procedure for correction in a memory of an agricultural machine, for example, arbeitsrechners stored using a gps sensor recorded position coordinates of at least an one-dimensional object, which, for example, on the basis of drifteffekten on on the real position is moved.the process is characterized by two preferably perpendicular to each other and verschiebeoperationen stored position coordinates relative to the current position, with the first verschiebeoperationen due to location and / or bewegungsrichtungsdaten of working on the basis of the determined direction, preferably, is carried out.
