Natural resources Extension educators use outdoor environmental education sites to increase public knowledge of environmental issues, but locating appropriate sites can be time-consuming. Geographic information system (GIS) software and geospatial data can help Extension professionals choose such sites more efficiently. We describe our use of GIS technology to select a natural resources field day site in Tuskegee National Forest in Alabama. We used site characteristics such as forest type, road access, and slope to narrow potential sites from 94 possibilities to the two best options. Sources of free and low-cost geospatial data also are discussed.
