Abstract
A method and apparatus for use with a mobile body navigation system are provided for reducing an amount of position data, expressing successive positions along a route that has been traversed by a mobile body, which are recorded by a data recording section to subsequently provide a route display or are transmitted by radio by a data transmitting section. A position recording judgement section uses one or more judgement criteria to obtain an indication of the degree of accuracy of each of the vehicle positions that are calculated by the navigation system, and enables recording or transmission of only those data that express positions for which the judgement criteria indicate that the corresponding degree of accuracy is sufficiently high.
