Why does GIS matter? 10/24/20122

80% of local government activities estimated to be geographically based a significant portion of state government has a geographical component businesses use GIS for a very wide array of applications military and defense scientific research employs GIS 10/24/20123

Examples of Applied GIS 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 10/24/20124

“Almost everything that happens, happens somewhere. Knowing where and when something happens is critically important.” Longley et al. (2001), Geographic Information Systems and Science, John Wiley & Sons, p.2. 5

10/24/2012 What kinds of people live in the 10 th 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 6

10/24/2012 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. 7

10/24/2012 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? 8

10/24/2012 Spatial queries and reasoning Data (spatial/non-spatial) Visualization How can we solve geographic problems? 9

10/24/2012 GIS supports all the problem solving processes through: Spatial data integration Spatial data analysis (tools) Spatial information/knowledge visualization 10

10/24/2012 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 11
