Photographs and other images taken from the air and space show landforms, vegetation, resources, and cultural features such as buildings. Images taken at different times can be used to study changes in vegetation, landscape, and built environment.
The Maps Unit of Special Collections at the Richard J. Daley Library has an extensive collection of print aerial photographs of Chicago and the surrounding counties.
