摘要: A method is provided for determining the vertical position of at least a point of a ground portion using a work machine including an implement. The work machine further includes a position determining arrangement adapted to determine at least the vertical position of the implement and a force determining arrangement adapted to determine a force applied to the implement. The method includes determining a contact force value indicative of a contact force between the ground portion and the implement using the force determining arrangement, determining whether or not the contact force value is within a predetermined contact force value range, and if it is determined that the contact force value is within the predetermined contact force value range, using the position determining arrangement for determining at least the vertical position of a portion of the implement which is in contact with the ground portion.
