<p>The above input box allows the input of a URL to a GeoRSS feed. This feed can be local to the HTML page -- for example, entering 'xml/track1.xml' will work by default.</p>
|

<p>The example shows a track, displayed as a line connecting the points of the feed. It also shows markers at positions that have a title tag in the rss item. If clicked, a popup will show title and description.</p>
