ISO 19148:2012规定了相对于一维对象的位置的概念模式，作为该对象的（并可选地偏移）的度量。它定义了使用和支持线性引用所需的数据和操作的描述。 ISO 19148:2012适用于定义相对于线性对象的位置的运输，公用事业，位置服务和其他应用

ISO 19148:2012 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. ISO 19148:2012 is applicable to transportation, utilities, location-based services and other applications which define locations relative to linear objects.
