  2. An Information System • Remember those overlay “maps” of the human body from grade school?

  3. A Geographic Information System A GIS is similar, layering mapped information in a computer to help us view our world as a system

  4. What is GIS? A Geographic Information System is a collection of tools to build, maintain, and use electronic maps and associated databases

  5. What Does GIS Do? It locates: • Physical infrastructure, like water and sewer pipes

  6. What Does GIS Do? It locates: • Areas, like land use

  7. What Does GIS Do? It locates: • Incidents, like crime statistics

  8. What Does GIS Do? It locates: • Quantities or densities, like disease mortality rates

  9. What Does GIS Do? It identifies:

  10. From Maps to Information More than just maps… In a GIS, the maps have tables of data behind them. This means when you combine different maps you combine data to get the information you need.
