Horizontal direction measured clockwise from the meridian plane.
The length of arc measured clockwise along the astronomical horizon (in degrees of arc) from the adopted reference direction, usually true north, to that point on the horizon where the particular object or its projection is located; north is defined as 0° (or 360°), east is 90°, south is 180° and west is 270°.
The direction or bearing toward which a sloping surface faces (e.g., a north-facing slope has an azimuth angle of 360°; a northeast-facing slope, an azimuth angle of 45°).
an angle indicating an azimuth in which the positional information satellite is present with the North at the reference point as a reference (e
The angle measurement of horizontal dimension on an optically generated display. Normally zero azimuth is taken to be the center of the field of view and dimensions to the right and left are positive and negative azimuth angles. Back Surface Mirror A mirror who's reflective coating is on the opposite side of the optical material from the incident radiation. Back surface coating is used often in visible optics to help protect the mirror surface. Back surface coating is normally not used in infrared optics due to the additional attenuation caused by the passage of radiation through the optical element.
(Z). Angle within the nautical triangle between the observer's meridian and the vertical circle through the body. Gives the bearing of the body from the observer.
Azimuth is a term used to describe the orientation of a specimen in the imaging plane (stage) of a DIC microscope. On a graph having polar coordinates graduated in 360 degrees, the azimuth angle is subtended between a fixed reference (designated as zero degrees) and a vector rotated about the origin. The term is also frequently employed to describe the direction(s) of illumination of wavefronts emanating from a restricted aperture.
the angle between the horizontal direction (of the sun, for example) and a reference direction (usually North, although some solar scientists measure the solar azimuth angle from due South).
