SUBJECT: Definition of and
" Study
on Photo interpreter Performance."
1. Because of the pressing need, on both NPIC's and DD/S&T's
parts, for objective information on P. I. performance as a function
of ground resolutions of present and projected reconnaissance
systems, it was decided that an accelerated effort would be advisable.;
This will be somewhat of a condensed version of the full two-year
study which will be continued and will build upon these first results.
Although e hasis will be placed on the lower end of the scale of
resolutionsi in the immediate effort, it will be part
of the work which leads directly into the larger range of resolutions
(up to 15'). Due date for the immediate results is 15 October 1964,
and broader findings from the accelerated effort are programmed for
availability before the end of the calendar year. An experimental design
similar to that followed in the pilot work will be used.
2. All work currently in preparation is directed toward use of
monoscopic materials, due to the press of time. However, similar
investigations using stereoscopic photography will follow immediately.

4. Two A-2 cameras with 9" x 18" at and 24" focal length
will be used for a scale of 1;6000 witYground resolution. Duplicate
(vertical) coverage will be obtained with S0130 film used at 1/150th
sec. and f.ll in one camera and*8402 at 1/200th sec. and f.16 in the
other.
5. A special resolution target of design will
be displayed for the overflights; ground photography will also be

6. The schedule for this study is tightly arranged. Consequently,
only 20 (8" x 8") GEMS simulating approximately 40X enlargements of
photos taken at high altitudes (scale of 1:80,000), with a range of
resolutions, will be produced for this phase. Each GEM, however; will
contain 20 or more items to interpret.
7. Considerable effort has gone into the photo-example collection
phase of this project. Every attempt will be made to have this
continue in order that a significant lag will not occur between the
monoscopic work and the planned stereoscopic experiments.
8. Because of the high resolution, test questions will be
concerned with the smaller details of a target and will not involve
gross recognition of the 1V-raer site Questions will be patterned
on those posed in document (27 July 1964) which required
P. I.'s to subjectively rate ground. resolutions in relation to specific
visual details and intelligence information which those resolutions
allow them to interpret.
