Kompassverdi

Kompassverdi, or compass value, is the numerical representation of the direction indicated by a compass. It is typically expressed in degrees relative to a reference direction, most commonly magnetic north, and is used to specify the heading or bearing of a person, vehicle, or device.

Reference frames: A magnetic kompassverdi corresponds to magnetic north; to obtain true heading you must apply magnetic declination for your location. Some devices report true north directly or allow switching between magnetic and true bearings.

Typical ranges: The most common convention is 0 to 360 degrees, with 0 (and 360) representing north, 90 east, 180 south, and 270 west. Some systems use -180 to 180 degrees. The terms bearing and azimuth are often used interchangeably with kompassverdi.

Measurement and accuracy: Kompassverdi can be measured with a physical compass or a digital magnetometer in smartphones and navigation devices. Accuracy is affected by tilt, magnetic interference from nearby metals or electronics, and environmental conditions. Calibration and, when possible, tilt compensation improve reliability.

Applications: Kompassverdi is used in navigation, orienteering, aviation, marine and land surveying, robotics, and geospatial mapping, as well as in augmented reality apps to align digital content with the physical world.
