POSITION INFORMATION TRANSMITTING METHOD AND DEVICE FOR DIGITAL MAP

WIPO Patent Application WO/2002/061374

A1

A position information transmitting method capable of transmitting a position on a digital map and a configuration accurately with a small amount of data despite a complicated road configuration, which allows a transmitter to send road configuration information for specifying a target road segment on a digital map and event information for specifying an event occurring position by a relative position in a target road segment, and allows a receiver to identify a target road segment on a digital map by map matching based on road configuration information and to specify an event occurring position in a target road segment based on event information, wherein the transmitter intermittently selects (2) nodes included in a target road segment to send the coordinates data of the nodes along with road configuration information, and the receiver determines (4) node positions included in road configuration information by map matching to obtain (5) a road portion between the nodes by route searching and identify a target road segment, thereby enabling us to send event positions on a digital map efficiently and accurately with a small amount of data.
