Document Type and Number:
Japanese Patent JP4749594
Kind Code:
B2
Abstract:
It is an object of the invention to provide a method of transmitting position information of a digital map which can enhance matching precision on a receiving side. The invention provides a method of transmitting position information of a digital map in which a transmitting side transmits a vector shape on the digital map and a receiving side specifies the vector shape on a self-digital map by map matching, wherein the transmitting side selects a portion in which a plurality of candidate points are generated with difficulty during the map matching as an endpoint of the vector shape and transmits the vector shape having the endpoint in the portion to the receiving side. Mismatching on the receiving side can be prevented and the position information on the digital map can be transmitted accurately.
