<p>A method of marking a line includes providing a line marking apparatus including a body (21), a line marking head (29) movable relative to the body, and a positioning system (35, 37, 41, 43) for determining a geographical location of the line marking head. In addition, a mathematical model is provided for a line to be marked by the line marking head, the model being cumulatively updated in response to a position fix (61) obtained by the positioning system. The position of the line marking head is adjusted relative to the body in dependence upon the mathematical model.</p> |
