National Report on the United States*
Te American Society of Photogrammetry
continued to pursue aggressively its ob-
jective of advancing knowledge and applica-
tion of the science of photogrammetry Dur-
ing the past four years progress has been made
both in increasing membership and expan-
sion of the scope of interest and application.
In general, membership expanded at a rate of
approximately 15 per cent, reaching the pres-
ent total of over 3,400 corporate members, 80
sustaining members, and 350 student mem-
bers.
Major advancements in scientific knowl-
edge and accomplishment included but are
not confined to the following:
a. The development of electronic printers
and photographic rectifiers.
b. The development of new theories, labo-
ratory models, and working instruments
for semi-automatic and automatic pho-
togrammetric mapping.
c. Application of electronic computers in
analytical triangulation.
d. Photogrammetric applications of radar
photography.
e. Advanced applications of the orthopho-
toscopic principle.
f. Improved lenses and cameras for wider
coverage and at higher altitudes. These
cameras include longer focal-length,
convergent and panoramic types.
g. The use of airborne profile recorders and
stabilization devices for aerial sensors.
À large contribution was made to the ex-
tensive highway program in the United States
in the form of producing specifications for the
application of photogrammetry to highway
planning and construction, and the develop-
ment of combination stereoplotting machines
and electronic computers for expediting oper-
ations.

The art of photogrammetry was also ap-
plied in research and testing of missiles and
rocketry, medicine, satellite studies, as well as
more extended use in forestry, and stockpile
inventories of various materials.
During 1956 the headquarters of the Soci-
ety was moved into its space in a new science
building. This location has proven adequate
for directing the operations of the Society;
however, due to the continuing growth of the
collection of scientific materials pertinent to
photogrammetry, it has been necessary to use
additional storage space.
The Society Journal, “PHOTOGRAMMETRIC
ENGINEERING”, issued five times per year, has
continued to grow both in quantity and qual-
ity of content and in popularity. In addition
to delivery of the Journal each year to Mem-
bers, there are over 1,000 outside subscribers.
There is also a marked increase in the orders
for back numbers of the Journal for libraries
of commercial concerns, indicating the in-
creased interest in photogrammetry by in-
dustry.
The second edition of the PHOTOGRAM-
METRY MANUAL which was published several
years ago continues to be quite popular with a
sales record over this period of approximately
2,800, bringing the total sales of this edition
to 10,000. Plans are now being made for the
revision and printing of a third edition.
During this period, the PHOTO INTERPRE-
TATION MANUAL was prepared and is in the
process of being printed at the present time.
Although not yet ready for issue, orders for
approximately 1,500 copies have been re-
ceived. This Manual includes numerous illus-
trations in color which further enhance its
value.
The Abstracting Committee, organized to
cooperate with the International Training
Center, Delft, Netherlands, has been func-

at London, Sept. 1960.
