本文档指定了相对于一维对象的位置的概念模式，作为沿该对象的测量（也可以选择从该对象偏移）。它定义了使用和支持线性引用所需的数据和操作的描述。 本文件适用于交通、公用事业、环境保护、基于位置的服务和其他定义相对于线性对象位置的应用。为了便于阅读，本文中讨论的大多数示例都来自交通领域。

This document specifies a conceptual schema for locations relative to a one-dimensional object as measurement along (and optionally offset from) that object. It defines a description of the data and operations required to use and support linear referencing. This document is applicable to transportation, utilities, environmental protection, location-based services and other applications which define locations relative to linear objects. For ease of reading, most examples discussed in this document come from the transportation domain.
