A geographic information system
(GIS) is a system used to describe and characterize the earth and other
geographies for the purpose of visualizing and analyzing geographically
referenced information.
Many have characterized GIS as
one of the most powerful of all information technologies because it focuses on
integrating knowledge from multiple sources (for example, as layers within a
map) and creates a crosscutting environment for collaboration. In addition, GIS
is attractive to most people who encounter it because it is both intuitive and
cognitive. It combines a powerful visualization environment—using maps to
communicate and visualize—with a strong analytic and modeling framework that is
rooted in the science of geography.
This combination has resulted in
a technology that is science based, trusted, and easily communicated using maps
and other geographic views.
