You could get the IP address of the feed's HTTP server, and then use geolocation library of service to get an approximate location of this IP address.

Here is a free database which can be used with many programming environments: http://www.maxmind.com/app/city

it will return you the approximate latitude and longitude. This will be very rough. It will give you the location of the server which is serving the feed.

You can use these coordinates to display a google map.
