Azimuth compass
http://dbpedia.org/resource/Azimuth_compass an entity of type: Agent
An azimuth compass (or azimuthal compass) is a nautical instrument used to measure the magnetic azimuth, the angle of the arc on the horizon between the direction of the sun or some other celestial object and the magnetic north. This can be compared to the true azimuth obtained by astronomical observation to determine the magnetic declination, the amount by which the reading of a ship's compass must be adjusted to obtain an accurate reading. Azimuth compasses were important in the period before development of the reliable chronometers needed to determine a vessel's exact position from astronomical observations.

Un compas de relèvement est un compas de navigation sur lequel se superpose une alidade, qui permet de mesurer la direction d'un objet ou d'un astre, sur le plan horizontal, par rapport au nord. La quantité mesurée est donc un azimut. Cet angle est mesuré en degré de 000° à 359°, depuis le nord, dans le sens des aiguilles d'une montre (sens rétrograde).
