Difference in Elevation between Two Points using Barometric Levelling
Go Distance between Points = 18336.6*(log10(Height of point A)-log10(Height of point B))*(1+(Temperature at Lower Ground Level+Temperature at Higher level)/500)
Difference in Elevation between Ground Points in short lines under Trigonometric levelling
Go Elevation Difference = Distance between Points*sin(Measured Angle)+Height of point A-Height of point B
Distance between Two points under Curvature and Refraction
Go Distance between Two Points = (2*Earth Radius in km*Error due to Curvature+(Error due to Curvature^2))^(1/2)
Distance for small errors under Curvature and Refraction
Go Distance between Two Points = sqrt(2*Earth Radius in km*Error due to Curvature)
Angle of Dip for Compass Surveying
Go Dip Angle = Distance between Two Points/Earth Radius in km*(180/pi)
Error Due to Curvature Effect
Go Error due to Curvature = Distance between Two Points^2/(2*Earth Radius in km)
Distance to Visible Horizon
Go Distance between Two Points = sqrt(Height of Observer/0.0673)
Permissible Closing Error for Rough Levelling
Go Closing Error = 100*sqrt(Distance between Two Points)
Permissible Closing Error for Ordinary Levelling
Go Closing Error = 24*sqrt(Distance between Two Points)
Permissible Closing Error for Accurate Levelling
Go Closing Error = 12*sqrt(Distance between Two Points)

What is Refraction effect in Surveying?

Refraction of the ray passing through the atmosphere from the signal to the observer is the main source of external error. The rays of light while passing through layers of air of different densities refract or bend down. These densities depend upon the temperature and pressure at all points along the track of the rays.

How to Calculate Correction on Refraction Error?

Correction on Refraction Error calculator uses Refraction Correction = 0.0112*Distance between Two Points^2 to calculate the Refraction Correction, The Correction on Refraction Error is defined as the improvement given against the refraction error. The average refraction correction can, however, be taken as 1/7th of the curvature correction. Refraction Correction is denoted by cr symbol.
