COMMON AREAS IN EARLY AND LATE IMAGERY, ANNOTATION OF TARGETS ON EARLY IMAGERY, AND USE OF A LIST OF TARGETS APPEARING ON THE EARLY IMAGERY. Principal findings of the study show that the presence or absence of common area demarcation had no significant effect upon the mean number of correct change detections in any of the three change categories providing the interpreter with target information in the early cover significantly increased mean number of erroneous change detections use of target lists also increased the mean number of correct detections, but at the same time increased the number of false alarms and increased working time by about 20 percent combined use of target annotations and target lists to provide information about early cover imagery appears to maximize the number of correct change detections.
