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

I was pleasantly amazed to find out that Apple’s DashCode includes a Project Template for building a “Maps Widget” that handles GeoRSS feeds and KML documents.

If you’re not familiar with them, Apple Mac OS X provides Dashboard Widgets - which are small HTML and Javascript enabled windows that can quickly display information such as sports scores, travel information, stocks, and thousands of other applications. Apple’s recently released update to their operating system, Mac OS 10.5, aka Leopard, includes the final version of DashCode. DashCode is a development environment for building these widgets.

Building a Map Widget is simple: select the project, add a GeoRSS or KML URL, get a GoogleMaps API Key (confusing because Google requests a URL, which isn’t actually used by the widget), Save it and you’re done - near instant Map Widget.

minimap is a Firefox extension that adds a very feature rich geo-sidebar to your Firefox browser (also available as a Flock plugin).

The extension offers incredible integration with online mapping and search services. When you first open the extension, you see a Google Map to which you can add locations or just explore. You can also drag and drop addresses, plain text or Microformats - minimap also offers Operator support - which show up on your map as saved locations. At any of these locations you can get directions, view in other mapping services, find books or services at the location, or general local search Google, Platial, Tagzania, and hopefully more soon via OpenSearch-geo.

The newest release, 0.1.4.7, adds GeoRSS and KML support. You can drag and drop (or use the menus to add) any GeoRSS or KML link and the markers will show up in the sidebar map.

So now you can view your feeds from services like Mapufacture or your Yahoo Pipes mashups within your browser and mix it with content you’re viewing on a site.

Midgard, a very full-featured CMS that is being used to replace Maemo.org has added a lot of functionality for supporting publishing & consuming GeoRSS.

Check out the Midgard’s Position module which uses a very nice PHP geographic position library. Midgard also uses RSSCreator with some geo modifications.

You can see an example of a GeoCMS built using Midgard by checking out the DeathMonkey motor cycle tour site.

The content management system Drupal now has the ability to consume and produce GeoRSS.

Dan Karran released a GeoRSS module that plugs into Drupal. He also developed a plugin that supports KML for use in GoogleEarth. These modules are part of a Geospatial Content Management System (GeoCMS) demonstration system.

This project is very exciting as it is an excellent demonstration of large sites using Content Management Systems the benefits and ease of sharing and producing geospatial information.

Find out more about the plugin, and download it, from the Drupal site.

Adena at AllPoints noted that MapInfo will be supporting GeoRSS. The original article is at GISCafe Weekly.

Once again, no indication of which flavor they will be using. That’s something we still have to sort out.

OpenLayers, the free and open-source dynamic map viewer, now natively supports layering GeoRSS feeds.

Give it a try, an example feed might be the Platial places tagged with snowboards: http://platial.com/rss/tag/snowboard

Version 3 of the Virtual Earth Map Control has been released, with support for GeoRSS. Great news!

Quick data-binding for GeoRSS – Now, you can quickly and simply bind data to pushpins using the standard data format GeoRSS. Just point the control at your GeoRSS file or service and it will automatically manage the process of creating pushpins and pop-ups.

Read more about the release on the Virtual Earth Developer Blog.

The recent news about Community Mapbuilder’s 1.0 release reminded me that way back in January Pat Cappelaere said that Mapbuilder will support GeoRSS “on the client side on the upcoming 1.0 release (both atom and RSS formats).”

Try it out and let us know how it goes.

ROME is an open source (Apache license) set of Atom/RSS Java utilities that make it easy to work in Java with most syndication formats.
