Wind rose


THE wind rose or nautical pink is a drawing that appears on the compass dial, on maps, blueprints, mockups, etc.

The use of wind roses is extremely common in all old and current navigation systems. Its star-shaped design is for the sole purpose of making it easy to see with the vessel's swing.


Wind Rose or Nautical Rose

The rose of the wind arose from the need to indicate exactly a direction that even the intermediate points would not determine, for a minimal initial deviation becomes greater and greater as the distance increases.

It indicates the directions known as cardinal points (North (N), South (S), East (L), and West (O)), collateral points (northeast, southeast, southwest, and northwest), and subcolateral points. Through wind rose, we situate the represented space in relation to the Earth and its other spaces.

The Meaning of Cardinal Points

North (N) - Marks the direction of the geographic North Pole of the Earth. There are two synonyms: northern and boreal. The most important astronomical reference is the Polar Star.

South (S) - Marks the direction of the earth's geographic South Pole. There are two synonyms: southern and austral. The best known astronomical reference is the Southern Cross.

East (L) - The approximate reference is the "sunrise". As the earth rotates from west to east, one can see the source east. During the day, one gets the impression that the sun crosses the sky from east (where it rises) to west (where it sets), constituting the apparent movement of the sun. The best known synonym is the word east.

West (O) - The approximate reference is the "sunset". The most widespread synonym is the word west. The cardinal points are not sufficient to orient ourselves accurately on the surface of the earth and for this reason it is also necessary to use the collateral and subcolateral points, which lie between two cardinal points.

Side Points

NO / NW - between west and north there is the collateral point northwest.
SE / SW - between west and south there is the collateral point south-west.
IF - between east and south there is the collateral point southeast.
HUH - between east and north, there is the collateral point northeast.

Subcolateral Points

ENE: east-northeast
WHAT IF: east-southeast
SSE: south-southeast
NNE: North, Northeast
NNO/NNW: north-northwest
SSO/SSW: south-south east
OSO/WSW: west-southwest
ONO/Wnw: west-northwest
