Generating a display image
First Claim
1. A method for generating a display image including a map view and a road adjoining a calculated route, the map view being a three dimensional perspective elevation view of a portion of a digital map as viewed from a viewing position, the method comprising:
- determining, from information associated with a distance of the road that is to be displayed in the display image from the viewing position, whether a map object obscures a line of sight from the viewing position to the road in the three dimensional perspective elevation; and
displaying an element of the road in a format that is dependent on the determination of whether the map object is determined to obscure the line of sight, wherein in response to determining that the map object obscures the line of sight, displaying the road element in a format that permits simultaneous viewing of the road element and map object, wherein the road element comprises a stub extending to encompass a part of the road that is obscured by said map object.

13. A non-transitory computer readable medium, comprising executable software which, when executed by a computer processor, implements a method for generating a display image including a map view and a road adjoining a calculated route, the map view being a three dimensional perspective elevation view of a portion of a digital map as viewed from a viewing position, the method comprising:
-
determining, from information associated with a distance of the road that is to be displayed in the display image from the viewing position, whether a map object obscures a line of sight from the viewing position to the road in the three dimensional perspective elevation; and displaying an element of the road in a format that is dependent on the determination of whether the map object is determined to obscure the line of sight, wherein in response to determining that the map object obscures the line of sight, displaying the road element in a format that permits simultaneous viewing of the road element and map object, wherein the road element comprises a stub extending to encompass a part of the road that is obscured by said map object. - View Dependent Claims (14)

15. Route navigation apparatus configured to generate a display image including a map view and a road adjoining a calculated route, the map view being a three dimensional perspective elevation view of a portion of a digital map as viewed from a viewing position, the apparatus comprising:
-
a processor to determine, from information associated with a distance of the road that is to be displayed in the display image from the viewing position, whether a map object obscures a line of sight from said viewing position to the road in the three dimensional perspective elevation; and a display to display an element of the road in a format that is dependent on whether the map object is determined to obscure the line of sight, wherein in response to determining that the map object obscures the line of sight, the display displays the road element in a format that permits simultaneous viewing of the road element and map object, wherein the road element comprises a stub extending to encompass a part of the road that is obscured by said map object. - View Dependent Claims (16)
