Why GIS?
GIS allows you to collect, manipulate, analyze, and display spatial data and information. Spatial data is any data that deals with locations of things.
Just about anything you can imagine has a spatial component to it.
The next few slides will show you some examples of what people have done with a GIS.

Street Class Time (Seconds)
Local Streets 60 seconds
Minor Arterial 120 seconds
Collector 180 seconds
Principal Arterial 400 seconds
With the proper data you can use GIS to determine how far you can walk in a certain amount of time. The green area shows how far a student can walk from Butterfield Elementary school within 15 minutes.
