| 摘 要： | 基于简单通用、安全、便于移植的原则,结合物流车辆监控电子地图的实际需求,本文提出了一种采用二进制文件存储地图数据的数据组织格式,此格式存储量小、显示速度快,并可与MIF数据相互转换。该数据格式已应用于邯郸物流车辆监控系统,跟其原有系统相比显示、查询速度加快,数据占有量大幅减少。

| Abstract: | Based on the principle of simpleness, universality, safety, easy transplant,this paper brings forward a user-defined data organization that using binary file to organize digital map data. This data organization requires small storage, can be quickly displayed, and also be converted to MIF data organization. Now, this data organization has been applied in HanDan Logistics Vehicle Monitoring System. Compared with the old system, this new system needs less storage and has higher speed of searching and displaying. |
