What is GIS?
GIS = Geographic Information Systems
.. a computer system capable of assembling,storing, manipulating, and displayinggeographically referenced information, i.e.,data identified according to their locations
USGS (1997)
In simpler terms, GIS is a set of computer-based systems for managing geographic datato solve real-world spatial problems.

Common uses of GIS
Visualization
Location - What is at..? -
Condition - Where is it...? -
Trends and patterns -What has changed since..?
Modelling and Simulation
To determines what happens if something ischanged or something occurs such asearthquakes, volcanic eruptions, traffic, flood etc.
