Abstract

A system and method are provided, the system and method for providing a tile map related to a region having low data frequency or a region having same color property, by providing the tile map using not only national territorial information on land but also marine spatial information and dynamic sensing information.

Claims

1. A tile map generation apparatus comprising:

a layer set unit to add at least one layer including at least one of national spatial information, marine spatial information, and dynamic sensing information, to set a presentation order and presentation zoom level with respect to the at least one added layer, and to set presentation style information with respect to the at least one added layer;

a tiling set unit to set environmental parameters of tiling for generation of a tile map; and

a tile map generation control unit to select whether to express the at least one added layer and select at least one layer to be presented on the tile reduced scale, to select an object included in the tile region, and to generate image-based tile map data, vector-based tile map data, and extension additional data based on the selected object.

2. The tile map generation apparatus of claim 1, wherein the layer set unit sets a first presentation style with respect to at least one style selected from a line thickness, a background color, a foreground color, and a symbol of the at least one added layer, and a second presentation style with respect to at least one analysis function selected from a thematic analysis, a distribution map analysis, a statistical analysis, and a mining analysis.

3. The tile map generation apparatus of claim 1, wherein the tile set unit sets at least one of identification information, a tile region, a tile reduced scale section, a coordinate system, and a vector tile generation condition with respect to a tile map service.

4. The tile map generation apparatus of claim 1, wherein the tile map generation control unit comprises:

a layer check unit to check whether at least one layer is to be expressed, and select at least one layer presented on the tile reduced scale according to the presentation order;

an object select unit to select the object included in the tile region of the selected layer, and check a presentation state of the object according to a column attribute value; and

a tile map generation unit to determine presence of the selected object, and to match the extension additional data having the background color as tile color information with tile map identification information when the selected object is absent or generate the image-based tile map data and the vector-based tile map data by reflecting the set presentation style information when the select object is present.

5. The tile map generation apparatus of claim 4, wherein the tile map generation unit match the generated extension additional data with the tile map identification information and load a match result on a database (DB).

6. The tile map generation apparatus of claim 4, wherein the tile map generation unit generates image data in an N×

M times size, where N and M are natural numbers, with respect to a width and a length of the tile region in a memory device context (DC), based on the set presentation style information, and divides the image data into at least one tile map data.

7. The tile map generation apparatus of claim 6, wherein the tile map generation unit matches the tile map identification information with the extension additional data including the tile color information and loads a match result on a DB when the tile color information of the at least one tile map data corresponds to a single color.

8. The tile map generation apparatus of claim 4, wherein the tile map generation unit generates the vector-based tile map data when the at least one tile map data includes the dynamic sensing information.

9. The tile map generation apparatus of claim 4, wherein the tile map generation unit generates the vector-based tile map data by encoding and compressing geographical spatial information and attribute information.

10. The tile map generation apparatus of claim 1, wherein the tile map generation control unit generates the image-based tile map data, the vector-based tile map data, and the extension additional data, corresponding to an updated region, by comparing at least one existing layer with at least one updated layer.

11. A tile map providing server comprising:

a file storage unit to store tile map data including image-based tile map data, vector-based tile map data, and extension additional data;

a request analysis and response unit to analyze a map region information request received from a client, and transmit the tile map data corresponding to the analyzed map region information request to the client; and

a request processing unit to read the tile map data from the file storage unit in response to the analyzed map region information request, and process the tile map data.

12. The tile map providing server of claim 11, wherein the request processing unit processes image data corresponding to tile color information included in the extension additional data when the analyzed map region information request is related to a region including the extension additional data.

13. A tile map receiving client comprising:

a tile map request unit to transmit a map region information request to a server;

a tile map manage unit to control storage of tile map data including at least one of image-based tile map data, vector-based tile map data, and extension additional data;

a presentation unit to generate map the data by receiving the tile map data and merging at least one tile map data, and store the map data or provide the map data to the user.

14. A tile map providing system comprising:

a tile map providing server to store tile map data including image-based tile map data, vector-based tile map data, and extension additional data, and to analyze a map region information request received from a client so as to process the tile map data corresponding to the analyzed map region information request and transmit the processed tile map data to the client; and

a tile map receiving client to control storage of the tile map data received from the tile map providing server, to transmit the map region information request to the tile map providing server, and to generate map data by receiving the tile map data and merging at least one tile map data and store the map data or providing the map data to a user.

15. A tile map generation method comprising:

adding at least one layer which includes 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;

setting tiling for tiling for providing a tile map service;

selecting whether to express the at least one added layer and at least one layer to be presented on the tile reduced scale, and selecting an object included in the tile region; and

generating image-based tile map data, vector-based tile map data, and extension additional data based on the selected object.
