Abstract
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.

15. A navigation device for a movable object, comprising:
-
a data provider to provide data of a three-dimensional navigation map having one or more towering map objects; and a processor to receive data of a three-dimensional navigation map from the data provider, the received data of an area surrounding an ascertained position of a movable object, and to generate a display signal of the three-dimensional navigation map for a display device; wherein the processor generates the display signal so that the navigation map is displayed as if viewed from a view position that is located above the navigation map and is a function of the ascertained position of the movable object, wherein the processor dynamically alters a height of at least one towering map object in the navigation map as a function of a distance of the towering map object to the view position. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

30. A method for generating a display signal for a navigation device for a movable object, the method comprising:
-
receiving data corresponding to a three-dimensional navigation map having at least one towering map object of an area surrounding a movable object based on an ascertained position of the movable object; and generating a display signal representing the navigation map, so that the navigation map is viewed from a view position that is located above the navigation map and is a function of the ascertained position of the movable object, and a height of at least one towering object in the navigation map is altered dynamically as a function of a distance of the towering object to the view position; and transmitting the display signal representing the navigation map to a display device for display of the navigation map.

31. A non-transitory computer readable medium including instructions which when executed on a programmable processor, induce the processor to carry out the steps of a method, the method comprising:
-
receiving data corresponding to a three-dimensional navigation map having at least one towering map object of an area surrounding a movable object based on an ascertained position of the movable object; and generating a display signal representing the navigation map, so that the navigation map is viewed from a view position that is located above the navigation map and is a function of the ascertained position of the movable object, and a height of at least one towering object in the navigation map is altered dynamically as a function of a distance of the towering object to the view position; and transmitting the display signal representing the navigation map to a display device for display of the navigation map.
