摘要
以局域基本拓扑关系的抽象为基础,着重阐述了线与线之间局域拓扑关系抽象的规则,并研究了相邻两类局域基本空间拓扑关系合并的规律,提出了在空间抽象过程中渐进式删除局域拓扑关系的方法。
Graphic simplification can cause the transformation of local topological relations between lines, line and region, regions and that after combinatorial. On the basis of abstraction of local topological relations, the rule of local topological relation between lines is emphasized, and the disciplinarian of combining the adjacent local topological relations is investigated. The method of deleting local topological relations is proposed.
