Geographic Information System

(GIS) A computer system for capturing, storing, checking, integrating, manipulating, analysing and displaying data related to positions on the Earth's surface. Typically, a GIS is used for handling maps of one kind or another. These might be represented as several different layers where each layer holds data about a particular kind of feature (e.g. roads). Each feature is linked to a position on the graphical image of a map.

Layers of data are organised to be studied and to perform statistical analysis (i.e. a layer of customer locations could include fields for Name, Address, Contact, Number, Area). Uses are primarily government related, town planning, local authority and public utility management, environmental, resource management, engineering, business, marketing, and distribution.

(1) (Geographic Information System) An information system that deals with spatial information. Also called "mapping software," it links attributes and characteristics of an area to its geographic location. A GIS is used in a variety of applications, including exploration, demographics, dispatching, tracking and map making. Using satellites and aerial photography, the U.S. Geological Survey and other organizations have developed digital maps of most of the world and continue to update them. Unlike paper maps, digital maps can be combined with layers of information. See digital elevation model and GIS glossary.

(2) (Generalized Information System) An early IBM mainframe query and data manipulation language.
