This set of programs was developed to plot positions of geological features on a map of Illinois or a portion of it. Illimap programs can interpolate between values of the parameters whose positions are shown by the plotted points, when the values represent elemental concentra- tions, soil composition percentages, or other continuously variable parameters. This interpolation results in constant value contour lines, which can also be.
