NATIONAL REPORT ON UNITED STATES 
by 
G. D. Whitmore. 
The American Society of Photogrammetry, with a membership in 1952 
of some 2700, is probably among the largest of the national societies affiliated 
with the International Society of Photogrammetry. In addition there are 38 
sustaining members, these being mainly commercial organizations who desire 
to contribute toward the support of the Society. This compares with 1700 
individual members and 29 sustaining members in 1948. The measure of the 
strength of the Society lies, however, not in numbers alone, but in how well 
the Society accomplishes its objectives. 
The objectives of the American Society are to advance knowledge in the 
science of photogrammetry; to act as a clearing house for the dissemination 
and exchange of information; to foster a spirit of understanding and coopera 
tion among individuals and organizations; to hold meetings for the presentation 
and discussion of papers; and to publish and distribute books, periodicals, and 
papers related to the uses of photogrammetry. We can perhaps tell how well 
these objectives are being accomplished by the well-known American procedure 
of „taking a look at the record.” 
The record shows that the annual meetings of the American Society of 
Photogrammetry have been marked by ever-increasing attendance, by con 
sistently high quality of the technical papers and discussions, by mounting 
interest and participation in the exhibits, and by numberless benefits derived 
from personal contact among those engaged in the profession. In addition to 
the annual meeting held in Washington, a special regional meeting is held each 
September in another city in another part of the country, the locale changing 
from year to year. 
The record further shows that 12 local sections, representing many diffe 
rent parts of the country, have been chartered. Most of these sections hold 
frequent local meetings and carry on an active local program patterned after 
the program of the national society. 
The journal of the Society, Photogrammetric Engineering, is published five 
times during each calendar year, four issues being devoted mainly to technical 
matters, and one issue being the “y ear book”, devoted mainly to business matters. 
This journal is an outstanding publication in its field and is the only periodical 
published in the United States that is devoted exclusively to photogrammetry 
and associated practices. The number of printed pages in Photogrammetric 
Engineering has increased from 640 in 1948 to 849 in 1951, and may total to 
nearly 1000 pages in 1952. 
Within the last few weeks, the American Society of Photogrammetry has 
had the great pleasure of announcing the publication of the new second edition 
of the Manual of Photogrammetry, to replace the 1944 edition. Anyone who 
inspects this impressive volume, and considers that its authors and editors were 
busy men who contributed their precious spare time to the project, will realize 
that its publication represents a monumental achievement.
