  sig service
    Based on building open seven-layer application architecture o f SIG, we put, in the research, emphasis on SIG service composition. A novel ser vice comp osition model named service/resource net (SRN) is proposed based on Petri net an d graph theory. Moreover, an innovative service selection model (SISM) is presen ted to implement the dynamic service selection in the process of SIG service co mposi tion.
    在构建开放性SIG七层应用体系的基础上,重点研究SIG服务聚合技术,基于Petri网和图论提出了一种新的服务聚合流程模型(服务/资源网),同时构建了可扩展的服务动态选择模型(SISM),实现服务聚合过程中的动态服务选择。

Some problems in the application of spatial informa tion, s uch as distributed enormous data, heterogeneous format, complexity of processing and intensive computing have been obstacles to realize wide sharing a nd integration of spatial information.

Based on building open seven-layer application architecture o f SIG, we put, in the research, emphasis on SIG service composition.

Moreover, an innovative service selection model (SISM) is presen ted to implement the dynamic service selection in the process of SIG service co mposi tion. In accordance with the application requirements of the national geological survey, an application example of ground water evaluation is given and the validity and usability of SIG are verified.

空间信息应用中存在的数据海量、分布异构、处理复杂、计算密集等问题制约了空间数据和信息的广泛共享和应用。空间信息栅格(SIG)以Grid和WebServices技术为核心,共享并汇集地理上分布的海量空间信息资源,实现动态整合与集成。在构建开放性SIG七层应用体系的基础上,重点研究SIG服务聚合技术,基于Petri网和图论提出了一种新的服务聚合流程模型(服务/资源网),同时构建了可扩展的服务动态选择模型(SISM),实现服务聚合过程中的动态服务选择。结合国家地质调查业务应用,通过地下水资源评价应用实例对SIG的实用性和有效性进行了验证。
