NATIONAL REPORT TO THE TENTH INTERNATIONAL CONGRESS 
ing of the real goals to be accomplished. These solutions are of particular value 
in the collection of source data for emerging countries. 
In these, and in many other areas, progress in photogrammetry and allied sciences 
was real and vital, and the role played by the Society as a clearinghouse and often as a 
prime mover grew ever more important. 
What are the ways in which a National Society can exert such leadership? A look 
at some of the specific activities of the American Society may serve to answer the 
question. 
Publications 
The official journal of the Society, photogrammetric engineering, issued six 
times annually to members and over 1,000 outside subscribers, has maintained an 
increasing standard of quality of content and presentation, even though it has 
doubled in size in recent years. 
The Manual of Photogrammetry, published several years ago, has continued to be 
popular, and during the period since the last Congress, 2,000 copies have been sold, 
bringing the total sales to 12,000 copies, practically exhausting the current supply. 
Preparation of manuscript for a revised and enlarged third edition is under way, with 
the stated purpose of being a most complete and definitive work on the art and science 
of photogrammetry. Target date for publication of the new Manual is July 1, 1965. 
The Manual of Photographic Interpretation, issued shortly after the London Con 
gress has proven extremely popular, and, to date, about 7,000 copies have been sold. 
A News Letter containing items of interest to photogrammetrists is published every 
two months and has proven to be a most valuable means of communication. 
A brochure, entitled What About A Career in Photogrammetry?, was printed in 
1962 and already more than 10,000 copies have been distributed to interested or 
ganizations and individuals. 
A Services and Equipment Guide, published by the Society in 1963, giving valuable 
data on the nature and source of needed services and equipment, directly or in 
directly connected with the practice of photogrammetry, proved to be successful, and 
a second larger Guide will be published in January 1965. 
Meetings and Conferences 
The Annual Meetings of the American Society of Photogrammetry, held jointly 
with those of the American Congress on Surveying and Mapping have grown both 
in technical content and attendance. Last year, about 2,600 registrants attended the 
meetings at the Shoreham Hotel, Washington, D. C., and attended technical sessions 
on a host of interesting subjects held on four successive days. Over 90 commercial 
and 30 educational booths formed the largest exhibition of surveying, mapping and 
photogrammetric equipment yet assembled in the United States, and the 1964 
meeting promises to be even greater. 
Semiannual Meetings were held in New York City in 1961, in St. Louis in 1962, 
and at Wellesley Island, New York, in 1963. At all three of these meetings, complete 
technical programs were offered with a variety of speakers representing the best of 
private and Government expertise in photogrammetry. 
Society Organization 
The officers and directors of the Society are elected by the membership and repre 
sent the best cross section of experienced photogrammetrists. The National head 
quarters of the Society at 44 Leesburg Pike, Falls Church, Virginia 22044, is operated 
by a skilled permanent staff which efficiently handles a burgeoning load of corre 
spondence and administrative detail. 
Committees conducting the business of the Society are divided into Administra-
