A system and method for processing a 3-dimensional landmark providing a 3-dimensional representation of a 3-dimensional real world object located at a predefined geographic location is provided. The method includes the steps of providing a data set containing the 3-dimensional landmark, determining a largest continuous horizontal surface of the 3-dimensional landmark, and storing the determined largest horizontal surface as road traffic area of a road network used by a user when moving on the object.

A navigation system has a database which stores index data for, respectively, a tile of a tiling. The index data includes, for each one of plural cells of a grid which is superimposed on the tile, respectively an identifier for each triangular face of a triangulated irregular network which at least partially overlaps with the respective cell. The plural cells of the grid are defined so as to cover the respective tile. A processing device of the navigation system is configured to use the index data to determine a triangular face on which a map feature having given lateral coordinates is located, in order to determine a height coordinate of the map feature.

Techniques for displaying a 3d map view of a 3d geographical map are provided. A database stores data which defines the 3d geographical map in a layered hierarchy comprising data layers which can be individually rendered for the 3d map view. The database comprises a data layer of a digital terrain model which is modelling a terrain surface and a data layer of a 3d road network comprising 3d road elements. A processor is configured for selecting specific data layers of the database in response to a resolution setting of the 3d map view and to render the 3d map view using the selected specific data layer.

Map viewer and method

A vehicle navigation system has a processing device. The processing device receives entries in a first data structure that are generated and are respectively associated with one tile of a tiling. The processing device may compare a three-dimensional terrain on the respective tile with at least one pre-defined tile pattern. Either an identifier for a pre-defined tile pattern or data describing the terrain on the respective tile may be stored by the processing device in the entry.

A navigation system may use digital maps to represent cartographic features during guidance along a route to a destination requested by a user. A system and method are provided for management of icons used to represent the cartographic features by storing data for multiple icons in a data array representing an image containing the plurality of icons.

A database for a navigation system has digital elevation model data defining a three-dimensional surface. The database stores, for plural tiles of a tiling, a first array including three-dimensional coordinates of vertices of plural triangulated irregular networks, TINs, for the respective tile, and a plurality of second arrays. Each second array respectively defines triangular faces of a TIN and includes a plurality of vertex indices of the vertices to define triangular faces of the respective TIN. A method of outputting a three-dimensional representation of a terrain and a method of generating the database are also described.

A navigation device for a vehicle comprises a database storing, for a plurality of tiles of a tiling, at least one triangulated irregular network (TIN) defining a three-dimensional surface, and, for a plurality of triangular faces of the at least one TIN, control information defining a nested bounding sphere for the respective triangular faces. The navigation device comprises a processor coupled to the database configured to calculate a screen-space error for the plurality of triangular faces based on the respective control information and based on at least one of the following: a viewing angle of an electronic map view, a virtual camera position of the electronic map view. The processor is configured to predict whether a triangular face is visible in the electronic map view based on the calculated screen-space error.

A navigation system may display a segment of a digital map including a map element and a label corresponding to the map element. A portion of the digital map where no labeling shall occur may be determined based on coordinate values of the map element. The label may be displayed such that the portion of the digital map where no labeling shall occur is not occupied by any portion of the label.
