The predetermined threshold may be set by the manufacturer of the navigation apparatus 100 before being released from the factory or may be set by the user according to the need of the user.The purpose of setting the predetermined threshold is to give margin of error for the positioning of the navigation apparatus 100.The navigation apparatus comprises a map database, a positioning module, a comparison module, and a map data adding module.The map database is configured to store data of a plurality of existed roads.And because may be viewed as the existed road that is nearest to the current position C.When the comparison module 120 determines that the coordinates P of the current position C of the navigation apparatus 100 is not on the plurality of existed roads, the map data adding module 130 may establish the traveling path 132 and determine if the shortest distance d between the plurality of existed roads and the coordinates P exceeds a predetermined threshold.The navigation apparatus 100 displays the existed road 144 in according to the piece of existed-road data 142.Furthermore, the positioning module 110 of the navigation apparatus 100 is configured to receive a positioning signal Sp to acquire coordinates P of a current location of the navigation apparatus 100.

illustrates a map displayed during navigation of the navigation apparatus 100.

The map data adding module is configured to establish a traveling path when the coordinates are not located on any one of the existed roads, and configured to update the traveling path according to succeeding coordinates of the navigation apparatus acquired by the positioning module while the shortest distance exceeds the predetermined threshold until the navigation apparatus return to any one of the existed roads.

The map data adding module stores data of the traveling path in the map database when the map data adding module finishes updating the traveling path.

In addition, the comparison module 120 of the navigation apparatus 100 is configured to determine if the coordinates P of the navigation apparatus 100 are located on anyone of the existed roads.

And when the coordinates P are not located on any one of the existed roads, the map data adding module 130 may establish a traveling path.
