Method of generating improved map data for use in navigation devices
First Claim
1. A method of organizing and distributing map correction data, comprising the steps of:
- receiving map correction data at a server from a plurality of navigation devices,validating said map correction data,categorizing said validated map correction data into at least one category based at least on a source of each received map correction,receiving a category selection at the server from at least one remote client device, anddistributing categorized map correction data, based on the received category selection, to said at least one client device.

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.
