What is the definition of a back azimuth?

The definition of a back azimuth is the opposite direction of an azimuth. In navigation and orienteering, an azimuth is a compass direction measured in degrees from a baseline, typically North, clockwise around a circle. To find the back azimuth, one would add or subtract 180 degrees from the original azimuth, effectively flipping the direction. This concept is essential for navigation, as it allows individuals to determine the inverse path and retrace their steps accurately.

Understanding the back azimuth is crucial for scenarios where ranging or positional adjustments are required, as it aids in orientation and understanding the relative positioning of various points on a map or in the terrain. The other definitions presented do not relate to this specific concept of direction reversal in navigation.
