导航电子地图作业划分的改进

Improvement of Navigation Electronic Map Work Division

针对导航电子地图快速更新的问题,从内业制作环节出发,以成都市城区范围更新为例,提出了一种工单作业模式。通过任务划分、作业量与工期测算等过程分析,证明了相较于传统图幅作业模式,工单作业模式能较大程度地缩短工期,为快速更新提供参考。同时,从路网连通性的角度考虑,工单作业模式在微观层面上有利于制作路口交通信息,在宏观层面上可减少路网整体形状与属性的接边次数,从而降低发生数据质量问题的风险,更好地为导航功能的实现奠定基础。

In view of the rapid update of navigation electronic map,taking the urban area update of Chengdu City for example,we put forward a mode of work order operation.Through the process analysis of task division,workload and duration calculation,we proved that compared with the traditional map operation mode,the work order operation mode could shorten the construction period,provide reference for rapid update.At the same time,considering road network connectivity,the work order operation mode is conducive to the production of intersection traffic information at the micro level,and can reduce the connection times of overall shape and attributes of road network at the macro level,so as to reduce the risk of data quality problems and better lay the foundation for the realization of navigation functions.
