基于遥感数据访问与集成的网格中间件

借助数据网格强大的数据管理功能，可以整合分散复杂的遥感数据，为遥感数据处理提供一致的存取环境。遥感数据访问与集成网格中间件的研究目的是为访问分散的、异构的遥感数据提供统一的网格服务接口，使孤立的遥感数据之间实现资源共享。该文利用OGSA-DAI设计，实现了遥感数据访问和集成网格服务，构建了一个高性能遥感数据共享系统，分析了系统的关键性技术及实际应用。

Grid Middleware Based on Remote Sensing Data Access and Integration

The powerful data management function of data grid allows us to integrate distributed and complex remote sensing data, and provides a consistent grid environment for storing and retrieving remote sensing data. The research on grid middleware of remote sensing data access and integration attempts to provide standard interfaces to access distributed and heterogeneous remote sensing data, and to make the isolated remote sensing data be shared between each other. This paper designes and implementes grid services of remote sensing data access and integration via OGSA-DAI, builds a high performance grid system to share remote sensing data. It analyzes key technologies in the system and describes a practical application of the system.
