Application of Coordinate Measuring by Electronic Total Station Instrument to Traverse Survey

This paper introduces the method of traverse survey using direct measuring three-dimensional coordinates of control point by electronic total station instrument.This method can automatically measure three-dimensional coordinates and adjust errors,which breaks through the traditional model of traverse survey and can not need measure the side and angle,respectively.The method has advantages such as implementation simple,automatic calculation and check,high precision.It can be widely applied to hydropower engineering.
