West east north

Postby Faugor В» 25.01.2020

.

The four cardinal directions , or cardinal points , are the directions north , east , south , and west , commonly denoted by their initials N, E, S, and W. East and west are perpendicular at right angles to north and south, with east being in the clockwise direction of rotation from north and west being directly opposite east.

Points between the cardinal directions form the points of the compass. The intercardinal also called the intermediate directions and, historically, ordinal directions are northeast NE , southeast SE , southwest SW , and northwest NW. The intermediate direction of every set of intercardinal and cardinal direction is called a secondary intercardinal direction , the eight shortest points in the compass rose that is shown to the right e.

To keep to a bearing is not, in general, the same as going in a straight direction along a great circle. Conversely, one can keep to a great circle and the bearing may change. Thus the bearing of a straight path crossing the North Pole changes abruptly at the Pole from North to South.

When travelling East or West, it is only on the Equator that one can keep East or West and be going straight without the need to steer. Anywhere else, maintaining latitude requires a change in direction, requires steering. However, this change in direction becomes increasingly negligible as one moves to lower latitudes. The Earth has a magnetic field which is approximately aligned with its axis of rotation. A magnetic compass is a device that uses this field to determine the cardinal directions.

Magnetic compasses are widely used, but only moderately accurate. The north pole of the magnetic needle points towards the geographic north pole of the earth and vice versa. This is because the geographic north pole of the earth lies very close to the magnetic south pole of the earth.

This south magnetic pole of the earth located at an angle of 17 degrees to the geographic north pole attracts the north pole of the magnetic needle and vice versa. The position of the Sun in the sky can be used for orientation if the general time of day is known.

In the morning the Sun rises roughly in the east due east only on the equinoxes and tracks upwards. In the evening it sets in the west, again roughly and only due west exactly on the equinoxes. In the middle of the day, it is to the south for viewers in the Northern Hemisphere , who live north of the Tropic of Cancer, and the north for those in the Southern Hemisphere , who live south of the Tropic of Capricorn.

This method does not work very well when closer to the equator i. Conversely, at low latitudes in the southern hemisphere the sun may be to the south of the observer in summer. In these locations, one needs first to determine whether the sun is moving from east to west through north or south by watching its movements—left to right means it is going through south while the right to left means it is going through north; or one can watch the sun's shadows.

If they move clockwise, the sun will be in the south at midday, and if they move anticlockwise, then the sun will be in the north at midday. Because of the Earth's axial tilt , no matter what the location of the viewer, there are only two days each year when the sun rises precisely due east. These days are the equinoxes. On all other days, depending on the time of year, the sun rises either north or south of true east and sets north or south of true west.

For all locations, the sun is seen to rise north of east and set north of west from the Northward equinox to the Southward equinox , and rise south of east and set south of west from the Southward equinox to the Northward equinox.

There is a traditional method by which an analogue watch can be used to locate north and south. The Sun appears to move in the sky over a hour period while the hour hand of a hour clock dial takes twelve hours to complete one rotation.

In the northern hemisphere, if the watch is rotated so that the hour hand points toward the Sun, the point halfway between the hour hand and 12 o'clock will indicate south. For this method to work in the southern hemisphere, the 12 is pointed toward the Sun and the point halfway between the hour hand and 12 o'clock will indicate north.

During daylight saving time , the same method can be employed using 1 o'clock instead of The difference between local time and zone time, the equation of time , and near the tropics the non-uniform change of the Sun's azimuth at different times of day limit the accuracy of this method.

A portable sundial can be used as a more accurate instrument than a watch for determining the cardinal directions. Since the design of a sundial takes account of the latitude of the observer, it can be used at any latitude.

See: Sundial Using a sundial as a compass. Astronomy provides a method for finding direction at night. All the stars appear to lie on the imaginary Celestial sphere. Because of the rotation of the Earth, the Celestial Sphere appears to rotate around an axis passing through the North and South poles of the Earth.

This axis intersects the Celestial Sphere at the North and South Celestial poles , which appear to the observer to lie directly above due North and South respectively on the horizon.

In either hemisphere, observations of the night sky show that the visible stars appear to be moving in circular paths, caused by the rotation of the Earth. This is best seen in a long exposure photograph , which is obtained by locking the shutter open for most of the intensely dark part of a moonless night. The resulting photograph reveals a multitude of concentric arcs portions of perfect circles from which the exact center can be readily derived, and which corresponds to the Celestial pole , which lies directly above the position of the true pole North or South on the horizon.

A published photograph exposed for nearly 8 hours demonstrates this effect. The Northern Celestial pole is currently but not permanently within a fraction of 1 degree of the bright star Polaris.

The exact position of the pole changes over thousands of years because of the precession of the equinoxes. Polaris is also known as the North Star , and is generically called a pole star or lodestar. Polaris is only visible during fair weather at night to inhabitants of the Northern Hemisphere. The asterism " Big Dipper " may be used to find Polaris. The 2 corner stars of the "pan" those opposite from the handle point above the top of the "pan" to Polaris. While observers in the Northern hemisphere can use the star Polaris to determine the Northern celestial pole, the Octans constellation's South Star is hardly visible enough to use for navigation.

For this reason, the preferred alternative is to use the constellation Crux The Southern Cross. The southern celestial pole lies at the intersection of a the line along the long axis of crux i. At the very end of the 19th century, in response to the development of battleships with large traversable guns that affected magnetic compasses, and possibly to avoid the need to wait for fair weather at night to precisely verify one's alignment with true north , the gyrocompass was developed for shipboard use.

Since it finds true, rather than magnetic, north, it is immune to interference by local or shipboard magnetic fields. Its major disadvantage is that it depends on technology that many individuals might find too expensive to justify outside the context of a large commercial or military operation.

It also requires a continuous power supply for its motors, and that it can be allowed to sit in one location for a period of time while it properly aligns itself. Near the end of the 20th century, the advent of satellite-based Global Positioning Systems GPS provided yet another means for any individual to determine true north accurately.

The government agencies responsible for the satellites continuously monitor and adjust them to maintain their accurate alignment with the Earth. There are consumer versions of the receivers that are attractively priced.

Since there are no periodic access fees, or other licensing charges, they have become widely used. GPSR functionality is becoming more commonly added to other consumer devices such as mobile phones. Handheld GPSRs have modest power requirements, can be shut down as needed, and re calibrate within a couple of minutes of being restarted.

In contrast with the gyrocompass which is most accurate when stationary, the GPS receiver, if it has only one antenna, must be moving, typically at more than 0. On ships and aircraft, GPS receivers are often equipped with two or more antennas, separately attached to the vehicle.

The exact latitudes and longitudes of the antennas are determined, which allows the cardinal directions to be calculated relative to the structure of the vehicle. Within these limitations GPSRs are considered both accurate and reliable. The GPSR has thus become the fastest and most convenient way to obtain a verifiable alignment with the cardinal directions. The four cardinal directions correspond to the following degrees of a compass:.

The intercardinal intermediate, or, historically, ordinal [1] directions are the four intermediate compass directions located halfway between each pair of cardinal directions. With the cardinal points thus accurately defined, by convention cartographers draw standard maps with north N at the top , and east E at the right.

In turn, maps provide a systematic means to record where places are, and cardinal directions are the foundation of a structure for telling someone how to find those places. North does not have to be at the top. Most maps in medieval Europe , for example, placed east E at the top. In mathematics , cardinal directions or cardinal points are the six principal directions or points along the x-, y- and z- axis of three-dimensional space.

In the real world there are six cardinal directions not involved with geography that are north , south , east , west , up and down. In this context, up and down relate to elevation , altitude , or possibly depth if water is involved. The topographic map is a special case of cartography in which the elevation is indicated on the map, typically via contour lines. In astronomy , the cardinal points of an astronomical body as seen in the sky are four points defined by the directions towards which the celestial poles lie relative to the center of the disk of the object in the sky.

The North point will then be the point on the limb that is closest to the North celestial pole. Similarly, a line from the center to the South celestial pole will define the South point by its intersection with the limb. The points at right angles to the North and South points are the East and West points. Going around the disk clockwise from the North point, one encounters in order the West point, the South point, and then the East point.

This is opposite to the order on a terrestrial map because one is looking up instead of down. Similarly, when describing the location of one astronomical object relative to another, "north" means closer to the North celestial pole, "east" means at a higher right ascension , "south" means closer to the South celestial pole, and "west" means at a lower right ascension.

If one is looking at two stars that are below the North Star, for example, the one that is "east" will actually be further to the left.

During the Migration Period , the Germanic languages ' names for the cardinal directions entered the Romance languages , where they replaced the Latin names borealis or septentrionalis with north, australis or meridionalis with south, occidentalis with west and orientalis with east.

It is possible that some northern people used the Germanic names for the intermediate directions. Medieval Scandinavian orientation would thus have involved a 45 degree rotation of cardinal directions. In many regions of the world, prevalent winds change direction seasonally, and consequently many cultures associate specific named winds with cardinal and intercardinal directions.

For example, classical Greek culture characterized these winds as Anemoi. In pre-modern Europe more generally, between eight and 32 points of the compass — cardinal and intercardinal subdirections — were given names.

These often corresponded to the directional winds of the Mediterranean Sea for example, southeast was linked to the Sirocco , a wind from the Sahara. Particular colors are associated in some traditions with the cardinal points. These are typically " natural colors " of human perception rather than optical primary colors. Many cultures, especially in Asia , include the center as a fifth cardinal point.

Central Asian , Eastern European [ citation needed ] and North East Asian cultures frequently have traditions associating colors with four or five cardinal points.
