Definition:
Geographical Information Systems (GIS) are defined as Data Analysis
and Visualization Services that are designed specifically to process and
visualize geographically referenced data in a layered format. Statistical
or mathematical algorithms may or may not be applied to the data within
the service, but would be done so (and the results displayed) in a
graphical manner. EXAMPLES: Idrisi, Arc/Info.
