Google Earth

Excellent program, it's particularly impressive when you zoom right down from space and then tilt it so you can see right across the countryside. I just zoomed right into the Grand Canyon. Also the larger US cities get 3D building representations. Amazing.

Everything listed on the UNESCO World Heritage List has its exact world co-ordinates listed, in exactly the format that Google Earth requires.

A great program where I could find the street where I live!!!
I could see Graceland, a friend´s home in Australia and many other things...
I installed at home and in the job and it is really technology!!

I've had some fun with this recently too. And yes, I too looked for Graceland

What a cool program. Thanks Mel.
