A navigator's tool is an instrument used for orientation and navigation that shows direction relative to the geographic cardinal points. A diagram called a compass rose usually shows the directions north, south, east, and west on the compass face as abbreviated initials. When in use, the rose can be aligned with the corresponding geographic directions; for example, the N mark on the rose points northward. Many navigational tools display markings for angles in degrees in addition to (or sometimes instead of) the rose. North corresponds to 0°, and the angles increase clockwise, so east is 90°, south is 180°, and west is 270°. These numbers allow the tool to show magnetic north azimuths or true north azimuths or bearings, which are commonly stated in this notation. If magnetic declination between the magnetic north and true north at latitude angle and longitude angle is known, then direction of magnetic north also gives direction of true north.
