Abstract
A system includes a server including a map data storage device storing original tile map data, grayscale image tile map data, and a plurality of multi-resolution color image tile map data having a resolution lower than that of the grayscale image tile map data, and a multi-resolution tile map data generation and transmission device generating the grayscale image tile map data and the multi-resolution color image tile map data and storing the generated data in the map data storage device, and a client including a multi-resolution tile map data reception and fusion device generating color tile map data by fusing the received grayscale image tile map data and color image tile map data and providing the color tile map data to a user, in which the resolution of the color image tile map data transmitted from the server is variably controlled according to the network environment.
