ABSTRACT 
The use of a stored-program computer as part of the AP-C 
Analytical Stereoplotter results in an unusually versatile photogram- 
metric instrument and, in addition, provides a separate computing 
facility. This paper summarizes the characteristics of the AP-C 
computer and describes several possible applications related to 
surveying and mapping. As a part of the AP-C system, the computer 
has already been programmed to determine the elements of interior, 
relative, and absolute orientation; to measure the straight-line distance 
between any two points; to direct the coordinatograph for operation 
as a tape-controlled X-Y plotter; and to perform several other 
auxiliary computing and control functions.
