What is GIS?
Geographic Information Systems or GIS is the collection data, which is stored in a database that is then analyzed and used to create a visual representation of the data in the form of a Map Figure 1.

GIS makes extensive use of layers Figure 2. , beginning with a base or, first layer. The base layer is usually a digital map like the maps you may have seen on your car’s GPS or, Web sites like MapQuest Google maps or, a digital photograph taken from either an airplane or a satellite.
Once you have a base layer, Placemarks are added to a new layer. For example, let’s say you wanted to create a map marking the restaurants in your neighborhood. First, you walk around your neighborhood and find the coordinates (longitude and latitude) of each restaurant. Mostly likely using a hand held GPS unit (you may also use a GPS smart phone). Then the coordinates would be entered into a database. Using GIS software you can create a layer containing a small icon

Google Earth Overview
Google Earth is a friendly 3D, Internet-based Geographic Information System (GIS) application. This application was originally developed by the Keyhole Inc. located in Silicon Valley. In 2004, Keyhole Inc. was acquired by Google. Google re-packaged Keyhole’s 3D Virtual globe software and released a new version called “Google Earth” in June, 2005. The concept of the Digital Earth was unveiled to the general public by Google Earth; many researchers or governments agencies started to utilize Google Earth for their GIS works.
A list of some of the basic controls and their functions:
The “Look Joystick” control Figure 3: Use the Look joystick to look around as if you were turning your head. Click an arrow to look in that direction or continue to press down on the mouse button to change your view. After clicking an arrow, move the mouse around on the joystick to change the direction of
