| Abstract: | The calculation formula and its estimated formula for precision were deduced while introducing the principle of using the middle way electromagnetic wave surveying triangle elevation in the paper.The necessary condition,the important condition and the second condition of using the middle way replaced the exact leveling were analyzed.And the reliability of using the middle way to replace the exact leveling was validated by analyzing the measured data,and the survey plan with the middle way was made in the end. |
