A Uniform Resource Identifier for Geographic Locations ('geo' URI)
Abstract
This document specifies a Uniform Resource Identifier (URI) for
geographic locations using the 'geo' scheme name. A 'geo' URI
identifies a physical location in a two- or three-dimensional
coordinate reference system in a compact, simple, human-readable, and
protocol-independent way. The default coordinate reference system
used is the World Geodetic System 1984 (WGS-84).
