Azimutális

Azimutális is an adjective used in Hungarian to describe things relating to azimuth, the angle measured on a reference plane between a reference direction and the projection of a line to a point. The term originates from azimuth, a concept widely used in navigation, astronomy, and cartography to denote direction and bearing.

In navigation and astronomy, azimuth is a horizontal angular coordinate. When combined with altitude or elevation, as in the alt-azimuth system, it locates objects in the sky or on the ground: azimuth gives the direction along the horizon, while altitude or elevation gives height above the horizon. Different conventions exist for the zero point and the direction of increasing azimuth (for example measured clockwise from true north), which can vary by field or standard.

In cartography, azimuthal projections map points from a sphere to a plane tangent at a chosen point. This family includes the Lambert azimuthal equal-area projection, stereographic projection, orthographic projection, and gnomonic projection. Such maps are often used for polar regions or specific aviation and communication applications because they can preserve certain properties—distances, areas, or angles—from the projection point.

Etymology and usage: In Hungarian, azimutális describes attributes, coordinate formulations, or projection types that pertain to azimuth. The concept appears in geographic information systems, astronomy, and mapmaking to express directional relations, positioning, and the geometry of projections.
