线性参考在油气管道选定线中的应用研究
|
摘要
线性参考是针对线性要素进行显示和分析的一种重要模型,它可以解决线性要素动态显示及分析问题。利用油气管道选定线平台中使用里程属性来替代传统X,Y坐标描述位置的方法,解决桩与管道选定线空间位置、野外踏勘的标识及分析问题。
Based on the display and analysis of linear elements,linear referencing is a method of spatial referencing that can solve the problem of dynamic display and analysis using linear elements. This article discusses how this method of expressing location,in which the locations of features are described in terms of measurement along a linear element instead of pairs of coordinates,is put into use in the route selection of oil and gas transmission pipelines,and how it helps to locate the spatial position of stakes and pipelines as well as marks in the process of geographical survey.
