摘要
为了消除城市地理信息系统中的信息孤岛,研究了可以动态服务装配和松散耦合集成的城市地理信息服务集成框架。采用最新的网格架构体系——OGSA,建立一个虚拟组织,在虚拟组织中,可共享的城市空间信息以网格服务的形式提供给用户或应用。应用和用户能够创建临时服务,还可以发现这些服务并得到其特性。基于OGSA的城市空间信息共享的虚拟组织的建立,实现了可跨越异构、地理分布环境中的城市空间信息的访问与集成,为空间信息全面共享提供了实用可行的解决思路和实施方案。
In order to break bulwark of different organizations and eliminate the information isolated island, an integration framework for invoking services automatically and incompactly is proposed. A virtual organization (VO) is set up based on open grid service architecture (OGSA). In the VO, all spatial data for share is encapsulated into grid services for clients or applications, which can create temporary services and discover these services and their attributes. By the construction ofVO, integration and share ofgeological spacial data located in different area is realized. As a result, the design can be uesd to guide the all-sided implement of spacial data share.
