摘要： 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.

摘要： Disclosed is a system and method capable of minimizing user-set search data and local filtering data by creating index data in real time. A search data processing system includes an index generation unit adapted to generate index data for a search on map-associated data of an item selected by a user; and a search execution unit adapted to execute a search operation on the map-associated data of the selected item by means of the index data.
