在分析了空间信息的多尺度、不确定性、分形和领域背景特征的基础上,讨论了空间信息特征对网格结果的影响,提出了具有空间信息特点的信息网格的体系结构;为了解决空间信息基于语义的共享问题,提出了一种基于空间信息特征的网格语义转换和推理模式的设计方案.在一定程度上解决了空间信息基于网格服务的集成和互操作,推动了空间信息的社会化进程.
Grid is a new distributed computing technology which constructs on Intranet and can fully use various computing resource. Based on analyzing spatial information characteristics including multi-scale, uncertainty, fractal and domain background feature, the influences of the spatial information features on grid result are discussed; and a type of system structure of information grid which holds the characteristics of spatial information is put forward. In order to resolve the sharing problem of spatial information based on semantics, a design scheme about grid semantic conversion and reasoning mode based on spatial information characteristics is presented, which can settle the problem of integration and interoperation of spatial information based on grid service to some extent and finally promote the socialization progress of spatial information.
