LEARNING FROM AERIALS

 
Historical aerial photographs dramatically document changes in Florida's land use. Between 1937 and 1955, the U.S. Department of Agriculture shot more than 40,000 black and white, 9 x 9 aerial photographs of Florida. They are accompanied by 2,500 photomosaic indexes.

Originally intended to assist farmers determine accurate assessments for 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.

In 2002, the Digital Library Center at the University of Florida received funding from the Florida State Library in the form of a "Library Services and Technology Act Grant" to digitize the 1937-55 flight images.
The project is called From the Air: the photographic record of Florida's lands. Images are accessible to all over the Web at http://www.uflib.ufl.edu/digital/collections/flap/index.htm


SNAP SHOTS IN TIME

Aerial photos show you exactly what a location looked like at a particular point in time. By comparing photos from different years, you can see how land uses have changed, grown, and developed. Print out the same location at different years for side-by-side comparisons, or open two images side-by-side on your computer monitor. Using same scale images, make a transparency from one year and overlay it on an earlier year.  

Once you learn to identify a variety of natural and man-made features, you can easily observe changes that have taken place: new roads develop and expand, bridges are built, houses grow out of forested or agricultural land, new recreation areas are created, and shorelines are dotted with marinas and homes. Images depict community growth along transportation corridors and near valuable natural resources. Bridges spread urbanization to undeveloped areas.

 If you develop additional units with these aerial resources, please share them with others by submitting your units to this site. To add units, please contact: The Digital Library Center, University of Florida Libraries at dlc@mail.uflib.ufl.edu


Independent Learner Units

Short history of aerial photography
Interpreting aerial photography

Classroom Units

Spanish Explorers in the New World (Grades 3-5)
Reading/worksheet combination. This unit includes information on Christopher Columbus and Ponce De Leon's exploration of Florida.
St. Augustine- (Grade 6-8)
This unit discusses the founding of St. Augustine. Students use early maps, readings, and aerials to determine what factors might have been critical in siting Spanish colonies.
Miami (Grade 6-8)
This unit discusses the evolution of Miami from the stone circles of the Tequesta to modern high rises. An introduction to aerial photos shows students how to track city growth.
A Place in Time provides a model of how to use aerial images to determine landscapes over time. Two images of St. Augustine Harbor one from 1942 and the other from 1960 dramatically show the difference in land use. The activity for this unit will ask the student to choose a feature in his/her own county and see how the environs have changed over a period of years.
