A Grid-Time-indexed Cube Model for Spatiotemporal Data Warehouse of Vehicle Supervision

  • 摘要: 分析了车辆监控数据和应用的特点,设计了车辆监控的时空索引机制和车辆监控数据仓库。利用广东省重点车辆监控数据实现了车辆监控数据仓库,并与传统数据库管理方式的效率进行对比分析表明,设计的时空数据仓库能够满足海量车辆监控数据管理和分析的要求。

     

    Abstract: Immense amounts of spatiotemporal data generated by vehicle supervision can't be efficiently managed by ordinary databases,due mainly to long query response.This paper proposes a new approach called grid-time-indexed cube,which is a spatial grid indexed,adaptive cube-based and trajectory supported for spatiotemporal data warehouses.Through the extensive performance studies based on spatiotemporal data from main vehicle supervision system of Guangdong province,we observed that grid-time-indexed cube achieved higher query performance than ordinary data storage technologies,under various operational conditions,and it was easily applicable in practice and compatible with ordinary databases.
