Whooppie!! I’m exploring more and more stuff with Google Earth! If you have not downloaded the latest version 4 beta, please do because theres’s more than just history and geography. I’m simply taken away by the animation and 3D capibilities of this version. Take a look at some videos like the Eiffel Tower or this one as it flies you through NY, Grand Canyon and the Golden Gate Bridge…
But I think the greatest strength of Google Earth is in its sharing capability through the use of kml or kmz files with icons like this 
. I have been addicted to these ge files in communities like Earth Explorer or the GE Blog.
Now i found some really interesting ones
- Lord of the Rings shooting sites,
- the Tour de France routes, Vancouver buildings in 3D, the Seven Wonders of the World,
- 3D models of Giza Pyramid or Eiffel Tower,
- a beautiful yearly time animation of the Earth’s look as seasons change, even a Planet Mars’ overlay landscape and plate techtonic shifting animation since 600 million years!!
…Oh! There are just too many of them. You have to really explore them all by yourself :D
