azimutais

Azimutais is a term used in some languages to refer to azimuth-related values or directions. The word stems from azimuth, which originates from the Arabic al-samt, passing through Persian and French before entering other languages. In practice, azimutais can denote the set of azimuth measurements or the azimuthal directions themselves within a given context.

In navigation and astronomy, an azimuth is the angle measured in the horizontal plane from a reference direction, usually true north, clockwise to the projection of a line or object. Azimuth values are typically expressed in degrees, spanning from 0° to 360°. For example, an object due east has an azimuth of 90°, while due south is 180°. Azimutais, as a plural concept, would refer to multiple such azimuth values or to azimuthal directions in a given dataset or observation.

Azimuth is commonly paired with altitude (or elevation) in the horizon coordinate system, forming the alt-az framework used to locate objects in the sky or on the ground. Related tools and methods include compasses, theodolites, and GPS-based systems that provide azimuth information, often with adjustments for magnetic declination or local reference frames.

In cartography, azimuthal concepts appear in azimuthal projections, a class of map projections that project the sphere onto a plane from a chosen central point, preserving certain directions or distances from that point.
