摘要:
The system according to the present invention includes a server including 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 a client through a network in response to a request from the client. Therefore, it is possible to reduce the frequency of network access and the amount of data transmitted.
