PURPOSE: A tile map service method using a solid compression method and system therefor are provided to reduce network access frequencies by restoring a plurality of map data using a solid pressure method. CONSTITUTION: A map data storage apparatus(110) stores digital map data, a plurality of tile map data, and solid pressure map data. A tile map data creation unit of a solid compression map data generation apparatus(120) allocates the digital map data to a plurality of tile map data. The solid compression map data generation unit of the solid compression map data creation apparatus creates solid compression map data by compressing a plurality of the tile map data. |
