Abstract
A method and apparatus are disclosed for generating a display image including a map view and route information, the map view being a three dimensional perspective elevation view. In at least one embodiment, the method includes: determining, from height information associated with a map object to be displayed in the display image, whether the object obscures a line of sight to the route information in the three dimensional perspective elevation; and displaying the map object in a format that is dependent on whether the map object is determined to obscure the line of sight.

A method of generating a display image including a map view and route information, the map view being a three dimensional perspective elevation view, the method comprising:
- determining, from height information associated with a map object to be displayed in the display image, whether the object obscures a line of sight to the route information in the three dimensional perspective elevation;
- and
- displaying the map object in an at least partly transparent format that is dependent on whether the map object is determined to obscure the line of sight, wherein the display smoothly using a variable transparency parameter associated with the map object.
Route navigation apparatus configured to generate a display image comprising a three-dimensional perspective elevation map view superposed with route information, the apparatus comprising:
- a display device to display a three-dimensional map object in an at least partly transparent format that is dependent on whether the map object is determined to obstruct a line of sight to the route information in the map view, wherein the display device smoothly using a variable transparency parameter associated with the map object.
