For a few years now there has been a great National Geographic gallery available in Google Earth. One of the parts of that gallery is the Africa Megaflyover in which you can view herds of animals, natural landscape features, villages, towns, and mining/ drilling operations. If you’ve never explored the National Geographic gallery of layers in Google Earth I highly recommend it.
Applications for Education
The Africa Megaflyover and images of African animals layers in Google Earth could be good layers for students to explore in geography and biology courses.
