摘要 随着地理空间信息应用的不断增加,完成一个复杂的任务需要多学科多部门的参加与合作,因此有必要将目前孤立的GIS互操作、集成和融合。地理信息的互操作是集成和融合的基础。互操作可以在不同层次上实施,该文提出了5 个层次的互操作GIS模型。空间信息基础设施为地理空间信息共享和互操作提供一个共享的地理空间信息框架和体系结构,为GIS提供互操作的实施环境;从4个侧面提出空间信息基础设施的体系结构,并认为互操作GIS模型理论与空间信息基础设施体系结构有对应关系。互操作GIS模型为空间信息基础设施体系结构提供理论基础,空间信息基础设施体系结构为互操作GIS提供实施平台和环境。 Increasing application of Geospatial information requires integration , fusion and interoperability of current monolithic GIS, especially of more complex and multidisciplinary application. Interoperability is the base for information integration and fusion. A five\|level GIS interoperability model is given. The spatial information infrastructure (SII) provides a sharing spatial information framework, architecture and an interoperability platform for geographical information system. This paper studies architecture of spatial information infrastructure, and gives the relationship between GIS interoperability model and spatial information infrastructure architecture. We consider GIS interoperability model provides theory base for SII, and SII provides an implementation platform for GIS interoperability model.
