Geographic Information Systems (GIS)

What is GIS?

A Geographic Information System (GIS) is a computer system that allows you to map, model, query, and analyze large quantities of data within a single database according to their location.  GIS gives you the power to create maps, integrate information, visualize scenarios, present powerful ideas, and develop effective solutions.  Geographic or Spatial information can assist in understanding the complex interrelationships of natural resources and human population as they relate to potential or known pollution sources.  It is a powerful tool that is now being used in many areas of research.  Commonly the output is a map but the power of GIS really lies in the information embedded within the map objects.
