A New Technique for Map Generalization, Triangle Varying Filtering Model
() Abstract
This paper presents a new graph simplification model, the varying triangle filtering model, which not only considers the characteristics of computer cartographic generalization but overcomes the shortage of traditional methods as well. This model is easy to understand and operate. Meanwhile it can be used as a practical method in cartography generalization.
