pean contributions to the development of precise stereo plotting and triangula 
tion instruments will undoubtedly stand out for years to come as major achie 
vements in the field. American contributions of recent years lie in improvement 
in techniques of application, in the quality and procurement of aerial photo 
graphy, and in the use of photogrammetric methods on a massive scale to over 
come the overall deficiency in adequate mapping. 
To my mind, the use of the full potential of the photogrammetric method 
has not yet been realized. We are still too reliant on field engineering to supple 
ment the office technique. This is not true simply in the problem of geodetic 
control but in a much greater sense in the realm of photo identification or 
interpretation. We must strive to minimize, and eventually to eliminate, our 
need for field inspection. You specialists in photogrammetry are far better 
qualified than I to seek the solutions to these problems, but I point them out as 
being of significance. 
They are of particular importance to the military. It is rare indeed that in 
time of conflict we have a chance to do ground reconnaissance in enemy terri 
tory. Rather, we often consider ourselves fortunate if we secure adequate aerial 
photographic coverage of the area involved. It is because of this condition that 
we must develop more accurate methods of determining both the horizontal 
and vertical positions of the air camera at the time of exposure with little or 
no recourse to ground control. We must also learn to make positive identifi 
cation from the photographs not only of all the works of man, but also of the 
unusual natural features. 
This Seventh International Congress of Photogrammetry presents a won 
derful opportunity to examine the status and direction of our combined photo 
grammetric efforts. We are at an interesting stage in the development of equip 
ment and technique. Part of the European emphasis still seems to be in the 
development of more precise stereo plotting instruments. This is an admirable 
undertaking and of unquestionable benefit in the future. The American accent 
has been on the utilization and modification, with developmental improve 
ments, of the existing instruments, in a program aimed at increasing the cove 
rage of adequate mapping. 
I, myself, am not a photogrammetrist but I fully realize that any major 
military operation is severely handicapped without advance photogrammetric 
intelligence. Consequently, the perfection of the photogrammetric equipment 
and techniques of the free nations of the world — the objective of this Con 
gress — is of the highest importance. 
Each delegate here is free to offer his scientific opinions and equally free 
to criticize in a truly scientific spirit the opinions and work of his international 
colleagues. Out of these many divergent views a more complete and accurate 
view will result, leading to the development of many more ideas and resources. 
It is not my intent, in emphasizing the role of the photogrammetrist in 
direct map preparation, to ignore the countless other tasks accomplished thru 
photogrammetry. I fully realize and appreciate the vital importance of the 
photogrammetrists who compile from photography the military intelligence 
data relating to structures, transportation and communication routes, port faci 
lities and landing beach sites, to mention but a few; or who survey forest and 
timber reserves or prepare farm crop reports. All of these individuals, and the
