In this paper,a way named meta-data adapter is proposed,which can interpreter original meta-data with different syntax and semantic rules to required meta-data so that they can be organized as a distributed,heterogeneous,uniform interfaced,and inherent features based virtual remote sensing data catalog.
提出了一种将具有不同语法与语义特性的元数据解释成为应用所需要的格式和语义的元数据适配器,并将元数据适配器使用到空间信息网格之中,基于数据的内在特性构建分布、异构、协同、单一访问接口的遥感数据目录,进而实现适合于空间信息应用的更加强大和灵活的数据网格。
