Abstract: A tile map service (TMS) device and method are provided. The TMS device includes a storage configured to store map layers that have different map types, map data of an image tile form having a level of detail (LOD) structure of each of the map layers, and a tile map in which image tile maps of a plurality of map layers are merged; a communicator configured to receive map request information including two or more map types, an LOD level, and arbitrary map coordinates from a client; and a provider configured to provide a tile map corresponding to the map request information to the client.

Abstract: A method of visualizing an image, a device and a system using the same. The method of visualizing, by a device operatively connected with an image provision server, an image configured in a hierarchical structure including a plurality of levels includes receiving tile visualization information in an encoded form from the image provision server, the tile visualization information including a tile visualization type determined according to whether at least one tile belonging to each of the levels of the image includes data; decoding the encoded tile visualization information and obtaining the tile visualization information; making a request to the image providing server for data for a target level and tile, which are to be visualized according to the tile visualization information; and displaying an image, which is to be visualized, received from the image provision server.
