Abstract
A storage device includes a map database having at least two specified sub-blocks and at least one non-specified sub-block. Each specified sub-block is correlated to a measurement position coordinate obtained from an external server by a measurement. The measurement position coordinate of each specified sub-block is stored in the storage device. The non-specified sub-block is directly or indirectly sandwiched by the two specified sub-blocks along a road. A measurement position coordinate of the non-specified sub-block is stored in the storage device when a distance between the measurement position coordinate and an estimation position coordinate of the non-specified sub-block is equal to or longer than a predetermined distance, and the measurement position coordinate of the non-specified sub-block is not stored in the storage device when the distance between the measurement position coordinate and the estimation position coordinate of the non-specified sub-block is shorter than the predetermined distance.
