This example shows you how easily jQuery + jMaps makes adding a Geo feed.
Google GeoXML and KML allows you to add a feed of points to a map.
jQuery(document).ready(function(){
jQuery('#map1').jmap('init', {'mapType':G_HYBRID_MAP,'mapCenter':[55.958639, -3.162516]});
jQuery('.add-feed').click(function(){
jQuery('#map1').jmap('AddFeed', {
'feedUrl':'http://api.flickr.com/services/feeds/geo/?id=84656963@N00&lang=en-us&format=rss_200'
}, function(feed, options){
jQuery('.remove-feed').click(function(){
jQuery('#map1').jmap('RemoveFeed', feed);
})
});
});
});
