which stereo-photos are of special value. An abandoned enemy tank, standing 
on the battle-field, can be studied in detail and have its measurements taken in 
this way on the stereo-photos. Other kinds of war material taken from the ene- 
my in action, but which, for some reason or another, cannot be transported to 
the rear for examination, can be stereoscopically photographed and afterwards 
measured in a corresponding way. Examples are manifold. 
PHOTOGRAPHIC INTERPRETATION FOR AMPHIBIOUS 
OPERATIONS 
by 
W. B. Cubby and C. G. Coleman. 
Introduction. 
The study of coasts and beaches for military purposes provides a particular 
challenge to the aerial photographic interpreter. While amphibious operations 
have been made in many wars since Caesar invaded Britain, it was not until 
World War II that the 
analysis of coastal are- 
as for military pur- 
poses became a major 
intelligence factor. 
In 1942 it became 
apparent that the am- 
phibious operation was 
going to become one 
of our principal weap- 
ons against the Axis 
powers. It further be- 
came apparent that we 
needed to know a great 
deal about the physical 
characteristics of an aa 
enemy-held coastal area before we could land a modern combat division with 
a reasonable chance for success. Aerial photography was the most important 
single source of such information. 
In a paper prepared in 1948 (1), Coleman listed three reasons why aerial 
photography was especially important as a collecting medium for amphibious 
warfare in World War II: 
*(1) There was a dearth of other sources of detailed information about the 
physical characteristics of specific beaches and coastal areas. Except in resort 
areas, or in the vicinity of cities, coastal areas were lightly populated and in- 
frequently used. There were no ground photographs, few references in geograph- 
ic literature, and meager and often inaccurate representation on the best avai- 
lable maps and charts. It is generally true that, as Williams (2) states, ’both maps 
and charts tend to regard beaches as a kind of “No man’s land” with which 
neither is greatly concerned.’
