Abstract
A method and apparatus for a navigation system for selecting a location on a three-dimensional map view has a pyramid cursor that identifies a focused location and a means to change a viewing angle. The three-dimensional map view shows the three-dimensional image of roads and flat surfaces but not buildings or other structures erected on the surfaces. The three-dimensional image of the building and other structure only within the area of the pyramid icon will be displayed on the screen. The navigation system allows the user to change the viewing angle of the three-dimensional view up to a top view so that a user can select a particular location on the top view.
