| Abstract: | In this paper,a more strict formula for calculating the correction of atmospheric refraction is derived by the intergral method and a reduced formula applicable to leveling is given.By the field test,the conclusion is drawn that with the reduced formula to calculate the refraction correction for each leveling point only several samples of meteorologic factors and their average need to be taken in a section.The way,only a little work is added, but the better results can be obtained. |
