COMMAP is an automatic mapping system. It uses an automatic map reader for digitizing the input data, an IBM 704 computer for processing the data and a Benson Lehner Electroplotter for plotting and contouring the output. This system processes, plots, and contours all mappable data. Computations which can be preformed by the system include the following: (1) determination of regionals and residuals by polynomial surface-fitting techniques, (2) determination of regionals and residuals by various ring-average methods, (3) upward and downward continuation of potential field data, (4) first and second vertical derivatives by several methods.

This paper covers the system in general and gives examples of tabulated, plotted and contoured output of the results for a number of specific field problems.
