Full Description

This document defines the structure and content of a text string implementation of the abstract modelfor coordinate reference systems described in ISO 19111. The string defines frequently needed types ofcoordinate reference systems and coordinate operations in a self-contained form that is easily readableby machines and by humans. The essence is its simplicity; as a consequence there are some constraintsupon the more open content allowed in ISO 19111. To retain simplicity in the well-known text (WKT)description of coordinate reference systems and coordinate operations, the scope of this documentexcludes parameter grouping and pass-through coordinate operations. The text string provides a meansfor humans and machines to correctly and unambiguously interpret and utilise a coordinate referencesystem definition with look-ups or cross references only to define coordinate operation mathematics. AWKT string is not suitable for the storage of definitions of coordinate reference systems or coordinateoperations because it omits metadata about the source of the data and may omit metadata about theapplicability of the information.
