What is Google Earth?

Google Earth is the world's most detailed globe and one of the most frequently downloaded programs in the history of the internet. Within minutes you will be zooming in on your hometown and taking visual excursions to our planet's most visited or most remote places.
The images are detailed enough that in most populated areas you can clearly see your house, objects in your yard, and sometimes recognize your car parked along the street. A digital elevation model within Google Earth allows you to view the landscape of many geographic areas in 3D.
Recent Images, Updated Regularly

Most of the images in Google Earth were acquired within the past three years, and Google is continuously updating the image set for different parts of the Earth. Large cities generally have more recent and higher resolution images than sparsely inhabited areas.
A misconception exists among some people that the images displayed in the Google Earth program are live-updated directly from satellites. This is not the case. The images are acquired by satellites, processed by commercial image providers or government agencies, and then updated to the Google Earth image database in batches.
However, Google and its image providers do have the ability to rapidly integrate new images into the program. This is sometimes done in emergency situations - such as when an area has been hit by a natural disaster and new images would be of valuable assistance to the recovery and relief efforts.
A Free Download
Google Earth is a free downloadable program that you install on your Windows, Mac, or Linux desktop or laptop computer. The program requires very little space on your hard drive because the images are stored on Google's servers and streamed to your computer upon demand.
Google Earth is also available as a browser plug-in and as a mobile app. Google has been offering the program for free and improving it regularly since 2005. It has been downloaded over one billion times.
