Direction determination refers to the ways in which a cardinal direction or compass point can be determined in navigation and wayfinding.The most direct method is using a compass (magnetic compass or gyrocompass), but indirect methods exist, based on the Sun path (unaided or by using a watch or sundial), the stars, and satellite navigation.
A compass is an instrument used for navigation and orientation that shows direction relative to the geographic cardinal directions (or points). Usually, a diagram called a compass rose shows the directions north, south, east, and west on the compass face as abbreviated initials.
32-point compass rose. The points of the compass are a set of horizontal, radially arrayed compass directions (or azimuths) used in navigation and cartography.A compass rose is primarily composed of four cardinal directions—north, east, south, and west—each separated by 90 degrees, and secondarily divided by four ordinal (intercardinal) directions—northeast, southeast, southwest, and ...
The four main compass bearings (North, East, South and West) are multiples of 90°: The advantage of three-figure bearings is that they describe any direction uniquely: Note that the last one has four figures (three in front of the decimal point and one after) but it is still a "three-figure bearing", the .4 just gives more accuracy.
The directions are at \(90°\) angles on the compass rose. The four ordinal directions are Northeast ( NE ), Southeast ( SE ), Southwest ( SW ) and Northwest ( NW ). They are halfway between the ...
Four Main Compass Directions (Cardinal Points): North (N) – This points to the North Pole and is usually shown at the top of maps. South (S) – Opposite to north, pointing towards the South Pole. East (E) – To the right of north; it’s the direction where the sun rises. West (W) – Opposite east, to the left of north, where the sun sets.

A bearing is a direction gotten from a compass with the quadrant scale (like N37W) while a direction from a compass with 0 - 360 is an azimuth. The term triangulation is incorrect: this technique is called resectioning and involves the intersection of any two linear features, which can be 2 compass directions but also a road and an elevation, etc.
