GeoServer 1.5.2 Required

GeoRSS support for GeoServer is only present in 1.5.2 and beyond (1.6.0-beta1).

GeoServer supports GeoRSS as an output format allowing you to serve features as an RSS feed.

Quickstart
Google Maps
Yahoo Maps
Microsoft Virtual Earth

QuickStart

If you are using a web browser which can render rss feeds simply visit the url http://localhost:8080/geoserver/wms/reflect?layers=states&format=rss in your browser. This is assuming a local GeoServer instance is running with an out of the box configuration. You should see the following result:

Internet Visible GeoServer Required

Your GeoServer instance must be visible from the internet, IE. localhost will not work.

Google Maps

How to create a Google Maps mashup with a GeoRSS overlay produced by GeoServer.

Obtain a Google Maps API Key from Google.

Create an html file called gmaps.html:

        map.addControl(new GLargeMapControl());
        map.setCenter(new GLatLng(40,-98), 4);

        var geoXml = new GGeoXml("<INSERT GEOSERVER URL HERE>/geoserver/wms/reflect?layers=states&format=rss");
        map.addOverlay(geoXml);

		YEvent.Capture(map,EventsList.onStartGeoRSS, function(eventObj) { doStart(eventObj); });
		YEvent.Capture(map,EventsList.onEndGeoRSS, function(eventObj) { doEnd(eventObj); });

		map.addOverlay(new YGeoRSS('http://<INSERT GEOSERVER URL HERE>/geoserver/wms/reflect?layers=states&format=rss'));

Non Internet Explorer Users

GeoRSS overlays are only supported in Internet Explorer, versions greater then 5.5.

How to create a Microsoft Virtual Earth mashup with a GeoRSS overlay produced by GeoServer.

To access a GeoRSS feed from Microsoft Virtual Earth the file (ve.html) must be accessed from a Web Server, IE. It will not work if run from local disk.

Create an html file called ve.html.

ve.html

<html>
  <head>
    <script src="http://dev.virtualearth.net/mapcontrol/v4/mapcontrol.js"></script>
    <script>
     var map;

     function OnPageLoad()
     {
        map = new VEMap('map');
        map.LoadMap();

        var veLayerSpec = new VELayerSpecification();
        veLayerSpec.Type = VELayerType.GeoRSS;
        veLayerSpec.ID = 'Hazards';
	veLayerSpec.LayerSource = 'http://<INSERT GEOSERVER URL HERE>/geoserver/wms/reflect?layers=states&format=rss';
	veLayerSpec.Method = 'get';
	map.AddLayer(veLayerSpec);
    }
   </script>
 </head>
 <body onload="OnPageLoad();">
    <div id="map" style="position:relative;width:800px;height:600px;"></div>
  </body>

</html>

You must insert your specific maps api key, and geoserver base url
