THREE-DIMENSIONAL MAP DISPLAY DEVICE, THREE-DIMENSIONAL MAP DISPLAY METHOD AND COMPUTER PROGRAM

摘要

PROBLEM TO BE SOLVED: To easily grasp a correspondence relationship between a feature and characters while suppressing the damage of the reality of a three-dimensional map in the case of displaying the feature and characters indicating information on the feature on the three-dimensional map.SOLUTION: A terminal 10 includes: a transmission/reception part 12 for acquiring map data 22 for three-dimensionally displaying a feature, representative point position data 24 indicating the position of the two-dimensional representative point of the feature and character data 26 for displaying information on the feature from a map database 20; a feature image generation part 14 for generating a feature image in which the feature is three-dimensionally plotted; and a character display control part 16 for controlling the display of characters indicating the information on the feature on the feature image. The character display control part 16 is configured to display the characters above the feature in the feature image, and to display a shadow image indicating the shadow of the characters at a position corresponding to the representative point on the upper surface of the feature on the basis of the representative point position data 24.
