Digital map position information transfer method

The digital map data information transmission method, the method can enhance the receiving end of the matching of. The digital map data information transmission method, vector of the emitting terminal transmission digital map, the receiving end stipulates vector on the digital map by map match. The emitting terminal and the map match multiple produced in positions are as vector of difficultly the top, and transmits is connected with on the top of the vector) is transmitted to the receiving terminal. The separation with the matching device of receiving terminal, method and related digital map position information precisely.
