Abstract
A map data providing method for providing map data to be used in a navigation system includes: dividing an area over which the map data are available into a plurality of blocks by using each of a plurality of division patterns set so that blocks resulting from divisions with the plurality of division patterns are not identical to one another; generating map data in correspondence to each of the blocks resulting from the divisions achieved with the plurality of division patterns; and providing the map data corresponding to the individual blocks resulting from the divisions achieved with the plurality of division patterns to a user so as to allow the user to freely select map data corresponding to any block.
