以多边形制图综合中的中心骨架线的提取问题为切入点,在分析比较常规多边形中心线提取方法的基础上,结合Model Builder流程化处理特点,提出新的制图综合设计思路---基于Model Builder可视化建模环境,利用泰森多边形中有关垂直平分线的特性提取原多边形的中心骨架线,相较于传统的提取方法其结果更为简便和精确。
以多邊形製圖綜閤中的中心骨架線的提取問題為切入點,在分析比較常規多邊形中心線提取方法的基礎上,結閤Model Builder流程化處理特點,提齣新的製圖綜閤設計思路---基于Model Builder可視化建模環境,利用泰森多邊形中有關垂直平分線的特性提取原多邊形的中心骨架線,相較于傳統的提取方法其結果更為簡便和精確。

With the problem of centerline extraction of polygons in map generalization as a starting point , and on the basis of reviewing and analyzing the traditional methods for centerline extraction of polygons ,this paper proposes a new method for mapping generaliza-tion.The specific idea is that based on the Model Builder visualization modeling environment , the centerline of original polygon can be extracted by utilizing the features of perpendicular bisector of Thiessen polygons .The results show that the method is more simple and accurate than the traditional methods .
