Abstract
In a stereoscopic map display method for an on-vehicle navigation apparatus, in displaying a town map, a threshold value is changed in accordance with the display scale; buildings taller than the threshold value are displayed stereoscopically; and buildings shorter than the threshold value are displayed monoscopically. Furthermore, of the buildings displayed stereoscopically, buildings as tall as or taller than a particular height are displayed as opaque images while the other buildings are displayed as transparent or semitransparent images. Furthermore, in displaying the buildings taller than the threshold value, shadows may be drawn as the buildings are projected.
