Check out my post on this here.

It’s in the REST API.

weogeo blogs here about adding GeoRSS support for their listings in both the private Library and the open Market.

This article from Directions Magazine points out that the new version of Geospatial One-Stop — the USGS’s federal government portal for geographic data, services — allows search results to be saved in GeoRSS format ( specifically, RSS 2.0 with GeoRSS simple)

GeoFeeder is an Adobe AIR-based GeoRSS viewer, which is discussed here.

The Canadian Government proposes using GeoRSS for emergency notification in their Architecture for Situational Awareness Systems. The US-centric Environmental Information Exchange Network is also considering GeoRSS to expand their spatial data smarts beyond points.

A couple of months ago, Yahoo! released the beta of their location brokering service, FireEagle. The service just recently came out of private beta and is now open to anyone to store and retrieve their current location.

One feature that was purposefully (so far) left out of FireEagle was getting a location history. Queries only return a unique XML markup of the user’s current location.

EagleFeed is a simple solution to this - it’s sole feature is providing a GeoRSS feed of your FireEagle location.

Since FireEagle allows a user to specify their location accuracy per application - you can choose to just provide a city or neighborhood level response to EagleFeed - making it a nice, variable granularity, location tracker.

Personally, I use it in my blog to provide a small badge on my location. Using SimplePie, a PHP RSS parser, I can easily pull in my location and do caching without having to deal with the complexities of OAuth for just a simple widget.

I’ve never really got into the whole Twittering thing, but I’m sure this will be of interest to some. I just came across GeoTwitter, which is an open source .NET code base that does what you think. Start here with the background details.

In what appears to be the first use of “GeoRSS” in a book title, there is an upcoming book “Practical Google Maps Mashups with Google Mapplets, GeoRSS and KML”. The book won’t be published until this September, and isn’t yet listed on the Apress site, but you can see the Amazon listing here.

While this is the first title that includes “GeoRSS”, searching across Amazon shows 22 results when searching for term “GeoRSS”. Google Book Search shows 90 results. However, it doesn’t appear to have a way to return the number of unique results, so my book shows up twice, and Google Maps Hacks has the English and Japanese versions.

Looking over the categories of books that mention GeoRSS, there is a very good selection. The most prevalent, and obvious, are mashup and programming books. There is a Mac OS X Leopard book, assumedly referring to the included Dashboard widget. There are a number of surprising (and incorrect) results, such as “A Unsocial Socialist”, which is actually an incorrect OCR for “George”.

Joey Tracker is a nice little app for tracking the Tufts University shuttle bus. They’re running a real time tracking system from Ublip, and receiving updates on the location of the bus via GeoRSS, and mapping that with GMaps API. Nice.
