<p>The present invention relates to a tile image updating system for applying an addition or a change of map source data to a tile image and, more particularly to a tile image updating system that updates tile images for a tile map service by applying the change of the map source data. The system may include: an information update managing unit that manages the information update of tile images which includes whether the tile image is updated correspondingly to the change of the source data; an image searching unit which extracts target tile images needing an update by searching tile images which are spatially overlapped with the change region of the source data; and an image updating unit that confirms whether the target update tile images are updated through data of the information update managing unit and which updates tile images which are not completed with the update by applying the change of the source data. Therefore, unnecessary processes which are repeated can be removed by managing the update information of each tile image, and furthermore, can reduce the resource use of the server and the processing speed.</p> |
