Earth curvature calculator with refraction
WebJan 16, 2024 · The formula for computing the combined effect of curvature and refraction is: C + R = 0.021K2 Where C = correction for curvature … WebWhat is curvature effect during surveying? In case of a long sight the horizontal line is not a level line due to curvature of the earth. The vertical distance between a horizontal line and the level line represents the effect of curvature of the earth.
