Patent ID: 8670614

Claim:
A system for providing a tile map service using image fusion, the system comprising a server and a client which receives a tile map service from the server through a network, wherein the server comprises a map data storage device, which stores original tile map data, grayscale image tile map data generated from the original 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, which reads the original tile map data from the map data storage device, generates the grayscale image tile map data and the multi-resolution color image tile map data, and stores the generated data in the map data storage device, the server transmitting the grayscale image tile map data and color image tile map data having a resolution selected from the plurality of multi-resolution color image map data, wherein the client comprises a multi-resolution tile map data reception and fusion device which generates color tile map data having the resolution of the grayscale image tile map data by fusing the grayscale image tile map data and the color image tile map data, which are received through the network, and provides the color tile map data to a user, and wherein the resolution of the color image tile map data transmitted from the server is variably controlled by the client according to the network environment.
