Title: Method of transmitting position information of digital map
Inventor: ADACHI SHINYA
IPC: G09B29/10
Filed: 2002-04-25
Abstract: A digital map position information transfer method capable of improving the matching accuracy at a reception side. A digital map position information transfer method in which a transmission side transmits a vector shape on a digital map and a reception side identifies the vector shape on its digital map by map-matching. The transmission side selects as an end point of the vector shape a point where a plurality of candidate points will not be easily caused upon map matching and transmits the vector shape having the end point at the selected point to the reception side. This prevents erroneous matching at the reception side and accurately transfers information on the position on the digital map.
