Direction of lines in surveying
Direction calculations can be performed in either a clockwise or counter-clockwise manner about a traverse. There are specific rules for calculating in either direction. To calculate azimuths clockwise around a traverse: Subtract the interior angle from the back azimuth of the preceding line. To calculate azimuths counter … See more Azimuths are measured clockwise from North and vary from 0° to 360°. They require only a numerical value (35°, 145°, 215°, etc.). Azimuths may be referenced to true … See more By observation of the value of the azimuth, the surveyor should be able to instantly visualize where the azimuth is located. Whether it is in the Northeast quadrant, Southeast, Southwest, or Northwest. See more The following is the step-by-step procedure for calculating azimuth of line BC for the figure shown in Steps 1 through 4. See more To calculate azimuths about a traverse, it is necessary to obtain the back azimuth of a line. To calculate a back azimuth, simply add 180° to the azimuth of the line. Back Azimuth = Forward Azimuth + 180° For example, if a line has … See more Weba direction of a line expressed as the clockwise angle between the line and a given reference direction or meridian. azimuth axis. the vertical axis of a transit, passing through the alidade spindle and the leveling head; also called the standing axis. back azimuth. forward azimuth plus/minus 180 degrees.
