A geographic information system (GIS) is capable of storing, manipulating, and displaying geographic or special information, including maps of locations or regions around the world. This usage can prove to be very beneficial in many instances; such as, a 911 operator who needs to quickly determine the specific location of a caller with an emergency. In addition, a business may use a GIS to display sales information or product popularity in a particular region of the country. Also, another practical use is through the military whom may need to target a specific enemy. In conjunction with a global positioning system (GPS) this could be a very effective method of identifying enemy positions and equipment in a constantly changing battle situation. One of the most popular GIS's to date is Google Earth. This product, released in 2005, is a highly sophisticated program that superimposes images obtained from satellite imagery, aerial photography, and 3D globe. Some uses for it are directions, viewing areas subject to natural disasters, and explore locations on the Moon and Mars. It comes with many various features including a plane simulator, sky mode, street view, water and ocean, and historical imagery. This program is supported on all browsers, and there is a mobile app for the iPhone as well.
