Abstract
A computer program and a method incorporated therein, called ContourFill, provides several features that enhance the display of contour maps. Even without using color, tick marks and gray-scale shading provide useful and cheaply reproducible representations of contoured surfaces. More dramatic effects are achieved when using color. Occasionally localized peculiarities are observed in the graphical outputs. These are usually traceable to data illegalities such as intersection of contour lines with other lines or penetration of contour lines into blanked areas. The localization of such effects is a tribute to the robustness of the computational algorithms.
