Webcams Galore has compiled links to over 7000 outdoor webcams around the world. It is possible to view the location of each of the webcams on a Google Map.
To view the Google Map of a webcam just click on the 'Details' link under each listed webcam. The link takes you to a small Google Map displaying the webcam's location.
If you click on the small map a larger Google Map opens which you can then browse to find webcams throughout the world. If you pan the map then the webcams in the current view are dynamically loaded.
