19 Gainesville Florida Airport through the years -The Gainesville regional airport was constructed in 1935, two years before the first air photos were taken. -In 1979 the new Gainesville Regional Airport opened. Prior to 1979, the runways were unpaved and the terminal did not exist.

20 Change in Motion… Images span in time from 1957 to 1999. Land Cover Change of Gainesville Regional Airport. Land cover changes include Urban, Residential, Forest, and Wetlands. Images were taken from the Map & Imagery Library, University of Florida.
