Google has added new National Geographic layers to Google Earth which enables you to explore Africa upclose.
Across Africa, you will see the familiar yellow National Geographic logo. Zoom in to see the title of each feature article or photograph. Click the icon and a pop-up balloon shows a photo and description along with links to the content. Follow those links to read the entire story right where it happened. Not only will you learn about Jane Goodall's Fifi, you'll see her home. Joining the stories and images are layers for National Geographic Sights & Sounds multimedia resources, a live WildCam in Botswana, and a collection of Mike Fay's Megaflyover images.More info over here
The Megaflyover images are stunning. Mike spent more than a year taking 92,000 high resolution photographs of the continent. That project is described in Tracing the Human Footprint, an article in the September 2005 National Geographic. He selected 500 of his favorite scenes of people, animals, geological formations, and signs of human presence and annotated them in Google Earth. Look for the red airplane icons as you fly over Africa. Each of these marks a spot where a high resolution image awaits your own personal voyage.
