<p>A method for transmitting information on a position on a digital map efficiently and correctly. The method includes a step of transmitting position information including coordinate series information for specifying the shape of a vector on a digital map from the transmission side, carrying out map matching using the coordinate series information on the reception side, and identifying the shape of the vector, wherein information on the orientation of the coordinate point included in the coordinate series information is added to the coordinate series information and transmitted together. Consequently, the matching accuracy is improved and the time required for the matching is shortened since the orientation information is added to the shape data and transmitted.</p> |
