NAVIGATION DEVICE, METHOD OF OUTPUTTING A MAP, AND METHOD OF GENERATING A DATABASE

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.
