| Abstract: | The standard method of measuring elevation is difficult to be carried out in the complex topographic area.In the paper,a method of total station trigonometric leveling was used to eliminate or reduce atmospheric refraction,instrumental errors and other effect on measurement accuracy,so as to meet the measurement accuracy standard of second-order leveling.Finally the result was verified through the practical application. |
