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.
