Azimuth is measured from the north point (sometimes from the south point) of the horizon around to the east; altitude is the angle above the horizon. The horizontal coordinate system is a celestial coordinate system that uses the observer's local horizon as the fundamental plane.It is expressed in terms of altitude (or elevation) angle and azimuth.he horizontal coordinate system is a celestial coordinate system that uses the observer's local horizon as the fundamental plane.
