Aerial Photography: Florida
"The University of Florida Map & Digital Imagery Library houses the largest and most complete collection of Florida aerial photographs (~160,000 photos) outside of the National Archives. These photos document the dramatic changes in Florida's land use between 1937 and 1990. Originally intended to assist farmers in accurately assessing their farms and to provide information on crop determination and soil conservation, today these images provide some of the oldest land use/cover information available. They are used extensively in agriculture, conservation, urbanization, recreation, education, hydrology, geology, land use, ecology, geography, and history."
