摘要
由于GML空间数据的急剧增加,单机存储已不能满足其发展的需要,为了能够更好共享和管理网络地理信息以及针对海量GML数据的存储问题,本课题研究在分布式环境下对GML空间数据进行存储,进而提高资源利用率。搭建Hadoop平台对GML空间数据按其模式分为不同的数据集,把同一数据集的数据分别存储在不同存储节点上,并用一个主目录节点来存储用户信息和各个数据存储节点信息等元数据。
Due to the rapid increase of GML spatial data,standalone storage already cannot satisfy its development needs,in order to better sharing and management network,and the view of the mass of geographical information,the data storage GML study of this subject in distributed environment of GML space data storage,and improve the resources utilization.Build for Hadoop platform according to their model of GML spatial data divided into different datasets,put the same set of data stored in the data are different storage nodes,with a main directory node to store user information and each data storage nodes information metadata.
