摘　　要：基于元数据技术,针对具体的应用需求提出了元数据库的结构设计方案,并将其映射到关系数据库中进行存储。在此基础上设计并实现了多源空间数据的集成管理平台,以统一的数据接口为上层应用提供数据服务,克服了异构多源数据数据格式、存储位置、数据访问策略的差异给系统集成带来的困难,并为集成系统提供了平台支持。On the basis of metadata standard,a design scheme for the metadata base structure was proposed according to specific application requirements in this article,which was mapped to relational database and then was saved.On this basis,an integrated management system platform for multi-source spatial data was designed and realized.This platform offered the data service for the upper-layer application through the uniform data interface,conquered the difficulty of information system integration brought from the differences in isomeric multi-source data format,data storage location and data access strategy,and provided platform support for constructing the integrated system.
