3, Perform an educational function by: 
a, Promoting the wise use of aerial photographs as 
teaching aids and as research tools. 
b. Promoting research programs related to the use of 
aerial photography. (The committee should strive to 
maintain a list of research projects which will add 
to the general and specific knowledge in this area, 
and which students and staff members might logically 
undertake.) 
The need for small amounts of aerial photography taken of specific 
targets, on fairly specific dates, and under specific circumstances seemed 
to dictate that the University own and operate its own photographic aircraft. 
Investigation of this possibility showed that the University Institute of 
Aviation already owned a North American AT-6 aircraft (U. S, Navy designa- 
tion - SNJ) configured for vertical aerial photography. The investigation 
also located two F=56 aerial cameras. Acquisition of a camera mount suitable 
for installing the F-56 camera in the AT=6 aircraft permitted an exploratory 
trial of the equipment. Results of the trials were favorable. 
Since the Institute of Aviation maintains several salaried pilots in 
operating an internal air-charter service to facilitate University activities, 
and since the AT-6 aircraft was being maintained as required for licensing by 
the Civil Aeronautics Administration, stand-by costs normally associated with 
commercial aerial photography were largely eliminated. Acquisition of roll 
film processing equipment for the University Photographic Laboratory was 
accomplished at nominal cost and a surplus, military K-17B camera was. pur- 
chased to provide a negative format for teaching purposes which was similar 
to most commercial aerial photography and to permit greater flexibility in 
focal length and altitude combinations. Recent acquisition of a Saltzman 
aerial enlarger (Model 30WAA), Zeiss auto-focus rectifiers (Models SEG-II and 
SEG-IV), and a second order stereoplotter (Nistri Photocartograph V) have 
further increased the capabilities of the University. 
As the Committee on Aerial Photography. filled requests for aerial photo- 
graphs originated by University departments, a significant accumulation of 
aerial negatives developed. The potential usefulness of these negatives to 
other colleges and universities, particularly in Illinois, was recognized 
from the outset. This, and the gradual accumulation of negatives from other 
agencies on a loan basis, led directly to the establishment and announcement 
of the University of Illinois Air Photo Repository. 
Each agency depositing negatives in the repository is assigned a code 
symbol consisting of two letters. Rolls of negatives deposited are given a 
repository serial number consisting of the two-letter code of the depositing 
agency and a three-digit roll number. Negatives are cross-referenced by 
location of photography and, to some extent, by specific features of interest. 
Photography in the repository on June 1, 1960, ranged in scale from 1:1,500 
to 1:52,500 and included some coverage of 10 states in the United States, the 
District of Columbia, and one unidentified island in the South Pacific Ocean.
