Angle and Distance method |
In this method, distances between the stations are laid off to scale and angles or bearings are plotted. Thus, the traverse stations are plotted with reference to the previous station. Therefore, the accuracy of the location of each station on the plan evidently depends upon the accuracy with which previous points are plotted. Even if there is a slight error in plotting, the error gets accumulated and the position of the last station may be displaced to a considerable distance from its true position. So, this method is used for plotting of small traverse or for traverse of low accuracy. |
