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.
