点线表在燃气管网地理信息系统(GIS)数据录入中的应用

The Application of Point-line Table in GIS Data Entry of Gas Pipeline Network

随着燃气管道规模及复杂程度的显著提升,燃气管网数据采集录入效率已日显低下,传统的基于文件的扫描、配准、矢量化模式越来越不适合燃气公司日益增长的对录入速度和准确性的需求。本文介绍了GIS系统在燃气管网中的应用现状,在此基础上分析讨论了多种录入方式的优缺点,指出燃气管网矢量化及数据入库存在的问题,首次探讨了运用点线表形式录入燃气管网GIS系统的可行性,并提出了改进建议。

This paper introduces the application status of GIS system in gas pipeline With the significant increase of gas pipeline scale and complexity,the ef ficiency of data acquisition and input in gas pipeline network has become increasingly low.The traditional file-based scanning,registration and vectorization mode is more and more unsuitable for the increasing demand for input speed and accuracy of gas companies.On this basis,the advantages and disadvantages of various input methods are analyzed and discussed,and the problems existing in the vectorization and data storage of gas pipeline network are pointed out.The feasibility of using point line table to input gas pipeline GIS system is discussed for the first time,and some suggestions for improvement are put forward.
