13. A method for assisting an operator of a working machine using an information system, the working machine comprising a user operable implement, the information system comprising an illumination arrangement arranged to project an image onto a physical ground surface located within an area externally of the working machine and a control unit adapted to control the illumination arrangement, wherein the method comprises:
receiving, at the control unit, construction data of a portion of a surrounding of the working machine including the area externally of the working machine,
forming, by the control unit, the image to be projected based on the construction data, the construction data comprising information indicative of a construction situation below the ground surface,
receiving, at the control unit, information of a present location and orientation of the working machine, and
projecting, using the illumination arrangement, the image onto the surface based on the present location and orientation of the working machine using the illumination arrangement to assist the user in operating the implement relative to the construction situation below the ground surface, wherein the illumination arrangement comprises an image projector,
wherein the control unit is further adapted to control an orientation of the illumination arrangement in relation to the working machine and the ground surface, whereby the projected image at the ground surface is made independent on a present location and orientation of the working machine.
