摘要 空间拓扑关系的描述是空间关系的主要内容,是与人类的认知概念一致的,在空间数据的查询与挖掘等方面有重要应用。回顾了现有模型,然后重点分析了其中的四交差模型,提出了四交差简化模型,同时对简化了的四交差模型的合理性进行了详细分析,最后展望了四交差简化模型及其应用中有待进一步研究的相关工作。 The description of topological relations,which is in line with cognition concepts of human,is one of the main contents in the special relations and plays important roles in spatial data inquiry and mining.First,we reviewed the current exsiting models.Subsequently,we analyzed 4-intersection-difference model and set up a simplified 4-intersection-difference model.In addition,we made detailed analysis on the rationality of simplified 4-intersection-difference model.At last,we prospected related research work on simplified 4-intersection-difference model.
