azimuth

az·i·muth

A0560700 (ăz′ə-məth)n.1. The horizontal angular distance from a reference direction, usually the northern point of the horizon, to the point where a vertical circle through a celestial body intersects the horizon, usually measured clockwise. Sometimes the southern point is used as the reference direction, and the measurement is made clockwise through 360°.2. The horizontal angle of an observer's bearing, measured clockwise from a reference direction such as true north.3. The horizontal angle of a projectile's motion, measured relative to a reference direction such as true north.

[Middle English azimut, from Old French, from Arabic as-sumūt, pl. of as-samt, the way, compass bearing : al-, the + samt, way (from Latin sēmita, path; see mei- in Indo-European roots).]

n. 1. the arc of the horizon measured clockwise from the south point, in astronomy, or from the north point, in navigation, to the point where a vertical circle through a given heavenly body intersects the horizon. 2. (in surveying) the angle of horizontal deviation, measured clockwise, of a bearing from a standard direction, as from north or south.

az·i·muth

(ăz′ə-məth) The horizontal angle measured clockwise between a celestial object and the northern point of the horizon as seen by the observer. Azimuth and altitude are the coordinates used to navigate with respect to the stars.

azimuth

Quantities may be expressed in positive quantities increasing in a clockwise direction, or in X, Y coordinates where south and west are negative. They may be referenced to true north or magnetic north depending on the particular weapon system used.

Azimuth

(religion, spiritualism, and occult)

One can locate a specific celestial object in several ways, most of which involve specifying two coordinates. The azimuth is one of the coordinates of such a system. Although the notion of azimuth is basically simple, it is not simple to explain. Imagine that a group of people are looking at a star. From where they are standing, they can measure the angle between the horizon and the star. This gives them one coordinate in terms of angular distance (called the altitude, for obvious reasons). Then imagine a geometric plane that, like some kind of gigantic wall, cuts through Earth, intersecting the north and south poles, the place where they are standing, and the point directly over their heads (the zenith). They then measure another angle with their surveying instrument, this time between the imaginary wall and the star. This angular distance gives them the azimuth.

azimuth

[′az·ə·məth] (astronomy) Horizontal direction of a celestial point from a terrestrial point, expressed as the angular distance from a reference direction, usually measured from 0° at the reference direction clockwise through 360°. (engineering) In directional drilling, the direction of the face of the deviation tool with respect to magnetic north. (geodesy) Horizontal direction on the earth's surface.

azimuth

i. A direction expressed as a horizontal angle, usually in degrees, measured clock-wise from a reference datum or direction, usually north. The azimuth will be a true zenith, grid azimuth, magnetic azimuth, or relative azimuth, depending upon which reference datum is used.
ii. The arc of the observer's rational horizon or the angle at his zenith contained between the observer's celestial meridian and the vertical circle through that body. It is the distance, measured in degrees, along the horizon westward from the south point of the horizon to the place where the vertical circle through an object intersects the horizon.
iii. As it pertains to aerial photography, the azimuth of a photograph is the clock-wise horizontal angle measured about the ground nadir point from the ground survey north meridian to the principal plane of the photograph. Also called azimuth of the principal plane.

azimuth

Astronomy navigation the angular distance usually measured clockwise from the north point of the horizon to the intersection with the horizon of the vertical circle passing through a celestial body

azimuth

The trajectory of an angle measured in degrees going clockwise from a base point. A disk azimuth alignment test checks for the correct positioning of the read/write head to the track.
