| 摘 要： | 通过对多重表达情况下空间数据一致性的分析,给出了一种在表达层同构情况下通过对象属性特征匹配过程和对象空间关系匹配过程来维护空间对象之间一致性的方法,该方法考虑了空间对象的属性特征一致性和拓扑关系一致性,可以更全面地解决地理信息系统中多重表达情况下空间数据的一致性问题,同时能更有效地提高空间数据的质量.

| Abstract: | A way to maintain the consistency between objects in the context of multiple representation of spatial data,is presented.It is achieved by object attribute feature matching process and object spatial relationship matching process under the representation level homomorphisms.The method considers the attribute feature consistency and topological relationship consistency of spatial objects together.It can solve the inconsistency more completely and improve the quality of spatial data more efficiently. |
