| 摘 要： | 云计算是基于网络的计算模型,通过构建云计算基础设施来为上层的云端应用提供支撑环境。将GIS与云计算相结合,能够为GIS的信息存储、处理及其应用提供新的发展前景。结合云计算与GIS,提出了基于云计算的GIS系统模型。以云计算的数据存储和透明化用户服务为基础,构建以GIS基础服务设施为服务支撑平台和以GIS基础信息数据与GIS应用程序为应用支撑平台。从而使GIS能够在通过云计算进行底层数据和服务的网络化资源分配,同时为用户提供稳定高效可靠的GIS服务。

| Abstract: | Cloud computing is a novel network-based computing model,in which the cloud infrastructure is con-structed in bottom level and provided as the support environment for the applications in upper cloud level.The combination of clouding computing and GIS can improve the performance of GIS,and it can also provide a new prospect of GIS information storage,processing and utilization.By integrating cloud computing and GIS,this paper presented a cloud computing based GIS model based on two features of cloud computing： data storage and transparent custom service.The model contains two layers： service layer and application layer.With this two-layer model,GIS can provide stable and efficient services to end users by optimized network resource allocation of underlying data and services in cloud computing. |
