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 correction.
