Not too long ago Google started work on performing a makeover on some software called Keyhole. The result is Google Earth. I have never had a play around with Keyhole, but I made a point of grabbing Google Earth today, grabbing a few screenshots as I had a look around.
You'll have to download Google Earth. The installer is a 10MiB file. However you will still need an Internet connection to use Google Earth as it streams imagery and other data from the web during use.
I fired up Google Earth and was presented with the Earth.
After spinning the world around a bit, I located Britain and zoomed on in.
As I zoomed towards London, Google Earth streamed more detailed pictures of the area onto my computer. So far, you may as well be using the Satellite view in Google Maps.
Now it's time to have some fun. Here's Buckhingham Palace:
Here it is from a different angle!
With Google Earth you can rotate the image and change the angle from which you view the Earth. Add to that the ability to overlay information such as railways, crime rates, road names and more and you have an application with some serious 'cool' to it. Alas, some of the features are quite US-centric, but where the satellite imagery is detailed enough, you can have some serious fun with Google Earth.
I'll let you have a play for yourself now. Let us know if you find anything funky or particularly useful!
