A GIS Journey National Geographic Video (by ESRI): 10 min. URL: http://video.esri.com/watch/968/a-gis-journey
80% of local government activities estimated to be geographically based • a significant portion of state government has a geographical component • businessesuse GIS for a very wide array of applications • military and defense • scientific research employs GIS

“Almost everything that happens, happens somewhere. Knowing whereand when something happens is critically important.” Longley et al. (2001), Geographic Information Systems and Science, John Wiley & Sons, p.2.
What kinds of people live in the 10th Congressional District? Where should I open my next clothing outlet store? Where should I dig up the road to gain access to the gas main? How can my authority best respond to the needs of those single parent families with low income and poor housing? How can I find a famous Italian restaurant in this city and which route would be the fastest way? Geographic (Geospatial) Problems
Maps and GIS Mapping does not always mean doing GIS! However, a map can be transformed to either spatial information or spatial knowledge depending on how you use GIS.
Geographic Problems • Location…Where is it? • Where are my competitors? • Proximity…What is near? • How much disposable income is within ¼ mile? • Patterns…How is it distributed? • Public facilities, population (age specific), land use… • Modeling…What if…? • A competitor closed • Local and major employer closed?
How can we solve geographic problems? Data (spatial/non-spatial) Spatial queries and reasoning Visualization
GIS supports all the problem solving processes through: • Spatial data integration • Spatial data analysis (tools) • Spatial information/knowledge visualization
The Power of GIS: Data Integration • Link basemap with: • Residential data • Agency data • Scanned documents, images or videos • Global positioning system data • Backdrop with: • Digital aerial imagery or • Satellite imagery
