Abstract: A geodetic levelling staff, a method for measuring a height with the geodetic levelling staff and a system including the geodetic levelling staff and a level are provided. The geodetic levelling staff includes a circular level that indicates whether the geodetic levelling staff is in a vertical position, a level detection unit for detecting a bubble position of the circular level, a control circuit that receives detected data performed by the level detection unit and transmits the detected data to a near field communication tool, the near field communication tool for performing a communication from the geodetic levelling staff to the level according to the detected data received from the control circuit, wherein the level operates according to the detected data received from the near field communication tool.
