GeoRSS PointTrack in OpenLayers

+

This demo uses OpenLayers.Layer.GeoRSS and OpenLayers.Layer.PointTrack. The track is created by connecting the points of the GeoRSS feed.

+
+ GeoRSS URL: +
+

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.

+

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.
