Altitude and azimuth are two key terms used in astronomy and navigation. Altitude is the angle measured vertically between an object and the observer's horizon, while azimuth is the angle measured horizontally from the observer's northern point. These terms are essential in determining the location and movement of celestial bodies and objects on the earth's surface. When referring to synonyms for altitude, terms like elevation, height, and distance above sea level often come to mind. For azimuth, words like compass bearing, direction, and orientation are commonly used. Both altitude and azimuth are important concepts utilized in various fields of study, including aviation, geography, astronomy, and marine navigation.
