地质图空间数据库建设中的拓扑关系处理

DISPOSAL OF TOPOLOGICAL RELATION IN CONSTRUCTION OF GEOLOGICAL MAP SPACE DATE-BASE

拓扑关系是空间数据库的核心。主要阐述拓扑关系的基本概念，详细介绍MAPGIS和ARC/INFO两大模块中，拓扑关系具体表现形式、处理方法及处理过程中的注意事项，形成了一套较为完善的工作流程，提高了工作效率，为今后的信息化提供了行之有效的工作方法。

Topological relation is the core of space date-base. The basic concept of topological relation was mainly set forth. The material representative forms, methods to dispose and notices in disposal of the two modules of MAPGIS and ARC/INFO were particularly introduced. A perfect process flow was formed. Work efficiency was improved. This was an effective way in processing information in future.
