Orthophotos have been successfully produced from panoramic 
imagery but have not at the time of this writing been evaluated. 
Pan imagery such as NASA's 24 inch lunar panoramic camera 
(Figure 12 and 13) and the 3 inch KA56 (Figure 14, mosaic) have 
been rectified on the OOP. 
Resolution tests were made using high contrast Ronchi 
rulings in a dynamic mode and produced 72 Ip/mm regardless of 
the print speed. Due to limitations of the printer this 
resolution is not presently achievable at magnifications less 
than 2x. 
Conclusions 
The Off-Line Orthophoto Printer represents a development 
that has been conducted in the proper spirit of R&D. Each phase 
of the development concluded in evaluation of the work accomplished 
end the formulation of the next logical effort to carry the program 
to its ultimate objectives. These objectives can be briefly 
summarized as follows - to develop a fast, high resolution, trans 
forming printer capable of operating with digital terrain data 
from a variety of sources in an off-line mode, and capable of 
producing restituted photo products at accuracies that will support 
military mapping and targeting requirements. RADC feels that most 
of these objectives have been met or will be met with additional 
software. 
The Off-Line Orthophoto Printer exhibits a flexiibility of 
operation that is not available in any known instrument. Finally, 
the capability represented by the subject equipment has been achieved 
at a reasonable cost to the Dept, of Defense when compared to other 
comparable R&D programs, and has directly resulted in the non 
military version now available commercially as the OP-C.
