GIS环境下制图自动综合

Auto-generalization of Maps in the GIS Environment

借助 GIS的可视化以及 GIS的空间分析工具 ,制图自动综合的研究进入了一个新阶段 ;一方面 ,GIS扩大了制图自动综合的内涵 ,另一方面 ,制图自动综合推动了 GIS的发展 ,丰富了 GIS的研究内容。实际上 ,制图自动综合应该是 GIS系统的重要组成部分或应具有的重要功能。制图自动综合的研究手段和研究方法越来越丰富并取得了很大进展 ;在总结前人研究的基础上提出了 GIS分层支持下的面向地理特征的自动综合 ,实验表明这种方法是可行的 ,但仍然存在诸多问题 。

The new era of study on auto\|generalization has started based on the GIS visualization and spatial analysis tools. On the one hand, the connotation of automated map generalization has been broadened. On the other hand, automated map generalization advanced the GIS development, and enlarged the application field of GIS. In fact, it is the important part of GIS system or its functions to the automated map generalization . Approach and means of automated map generalization are more and more plentiful and great progress has been made. The paper points out geo\|features\|oriented auto\|generalization supported by different layeres in GIS. The experiment suggests it is practical, but most problems are still left to be solved, and its total solution must be based on the knowledge generalization.
