顾及局部特征的线状要素制图综合Line features generalization method based on local structural features
杨志坚
摘要(Abstract)：
针对传统的线状要素化简方法难以准确描述线要素局部结构特征的问题,该文提出了一种顾及局部结构特征的线状要素制图综合方法。引入m阶邻居坐标点概念,分析坐标点对线要素局部结构特征的贡献程度;建立了局部结构特征度量方法,实现了简单线要素的自动化简;基于该化简过程,从拓扑不变性角度顾及线状要素的整体形态及不同线状要素之间的拓扑关系,实现了复合线划网络的自动综合。基于对简单线划目标和复杂线划网络的实验结果表明:通过调整m的取值,可以完成不同尺度下线要素的自动制图综合,且化简结果较好地保持了原始线划要素的整体形态特征。
