PROCEEDINGS OF COMMISSION VII 
INTRODUCTION OF PROFESSOR SMITH BY LCDR COLWELL. 
Today we are to hear a series of papers devoted to the subject “Photo In- 
terpretation in Engineering.” 
The Chairman for this phase of Commission VII happens to be a man 
named Smith; the honor of introducing him to this distinguished group falls to 
me. 
When introducing a person by the name of Smith, care must be taken to 
avoid ambiguity as to exactly which Smith is referred to. One distinguishing 
feature of today's chairman is that he has more letters in front of his name than 
most Smiths; he is known the world over as H. T. U. Smith. A second point of 
distinction is that he also has more letters after his name than most Smiths, name- 
ly B.S., M.S., Ph.D., reflecting the degrees awarded him at College of Wooster 
and at Harvard University. 
But the man I am introducing is more than a man of letters. There prob- 
ably are few people in this audience who have not become acquainted with his 
activities in one field or another. Most of us recognize and admire him as the 
author of an outstanding textbook entitled “Aerial Photographs and Their Ap- 
plications.” Some know him as a Professor of Geology at the University of 
Kansas. Others made his acquaintance during World War II when he rendered 
outstanding services to the military as a photogeologist for the U.S. Geological 
Survey. Still others know him for his work with the National Research Coun- 
cil, the Office of Naval Research or other important organizations with which 
he has identified himself. 
To extoll further the merits of our chairman would only detract from 
the very worthwhile program that he has arranged for today's meeting. There- 
fore, without further comment I proudly present your chairman, and the first 
speaker for today's panel, Professor H. T. U. Smith. 
Acknowledgment by Professor Smith: 
Thank you, Commander Colwell, for your very gracious remarks. With 
your approval I shall proceed directly to the presentation of papers on photo 
interpretation in engineering. 
Presentation of papers was then made by H. T. U. Smith, W. H. Simon- 
son, M. M. Elias, S. H. Spurr, R. L. Anderson, H. L. Cameron and B. Roelofs. 
The full text of each of these papers, in English, and an abstract in French 
appear elsewhere in these Archives.
