中文摘要:

      遥感技术是国家解决资源短缺与环境问题的重要手段。广大用户对卫星遥感数据的需求十分 迫切，急需能够有效共享的遥感数据。网格技术能够在不改变现有体制的前提下，可以将分布的数据资源统一起来，促进数据的有效共享。文章总结回顾了国内遥感地面系统的现状及国内外遥感数据共享的特点，分析了我国遥感数据共享存在的问题，提出了利用网格技术解决遥感数据共享问题的方案。作为应用实例，文章描述了欧洲地球科学地面协作网—数据仓库（GENESI-DR）网格平台的核心结构及其实现的功能与应用方向，表明了该方案的正确性和可行性。

英文摘要:

      Remote sensing technology is an important means to resolve resource shortage and environment problems. Satellite remote sensing data which can be shared efficiently are much in demand. On the premise of the system in existence, distributed data resource can be integrated by grid, which will promote the effective sharing of remote sensing data. In this paper, the status quo of remote sensing ground processing system at home and the characteristics of remote sensing data sharing at home and abroad are summarized. On the basis of the analysis of problems of remote sensing data sharing in our country, a plan of remote sensing data sharing through grid technology is provided. After describing the core architecture of the ESA grid platform GENESI-DR and its functions and applications, the validity and feasibility of the plan are indicated.
