Images obtained from aerial photography, satellite imagery, and GIS 3D globe are all combined with the technology created by Keyhole Inc to make Google Earth work. This program was initially created by Keyhole Inc., which was later acquired by Google and rechristened as Google Earth in the year 2005. Google Earth Plus and Google Earth Pro are available with more features. If you have a personal computer which runs on Windows, Mac, or Linux you could use this Google Earth. By using this program you can view the streets, cars, and the houses up to 15 meters of resolution. The degree of resolution depends on the area which you are viewing. Some of the areas would have more resolution and you could view up to 15cm of resolution. Places in Las Vegas, Cambridge, and Nevada have such resolution.
For viewing some countries you can also search for address using Google Earth. You just use the mouse or enter the coordinates to see a location.
