REPORT OF COMMISSION VII GVÏI-55 determined as to position. This is an especially intricate problem in the case of low alti tude photography, all the more so when the pilot has been forced on account of enemy activity to relinquish the set course of flight. “The determination of position of aerial photographs must frequently be carried out by comparing the terrain on the photos with either a map or, still better, with a series of wide angle photographs whose position is known. (The pilot’s idea of the posi tions of the photo strips is often too diffuse to render more than a rough orientation of the strips.) A special photographic memory is necessary for the determination of posi tion of the photos. By means of constant practice, however, it is possible to become proficient in this determination. For this angle of interpretation a special group of personnel should be available, here called position determinators. This group should, however, have a certain training in recognizing the simplest outlines of military objects (fortifications, vehicles, battery emplacements, the general outline of aerial strips and guided missile runways, different types of vessels, etc.) in order to be able to report such information regarding military objectives which they may have gathered while scrutiniz ing the photos in question. “During the determining of position, the photographed area should be delineated on a map, showing the general position of each photograph. “Selection of photos for interpretation “Through knowledge of the existing strategic position, and sometimes in accordance with suggestions from the position determinators, photo series are selected which have been found to cover the proposed target area. If other information regarding the enemy is available, from earlier photo missions or from other sources of intelligence, it is often possible to decide which photos contain the most important information and conse quently are to be given interpretation priority. This decision should be made by an officer who can appraise the existing military situation. The selection of the photos is carried out simultaneously with the determination of position and thus it causes no delay. As a rule the sector of most current interest is known before processing begins. As soon as the photo strips covering the area is question are determined as to position the series is passed to the interpreters. “Interpretation “The interpretation of the photos is done by interpreters in the usual manner. It should be possible to begin this work as soon as photo strips of the terrain of current interest have been sifted out by means of determination of position. The interpretation must be carried out simultaneously over a large area in order that the photo material at hand may yield information quickly enough. “Since a large number of different targets, especially at the beginning of a war, can not be recognized even by qualified photo interpreters, it is desirable that specialists on guided missile weapons, field fortifications, vehicle types, vessels, planes, etc., are avail able to assist the interpreters at their work. “The results can hardly be said to offer any new problems, and will not be expati ated upon. “The results of photo interpretation constitute an excellent basis for the study of enemy tactics. If the reconnaissance is carried out at regular intervals a good general view of enemy movements is acquired. “It is a fact that atomic weapons must cause changes of tactics and warfare tech nique. No prediction can be made as to how the enemy proposes to do this. It is, however, possible by means of such intelligence as may be acquired through photo interpretation to form a fairly accurate opinion in the matter. It is therefore important that the results achieved by the photo interpreters are studied from a tactical point of view as well. For this purpose specially qualified personnel should be detailed, persons whose training makes them capable of deducing the principles put into practice from the study of se quences of aerial photographs of any given area. The mission of ‘tactical photo inter preters’ is of great importance.
