介绍了MODIS数据共享与资源服务现状,研究了一种基于3层结构的MODIS数据服务模型,详细介绍了数据服务模型的管理和分发机制。为了确保数据服务模型的可扩展性和平台无关性,设计了基于XML的可扩展性数据访问语言和数据目录服务。最后给出了在空间信息网格试验床上的示范验证,并对实验结果进行分析。 更多还原

【Abstract】 This paper presents a research on utilizing the data grid technology to integrate heterogeneous distributed MODIS data sources.We studied and implemented a three-layer structure for data interoperation,and designed an extensible XML-based spatial data access language to support the cross-border data computation,and developed a data catalogue service to facilitate users.The system deployed on Spatial Information Grid platform,and the performance is introduced finally. 更多还原
