摘要
结合当前的网格计算和网格数据库技术,从GIS集成运算与数据共享的角度概括了GridGIS包括应用层、中间件层与资源层三层架构的协同工作体系结构和宽带网络技术、分布对象技术、互操作技术与GML共享技术等关键技术支撑以及GridGIS服务组成结构等。
This paper combines grid computing with grid database technology.The system infrastructure and key technology are generalized.The former includes the application layer,the middleware layer and the resource layer cooperating for grid GIS.The later comprises key techniques for the Broad Band networks,the distributed object and component database,spatial interoperability and GML share for spatial data or services,including services framework of grid GIS.
