5. What is a Geographic Information System (GIS)? A computer-based data storage and analysis tool that combines previously unrelated information into a comprehensive picture.

7. GIS gives you the power to do things that were simply impossible before.

8. The power to understand complex relationships. Forsyth County: Water Supplies & Water Delivery System

9. The power to plan for tomorrow, based on an accurate picture of today.

10. The power to present data in a clear, compelling way.

11. The power to make informed decisions.

12. The power to save time, money and even lives.

13. GIS can be applied to: Crime reduction Public safety enhancement Siting new schools Redistricting Floodplain mapping Growth management Disaster recovery Tax mapping Crime reduction Public safety enhancement Siting new schools Redistricting Floodplain mapping Growth management Disaster recovery Tax mapping Economic development School bus routing Fire station location Land conservation Environmental impact studies Water & sewer expansion Superfund cleanup Economic development School bus routing Fire station location Land conservation Environmental impact studies Water & sewer expansion Superfund cleanup

14. Situation #1: The City of Wilson needed to locate a new fire station.

15. Wilson, N.C. drive all the roads in the city figure times and distances to each household and business by hand allow a year to complete the study drive all the roads in the city figure times and distances to each household and business by hand allow a year to complete the study Without GIS:

16. Wilson, N.C. With GIS: ran more than 40 computer scenarios in just 3 days analyzed benefits of building a new station versus moving an existing one determined best solution: relocate 2 existing stations With GIS: ran more than 40 computer scenarios in just 3 days analyzed benefits of building a new station versus moving an existing one determined best solution: relocate 2 existing stations

17. Wilson, N.C. Results: reduced time to reach all locations in city from 7 minutes to 4 minutes over 5 years, city saved an estimated $2,000,000 in building costs, equipment, salaries, etc. Results: reduced time to reach all locations in city from 7 minutes to 4 minutes over 5 years, city saved an estimated $2,000,000 in building costs, equipment, salaries, etc.
