A compass rose or compass star, sometimes called a wind rose or rose of the winds, is a polar diagram displaying the orientation of the cardinal directions (north, east, south, and west) and their intermediate points. It is used on compasses (including magnetic ones), maps (such as compass rose networks), or monuments.
32-point compass rose. The points of the compass are a set of horizontal, radially arrayed compass directions (or azimuths) used in navigation and cartography.A compass rose is primarily composed of four cardinal directions—north, east, south, and west—each separated by 90 degrees, and secondarily divided by four ordinal (intercardinal) directions—northeast, southeast, southwest, and ...
Direction determination refers to the ways in which a cardinal direction or compass point can be determined in navigation and wayfinding.The most direct method is using a compass (magnetic compass or gyrocompass), but indirect methods exist, based on the Sun path (unaided or by using a watch or sundial), the stars, and satellite navigation.
A modern military compass, with included sight device for aligning. A compass is a device that shows the cardinal directions used for navigation and geographic orientation. It commonly consists of a magnetized needle or other element, such as a compass card or compass rose, which can pivot to align itself with magnetic north.
Song dynasty figurine of a man holding a compass. The compass is a magnetometer used for navigation and orientation that shows direction in regards to the geographic cardinal points. The structure of a compass consists of the compass rose, which displays the four main directions on it: East (E), South (S), West (W) and North (N). The angle ...
A modern nautical compass rose. The outer circle (true rose) is aligned with true north; the inner circle (magnetic rose) with magnetic north. Inside the magnetic rose there is also an older 32-point graduation. Date: 15 August 2007: Source: Redrawn in Inkscape; based on a public domain file created by NOAA. Author: Mysid
So drawn on a compass rose, Aristotle's explanation yields four parallels: Compass winds in Aristotle (30° angles) (1) the "ever-visible circle", i.e. the Arctic Circle, the boundaries of the circumpolar stars (stars which do not set) [43] connecting half-winds IK), (2) the summer solstice (connecting EZ), (3) the equinox (connecting AB)
For those troubled by the high art of manipulating numbers, there was an alternative. This was the visual device known as the "circle and square" (tondo e quadro), also supplied by Andrea Bianco in his 1436 atlas. [26] The circle was a 32-wind compass rose (or gathering of rhumb-lines). The circle was inscribed with an 8 × 8 square grid.
