In the world of mapping, charting and geodesy (MC&G) image processing, the amount of knowledge a person must bring to bear is one of the deepest intellectual questions today. The human being looks for meaning wherever possible and develops ways to organize things perceptively even if he has to invent ways of doing it. This process leads him into a wide range of information processing activities and technologies to assist him in achieving image exploitation goals in the most effective and efficient manner. Within a given area of MC&G interest, any set of procedures developed must give him the capability to process all required information within a scene regardless of its diversity. This makes it mandatory that his range of image processing cannot be limited to just techniques of image manipulation, but must involve a total system concept starting from the particular attributes and capabilities of the human mind, i.e., the processes and paradigms used by that mind in the accomplishment of its tasks, the equipment and methods by which that mind interacts with source image materials and the computer processes used to extract information. All of this must be accomplished at rates commensurate with mapping large regions of the world, within relatively fixed periods of time, at a variety of scales and detail densities using input photography also varying over a wide range of scales and ground resolutions.
