1. A map display system having map data of three dimensions for displaying a three-dimensional map together with a representation of a vector map data comprising:
- an elevation acquisition means for acquiring an elevation of a route between a start point to an end point in said three-dimensional map;
a position determination means for determining a position of a guidance line in said three-dimensional map based on the elevation of the route; and
a map drawing means for drawing said three-dimensional map with the guidance line by using the position of the guidance line, wherein the guidance line represents the route in said three-dimensional map by using said vector map data.
