• and
• a database for storing information of laying positions of the respective markers, wherein
• the laying position identifying part is configured to identify the position relation of the laying position of the respective marker with respect to the reference position based on a distance to the installation device measured by the surveying device by taking the installation device performing the operation for laying the respective marker as a target, and to identify a position, which has the position relation identified with respect to the reference position, as the laying position of the respective marker,
• the database is configured to store the laying position of the respective markers, and to accumulate the stored laying position of the respective markers as laying information of the plurality of markers.
