A true bearing is a type of bearing that indicates the direction of one point relative to another point on the Earth's surface, measured using true north as a reference point. It is expressed as an angle, measured in degrees, between a fixed reference direction (such as true north) and the direction of the point being observed.
True bearings are important for navigation, surveying, and other applications that require accurate direction-finding. They differ from magnetic bearings, which are measured relative to the Earth's magnetic field, and are subject to variation depending on the location and time. True bearings are more reliable and consistent, as they are based on the Earth's axis of rotation and do not change over time or location.
Compass bearing refers to the direction indicated by a compass, typically expressed in degrees from the north, using cardinal directions (e.g., N, E, S, W) or in a clockwise manner from 0° to 360°. True bearing, on the other hand, is measured in degrees from true north, which is the geographic North Pole, and does not account for magnetic declination. While compass bearings can vary due to magnetic variations, true bearings provide a consistent reference based on the Earth's geography. In navigation, true bearings are often preferred for accuracy, especially over long distances.
azimuth
When calculating a bearing, azimuthal notation refers to the angle of the bearing from North, measured clockwise. Quadrant notation takes the bearing from north or south with a change to west or east. For example, Quadrant notation: SE = Azimuth notation of 135 degrees.
True
A number that makes an equation true is its solution.
The definition of a true compass bearing - A true bearing is measured in relation to the fixed horizontal reference plane of True North, that is using the direction towards the geographic North Pole as a reference point.
To calculate the magnetic bearing, you would subtract the declination from the true bearing if the declination is east, or add the declination if the declination is west. In this case, since the declination is 8 degrees east, you would subtract the declination from the true bearing of 180 degrees. Magnetic bearing = True bearing - Declination Magnetic bearing = 180 degrees - 8 degrees Magnetic bearing = 172 degrees
compass bearing 271
True magnetic bearing is the angle measured clockwise from true north to a destination point. It takes into account the magnetic declination, which is the difference between true north and magnetic north at a specific location. This type of bearing is important for accurate navigation using a magnetic compass.
