Techniques and equipment for handling graphic data were the subjects of the study. The graphic data were derived from line maps, color separation sheets, orthophotographs and contour sheets. Equipment was tested, wherever feasible, by implementing hardware and software to enable the on-line communication between a human operator and a digital computer. The human factors of handling cartographic data with a cathode ray tube display equipped with a light pen were studied to a degree sufficient to obtain specific conclusions. An operational test system was used to obtain results of tests and to extrapolate the data obtained from these tests into possible system and equipment configurations. The test system consisted of a computational complex equipped with a graphical display with provision for human interface and augmented by a breadboard scanner-digitizer. The output of the system consists of an X-Y plotter capable of translating digital data into hard copy. Although the tests emphasized the human interface with a computational complex, the types of graphical data to be processed, the sources of this data, methods of handling data, and suggestions for solving the file conversion process were also investigated. These investigations are directly related to the graphical data handling techniques because it has been determined that any given technique or equipment will have many uses in the total cartographic system.
