| 摘 要： | 针对在大型地理信息系统(GIS)中,需要对海量矢量数据和栅格数据进行存储并对高并发的用户查询请求提供高效响应,传统的设计方案难以满足需求的问题,提出一种使用基于内存存储的分布式数据库HBase存储空间数据,并设计基于GeoHash的分布式空间索引,实现了矢量空间数据与栅格空间数据的分布式存储与快速查询.实验表明,该方法提升了海量空间数据的查询速度.

| Abstract: | In large geographic information system (GIS), itwas necessary to store massive vector data and grid data to provide efficient responsefor users’ data query of high concurrency. The traditional design scheme was difficult to meet the demand. We proposed a distributed database HBase to store spatial data, which
was based on memory storage, and designed the distributed spatial index based on GeoHash, realized distributed storage and fast query of vector and grid spatial data. Experimental result shows that this method improves the query speed of massive spatial data. |
