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. |
