Analysis

I.                    The development of analytical techniques.

 The first analytical techniques would consist in detecting the straight lines characteristic of man-made activities such as those related to roads, cities and airfields. Once patterns of  unit locations and concealment were detected, artillery and aircraft would attack the now discovered targets. With time, more detailed analysis would become possible, to include a pre-invasion photo mission during world war two that revealed a certain number of latrines. Current knowledge on Japanese sanitary regulations would be used to determine almost to a man the size of that island’s garrison which was confirmed once hostilities ceased. In spite of the introduction of color photography, black and white, because of the detail, would continue to be used.
