Geographically Encoded Objects for RSS feeds. GeoRSS was designed as a lightweight, community driven way to extend existing feeds with geographic information.
As RSS and Atom become more prevalent as a way to publish and share information, it becomes increasingly important that location is described in an interoperable manner so that applications can request, aggregate, share and map geographically tagged feeds.

Two primary GeoRSS encoding exist, including GeoRSS Geography Markup Language (GML) and GeoRSS Simple. GeoRSS-Simple is a lightweight format that supports basic geometries of point, line, box, polygon. GeoRSS GML is a Open Geospatial Consortium (OGC) GML Application Profile, and supports a greater range of features than GeoRSS Simple.
