Brady over on Radar posted up about GeoRSS, a very simple to use OGC format that extends RSS by adding location data, can now be consumed via Google Maps and the Google maps API – here’s a blurb from Google…

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.

GeoRSS with Google – [via] – Link.

To get your Flickr photos exported as GeoRSS you have to add “&georss=true” at the end of your URL.

And there’s more (from Brady)!
Mymaps Google

Tonight Google launched MyMaps. It adds the ability to create and share maps directly from Google’s site (you can see a map that I created above). These maps will be added to Google geoindex and will be available to search in Google Earth and in Local Search. These maps will be syndicated via KML; support for GeoRSS syndication is coming (not surprising given that GeoRSS can be consumed by these maps).
