变三角形滤波法一种新的图形概括模型

简要介绍了两种传统的图形概括模型的基本原理和方法，并针对它们所存在的一些缺陷，结合计算机制图综合的特点，提出了一种新的图形概括模型－变三角形滤波法。该模型易于理解，操作简便，可做为一个实用的制图综合数学模型。

A New Technique for Map Generalization, Triangle Varying Filtering Model

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.
