PERFORMANCE OF PHOTOGRAPHIC INTERPRETERS AS A FUNCTION OF TIME AND IMAGE CHARACTERISTICS.

Abstract

Effects on photo interpreter performance of different viewing times, work-rest cycles, and image quality and content were studied. Results indicate that collection and processing agencies should avoid inadequate levels of scale, resolution, or contrast even at the expense of sacrificing high levels of any of these variables. Viewing times of 4 seconds for scanning and 60 seconds for identifying features seem adequate. In these times, the interpreter has extracted about 90% of the total information which he is going to extract. Over relatively short periods of time (four hours), varying work-rest cycles do not significantly affect accuracy or completeness of interpreters. (Author)
