Relative Location Representation
Abstract
This document defines an extension to the Presence Information Data
Format Location Object (PIDF-LO) (RFC 4119) for the expression of
location information that is defined relative to a reference point.
The reference point may be expressed as a geodetic or civic location,
and the relative offset may be one of several shapes. An alternative
binary representation is described.
Optionally, a reference to a secondary document (such as a map image)
can be included, along with the relationship of the map coordinate
system to the reference/offset coordinate system, to allow display of
the map with the reference point and the relative offset.
