    Abstract: In one embodiment, a method for road geometry matching with componentized junction models is provided. The method includes receiving a plurality of predefined road component models, receiving map data representing a physical road junction, selecting a subset of the plurality of road component models to characterize the physical road junction represented by the received map data, and defining a road junction configuration for the physical road junction with the selected road component models.

    Abstract: Based on map information acquired from a map DB, a viewpoint for viewing a ground surface on a map of a set region at a time of displaying the map is set. Altitude information that indicates an altitude of a landform present in at least a partial region of the set region is stored. In a case where the altitude information is present in the map DB at a position on the map, which is set in response to a position indicated by inputted position information, a sight direction of the viewpoint is changed, and the viewpoint is thereby set at a position higher than the altitude of the landform, which is indicated by altitude information of the position on the map. A display data for displaying, on a display device, a map in a case of viewing the ground surface from the viewpoint set is generated.

    Abstract: A method of operating a navigation apparatus is provided. A calculated route is shown on a map display of the apparatus together with a current position indication. In one embodiment, a maximum map scale is determined which will result in a representation of the entire remainder of the route being shown within a visible map display area during travel along the route. In another embodiment, a map scale is set, and the map display is then controlled to maximize the amount of the remainder of the route which is shown within a visible map display area for the given map scale during travel along the route.

    Abstract: Some embodiments of the invention provide a navigation application that allows a user to peek ahead or behind during a turn-by-turn navigation presentation that the application provides while tracking a device (e.g., a mobile device, a vehicle, etc.) traversal of a physical route. As the device traverses along the physical route, the navigation application generates a navigation presentation that shows a representation of the device on a map traversing along a virtual route that represents the physical route on the map. While providing the navigation presentation, the navigation application can receive user input to look ahead or behind along the virtual route. Based on the user input, the navigation application moves the navigation presentation to show locations on the virtual route that are ahead or behind the displayed current location of the device on the virtual route. This movement can cause the device representation to no longer be visible in the navigation presentation. Also, the virtual route often includes several turns, and the peek ahead or behind movement of the navigation presentation passes the presentation through one or more of these turns. In some embodiments, the map can be defined presented as a two-dimensional (2D) or a three-dimensional (3D) scene.

    Abstract: In a method of generating a database for use in outputting three- dimensional maps, a projection of a two-dimensional road vector onto a three-dimensional surface defined by digital terrain model data is determined. At least one three-dimensional road vector (94, 95, 98, 99) is determined based on the established projection and is stored in the database. The database is generated before it is deployed to a navigation device for use in outputting three-dimensional maps. A method of outputting three-dimensional maps and a navigation device may use the thus generated database.
