PURPOSE: A level information confirming system through precise leveling is provided to rapidly wipe a surface of a leveling rod and to remove dust on the surface of the leveling rod, thereby enabling a precise survey. . CONSTITUTION: A level information confirming system through precise leveling comprises a level measuring device and a level information collecting device(B). The level measuring device comprises a leveling rod installing device, a leveling rod, a distance measuring device(300), a transmitter(400), a leveler(500), and a level information collecting device(600). The leveling rod is detachably inserted into a leveling rod insertion hole of the leveling rod installing device and markings are marked on the circumference of the leveling rod. The distance measuring device is installed in a distance measuring installing hole of a leveling rod fixing device, thereby measuring a distance from a bottom surface of the leveling rod to a ground surface. The transmitter transmits a distance value of the distance measuring device. The lever confirms the markings on the leveling rod. The level measuring device comprises a storage unit(610) and a level information transmitting module(620). The level information collecting device comprises a receiving module, a level information data DB, and a display module.
