azimuth
[cartography] The horizontal angle, measured in degrees, between a baseline drawn from a center point and another line drawn from the same point.
Azimuthal Projection
A map projection on which the azimuths of all points are shown correctly with respect to the center (Snyder 1987, p. 4). A plane tangent to one of the Earth's poles is the basis for polar azimuthal projection.
Azimuth is often - some consider incorrectly - referred to as a bearing. Nowadays in astronomy, azimuth sometimes is measured from the north.
Azimuth is usually measured in degrees (°). The concept is used in many practical applications including navigation, astronomy, mapping, mining and artillery.
What is an azimuthal map projection?
Imagine a plane being placed . If a light source inside the globe projects the graticule onto the plane the result would be a planar, or azimuthal, map projection.
Azimuthal Projections
Introduction
Given a reference point A and two other points B and C on a surface, the azimuth from B to C is the angle formed by the minimum-distance lines AB and AC (which, on a sphere, ...
Azimuth: The horizontal direction from one point on the earth to another, measured clockwise in degrees around the observer's horizon from north. So an object due north has an azimuth of 0°, one due east 90°, south 180° and west 270°.
AZIMUTH COMPUTATIONS
6-16. The azimuth of a line is the horizontal angle (measured clockwise) from a base direction to the line in question. To compute a traverse, surveyors determine the azimuth for each traverse leg.

azimuth
An azimuth is the angle that a line makes with a meridian (a line of longitude), going clockwise from north.

Azimuth
The direction of travel or the direction between two points in reference to true or magnetic north. When expressed in degrees, its value ranges from 0 to 360°. A compass heading is an azimuth.

An azimuth bearing uses all 360° of a compass to indicate direction. The compass is numbered clockwise with north as 0°, east 90°, south 180°, and west 270°. So a bearing of 42° would be northeast and a bearing of 200° would be southwest, and so on.
An azimuthal or planar projection is usually tangent to a specific point on earth's surface, but may also be secant. This point, or focus, may be a pole, the equator, or other oblique point.
The azimuth is an angle, in degrees, measured to the east of north. The distance is in map units (meters for a metered database, like UTM).
The AZIMUTHAL family of projections, also called ZENITHAL or PLANAR, is produced by transforming the Earth's surface onto a plane. Members of the family are distinguished from each other by the different perspective points used to construct them.

The angle, or argument, of a complex number (x, y), is a mathematical version of its geographical azimuth: it is the angle formed between the ray from (0,0) to (x, y) and the ray from (0,0) to (1,0) ("due east"). It is sometimes written arg(x, y).

The technique uses a bit trigonometry by calculating the "direction cosines" of the fitted plane to identify its orientation as an azimuth value between 0 (north) and 360. For the example location, the azimuth is 221 degrees (SW bearing).
Datum - A mathematical reference framework for geodetic coordinates defined by the latitude and longitude of an initial point, the azimuth of a line from this point, and the parameters of the ellipsoid upon which the initial point is located.
Geodesy Calculator also calculates bearing, azimuth, distance, and the end coordinate. The Range Ring tool allows users to create geodetically correct concentric ellipses at user-specified intervals anywhere on the globe.

Coordinate Geometry (COGO) A computerized surveying - plotting calculation methodology created at MIT in the 1950's. Positions are measured relative to a given base position by distance and azimuth, rather than an absolute coordinate.
Generally, the paper is either flat and placed tangent to the globe (a planar or azimuthal projection) or formed into a cone or cylinder and placed over the globe (cylindrical and conical projections).
