The paper introduces the principle and method of electronic trigonometric leveling by dot method using total station. It is to form a brand-new leveling model on the basis of mathematics model transformation of trigonometric leveling. It improves the precision of conventional trigonometric leveling and remedies the shortcomings that the leveling is restricted by certain conditions and the absolute precision of GPS elevation measurement is low. The method has offered a rapid way for elevation control measurement.
