Abstract:
A map distribution system that implements navigation using desired map data in which the degree of reliability of information about an object, such as a road or a facility, is taken into consideration is provided. A map distribution server 1a creates distribution data including difference map data and a reliance status showing the degree of reliability of the difference map data as a reply to edit request information about an edit request made by a user, and a map information terminal 3 receives the distribution data via a communication network 2 and performs navigation according to the reliance status included in the distribution data.
