摘　　要：为解决多源空间数据特别是不同参考基准数据实时集成困难的问题,通过分析空间元数据间关系,定义并利用元数据知识来实现空间元数据的动态聚合和目录服务SMCS的构建。实验结果表明顾及空间关系的SMCS提高了对空间信息的动态获取、处理和发布的能力和效率,为网格环境下多源数据的高效集成应用服务提供技术支持。It is key to grid geographical information service that how to integrate spatial data from distributed and multiple source, especially for the mnlti-geo-reference data. A metadata aggregation knowledge base has been introduced in this paper. And the spatial relation aggregation operations have been defined to construct spatial metadata catalog service （SMCS）. The service-oriented architecture based on SMCS have been proposed and improved to access, manage and distribute spatial data. The experimental results proved that the new application way based on SMCS could support efficiently run-time integration and share for multi-geo-reference data under grid environment.
