Patent ID: 8553999

Claim:
A system for providing a tile map service using solid compression, the system comprising a server and a client which receives a tile map service from the server through a network, wherein the server comprises 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, which generates the plurality of tile map data from the digital map data stored in the map data storage device, generates the solid-compressed map data by compressing the plurality of tile map data 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, which transmits the solid-compressed map data to the client through the network in response to a request from the client, and wherein the client comprises a solid-compressed map data restoration device which provides map area information of digital map data to be received to the solid-compressed map data providing device of the server, receives solid-compressed map data corresponding to the map area information from the solid-compressed map data providing device of the server, and decompresses the received solid-compressed map data to be restored to a plurality of tile map data.
