Resumen de Geographical Information Systems (GIS) Mapping of Environmental Samples across College Campuses.

In this laboratory experiment, students take environmental samples at various locations around the college campuses, take geospatial coordinates with a global position systems (GPS) unit, and map their results on a geo-referenced campus map with geographical information systems (GIS) software. Nitrogen dioxide air pollution sampling is used as an example, although other environmental studies could be mapped as well. In addition, students compare their results to those observed by governmental agencies, such as the Environmental Protection Agency. By studying spatial differences in pollutant concentrations, both indoors and out, and comparing their data to that observed by governmental agencies, students can begin to understand variability and the geospatial relationships in environmental sampling.
