Abstract: Disclosed are an apparatus and method for configuring spatial information required to visualize a space represented based on a hierarchical structure having a plurality of levels each of which includes one or more tiles, configuring spatial information. The method includes checking tile visibility of each level according to whether a tile exists in the corresponding level; grouping one or more levels in which tile visibility is consistently maintained into one or more groups; and assigning a tile visibility index to each group.

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.
