What is GIS?

This tutorial topic provides a definition of Geographic Information Systems (GIS) with links to more in-depth information.

GIS can be thought of as the high-tech equivalent of a conventional paper map. Computer database systems capable of holding and using data describing places on the earth's surface make up a GIS. GIS provides the facility of analyzing things that exist and events that happen on earth.

Definition

A more formal definition taken from the U.S. Census Website summarizes GIS as:

An information system that is designed to work with data referenced by spatial or geographic coordinates. In other words, a GIS is both a database system with specific capabilities for spatially-referenced data, as well as a set of operations for working [analysis] with the data.
(Star and Estes, 1990)
