发明名称 Method of generating improved map data for use in navigation devices
摘要 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.
