1. What is GIS ? A method to visualize, manipulate, analyze, and display spatial data “Smart Maps” linking a database to the map

2. Database “ Not Easy to Interpret”

3. Visualization “Worth a Thousand Words”

4. Two Ways to Input and Visualize Data The World in GIS Raster – Grid –“pixels” –a location and value –Satellite images and aerial photos are already in this format Vector – Linear –Points, lines & polygons –“Features” (house, lake, etc.) –Attributes –size, type, length, etc. Real world

5. Combining Data From Many Sources

6. Data For GIS Applications Digitized and Scanned Maps – –purchased, donated, free (Internet) – –created by user Data Bases – Tables of data GPS – Global Positioning System – –accurate locations Field Sampling of Attributes Remote Sensing & Aerial Photography

7. States Five Data Layers “Alike” Features Roads Capitals Rivers Lakes

8. “Spatial Analysis” – not just a map Turning Data Into Information

9. Asking A Question – Interaction

10. Maps and Database are “Interactive”

11. Multiple Databases can be Linked and Related

12. Some Ways GIS is Used Emergency Services – Fire & Police Environmental – Monitoring & Modeling Business – Site Location, Delivery Systems Industry – Transportation, Communication, Mining, Pipelines, Healthcare Government – Local, State, Federal, Military Education – Research, Teaching Tool, Administration Wherever Spatial Data Analysis is Needed

13. Ecosystem Management

14. 3D Mine with Well Data

15. Environmental Monitoring Toxic Plume

16. Combining Various Display Methods

17. Oil Spill and Contamination

18. Site Location and Client Distance

19. Modeling of Future Trends

20. Clusters and Comparison of Data
