GeoRSS

GeoRSS es un conjunto de estándares para representar información geográfica mediante el uso de capas y está construido dentro de la familia de estándares RSS.^[1]

En las GeoRSS, el contenido consiste en puntos de interés georreferenciados y otras anotaciones y las fuentes se diseñan para generar mapas.

GeoRSS puede utilizarse como RSS 1.0, 2.0 y Atom, el último estándar IETF.

Ejemplo

Aquí es un ejemplo GeoRSS Simple usando Atom.
