基于 Hadoop 的矢量空间数据库技术

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 .
