In view of time limitations I should like to proceed directly to the reading
of the first paper of today's program.
After reading his paper entitled "Long Distance Photography in Ground
Reconnaissance and the Possibilities it Gives for Photo Interpretation" Captain
Thorèn also read a paper, by Major B. von Vegesack of the Swedish Army,
entitled “Terrestrial Photographic Reconnaissance and Photo Interpretation
from an Army Point of View."
Thereafter, papers were given by C. G. Coleman and W. B. Cubby: J. H.
Roscoe; E. L. Rabben; and P. E. Truesdell.
The full text of each of the above papers, in English, and an abstract in
French appear elsewhere in these Archives.
INTRODUCTORY REMARKS BY LCDR COLWELL.
In the three preceding sessions of this commission we have considered the
various uses made of photographic interpretation in engineering, in natural
resource inventory, and in military intelligence, respectively. Since certain as-
pects of photo interpretation cut across all 3 of these fields, we are devoting this
fourth and final session of Commission VII to a consideration of papers which
for the most part are quite general in nature. The first of these papers will be
given by Mr. C. A. J. von Frijtag Drabbe, Director of the Dutch Topographic
Service, who will speak on the subject, “Techniques of Photo Interpretation.”
Following Mr. von Drabbe’s presentation, papers also were given by M. M.
Witenstein, H. J. O’Neill, S. M. Johnson, and A. H. Katz.
The full text of each of the above papers, in English, and an abstract in
French appear elsewhere in these Archives.
