THE ROLE OF PHOTOGRAMMETRY IN INTERNATIONAL DEFENSE
Major General George J. Nold,
Deputy Chief of Engineers, U.S.A.
Mr. Chairman:
Delegates:
Ladies and Gentlemen:
In January 1951, in this same building, my Chief, General Pick, addressed
the annual meeting of the American Society of Photogrammetry and spoke on
the importance of its Role in National Defense. His absence from the country
prevents his personal appearance here today to address this larger group. In the
meantime, our common aims and purposes have become more and more inter
national in scope. The North Atlantic Treaty Organization has grown from an
idea to a force of powerful significance. Our defense plans have passed from the
national to the international plane. Consequently, I, myself, am grateful today
for the opportunity afforded me to speak to you delegates here who are most
concerned in this field — you international experts who are supporting the Role
of Photogrammetry in International Defense.
Many of the nations which you represent are partners in a movement to
strengthen the defenses of freedom loving peoples and the lands which they
inhabit. Significant elements in that defense, which embody both military and
civil aspects, are the preparation and maintenance of adequate maps. Your
contributions in the photogrammetric field comprise a vitally important part
of this common defense effort.
A good many of you are already active participants in mapping programs
which have been generally acclaimed as excellent examples of the benefits which
accrue from real international cooperation. I refer to the concerted mapping
effort being sponsored by the governing authortiy of the NATO countries and
to the mapping programs in Latin America which represent joint efforts of the
United States and the countries concerned.
Regarding this former job, as you know, the first requirement was to
make available to the Armed Forces of NATO adequate map stocks for their
use. These maps reflect international cooperation in their bi-lingual marginal
data and in their use of a common military grid and grid reference system. For
the first time in history all of the maps of the NATO contries are now based
on a common geodetic datum arrived at thru adjustment of existing individual
countries’ datums. The second part of this program required the production of
more than 10 thousand different maps for which approximately 90 million
copies were printed thru the combined efforts of the mapping agencies of all
the NATO countries involved. Under phase three, new mapping is being pre
pared by photogrammetric methods to cover areas not previously covered at
the required scale or with the required accuracy.
In the same spririt of cooperation, mapping representatives of the partici
pating countries are engaged in a program to establish a set of international
standards for maps. These standards, which affect all phases of map prepara-
