GENERATING A DISPLAY IMAGE
First Claim
1. A method for generating a display image for a navigation device, wherein the display image includes a map view for display on the navigation device and the map view comprises a two dimensional plan view, the method comprising:
- identifying a plurality of map objects from a digital map for display in a display image on a navigation device;
determining whether any of said identified map objects include one or more non-visible features that would not be visible to a user of the navigation device at ground level;
generating an adapted set of map objects that does not include any of said non-visible features; and
generating from said adapted set of map objects, a simplified display image for display on the navigation device, wherein said simplified display image does not include any of said non-visible features.

Abstract
A method, computer program and apparatus are disclosed for generating a display image for a navigation device, wherein the display image includes a map view for display on the navigation device and the map view includes a two dimensional plan view. At least one embodiment of the method includes identifying a plurality of map objects from a digital map for display in a display image on a navigation device; determining whether any of the identified map objects include one or more non-visible features that would not be visible to a user of the navigation device at ground level; generating an adapted set of map objects that does not include any of the non-visible features; and generating, from the adapted set of map objects, a simplified display image for display on the navigation device, wherein the simplified display image does not include any of the non-visible features.

15. Route navigation apparatus configured to generate a display image comprising a two-dimensional plan map view, wherein the apparatus is configured to identify any non-visible features of said two-dimensional plan map view that would not be visible to a user of the navigation device at ground level, and to generate a simplified map view for display as said display image that does not include any said non-visible features.
