                           The GeoJSON Format
                        draft-butler-geojson-05

Abstract

   GeoJSON is a geospatial data interchange format based on JavaScript
   Object Notation (JSON).  It defines several types of JSON objects and
   the manner in which they are combined to represent data about
   geographic features, their properties, and their spatial extents.
   This document recommends a single coordinate reference system based
   on WGS 84.  Other coordinate reference systems are not recommended.
