Compass reading is a term used in navigation to refer to the direction indicated by a magnetic compass. The IPA phonetic transcription for compass reading is /ˈkʌmpəs ˈriːdɪŋ/. The initial syllable is pronounced with a short "u" sound, followed by a stress on the second syllable "puss". The final syllable is pronounced with a long "ee" sound, followed by a soft "ng" sound. This term is often used by sailors, hikers, and other outdoor enthusiasts to help them navigate using a compass.
Compass reading refers to the process of determining the direction or bearing using a compass. A compass is a navigational instrument that consists of a magnetized needle, typically marked with the cardinal points of north, south, east, and west, which aligns itself with the Earth's magnetic field.
When conducting a compass reading, one holds the compass flat and level, allowing the needle to move freely. The needle points towards the Earth's magnetic north pole, providing a reference to guide navigation. By aligning maps or charts with the compass reading, individuals can establish their geographical position and determine the desired direction of travel.
Compass readings are commonly used in various fields such as hiking, orienteering, sailing, and exploring unfamiliar areas. They aid individuals in keeping track of their course, helping them avoid getting lost and ensuring they reach their intended destination.
To obtain an accurate compass reading, it is crucial to consider navigational factors such as magnetic declination, which is the difference between true north and magnetic north. This numeric value varies depending on the individual's location on Earth, and it must be either added or subtracted from the compass reading to achieve the correct direction.
In summary, compass reading is the act of using a compass to determine direction and navigate accurately. It involves aligning maps or charts with the compass needle and considering variables like magnetic declination to achieve accuracy in one's bearings.
The word "compass" comes from the Latin term "circumpassus", which means "a circular course or circuit". The term entered English via the Old French word "compas", referring to a device used to draw circles. The word "reading" stems from the Old English word "rædan", which means "to advise, interpret, or explain". Therefore, the term "compass reading" combines the idea of using a compass to navigate or determine direction, and the act of interpreting or understanding the readings provided by the compass.
