摘要： Map display systems, map data processing apparatuses, map display apparatuses, and map display methods for general navigation systems are provided. A map data processing section categorizes original three-dimensional map data into scene graph data representing a data structure of a three-dimensional map using a tree structure and rendering data for rendering an object included in the three-dimensional map and processes the scene graph data and the rendering data. A map data display section specifies a display area by referring to the scene graph data and reads and displays the rendering data in accordance with the specified display area.

摘要： Three-dimensional map data of drawing objects in respective division areas and distant view images in respective directions on map data, which are obtained when viewing is made from insides of the respective division areas, are held in a recording medium, three-dimensional map data of a drawing object for a near view positioned in a sight line direction at a point of interest is retrieved from the three-dimensional map data based on position information of the point of interest and sight line direction information, and is converted into a map image based on a perspective drawing method. A distant view image obtained in the sight line direction is retrieved from the distant view images held in the recording medium based on the position information of the point of interest and the sight line direction information, and the retrieved distant view image is overwritten with the map image for the near view to combine them.
