What does an azimuth measure?

An azimuth is specifically defined as a horizontal angle that measures direction relative to a reference point, typically true north. It is expressed in degrees, with a full circle being 360 degrees. This measurement allows navigators to plot a course or find a direction on a map effectively. For instance, if a navigator is instructed to head southeast, they might receive an azimuth of 135 degrees, which assists in precise directional travel.

Distance measurement, contour elevation, and height above sea level pertain to different concepts in land navigation. While they are all vital components in understanding terrain and navigation, they do not relate to the concept of azimuth, which is solely concerned with direction indicated by degrees from a set reference point.
