A conceptual framework was proposed which conveniently summarizes a multitude of specific activities, which when taken collectively, com-prise a significant portion of the image interpretation process. Usually, these activities are either informally or formally organized into sequences of behavior guided by a desire to follow certain general rules. In this study, quantitative criterion data, based upon user needs, were obtained which permit derivation of clear image interpretation strategies. If followed, the strategies should allow interpreters to maximize the worth of their reports. The data are particularly applicable to the task of interpreting ambiguous or incomplete imagery.
