A geographic information system (GIS) is a computer-based tool for mapping and analyzing things that exist and events that happen on earth. GIS technology integrates, via the Internet, common database operations such as query and statistical analysis with the unique visualization and geographic analysis benefits offered by maps. These abilities distinguish GIS from other information systems and make it valuable to a wide range of public and private enterprises for explaining events, predicting outcomes, and planning strategies. This would be a very tedious and slow process without the speed and efficiency of the Internet. The Internet allows huge global companies to maintain a single database that can be accessed from branches around the world and maintained locally free from manipulation.
The major challenges we face in the world today–overpopulation, pollution, deforestation, and natural disasters have a critical geographic dimension. Whether siting a new business, finding the best soil for growing bananas, or figuring out the best route for an emergency vehicle, local problems also have a geographical component. With the use of the Internet, companies will have the power to create maps, integrate information, visualize scenarios, solve complicated problems, present powerful ideas, and develop effective
