Google earth is a great program for searching and viewing the earth. In areas that are high resolution you can zoom in close enough to see people. In the picture above you'll notice that you can even track satellites, the yellow lines above are the tracking the ISS (International space station) and the space shuttle.
  Users can share their findings. After you zoom in on an area you can save it then send the file to someone else. That's what this site is about, I have several interesting findings and all you have to do is click on them to have your Google earth program zoom in on it.
  Start by downloading Google earth here.
  Once you have Google earth installed you can click on the links below. When you click on a link you'll get a pop up window, the best thing to do is choose "open" then Google earth will go to that spot, then you can save it to "My places" and save a file by going to "file" and "save as".
