摘要： 多比例尺GIS中的数据库多重表达是当前国内外GIS领域的热点、难点问题之一。文中首先给出了对该问题的内涵界定,然后阐述了多重表达数据库的组织结构、数据更新方式、数据一致性问题等的设计方案,并提出了对多重表达数据库的数据一致性问题的看法,最后讨论了作者应用数据库多重表达技术在电子地图多级比例尺显示、层次性地理空间推理两个实例。

Abstract: Multiple Representation of Master Database (MRMD) in Multi-Scale GIS is one of the key problems in GIS realm.In this paper, the authors defined, at first, the intention of the problem, and then related their design to the structure, data updating mode, data consistency of Multiple Representation Database.Finally, some application examples of MRMD were described, including multi scale displaying of electronic maps, spatial hierarchical reasoning for geographic objects.

Key words: multi scale GIS, multiple representation, generalization
