Abstract

Abstract A navigation apparatus includes a road data memory (16) for storing therein road data of position and shape data at every road, a road map making device (14) for making road map data by reading road data of a predetermined scope from the memory device (16), a route selecting device (14) for selecting a route on a road indicated by road map data for destination, and a video signal generating device (17) for generating a video signal for displaying a road map under the condition that symbols indicating the route selected by the route selecting device (14) are superimposed upon the road map data made by the road map making device (14), wherein shape data of minor roads existing at an intersecting point of roads are used as road data stored in the memory (16). The navigation apparatus can display a route at a crossing of complicated shape more accurately in conformity with the actual route.
