摘要
本文讨论了空间数据的拓扑关系,对地图的基本图形元素作了更准确的表述;详细介绍和讨论了自动生成空间数据拓扑关系的原理和方法,重点研究和探讨了并列和嵌套的面域拓扑关系。本文所述的方法适用于多种复杂的空间实体关系。
This paper discussed the topologic relationship of spacial data and gave an exact description of map graphic elements.It also introduced the principle and method of auto-establishing the topologic relationship, especially the parallel and inclusive area topologic relationship. This method can be applied in studying different kinds of complex spacial relationship.
