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 .

关 键 词：线性参考 动态分段 路径
