Photo below: A sailor on the bridge of the nuclear-powered aircraft carrier uses a telescopic alidade. An alidade is an instrument used for determining direction, to take a bearing. An alidade allows one to sight a distant object and use the line of sight to perform a task. This task can be, for example, to draw a line on a plane table in the direction of the object or to measure the angle to the object from some reference point. Angles measured can be horizontal, vertical or in any chosen plane. The alidade's primary use is for creating maps in the horizontal plane.
