We released a new version of Where's Tim this morning that supports GeoRSS feeds. Use a georss query string with the url of the feed as the query string value like this:
or you can create an xml file that contains information about GeoRSS feeds that looks like this:
<?xml version="1.0" encoding="utf-8" ?>
<feed url="http://timhibbard.com/wherestim/rss_messaging.aspx" />
<feed url="http://platial.com/rss/tag/lawrence" />
and then this url - http://timhibbard.com/wherestim/?georss=http://timhibbard.com/wherestim/georss.xml
will overlay Where's Tim with the location of the people that send me text messages
and places tagged "lawrence" on platial.com
It's not quite perfect yet. I need to add a place where people can directly add GeoRSS feeds and color code the icons for each feed.
The next step is to create an interface that will take a flickr RSS feed and spit out GeoRSS.
