(Askeri) BOYLAM AÇISI: Arzın merkezinden, bir meridyen düzlemi ile, genel olarak, doğuya veya batıya doğru 180 derece ölçülen ve Greenwich'den geçen başlangıç meridyeni gibi, belirli bir meridyen düzlemi arasında teşekkül eden açı
Longitude is a coordinate that is used to specify positions on a sphere The longitude of a place is the distance of the place to the prime meridian, measured in degrees along a circle at a fixed distance to the poles of the sphere All places with the same longitude lie on a half-circle between the poles On Earth, the prime meridian of the common geographical coordinate system is the one passing through Greenwich in England In the sky, longitude is one of the coordinates used in the ecliptical and galactic coordinate systems The corresponding coordinate in the equatorial coordinate system is called right ascension The second coordinate needed to specify a position on a sphere is the latitude
The angular measurement of a point on the earth's surface, east or west of the prime meridian The prime meridian runs through Greenwich, England and is 0 degrees longitude Since measurements are made East and West, the maximum longitude value is 180 degrees Mathematically, longitudes are usually denoted as positive for easterly longitudes (e g , +71 degrees = 71 E), and negative for westerly longitudes (e g , -65 degrees = 65 W)
In general, an angular distance along a primary great circle from an adopted reference point On the Earth's surface, the angle between the Greenwich meridian (0o) and the meridian of a point on the Earth, measured eastward or westward from the former through 180o and labelled E or W to indicate the direction of measurement
(Meridians of) Angular distance east or west on the earth's surface, measured from the prime meridian that is 0° and runs through Greenwich, England The International Date Line is 180°
an imaginary great circle on the surface of the earth passing through the north and south poles at right angles to the equator; "all points on the same meridian have the same longitude"
distance on the Earth (measured in degrees) east or west from a reference line, usually the line running between the poles passing through Greenwich, England
distance east or west on the earth's surface, measured as an arc of the equator (in degrees up to 180o or by the difference in time) between the meridian passing through a particular place and a standard or prime meridian
Angular distance measured in degrees, minutes, and seconds 180 degrees east and west from the Prime Meridian, the imaginary north-south line through Greenwich, England
Angular distance in a great circle of reference reckoned from an accepted origin to the projection of any point on that circle Longitude on the Earth's surface is measured on the Equator east and west of the meridian of Greenwich and may be expressed either in degrees or in hours, the hour being taken as the equivalent of 15° of longitude Celestial longitude is measured in the ecliptic eastward from the vernal equinox The mean longitude of a celestial body moving in an orbit is the longitude that would be attained by a point moving uniformly in the circle of reference at the same average angular velocity as that of the body, with the initial position of the point so taken that its longitude would be the same as that of the body at a certain specified position in its orbit With a common initial point, the mean longitude of a body will be the same in whatever circle it may be reckoned
the East-West angular distance of a locality from the Prime Meridian The Prime Meridian is the location of the Greenwich Observatory in England and all points North and South of it
The longitude of a place is its distance to the west or east of a line passing through Greenwich. Compare latitude. He noted the latitude and longitude, then made a mark on the admiralty chart. Longitude is also an adjective. A similar feature is found at 13 degrees North between 230 degrees and 250 degrees longitude. the distance east or west of a particular meridian (=imaginary line along the Earth's surface from the North Pole to the South Pole) , measured in degrees latitude (longitudo , from longus )
Length; measure or distance along the longest line; distinguished from breadth or thickness; as, the longitude of a room; rare now, except in a humorous sense
The distance in degrees, reckoned from the vernal equinox, on the ecliptic, to a circle at right angles to the ecliptic passing through the heavenly body whose longitude is designated; as, the longitude of Capella is 79°
Imaginary lines that run from the North Pole to the South Pole The lines of longitude start at the Prime Meridian, in Greenwich, England Longitude measures how far west or east an object is from the Prime Meridian
Longitude is a west-east measurement of position on the Earth It is defined by the angle measured from a vertical plane lrunning through the polar axis and the prime meridian A line connecting all places of the same longitude is termed a meridian Longitude is measured in degrees, minutes, and seconds Measurements of longitude range from prime meridian (0 degrees) to 180 degrees West and East from this point
The angle of a location on the earth's surface usually expressed in degrees east or west of the Greenwich Meridian New York, for example, is at approximately 74° west
The arc or portion of the equator intersected between the meridian of a given place and the meridian of some other place from which longitude is reckoned, as from Greenwich, England, or sometimes from the capital of a country, as from Washington or Paris
The location east or west in reference to the Prime Meridian, which is designated at 0 degrees longitude The distance between lines of longitude are greater at the equator and smaller at the higher latitudes Time zones are correlated to longitude
