Research on scalable cluster-based cloud GIS platform
基于集群技术的可伸缩云GIS服务平台研究

In order to build a scalable, on-demand cloud GIS platform which was able to provide OGC complaint Web services, this paper studied the features and requirements of cloud GIS. Accordingly, it leveraged server cluster and distributed cache technologies to design and implement a cloud GIS platform. The experiment testified its scalability of dealing with high-concurrency and computational intensive tasks. The result of experiment shows good speed up ratio. In addition, the platform performed well in real GIS application.
