MAP INFORMATION PROCESSING DEVICE
First Claim
1. A map information processing device comprising:
- a map information storage unit for storing map information about a map in which a creation region is managed while being divided into meshes, the map information including both regional map files each of which is provided for an arbitrary region, and mesh management information for managing said meshes;
an update information acquiring unit for acquiring update information for updating the map information stored in said map information storage unit; and
a processor for updating each of the regional map files of the map information stored in said map information storage unit by using the update information acquired by said update information acquiring unit,wherein each of said regional map files stores mesh information which is map information about meshes including an arbitrary region corresponding to said each of said regional map files, said mesh management information includes mesh management records disposed in such a way as to respectively correspond to the meshes, each of said mesh management records includes file identifying information for identifying a regional map file including a corresponding mesh, version information about a version of the regional map file, and mesh storage location information showing a storage location of mesh information in the regional map file, and the file identifying information of a mesh management record corresponding to a mesh stored in a plurality of regional map files determines a latest version of a regional map file.
