A method and machine for generating map data and a method and navigation device for determining a route using map data

摘要

A kind of method, image data for creating the processing position data of image data includes multiple navigable parts, it indicates the part of a navigable route, its in the area cover by the figure in the case where each part is configured to have associated speed data, including method: i.That speed data of processing speed data classification enters associated for multiple set periods of the navigable part with which speed data; ii., in order to generate the velocity profile measured Mean Speed data within each set period for that navigable part.
