摘　　要：导航路网数据拓扑严格但位置精度较低、农村地区低级别道路密度小,基础测绘道路数据位置精度高但拓扑不严格、农村地区低级别路网密度高,两者各自有其优缺点,本文在实践基础上阐述了综合两者优点的数据融合技术流程以及相关工具产品,属于已经应用于实际生产的成果,丰富了天地图在线路径分析数据,增加了路径分析数据密度,对相关从业者,具有一定的借鉴和推广意义。The navigation network has strict data topology but low position precision, and the low road density in rural areas is small. The location precision of the basic surveying and mapping road data is high, the topology is not strict, and the low level road network density in rural areas is high. Both of them have their own advantages and disadvantages. In this paper, the data fusion technology flow and related tool products are expounded on the basis of practice. The results of actual production. To enrich Tianditu online path analysis data and add path analysis data density, it has a certain reference and promotion significance for related practitioners.
