or horizon coordinate system,
astronomical coordinate system in which the position of a body on the celestial sphere is described relative to an observer's celestial horizon and zenith.

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.
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.
