| 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

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.
