On 17 December 1964 a report, prepared by DNB, PS9 and All entitled "Aircraft
huage a Function of Photographic Ground Resolution" was submitted
to J'WC. An oral presentation. of this research was also given on that date.
As a result of (1) ; the work described in the above mentioned report; (2) a
arm from FS to JWC requesting guidance in determining the factors (affecting
PI performance) to be studied in 1965; and () the requirement to determine by
mid-?4arch 1965 the optimum stereo convergence throughout the range of practical
obliquity angles, discussions hold on 17 December 1964 and a conference on 9
January 1965 were directed at determining the goals of research of the immediate
future. It was concluded that
1. Attempts should be made to ane er the stereo/obliquity
angle question by mid-March 1965, and
2. That FS9 DNB and AR should prepare a statement of the
first research to be performed on a long-range basis for
review by JWC, after which such a research program
should begin.
Consequently, discussions on various procedures for answering the stereo/obliquity
angle question resulted in a decision, made on 13 January 1965 by DNB, M. BJp.
RdC and P'S, to request 0 to make photographs of their terrain model and to .~-
ask Pie to make pair-csmrparieons (or judts by other similar methods) of the
photographs. On 19 January 65 M, FF and RdC visited =and made arr'sugesnents STAT
to obtain the following photographs:
Using a camera with a 90mu F.L. lens with type 4401 film at
55 feet above the 87:1 scale model, photographs will be made
with these stereo convergence angles at each of these obliquities:
Each combination at each
of 4 sun azimuths and
camera position relative
to the model at 600
sun elevation

Present plans are to use photographs made at one sun as.im nth and camera position.
Photographs with other am azimuths and camera positions are being made to give
a selection of asimuth/position combination and to enable use of more exam one
ez,th/position combination if necessary. Pretesting will begin bete the
5th and 15th of February and the final testing will begin on or shortly after
15 February. With this schedule it appears feasible to complete this project
by mid-March.

Discussions on the gals of the first part of the long-range research effort have
been held and during the first half of February, AR and FS will formulate initial
plans after which DNB, FS and AH will establish goals in a final form for eview
by JWC. Yntentione are to begin work on the long-range program just prior or
in+mediatcely after completion of the present stereo/obliquity angle program to
achieve continuity of effort.
