<p>A map display device includes: a display control unit that displays, at a display monitor, meshes partitioning a map into equal parts assuming a predetermined areal size and a map for which one of a plurality of scaling factors can be selected, by superimposing the meshes on the map; a storage unit in which map data constituted with mesh data corresponding to the map partitioned into the meshes are stored; an input accepting unit that accepts an input; a detection unit that detects a specific mesh selected through input at the input accepting unit among the meshes displayed via the display control unit; a reception unit that receives from an external source mesh data corresponding to the mesh detected by the detection unit and; and an update unit that updates map data stored in the storage unit by using the mesh data received via the reception unit.</p> |
