AS/NZS ISO 19148:2021采用ISO 19148:2021，该标准规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（以及可选偏移）。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。

AS/NZS ISO 19148:2021 adopts ISO 19148:2021, which 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.
