This article shows that cartographic generalization is best viewed as representing (formulating, renaming knowledge) and abstracting (simplifying a given representation). The general process of creating map is described so as to show how... more

We propose a novel approach to selection of important streets from a network, based on the technique of a self-organizing map (SOM), an artificial neural network algorithm for data clustering and visualization. Using the SOM training... more

Channel networks near Inez, Kentucky, were surveyed in the field within 29 small drainage basins that appeared on 1 :24,000-scale maps to be unbranched (first order). The basins contained from 0 to 5 channel sources, with an average of... more

Summary. In multiple scale presentation of vector data, there is a need to generalize and reduce the amount of data. In case large amounts of line segments and vertices appear, it is to encounter the two main problems. They are the... more

Model-oriented generalization modifies the internal representation of a map to make it simpler. We present a layered library supporting this task, based on a separation of the topological, metric and semantic aspects of maps. We outIine... more

This article describes a new automatic quadtree-/octree-based and scale-dependent generalization algorithm for point selection. The benefit toward existing point selection methods is that it preserves global as well as local... more
