Abstract: | The author outlines a method for quantitative analysis of the completeness of information presented on maps of varying scale, i.e., for determining, upon reductions in scale of an original map A, what magnitudes of loss in graphic detail will result in derivative maps B, C, D that are of equal relative completeness to the original. Empirical formulae are derived which describe intensities of selection typical of maps devoted to particular topics (stream networks, urban socioeconomic indices, etc.) and graphic methods are described which can be used to determine scale denominators at which specific reductions in the number of features can occur without losses in “completeness” or, conversely, the number of particular kinds of features that can be eliminated on maps (or portions of maps) upon reductions in scale without losses in completeness.
