摘要
大型GIS系统中要存储海量的空间数据,需要面对大量用户高并发访问提供高效的服务,而传统的空间数据库设计方案难以满足需求。针对大型GIS系统中海量矢量数据存储组织,提出一种基于Hadoop的存储方案,并通过实验验证该方案的有效性。
Large GIS system stores huge quantity of vector data and needs to supply efficient service for multi-user concurrent ac- cess. Traditional design of spatial database cannot meet the requirement. To solve the problem of massive vector data storage in Large-GIS, we propose a new Hadoop-based method in this paper and demonstrate its effectiveness through an extensive experi- mental evaluation.
