Last month I wrote an introduction to GeoRSS, (GeoRSS: Adding Location Awareness to Web News Feeds). My article was the 30,000-foot view, meant as an introduction to the technology and the value it brings. If you want a more in-depth, geeky view of GeoRSS, I recommend the new article by Adena Schutzberg, Executive Editor at Direction Magazine. "Fun With GeoRSS" really digs in. Here's an excerpt:
Consider what this all means. In time, should things go as I hope they will, anyone, anywhere, could build his or her own instant mashup of just the data needed on whatever basemap and with whatever technology (desktop, Web, etc.) makes sense. Who would put out GeoRSS feeds? Anyone who sees the added value of including location with their data. Consider these ideas: a grocery or specialty store might offer a feed that highlights the different specials in different geographies (thanks to Pierce Eichelberger for that idea), news organizations might tag their news with geographic location(s), government and other organization might offer data from sensors (like the earthquake data or traffic data).
