A marking composition is laid on ground to provide a mark (16, 17) which is followed by agricultural equipment (10). The mark is coloured blue and sighted by CCD camera (20). The camera output is processed line by line in segments with pixels examined by an algorithm which determines which segment was the blue line. An indicator can signal position to an operator.
