Method and device for differential height modification of the surface of the traffic area

A method of differential height adjustment of the surface of the traffic area, in which the surface of the traffic area before adjustment is measured and a digital model of the surface of the traffic area before adjustment is calculated, the design of the target surface of the traffic area after adjustment is determined, a differential height adjustment model is calculated from the height differences of these surfaces, during adjustment, the X, Y position of the right and left working parts of the working tool of the construction machine, which creates a new surface by modifying, or the X, Y position of the unmodified surface of the areas adjacent to the right and left working parts of the working tool, is determined and the appropriate target height adjustment Ft (X,Y) is determined from the differential model of the height adjustments from the unmodified surface of the traffic area, this information is transmitted to the control computer of the construction machine, which makes the necessary settings of the construction machine to achieve the required height of the modification and the cross slope of the modification, and data from a total station, arranged stationary outside the construction machine, is used to determine the X, Y position, and then the height of the adjustments Ft (X, Y) is determined from the differential model of the height adjustments, characterized in that data from a GNSS receiver arranged on the construction machine is additionally used to determine the X, Y position of the right and left working parts of the working tool of the construction machine, or the X,Y position of the unmodified surface of the areas adjacent to the right and left working parts of the working tool, wherein the X, Y coordinates from the GNSS receiver are used to automatically determine the orientation and position of the total station.
