Abstract

A system and a method are provided that are capable of providing map data for supporting a variety of user network environments and selecting data zones freely. A navigation terminal includes a reception unit adapted to receive a file in which map data of a specific zone is stored, from a map provision server; and an execution unit adapted to execute a navigation function on the specific zone using the file. The file is produced by an individual unit with respect to each of geographic areas divided by a mesh unit having a variable size. The size of the mesh unit is decided according to the amount of information included in the geographic area such that the file has an equalized size.
