A METHOD OF PROCESSING POSITIONING DATA

摘要

A method of processing positioning data to generate map data which comprises a plurality of navigable segments representing segments of a navigable route in the area covered by the map with each segment being arranged to have speed data associated therewith, the method comprising: i. classifying the speed data associated with at least some, and generally each, navigable segment having speed data associated therewith into a category of a classification having a plurality of categories into which the speed data can be classified according to a parameter of a navigable segment with which the speed data is associated; ii. generating a category average for each category within the classification; iii. assessing at least some, and generally each, navigable segment within the map data to determine whether there is speed data associated therewith; and iv. if there is no speed data associated with a navigable segment, using the category average, according to the parameter of the navigable segment being processed, as the speed data for the navigable segment being processed.
