摘要
随着近年来测绘地理信息应用的拓展和深入,海量实时地理位置数据的处理需求日渐增多。本课题为解决重庆市公安局交通巡逻警察总队警车GPS点位实时数据处理需求,提出了一种实时地理位置数据分析技术。通过引入地理围栏、定义地理事件,利用Map-Reduce算法结合空间拓扑特性对数据进行处理,取得良好应用效果,使警务数据统计处理效率得到较大幅度提升。
With the development of geographic information applications in recent years, the demand for real-time lo- cation data processing and analysis is increasing. In order to solve the problem of real-time data processing requirements of the GPS points of the police car in Chongqing, this paper presents a real-time location data analysis technique. The geographic fence and the definition of geographic events are introduced. The data are processed by Map-Reduce algo- rithm and the spatial topological characteristics are obtained. The efficiency of data processing is greatly improved.
