GIS stands for Geographic Information Systems which is a computerized mapping system that allows for the integration of hardware, software, and data for use in analysis, evaluation and manipulation of geographically referenced information. GIS allows us to use many different layers of geographic information and overlay them in order to view, question, analyze and interpret data based on their spacial relationship to each other. GIS helps in our everyday lives by providing driving directions, helping determine the best routes for delivering packages, or helping to decide where to build new businesses based on market areas.
