摘要
该文提出建立分布式多空间数据库系统来实现异构空间数据源的互操作 ,以达到空间信息共享的目的。首先介绍分布式多空间数据库的基本概念、系统结构以及关键技术 ;其次 ,通过对空间数据分布特征的分析 ,提出了多空间数据库系统集成的基本思路“异构同化 ,同构整体化” 。
Data sharing has been the bottleneck problem that prevents the development of GIS applications. The author brings forward to implement the spatial data sharing by establishing the multi-spatial database system. First, the author discusses the basic concepts, the system structure and the key technology of distributed multi-spatial database system, Second ,the author brings forward the basic idea about integration of the distributed multi-spatial database system, namely 'assimilating the heterogeneity, and unifying the homogeneity', and establishes the layer model of integration.
