Geospatial tools, which include geographic information systems (GIS), global positioning systems (GPS) and remote sensing, provide us with an understanding of the earth. Through this activity, participants will use GIS tools to identify changes on the earth’s surface. We will examine aerial photography from several different time periods. Based on these data, students will explore, estimate, and measure general changes in land use during these time periods, and will explore impacts to the environment and communities that are associated with these changes.
Dr. John McGee is an associate professor in the Department of Forest Resources and Environmental Conservation at Virginia Tech through the Virginia Geospatial Extension Program. The Virginia Geospatial Extension Program provides workforce development opportunities in GPS, GIS, and remote sensing to support the needs of local governments, state agencies, faculty at 4-year colleges and universities, and pre-college educators. The Geospatial Extension Program directly supports the needs of Virginia Cooperative Extension’s educators and specialists and related programming efforts.
