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-
