| 摘 要： | 数据网格的发展促进了空间信息的协同合作和资源共享,然而,随着空间数据源呈现出越来越明显的分布性、异构性和动态性特点,如何实现大范围乃至全球范围的无缝集成和应用成为重要的研究课题。空间信息的数据特征和管理机制决定了只有在一个开放的、分布的系统平台上,才能实现全面的管理、共享和使用。本文论述了如何借助数据网格研究分布式空间数据协同操作和控制技术,提供一种服务一致化技术,将各种分布异构的数据资源通过网格化过程来实现数据服务的标准化,为用户提供一致化的接口。并对其中的研究重点进行了详细讨论。

| Abstract: | The development of data grid technology promoted the cooperative computing and resource sharing in spatial information area. But the spatial data resources have more and more obvious characteristics with distribution,heterogeneous and dynamics data. How to achieve large scale and global scope of spatial data application and seamless integration has become an important research topic. Based on the characteristics and management mechanism of spatial information,it can only realize the overall management,sharing and applying with an open and distributed system platform. This paper discussed how to study distributed spatial data cooperative operating and control technology with data grid. It provided a kind of coherence services technology to realize the standardization of data services for various distributed heterogeneous spatial data and provided standard interface for the users. It also detailedly introduced the research emphasis. |
