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.

Method and system for providing tile map service using image fusion

The system according to the present invention includes a server including a map data storage device, which stores digital map data, a plurality of tile map data generated from the digital map data, and solid-compressed map data compressed by solid compression from the plurality of tile map data, a solid-compressed map data generation device, which generates the plurality of tile map data from the digital map data stored in the map data storage device, generates the solid-compressed map data by compressing the plurality of tile map data by solid compression, and stores the generated solid-compressed map data in the map data storage device, and a solid-compressed map data providing device, which transmits the solid-compressed map data to a client through a network in response to a request from the client. Therefore, it is possible to reduce the frequency of network access and the amount of data transmitted.
