319 COMMISSION VII Photographic interpretation President: Mr. C. G. Coleman Jr, ILS. A. Secretary: Mr. E. J. Rogers, U. S. A. Minutes of the Proceedings of July 18, 1956, Session a, photographic interpretation The session was opened by the president with the following statement: »The science of photographic interpretation has made great strides during the past four years, as those of you who have had the opportunity to view the Com mission report will agree. Photographic Interpretation (or PI, as it is often abbreviated) has been in formally defined as the act of identifying objects imaged on photographs and deducing their significance. Therefore it is somewhat more concerned with the nature of function of what is seen on an aerial photograph, rather than with the precise distances between objects. Photographic interpretation has therefore be come a very useful tool for many branches of science, some of those are: geo graphy, geology, forestry, engineering and the military sciences. We hope that the Commission VII sessions will serve to bring to light much that is being accomplished in this fast-growing field.» The president introduced Professor K. Stone of IJ.S.A. who presented his K. Stone: Air Photo paper, on Air Photo Interpretation Procedures: Interpretation Procedures. 1 (Publ. VII S 1 in General Air photo interpretation is a way of using research material. It is a technique Report VII) belonging to all fields of study with procedures similar to those of other research methods. Four general procedures are suggested for interpretation to be done: 1) in a methodical manner, 2) from the general items to the specific, 3) from the known features to the unknown, and 4) after analysis of the photographic quality of the coverage. Interpretation should be done topically and a topic at a time. A tested useful order of topics is: transportation, drainage, surface configuration, natural vegeta tion, agriculture, rural non-agricultural features, urban features, heavy industry, and special features. Recommended specific procedures for each topic are arranged on the basis of photographic scales in the order: 1) 1/70 000—1/30 000, 2) 1/30 000—1/10 000, and 3) larger than 1/10 000. From 10 to 21 specific procedures are outlined for each topic on the basis of the general procedures. Usually the specific procedures in the smallest scale category are based on observable non-technical characte ristics for large areas, those of the middle scale group on photographic appear ances and general knowledge of the content of the topic, and those of the largest scale category are dependent primarily on detailed knowledge of the topic. Too many interpretation keys resemble only the last of these categories. Des procédés d’interprétation de photos aériennes L’interprétation doit se faire sujet par sujet, un detail à la fois. Un ordre de sujets éprouvé et C’est une technique propre à toutes les branches d’étude avec des procédés pareils à ceux d’autres méthodes de recherche.
