What is GIS?
A Geographic Information System (GIS) that uses computers and software to explore the fundamental principle of geography, as location is important in people’s lives. GIS is used to inventory, analyze, manage and display all forms of geographic information as it relates to many locations in the world. For example, if you drive down a highway, more than likely, a GIS system was used to manage the signs along the route. Or if you look at a map on the internet, more than likely, a GIS system was used to make the map.
A GIS system takes numbers and words from databases and puts them on a map. Most of the information is tied to a location, and a map shows patterns in the data that might not have otherwise been apparent. Putting data on a map helps you ask questions like: Where, Why and How, based on locational information. With geographical knowledge users can make better decisions. With the vast sources of information available today, GIS is a key tool in determining what it all means.
The field of GIS has advanced rapidly in recent years, with the availability of rapidly increasing computer power, development of software, and the proliferation of inexpensive GPS devices. GIS provides location based solutions today, for Government and Industries around the world.
