摘要
在探讨Hadoop技术原理的基础上,提出了"Hadoop Spatial"分布式空间数据库系统的建设方案。基于原有的空间数据库设计方案,依托GIS方法和数据库技术以及对Hive的扩展形成了一个完整的分布式空间数据库系统。对比实验表明,Hadoop Spatial系统的性能不逊于SDBMS,更适用于分布式的计算密集型的查询。
The basic principles of Hadoop are discussed. A distributed spatial database system named ＂Hadoop Spatial＂ is proposed which building program based on Hadoop. Based on GIS and database technology and the extension with the Hive, the system has enough functions including effective storing data and highly effective managing spatial data. The distributed spatial database is fulfilled at last.
