Defining Map Contour Intervals in GS⁺

GS⁺ gives you complete control over  map contour intervals. In the Map Contour Intervals dialog you may change the default break points and colors for map contours. The number of contour intervals (1 - 15) is specified in the Map window. Customized intervals (both break points and color schemes) can be saved to allow different maps to easily share the same contouring schemes.  Clicking on a color tab brings up a color dialog window with the full suite of colors that Windows supports.  Missing values, including areas within "exclusive" polygons, are mapped as blank spots (background color).
