How are bearings typically described?

Bearings are typically described as degrees within a circle of 360 degrees, divided into four quadrants. This method provides a comprehensive way to indicate directions by specifying the angle relative to a base direction, which is typically north or south. Each bearing is represented as a combination of the cardinal direction (north or south) and the angle measured in degrees from the meridian, indicating both the specific direction and the associated quadrant.

For example, a bearing of 045 degrees indicates an angle measured east from north, while a bearing of 135 degrees indicates an angle measured south from east. This quadrant-based approach allows for easier navigation and positioning on maps and in the field, as it provides clear information about the direction of one point relative to another.

By contrast, using only cardinal directions, dividing the circle into eight sections, or expressing directions solely in decimal degrees lacks the precision and clarity offered by the quadrant system. These alternatives may not adequately represent specific angles or provide the necessary detail for surveying tasks, where precise direction is crucial.
