Scope

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.

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.
