Further, when the reaching distance of the laser light is shorter than the surveying distance, the reference laser light emitter 20 is brought closer to the surveying vehicle 30 again,
After the readjustment of the difference between the moving distance and the height of the survey carriage 30 (and the laser receiver 31) and the levelness of the laser beam, the survey is started. When it continues, the above operation is repeated.
