| 中文摘要: |
| 全球综合对地观测系统旨在建立全球性的数据共享框架，为各国组织共享和使用对地观测资源提供技术
解决方案。该系统的通用基础设施包括标准和互操作注册中心、组件和服务注册中心、分布式查询服务中心、资源门
户4 个部分。文章介绍各个组件的作用和相互间的关系，分析向全球综合对地观测系统提供共享资源的类型和技术流
程，提出该系统对国内科学数据共享实践的启示。 |
| 英文摘要: |
| The Global Earth Observation System of Systems (GEOSS) is a new generation of Earth observation
resources sharing framework initialized by the Group on Earth Observation (GEO) in 2005. The GEOSS Common
Infrastructure (GCI) has been established to enable the registration of, discovery of, and access to the sharable Earth
observation resources. The GCI consists of the following components: the Standards and Interoperability Registry,
the Component and Service Registry, the Clearinghouse, and the GEO Portal. The Standards and Interoperability
Registry maintains the list of GEOSS-endorsed standards and interoperability protocols. The Component and Service
Registry is the master directory of all the GEOSS-wide sharable Earth observation resources. The Clearinghouse
fulfills the distributed search to make metadata information about the Earth observation resources available through
Application Programming Interface. The GEO Portal presents a Graphical User Interface for users to discover the
Earth observation resources of interest. This paper introduces each of these GCI components, and their relationships.
It presents several scenarios for resource providers to follow when contributing Earth observation resources to the
GEOSS. It also concludes the lessons learned from the design and implementation of this system. |
