direction calculations
Scope
After traverse angles have been adjusted to represent a closed geometric figure, and a starting direction has been determined or assumed, the direction of each line can be calculated. This is accomplished using either azimuths or bearings. Some field engi-neers prefer to calculate azimuths and others prefer to calculate bearings. It is purely a matter of personal preference because they both represent the same thing—a direction. However, azimuths are much easier to calculate. Since they are easier, fewer mistakes in calculations generally occur. Therefore, although the properties of both bearings and azimuths will be discussed, only the calculation of azimuths will be presented in this Section. It will also be shown how bearings can easily be obtained by converting from azimuths.
