1. A map data transmission method comprising:
- determining a recommended route extending from a current position to a destination based upon map data that include road shape information indicating shapes of roads and road connection information indicating conditions with which the roads connect with one another;
extracting map data over a slicing range set within a predetermined distance from the determined recommended route from the map data;
making a decision as to whether or not the road connection information is to be eliminated from the extracted map data; and
transmitting map data obtained by eliminating the road connection information from the extracted map data if results of the decision indicate that the road connection information is to be eliminated.

Abstract
A preferred route from a present place to a destination in decided based on geographical data including road shape information indicative of the shapes of roads and also including road connection information indicative of connection conditions between the roads, and then geographical data of areas existing within a predetermined distance from the decided preferred route are derived. Then, it is decided whether the road connection information should be deleted from the derived geographic data, and if so decided, the geographic data are transmitted with the road connection information deleted.

8. A map data transmission method comprising:
-
determining a recommended route extending from a current position to a destination based upon map data that include road shape information indicating shapes of roads and road connection information indicating conditions with which the roads connect with one another;
extracting from the map data map data over a slicing range set within a predetermined distance from the determined recommended route;
making a decision as to whether or not part of the road shape information is to be eliminated from the extracted map data; and
transmitting map data obtained by eliminating part of the road shape information from the extracted map data if results of the decision indicate that part of the road shape information is to be eliminated. - View Dependent Claims (9, 10, 11, 12, 20)

15. A map data transmission method comprising:
-
determining a recommended route extending from a current position to a destination based upon map data that include road map data, which contain road shape information indicating shapes of roads and road connection information indicating condition with which the roads connect with one another, and facility data;
extracting road map data over a slicing range set within a predetermined distance from the determined recommended route and also extracting facility data of a facility satisfying a specific requirement from facility data in an area beyond the slicing range based upon the map data; and
transmitting, at least, the road map data extracted over the slicing range, the facility data extracted beyond the slicing range and map data corresponding to a road connecting with the facility. - View Dependent Claims (16, 17, 18, 19)
