基于ArcGIS的天然气管道专题地图的制作与应用

Making and Application of ArcGIS-based Thematic Maps for Natural Gas Pipeline

为了辅助长输天然气管道的生产运行管理,基于ArcGIS制作了天然气管道内检测作业指挥专题地图,并将内检测作业流程和内检测器运行轨迹准确地反映在图纸上,便于现场指挥人员统筹了解和科学控制作业进度。应用结果表明:基于ArcGIS的管道专题地图,不仅可以准确表示管道走向和各类特征点的地理分布,而且能够表示目标对象的发展轨迹,为管道生产运行管理提供了有力依据。

In order to assist operation management of long distance natural gas transmission pipeline, the thematic maps for commanding operation in natural gas pipeline internal inspection are drawn based on ArcGIS. The detection process and the inner detector＇s trajectory are accurately reflected on the maps, which is convenient to acquaint and control the internal inspection scientifically. The application shows that the thematic maps based on ArcGIS can not only accurately represent the geographic distribution and all kinds of feature points of the natural gas pipeline, but also reflect development trajectory of the target object, provide a strong basis for production and operation management of the pipeline.
