    Abstract: One or more small-scale maps are generated automatically and directly from a single large-scale map or database. A subset of geographic features to be represented in the small-scale map is selected based on the scaling law. The geographic features in the subset are determined based on topological connectivity, size, bend size or point density characterizing the geographic features, so the subset includes the larger or more connected or with higher density among the geographic features.
