                    Relative Location Representation
                draft-ietf-geopriv-relative-location-06

Abstract

   This document defines an extension to PIDF-LO (RFC4119) 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.
