1. A method of distributing map correction data, comprising:
- aggregating and categorizing, at a server, received public map corrections, wherein the categorization includes at least analyzing the received public map corrections in terms of the source from which the public map corrections were received, and assigning at least one source category to map corrections received from sources having a particular trustworthiness into a plurality of categories; and
distributing, by the server on request, categorized map corrections to a client.

Abstract
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.

14. A system for distributing map correction data, comprising:
-
a server configured to aggregate and categorize received public map corrections; a client from which public map corrections are received by said server, and to which categorized public map corrections are subsequently distributed, wherein the categorization performed by the server includes at least analyzing the received public map corrections in terms of the source from which they were received, and assigning at least one source category to those map corrections received from sources having a particular trustworthiness, and wherein the server, on request from a client, subsequently distributes categorized map corrections to that client. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
