Claim Text:
1. A tile map generation apparatus comprising: a storage to store image-based tile map data, vector-based tile map data, and extension additional data; and a capable of performing operations comprising: a first operation of adding at least one layer including at least one of national spatial information, marine spatial information, and dynamic sensing information, setting a presentation order and presentation zoom level with respect to the at least one added layer, and setting presentation style information with respect to the at least one added layer; a second operation of setting environmental parameters of tiling for generation of a tile map; a third operation of determining whether to express the at least one added layer, selecting at least one layer to be presented at a tile scale level, selecting an object to be included in a tile region, and generating image-based tile map data, vector-based tile map data, and extension additional data based on the selected object, wherein the third operation includes generating the image-based tile map data, the vector-based tile map data, and the extension additional data, corresponding to the tile region, and wherein the vector-based tile map data is generated at a particular tile scale level only and wherein the third operation comprises: a first sub-operation of checking whether at least one layer is to be expressed, and selecting the at least one layer to be presented at the tile scale level according to the presentation order; a second sub-operation of selecting the object to be included in the tile region of the selected layer; and a third sub-operation of determining presence of the object, and linking the extension additional data having a background color as tile color information to tile map identification information when the object is absent or generating the image-based tile map data and the vector-based tile map data by reflecting the set presentation style information when the object is present.
