Azimuth or azimuth comes from the Arabic "as-sumut", plural of "as-samt", means the address, the zenith.

The azimuth is the angle that forms the vertical circle that passes through a point of the celestial sphere or the globe with the meridian. It is one of the two coordinates of the altacimuthal system or horizontal astronomical coordinate system.

The other coordinate is the height, which is measured as the angular distance of a celestial body over the horizon, that is, the angle between the plane of the horizon and the line that joins the observer and the celestial body, or the arc of vertical circumference that extends between the celestial body and the horizon.

The word "azimuth" is also used to indicate a type of projection on the maps. If a paper is supported on a single point of an illuminated globe, the projection of the globe on the paper results in an azimuthal projection map. Azimuthal projection maps are used to represent polar regions, since the poles normally appear near the center, with the meridians that join in them and separate from each other as they move away from the poles. Polar regions appear relatively undistorted, but it grows as meridians get closer to equatorial areas.
