Remote Sensing Data Organization Model Based on Cloud Computing

为了解决云计算环境下海量遥感影像数据的存储问题,研究了一种支持云计算的遥感影像数据组织模型(RSC-DOM)。在深入分析目前遥感影像数据管理现状的基础上,详细剖析了云计算环境下遥感影像数据组织模型的关键性要素,其涉及到支持扩展的分布式存储模式、存储站点结构以及虚拟磁盘空间结构等问题;构建了基于云计算的分布式存储模型架构。实验结果表明,所提出的存储模型在实际应用中比传统依赖Oracle的数据管理方式具有一定的优势。

To solve massive remote sensing data storage problem in cloud computing environment,a remote sensing ima- ge data organization model based on cloud computing（RSC-DOM） was put forward. A concept about Virtual Disk Space （VDS） was adopted to meet the requirement using direct addressing method in distributed storage environment. The distributed storage architecture, VDS file architecture in cloud computing were analyzed, and remote sensing stora- ge architecture was built. Experimental results show that the proposed model is convenient to search, and its efficacy is greater than the traditional Oracle management style.
