摘要
A map data production method is disclosed. The method includes: dividing a record target map area into meshes; creating mesh-unit data elements as groups of mesh-unit data elements so that the groups respectively correspond to the meshes, and each group of mesh-unit data elements describes information on map components of a corresponding one of the meshes in such manner that mesh-unit data elements in the each group respectively describes the information on the map components; creating data files, through (i) organizing, according to map component type, the mesh-unit data elements into sets of mesh-unit data elements and (ii) respectively storing the sets of mesh-unit data elements, each set having a same map component type, in the data files; and creating map data from the plurality of data files.
