A method of transmitting position information of a digital map capable of transmitting a position on a digital map efficiently and accurately in which a transmitting side transmits position information including coordinate series information for specifying a vector shape on a digital map and a receiving side execute map matching by the coordinate series information to thereby identify the vector shape on the digital map, the coordinate series information is transmitted by adding azimuth information of a coordinate point included in the coordinate series information thereto. By transmitting shape data by adding the azimuth information thereto, accuracy of matching can be promoted and necessary time for matching can be shortened.
