GPSMonitor displays your location by feeding your latitude and longitude to this page. This map will show your location if you have your USB or serial GPS connected, and have an active web connection. With a mobile web connection, you can use google maps and your laptop for geocaching. (Yeah, that's doing it the hard way.)

If this map shows you off in a blank wasteland, please email some of your raw NMEA data to me so I can see why it's doing that on your GPS system.

Here are some other sources of GPS information:
