Title: Method and system for transferring positional information of digital map
Inventor: ADACHI SHINYA
IPC: G08G1/0969
Filed: 2001-04-27
Abstract: PROBLEM TO BE SOLVED: To provide a method for transferring positional information of a digital map, which can accurately and effectively transfer the position on the digital map to a receiving side. SOLUTION: The method for transferring positional information of the digital map employs a transmitting side that transfers a vector form on the digital map and the receiving side that specifies the vector form on an own digital map using a map matching process. The transmitting side sets an allowable error (a) using a unit of nodes contained in the vector form, and approximates a portion or whole of the vector form to a function so as to meet the allowable error and transfers the vector form by using the function to the receiving side. The allowable error is closely set, and thereby the amount of transmitted data can be reduced without lowering the accuracy of matching at the receiving side, and the positional information of the digital map can be transferred accurately and effectively.
