Presentation Transcript

  1. Guest Presentation for UST 610 (Fall 2012) Geographic Information Systems/Science (GIS) Sung-Gheel (Gil) Jang, PhD (s.jang75@csuohio.edu)

  2. A GIS Journey National Geographic Video (by ESRI): 10 min. URL: http://video.esri.com/watch/968/a-gis-journey

  3. Why does GIS matter?

  4. 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

  5. Urban Planning, Management & Policy Zoning, subdivision planning Land acquisition Economic development Code enforcement Housing renovation programs Emergency response Crime analysis Tax assessment Environmental Sciences Monitoring environmental risk Modeling stormwater runoff Management of watersheds, floodplains, wetlands, forests, aquifers Environmental Impact Analysis Hazardous or toxic facility siting Groundwater modeling and contamination tracking Political Science Redistricting Analysis of election results Predictive modeling Civil Engineering/Utility Locating underground facilities Designing alignment for freeways, transit Coordination of infrastructure maintenance Business Demographic Analysis Market Penetration/ Share Analysis Site Selection Education Administration Attendance Area Maintenance Enrollment Projections School Bus Routing Real Estate Neighborhood land prices Traffic Impact Analysis Determination of Highest and Best Use Health Care Epidemiology Needs Analysis Service Inventory Examples of Applied GIS

  6. “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.

  7. 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

  8. 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.

  9. 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?

  10. How can we solve geographic problems? Data (spatial/non-spatial) Spatial queries and reasoning Visualization

  11. GIS supports all the problem solving processes through: • Spatial data integration • Spatial data analysis (tools) • Spatial information/knowledge visualization

  12. 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
