Method and system for providing tile map service using solid compression

A server for providing a tile map service through a network, the server comprising:

• a map data storage device which stores digital map data, a plurality of tile map data generated from the digital map data, and solid-compressed map data compressed by solid compression from the plurality of tile map data;
• a solid-compressed map data generation device including a tile map data generation unit, which divides the digital map data stored in the map data storage device into a plurality of tile map data and stores the divided tile map data in the map data storage device, and a solid-compressed map data generation unit, which generates solid-compressed map data by compressing the plurality of tile map data stored in the map data storage device by solid compression and stores the generated solid-compressed map data in the map data storage device;
• and
• a solid-compressed map data providing device including a solid-compressed map data retrieval unit, which retrieves the generated solid-compressed map data from the map data storage device based on the map area information received from a client, and a solid-compressed map data transmission unit which reads the solid-compressed map data retrieved by the solid-compressed map data retrieval unit from the map data storage device and transmits the read data to the client.

A method for providing a tile map service through a network, the method comprising:

• generating and storing, by a server, a plurality of tile map data from digital map data;
• generating and storing, by the server, solid-compressed map data by compressing the plurality of tile map data by solid compression;
• transmitting, at a client, map area information of digital map data to be received and receiving, at the server, the map area information;
• retrieving, by the server, solid-compressed map data corresponding to the map area information;
• transmitting, by the server, the retrieved solid-compressed map data to the client;
• and
• decompressing, by the server, the received solid-compressed map data to be restored to a plurality of tile map data.
