Image format considerations in photographic intelligence processing. metricard design

The significance of the format of photos, maps, charts, and other graphic data is discussed in terms of the effects on efficiency of photo data reduction systems. The varied functions in such systems suggest many different format defining parameters. These parameters and their interrelationships are considered for the purpose of identifying formats of maximum utility for all such functions. It is concluded that a wide range of photo data reduction activities can effectively be accomplished with one standard size of unit record prepared from 70 millimeter roll film and containing an image with a minimum dimension very close to 2.25 inches. The other dimension of the image may require variation from 2.25 in. to a value about one-third larger to meet various geometrical and technical considerations. A description of such a standard format (Metricard) is presented. This format was designed to meet the requirements of photo data reduction systems emphasizing the features of rapid handling, moderate storage volume, and high information density. (Author).
