PROBLEM TO BE SOLVED: To provide a navigation system capable of computing a distance depending on an actual moving situation considering positions and heights of facilities, entrances of buildings where the facilities exist, and a position of a moving means in a height direction.SOLUTION: The navigation system 10 has a facility information storage part 15 which memorizes information including positions and heights of facilities, entrances of buildings where the facilities exist, and a position of a moving means in a height direction and a current position detection part 18 which measures a current position, and computes distances from the current position to the facilities based on the current position, the positions and heights of the facilities, the entrances of buildings, and the position of the moving means in a height direction. Thereby the distance can be computed depending on the actual moving situation. |
