Height of Observer Solution

STEP 0: Pre-Calculation Summary
Formula Used
Height of Observer = 0.0673*Distance between Two Points^2
h = 0.0673*D^2
This formula uses 2 Variables
Variables Used
Height of Observer - (Measured in Meter) - Height of observer is the length or vertical length of the observer.
Distance between Two Points - (Measured in Meter) - Distance between Two Points is defined as the length of space between two points. For finding the distance when curvature effects are considered, the value must be considered in kilometres.
STEP 1: Convert Input(s) to Base Unit
Distance between Two Points: 35.5 Meter --> 35.5 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
h = 0.0673*D^2 --> 0.0673*35.5^2
Evaluating ... ...

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)
Permissible Closing Error for Precise Levelling
Go Closing Error = 4*sqrt(Distance between Two Points)
Reduced Level given Height of Instrument
Go Reduced Level = Height of Instrument-Back Sight
Back Sight given Height of Instrument
Go Back Sight = Height of Instrument-Reduced Level
Height of Instrument
Go Height of Instrument = Reduced Level+Back Sight
Correction on Refraction Error
Go Refraction Correction = 0.0112*Distance between Two Points^2
Height of Observer
Go Height of Observer = 0.0673*Distance between Two Points^2
Combined Error Due to Curvature and Refraction
Go Combined Error = 0.0673*Distance between Two Points^2

Height of Observer Formula

Height of Observer = 0.0673*Distance between Two Points^2
h = 0.0673*D^2

What is Visible Horizon?

It is the line at which the sky and Earth appear to meet. it is also called a visual horizon or an apparent horizon.
