    摘要: 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.

    摘要: 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.

    摘要: A navigation device comprises a processing device and a database. The database may store first data defining, for a plurality of objects, respectively a three-dimensional representation of the object. The database may store second data including, for at least a subset of the plurality of objects, an icon representation of the respective object, coordinates of the respective object and a pointer to a portion of the first data which is associated with the respective object. The processing device is coupled to the database and is configured to control an optical output device to display an object based on the first data or based on the second data.
