ABSTRACT:
A navigation system for vehicles comprises a read device that reads planar map data from a recording medium which stores in memory planimetric map data of a road map, a current position detection device that detects the current position of the vehicle, a storage circuit that stores in memory function tables for converting positional coordinates of nodes included in a road map area around the detected current position to positional coordinates of nodes on a bird's-eye-view map obtained by looking down upon the road map in a specific direction, at a specific look-down angle and a specific aspect angle from a viewpoint set above the vicinity of the detected current position and a bird's-eye-view map display data preparation circuit that reads out data related to coordinate positions of nodes on the bird's-eye-view map by operating the conversion table with the coordinate positions of nodes on the road map and prepares bird's-eye-view map display data for displaying the bird's-eye-view map on the monitor based upon the data thus read out.
