MEMORANDUM FOR: Deputy Director, DPD-DD/P
ATTENTION:
SUBJECT: Project "G"
REFERENCE: Memo to rom C/PIC/TISD,
dtd 16 December 1958
1. Statement of the Problem:
To determine the specifications for a visible light photo-
graphic collection system, compatible with the physical vehicular
characteristics, which will produce the highest quality photo-
graphic images possible at the present state of the art.
2. Facts Bearing on the Problem:
Vehicle speed and altitude
Space and weight limitations
Compatibility of existing exploitation equipment
and technique with proposed systems
Desirability to increase metrical potential
Lead-time for production of collection and exploitation
equipment
Simplicity and reliability of operation
Film load
Cost
Investigation of feasibility of incorporation of
recent advances in the increase of image quality.
To date, three manufacturers have submitted proposals for
review. These have been generally aimed at satisfying a list of
basic specifications prepared for the then SA/PD/DCI by PIC/TISD
in December 1958 (Reference).

4. other Factors:
It is recognized by PIC that panoramic (cylindrical section)
photography exposed in a convergent attitude will present exploi-
tation problems. However, it is felt that the advantages gained
will offset the disadvantages. Basically the problem resolves
itself to this:
A. Photo interpretation analysts will not be able to make
simple measurements from contact photos because all photos will
be low obliques at the nadir. The photos will need rectification
for this purpose. on the other hand, scale number tables can be
prepared on the electronic computer to aid the PI in this task.
The electronic rectifier currently under development at Hycon will
be able to handle this, but only on a selected basis as time is a
significant factor.

B. Rectified images of the P&E proposed system, using m film
with Eft image format and max. - lateral obliquity, will be ? at
the max, lateral dimension and can be viewed stereoscopically on
Bausch and Lomb stereo-viewers currently being manufactured for use
with "BU configuration photography.
C. The PIC photographic laboratory, with its present pro-
cessing and duplicating equipment should encounter no serious
problems with the P&E proposed film sizes, as all equipment is
25X1 D designed to accommodate film up to M wide.
D. The Wild stereo-microscopes presently under procurement,
with max. 50x magnification, should enable adequate detailed
exploitation of the high resolution products proposed.
E. Presently available measurement and computation equipment
at PIC can accommodate the formats and resolutions predicted, with
the possible modification of higher magnification eye piece in the
Mann and Nistri comparators.
F. It would appear at this time, from a PIC photographic
analysis and exploitation position, that the ideas proposed are
generally compatible with present and planned exploitation instru-
mentation and technique, with the modification and addition of
only a few items. The man-power for adequate and timely analysis
and reporting will, of course, be contingent upon the input rate
of raw material.

Attachment 1: Mathematical analysis
of stereo-enhancement benefits
achieved by convergent camera
attitudes.
Approved For Release 2000/08/03 : CIA-RDP67BOO511 R0001 00100105-4
G. Attachment 1 represents the results of a mathematical
analysis of height measurement improvements which can be achieved
with a convergent camera system. Summarized, the results show
that a =offset (total convergence) of each camera exposure
will enable Z (height) measurements to almost twice the accuracy
of those obtainable with the present A-2 configuration photography.
This has been a serious limitation in the metrical exploitation of
"T" material.
5. Recommendations:
It is suggested that any attempt at making final recommendations
be postponed until revisions of present proposals have been received.
Items to be added to the Itek revised proposal included under
3a, b, c, & d should be made known to both P&E and FCIC so that they
can also make known their ideas concerning these items.
