A navigation device for a movable object includes a data provider and a processor that provides a three-dimensional navigation map having towering map objects. Based on an ascertained position of a movable object, the processor receives a three-dimensional navigation map having towering map objects of an area surrounding the movable object and provides navigation map to a display device so that the navigation map is reproducible by the display device in a manner viewed from a view position which is located above the navigation map and is a function of the ascertained position of the movable object. The processor dynamically alters a height of a towering map object in the navigation map as a function of a distance of the towering map object to the view position.
