I found this short article, "Explore Machu Picchu in Google Maps and the Google Cultural Institute,"from Richard Byrne about Google Maps and more specifically Google Street View. If you go to Google Street View you will find 360 degree views of locations from around the World. If you have not looked at this, it will amaze you. There are image collections from over 65 countries including Loch Ness, Northern Lights in Finland, Taj Mahal and even under the oceans of the World. It is a phenomenal collection and paired with Google Maps a powerful resource to teach Geography.
