In navigation and cartography, compass bearing points provide a basic aid in understanding directions. The traditional compass rose consists of four cardinal directions: north, east, south and west, each 90 degrees apart, as well as four cardinal directions: northeast, southeast, southwest and northwest. In some professional fields, the scope of the compass will be further subdivided.
The compass' bearing points provide the user with a tool to refer to specific directions without having to calculate or memorize specific degrees.
Compasses are designed in many different forms according to different needs. The most basic "Eight Wind Compass" contains eight main wind directions, while the "Sixteen Wind Compass" subdivides each main wind direction one by one to form sixteen and a half wind directions. These wind directions are extremely important for applications in navigation, meteorology and other disciplines.
The Eight Winds Compass contains four basic directions: north (N), east (E), south (S), and west (W), and four intermediate directions (NE, SE, SW, NW). The naming of these directions has similar rules in many languages. For example, English uses compound words to express this, while in the Chinese language, east-west directions tend to precede north-south directions.
By subdividing the eight winds in the middle, a sixteenth wind compass can be formed, including North North East (NNE), Northeast East (ENE), South East East (ESE) and other directions. This system provides more precision when navigating.
Before the modern three-digit directional method became common, most ships used a 32-point compass to describe direction. This system was further refined in the mid-18th century, resulting in the use of 128 directions. These trivial directions are crucial to the overall navigation of the foreign country and help improve the accuracy of navigation.
"In the U.S. Navy, the use of compass directions has strict regulations, and different traditions will appear in other countries."
The history of the compass can be traced back to the medieval Mediterranean, when sailors began to develop language-based compass systems to guide navigation. As navigation technology advanced, the use of compasses evolved, eventually leading to the modern navigation system.
In the Mediterranean region, sailors created a complete set of "eight wind compasses". The wind names of this system mainly come from Italian and are influenced by other Mediterranean languages. These names reflected the actual wind directions sailors encountered during their voyages at the time.
In China, early navigation texts developed 24 compass directions based on the earthly branches. Among them, the use of a double-needle compass further improves the accuracy of navigation, which is significantly different from the Western compass system.
While modern navigation technology has improved dramatically, traditional compass systems still play an important role in many cultures. Whether it is its impact on maritime navigation or its contribution to geographical understanding, the use of the compass cannot be ignored. Against this background, we can’t help but think: With the advancement of technology, what role can traditional tools still play in our lives?
