    摘要: Systems, methods, and programs create a road map data structure, the data structure including road network data in which a road is represented by a plurality of links connected in a link string. The systems, methods, and programs assign a link ID to each of the links of the road network data. For each link, the link ID has a numerical range set in accordance with both a length of the link and a road attribute, and the link ID is set sequentially in a connection order within the link string.

    摘要: Map updating systems, methods, and programs create instruction data in a data center used for updating a pre-update piece of map structuring data among a plurality of pieces of stored map structuring data to a post-update piece of map structuring data, the instruction data identifying, in units of bytes, a portion of the pre-update piece of map structuring data to be updated and a post-update data content. The systems, methods, and programs then update the pre-update piece of map structuring data in a mobile device to the post-update piece of map structuring data according to the instruction data by updating, in units of bytes, the portion of the pre-update piece of map structuring data to be updated that has been identified by the instruction data so that the portion includes the post-update data content identified by the instruction data.
