    摘要: When transmitting an on-road location on a digital map, an information provider transmits, as on-road location information, string of coordinates information representing the road shape of a road section including the on-road location having a predetermined length, additional information including at least one information item chosen from a group of the attribute information on the road including the road location and detailed information on the nodes in the road section, and relative information indicating the on-road location in the road section. Receiving party receiving this on-road location information performs shape matching to identify the road section on a digital map and uses relative data to identify the on-road location in this road section. The receiving party can identify the road shape with high accuracy even when only a small amount of string of coordinates data is available. This makes it possible to reduce the data transmission amount and identify an on-load location with high accuracy.

    摘要: A system includes a transmitting apparatus having a first digital map and a receiving apparatus having a second digital map. The second digital map shows a road segment at a different location from the first digital map due to errors. The transmitting apparatus transmits location information to the receiving apparatus. The location information includes coordinates information, attribute information, and relative information. After receiving the location information from the transmitting apparatus, the receiving apparatus identifies the location of a road segment on the second digital map by using the coordinates information and the attribute information and identifies a location of a traffic event on the road segment on the second digital map by using the relative information. The relative information includes a distance from a start point of a road segment on the first digital map to the location on the road segment on the first digital map.
