<h1>GeoRSS PointTrack in OpenLayers</h1>
<p style="font-size:.9em;">This demo uses OpenLayers.Layer.GeoRSS and OpenLayers.Layer.PointTrack. The track is created by connecting the points of the GeoRSS feed.</a></p>
<form onsubmit="return false;">
GeoRSS URL: <input type="text" id="url" size="50" /><input type="submit" onclick="addUrl(); return false;" value="Load Feed" onsubmit="addUrl(); return false;" />
</form>
<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>
<div id="map"></div>
