基于地质信息元数据标准的多源空间数据管理系统

The multi-source spatial data management system based on geological information metadata standard

基于对空间数据特点的分析,结合当前的空间数据存储技术,通过对元数据标准的扩展解决多源空间元数据交换的问题;利用单机多空间数据库引擎(spatial database engire,SDE)数据存储技术解决多源空间数据定位及共享的问题;通过建立空间索引数据库,在单机多SDE的基础上,解决空间数据的快速检索定位的问题;从而实现多源空间数据的组织和管理,构建基于地质信息元数据标准的多源空间数据管理系统,为解决资源与环境遥感信息基础平台建设中的空间数据多源、空间数据共享及空间元数据交换打下基础。

Based on analyzing the characteristics technology, this study implements the organizatio Multi- source Spatial Data Management System. spatial data thematic diversity and data exchange of spatial data in combination with current spatial data storage n and management of multi - source spatial data and builds the For implementing the system, this study solves the problems of by extending the metadata standards, solves the issues like large amounts of data, distributed source and heterogeneous data format using single machine multiple SDE data storage technology, and finally, in order to solve the problem of fast retrieval localization of spatial data, systematically builds the spatial index database based on single machine multiple SDE. The system lays a good foundation for solving thematic diversity, data sharing and exchange which will be met in the information platform construction of muhi - source spatial data for the applications of resource and environmental remote sensing data.
