海量城市空间数据资源汇集模块的设计与实现

Design and Realization of Massive City Spatial Data Resources Marshal Module

研究了OGSA-DAI网格中间件技术,设计了一个基于OGSA-DAI的海量城市空间数据资源汇集模块,实现了城市地理空间信息的共享应用。本模块的创新之处在于扩展了OGSA-DAI的数据资源,实现网格环境下多源异构空间数据的访问与集成,对相关研发工作的开展起到了很好的借鉴作用。

We research the technoh）gy of grid middlcware OGSA-DAI, design a massive city spatial data resources marshal module, realize the share and application of city geospatial information. This module extends OGSA -DAI data resources, realizes distributed heterogeneous geospatial data access, integration and management in grid environment. It has played a very good reference to relevant research and development.
