Abstract
A navigation system is provided that includes a storage unit, a processing unit, and an optical output unit. The storage unit includes a first storage portion for storing type definition data for a plurality of object types, the type definition data defining a graphical representation of an object type in terms of at least one basic geometrical shape. A second storage portion includes object data for a plurality of objects, the object data for an object comprising object type data specifying an object type of the object and object position data specifying an object position of the object. To display an object having a specific object type, the processing unit reads the type definition data of the corresponding object type from the first storage portion and generates graphical representations of the basic geometrical shapes that constitute the object type on the optical output unit.
