【摘要】 基于面向实体及其关系的数据模型,对空间数据按照简单对象集、拓扑对象集、复合对象集、域对象集进行数据组织,并对关系型、对象关系型空间数据库的实现技术进行研究并提出解决思路,然后应用基于元数据管理的空间数据库集成技术实现对多源异构分布式空间数据库的集成管理。更多还原

【Abstract】 Based on the entity oriented and its relationship spatial data model,according to the data organization of the simple object collection,topological object collection,compound object collection and field object collection,this paper brings forward the solution of the relational and object relational spatial database,and realizes the multisources,heterogeneous,distributed spatial database integrated management on the spatial database integrated technology based on the spatial metadata management.更多还原
