===Azimuth=== 
{{main|Azimuth}}
The directional names are routinely associated with ''azimuths'', the [[angle of rotation]] (in [[degree (angle)|degrees]]) in the [[unit circle]] over the [[horizontal plane]]. It is a necessary step for [[navigation]]al calculations (derived from [[trigonometry]]) and for use with [[Global Positioning System]] (GPS) [[Receiver (radio)|receivers]]. The four cardinal directions correspond to the following degrees of a compass:
* North (N): 0° = 360°
* East (E): 90°
* South (S): 180°
* West (W): 270°

===Intercardinal directions===

The intercardinal (intermediate, or, historically, ordinal<ref>{{Cite web |url=https://www.geographyrealm.com/cardinal-directions-ordinal-directions/ |title="Ordinal directions refer to the direction found at the point equally between each cardinal direction," ''Cardinal Directions and Ordinal Directions'', geographyrealm.com |date=22 July 2013 |access-date=22 January 2025 }}</ref>) directions are the four intermediate compass directions located halfway between each pair of cardinal directions.
* Northeast (NE), 45°, halfway between north and east, is the opposite of southwest.
* Southeast (SE), 135°, halfway between south and east, is the opposite of northwest.
* Southwest (SW), 225°, halfway between south and west, is the opposite of northeast.
* Northwest (NW), 315°, halfway between north and west, is the opposite of southeast.

===Subintercardinal directions===

The eight above listed directional names have been further compounded known as '''secondary intercardinal directions''', resulting in a total of 16 named points evenly spaced around the compass. But there exist even '''tertiary intercardinal directions''', resulting in a total of 32 named points evenly spaced around the compass: north (N), north by east (NbE), north-northeast (NNE), northeast by north (NEbN), northeast (NE), northeast by east (NEbE), east-northeast (ENE), east by north (EbN), east (E), etc.
