ABSTRACT:
A map data transmitting server, interconnected with a vehicle terminal through a wireless network, stores map data including a plurality of cell layers in which cells are linearly aligned, each cell of the cell layer bordering two adjacent cells of another cell layer that is adjacent to the cell layer, and the vehicle terminal selectively requests transmission of needed cell data to the server and accordingly receives the requested data from the server.
