What is GIS?
Geographic Information Systems
“In the strictest sense, a GIS is a computer system capable of assembling,
    storing, manipulating, and displaying geographically referenced
    information…” --USGS

   About 80% of all data have a spatial component.

   GIS promotes a better understanding of the world around us and
    allows us to make more informed decisions.

   GIS is more than just data and maps.
    GIS is…
    “an organized collection of computer hardware, software, data, and
    personnel designed to efficiently capture, store, update, manipulate,
    analyze, and display all forms of geographically referenced
    information.” --ESRI

   What is this “ArcGIS”?

The keyword is
 scalability.

Layers are the key
     A bit about data

 Layers can be features or
   surfaces
                                       Polygons




                             Lines



                                     Points
Raster
