Abstract: A system for validating a correction to map data for a geographic location, the system comprising: a processing resource; and a navigation device; wherein the processing resource comprises: a user request generator that is configured to generate a user request for transmission to the navigation device; a transmitter for transmitting the generated user request to the navigation device; and a receiver for receiving a user response from said navigation device; and the navigation device comprises: a receiver for receiving the user request transmitted from the processing resource; a user request module configured to present said received user request to a user of the navigation device; a user response module for capturing a user response to said presented user request, and a transmitter for transmitting said captured user response to said processing resource.

Abstract: A navigation device includes: a route calculation module operable to calculate a route from a start location to a destination location; a rendering module configured to use digital map data to generate images of the route for display to a user; and a route preview module operable to provide the user with a preview of the calculated route. In at least one embodiment, the route preview module is operable to divide the calculated route into junction segments and road segments, and is configured to control the rendering module to display images representative of locations within the road segments at a higher display speed than images representative of locations within the junction segments.

Abstract: A technique is disclosed for calculating a sightseeing route from a start location to a destination location. The start location and the destination location may be the same as each other or different. The route is calculated to pass one or more attractors each representing a sightseeing attraction. A digital database resource (500) contains digital map information, the digital map information including a plurality of attractors. The technique comprises (a) determining (550) an initial route from the start location to the destination location, and setting the initial route as a current route; (b) determining (602) for each attractor in a candidate set of the attractors, a relative attraction value that is dependent on a distance between the attractor and the current route; (c) determining (604, 612) which attractor corresponds to a largest attraction value; (d) modifying (620) the current route to include a deviation to the attractor determined at step (c).
