No matter how large or small your community, planners, environmental scientists, public health officers, and other local analysts must deal with spatial information: addresses, land parcels and land cover, zoning, transportation networks, housing stock, neighborhoods, streams, and natural hazards. Federal, regional, state, county, and local planning agencies and private enterprises have realized the power of Geographic Information System (GIS) to identify problems, respond to them efficiently, and share the results with a variety of audience. GIS techniques provide tools to help you present and analyze spatial information.  Prerequisite: GEOG 370 or 491.
