OGC(Open GIS Consortium)组织所提出的空间信息服务框架中包含多种需要消耗大量计算资源的计算密集型服务,如海量空间信息的存储与获取服务、影像处理服务等,但该组织并未对这类服务的具体实现方式及技术作出规定和说明.针对这类计算密集型空间信息服务,文章从技术层面研究了基于PC集群并行计算环境的计算密集型空间信息服务的实现方法及技术架构,为研究开发高性能的空间信息服务进行了探索.

There are a lot of spatial information services in the spatial information service architecture provided by Open GIS Consortium which are belonging to the compute-intensive service that they will expend a mount of computing resource, such as storage of spatial data in parallel databases, image processing etc. However, OGC has never described the technological implementation in detail. Therefore, the paper discusses the implementation and technological architecture for the compute-intensive spatial information service based on the PC cluster. The work the pa...
