Method of generating improved map data for use in navigation devices, map data and navigation device therefor
First Claim
1. A method of generating improved map data for use in an electronic navigation device, the method comprising:
- displaying map data, suitable for route guidance algorithms, on a display of the electronic navigation device;
receiving a first input from a user on a user interface of the electronic navigation device to create a correction to an error in the map data, wherein the electronic navigation device is able to use the created correction without external processing of the correction;
downloading to the electronic navigation device a correction to another error in the map data input by another user;
receiving a second input from the user on the user interface to include or exclude from route calculations at least one of said created correction and said downloaded correction, and calculating a route to a destination based at least on said received second input.

Abstract
In one embodiment of the present invention, an end-user can input a correction to a map error, directly on the device. The device is then able to use the correction without external processing of the correction. Hence, it is no longer necessary for an end-user to simply report errors to the map vendor over a web link, then wait for that map vendor to verify the error, update its maps and finally supply the end-user with updates—a cycle that can take months and sometimes years to complete. Instead, the navigation device can use the correction immediately. End-users can also share corrections with other end-users and also with a shared remote server that aggregates, validates and distributes corrections.

13. An electronic navigation device, comprising:
-
a display; an input device; and a processor arranged to; display map data on the display; create a correction to an error in the map data in response to receiving a first input from a user on the input device, wherein the electronic navigation device is able to use the received correction without external processing of the correction; download a correction to another error in the map data input by another user; and calculate a route to a destination based at least on a second input received from the user on the input device to include or exclude from route calculations at least one of said received correction and said downloaded correction. - View Dependent Claims (14, 15, 16)
