Microsoft, Google and Yahoo support GeoRSS

This week, Microsoft announced their new Live Maps, in addition to supporting Firefox on Windows for 3D, now supports the GeoRSS standard. They join Google which recently announced the support of GeoRSS and KML mapping in their Google Maps API. In short, GeoRSS is a standard supported by the Open Geospatial Consortium that incorporates geolocation in an interoperable manner to RSS feeds. The applications are numerous. With Yahoo!'s support of GeoRSS, all the major players are in and the future looks bright for this emerging standard. As for KML, Google Earth's file format, this new Google Maps integration is not unrelated to the recent announcement of internet-wide KML search capabilities within Google Earth. From the GeoRSS website: 'As RSS becomes more and 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. To avoid the fragmentation of language that has occurred in RSS and other Web information encoding efforts.

KML and GeoRSS Support Added to the Google Maps API
One of the things I love most about Google Maps and Google Earth is that it's easy for anyone to create and display new geographically referenced content. Whether it's pictures from your vacation, favorite places on the globe, or the hiking trails you like to visit, all you have
to do is create a KML file (using Google Earth or any other tool) and load it up. This idea that you can view data from external sources inside Google Maps and Earth is really exciting to us, and I'm pleased to announce two major new features in this area.
To start we now support GeoRSS as a data format for geographic content in Google Maps. We want to enable users to create data in whatever format is most convenient for them, and feel that by supporting both KML and GeoRSS we can enable a wider variety of people and applications to contribute content to Google Maps. We've built support for the Simple, GML, and W3C Geo encodings of GeoRSS -- all you have to do is enter the full URL of a GeoRSS file into the Maps query box to load the file. For example, take a look at SlashGeo's GeoRSS on Google Maps.
Most importantly, we've extended support for displaying geographic data -- both KML and GeoRSS -- into the Google Maps API. Now in addition to programatically adding content to a Maps API site, you can create your content as KML or GeoRSS and load it into the Map with a simple function call. This means that the more than 1 million KML files that are available from all over the web can easily be mashed up with the map on your site. For example, you can add some vacation photos from Japan with the following code:
var gx = new GGeoXml("http://kml.lover.googlepages.com/my-vacation-photos.kml");
map.addOverlay(gx);

This makes it easier for API sites to maintain content in a flexible format that can be accessed via the API or in
a number of other tools directly, and makes it simpler to create a rich API site with declarative content, instead
of a lot of code.
Below is an example that shows KML and GeoRSS layers rendered on a Google Maps API powered map. You can toggle on and off the sample layers, or feel free to enter a URL to your favorite KML or GeoRSS content and hit the 'Add' button to see it on the map.

So when the European Commission created a new software program to predict tsunamis, the agency established a link to a frequently updated earthquake report from the U.S. Geological Survey (USGS).
The USGS feed of quake data uses an emerging technique known as GeoRSS—a computer standard that attaches geographic coordinates to photos, text, and other digital information.
GeoRSS allows the tsunami program to automatically ingest new data—including the exact location of a given quake's epicenter—without human intervention, according to Mikel Maron, a computer programmer who participated in developing the project.
Although still very new, GeoRSS has the potential to become the "quickest way to tag some information with geography," predicted Raj Singh, one the developers of GeoRSS.
Singh, a staff member at the nonprofit Open Geospatial Consortium, says that the GeoRSS service will extend the capability to create such location-based tags—a concept known as georeferencing—to anyone with an Internet connection.
"For GeoRSS, we came to it more from the point of view that everybody's got information that works well for them, and [they] just might have a small need to add a little geography to it", Singh said.
