What is GIS?

GIS stands for Geographic Information Systems.

This system is not just a set of software and hardware, but includes you, the user.

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.


3

It all starts with DATA!

Normally when you think of data you think of

something like this chart.

GIS let’s you turn this table showing the

population of counties:

Into a Map:

Now you can see WHERE the population is.

1999 population

Using data regarding past natural disasters, you may create a map showing high risk areas.

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.

Now you are ready to begin

The remaining chapters will guide you through the process of making a map of your school.

Good luck and have fun!
