An opi­some­ter, also called a curvime­ter, meilo­graph, or map mea­sur­er, is an in­stru­ment for mea­sur­ing the lengths of ar­bi­trary curved lines. A simple opi­some­ter consists of a toothed wheel of known cir­cum­fer­ence on a handle. The wheel is placed in contact with the curved line to be measured and run along its length. The in­stru­ment is most commonly used to measure the lengths of roads, rivers and other line features on maps.
