VISUALIZING CARTOGRAPHIC GENERALIZATION

Map generalization is a complicated and not well-understood process. In order for users to go beyond the simple and arbitrary application of generalization operators, and accompanying tolerance values, to features in databases, visualization techniques must be designed to allow a better understanding of the effects. Through such visualization users can quickly understand, and adjust, their decisions. This paper proposes, given an existing framework of the generalization process in both vector and raster mode, a series of techniques for visualizing the outcome. Several graphic examples of such techniques are provided.
