A 3D map representing a feature that cannot be visually recognized such as an underground structure is displayed without a sense of discomfort. Among features stored in the map database, underground structures such as tunnels are classified into transmissive objects, and other features into non-transmissive objects. Then, the transmissive objects and the non-transmissive objects are projected individually so as to generate a transmissive object projection view and a non-transmissive object projection view. The transmissive object projection view thus obtained is superposed on the non-transmissive object projection view with adjusted transmittance. Making the transmissive objects to be transmissive and superposing them enables to realize a map that appears to the user as if a ground surface or features which blocked the transmissive objects are made to be transmissive whereby the transmissive objects become visible.
A three-dimensional (3D) map display system for displaying a 3D map representing a feature three-dimensionally, the system comprising:
A three-dimensional (3D) map display method for displaying a 3D map representing a feature three-dimensionally, executed by a computer, the method comprising the steps of:
A non-transitory computer-readable media with an executable computer program stored thereon, wherein the computer program instructs a computer to display a three-dimensional (3D) map representing a feature three-dimensionally, the computer program causing the computer to execute the steps of:
