What is GIS?

Geographic Information systems are important to everyone, from the ubiquitous GPS unit in your hand, to the vastly important field of Emergency Management. We can't avoid the troubles that mother nature gives us, but we can be better prepared. GIS is key to that preparedness.

All maps distort the world in some ways. They make it look flat and tiny, and they take away almost all of the stuff that you see when you look at the real world. Similarly, all representations of data (graphs, tables, charts) distort the things they represent, in order to make it easy to see some mathematical relationship. This page describes some of the decisions we make for displaying data in the maps.

For example, the town zoning map clearly indicates areas of business concentration, but not levels of concentration. Another way to indicate business concentration would be to use color to show one or all of the following variables: Number of Employees, Average Number of Customers (vehicles), for example.
