for pipelines and cables is of great importance.The paper firstly points out the problems of edge matching data such as attributive consistency,connectedness,height anomaly,length overrun,drainage flow anomalies,and matching repeatability.Based on the research of above edge matching problems,the paper puts forward a comprehensive data checking solution which aims at discovering problems efficiently in the survey project of urban underground pipelines.
