The azimuth is the angle formed between a reference direction (in this example north) and a line from the observer to a point of interest projected on the same plane as the reference direction orthogonal to the zenith.
The azimuth angle is the compass direction from which the sunlight is coming. At solar noon, the sun is always directly south in the northern hemisphere and directly north in the southern hemisphere. The azimuth angle varies throughout the day as shown in the animation below.
The azimuth is the angle between the spot where that line crosses the horizon and the reference direction. If true north is used as reference, it is represented by an azimuth of 0°, and angle values increase towards the east. This means, for example, that an azimuth of 180° means due south.
Azimuth refers to the angular distance from the north or south point of the horizon to the vertical circle’s foot through a heavenly body. This angular distance and its calculation certainly have important applications in physics.
The azimuth angle (or longitude) of a given position on Earth, commonly denoted by λ, is measured in degrees east or west from some conventional reference meridian (most commonly the IERS Reference Meridian); thus its domain (or range) is −180° ≤ λ ≤ 180° and a given reading is typically designated "East" or "West".
This azimuth calculator is used to find the horizontal angle between a reference direction and a line from an observer to a point of interest. θ = atan2(sin(Δλ) * cos(φ2), cos(φ1) * sin(φ2) – sin(φ1) * cos(φ2) * cos(Δλ))
The azimuth of a heading is the horizontal angle measured clockwise from a meridian line, which points towards true north. Azimuth is represented by the symbol α, and usually measured in...
The azimuthal angle is an angle measured from the x-axis in the xy-plane in spherical coordinates, denoted theta in this work.
Illustrated definition of Azimuth: A horizontal angle measured clockwise from North.
azimuth, the angular distance from the north or south point of the horizon to the foot of the vertical circle through a heavenly body. The azimuth of a horizontal direction is its deviation from the north or south.
