MOBILE APPARATUS AND METHOD FOR DOWNLOADING OF MAP
First Claim
1. A method for downloading a map by a mobile apparatus connected to a map server, the method comprising the following steps of:
- (A) determining a present location of the mobile apparatus;
(B) determining a pre-set distance;
(C) determining a first map information and a second map information according to the pre-set distance, wherein the first map information completely corresponds to map information with a coverage centered at the present location and with a radius of the pre-set distance, and the second map information corresponds to map information outside the coverage centered at the present location; and
(D) downloading a map data comprising at least the first map information.

Abstract
The invention provides a method for downloading of maps for a mobile apparatus connected to a map server. Furthermore, the method of the invention includes four major steps. First of all, determine a present location of the mobile apparatus. Subsequently, determine a pre-set distance. Then, determine a first map information and a second map information according to the pre-set distance. Particularly, the first map information completely corresponds to map information with a coverage centered at the present location and with a radius of the pre-set distance, whereas the second map information corresponds to map information outside the coverage centered at the present location. Finally, download a map data which includes at least the first map information. By the method of the invention, user can selectively download maps in accordance with the needs of the user and the system environment.
