IDOT has a full scale photogrammetric unit, fulfilling the topographic mapping needs of the department. Images are also available for purchase for a nominal fee.
IDOT maintains a film library dating back to its inception. During that time, over 8,000 projects have been flown at various scales and covering various areas throughout the state. In addition, high altitude photographic coverage of nearly the entire state is available from a series of late 1960’s, late 1970’s, 1988, 1993/94 and 1998/99, and 2005 photography. Although the vast majority of this photography is in black and white, there are a limited number of projects which have been flown in color or color infrared.
Coverage area photographic requests require a comprehensive search of the agency's records from 1956 to the present, as well as an actual verification from the requesting entity.
