Stadia Interval Solution

STEP 0: Pre-Calculation Summary

Formula Used

Stadia Interval = Revolution of Screw*Pitch Screw
S_i = m*P_screw
This formula uses 3 Variables

Variables Used

Stadia Interval - (Measured in Meter) - Stadia interval is the distance on the rod between the apparent positions of the two stadia hairs.
Revolution of Screw - Revolution of screw is the number of revolutions made for the micrometer screw.
Pitch Screw - (Measured in Meter) - Pitch Screw is the distance between screw threads and is commonly used with inch sized products and specified as threads per inch.

STEP 1: Convert Input(s) to Base Unit

Revolution of Screw: 3.1 --> No Conversion Required
Pitch Screw: 5 Meter --> 5 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Vertical Distance between Center of Transit and Rod Intersected by Middle Horizontal Crosshair

Go Vertical Distance = 1/(2*((Stadia Factor*Rod Intercept*sin(2*Vertical Inclination of Line of Sight))+(Instrument Constant*sin(Vertical Inclination of Line of Sight))))

Horizontal Distance between Center of Transit and Rod

Go Horizontal Distance = (Stadia Factor*Rod Intercept*(cos(Vertical Inclination of Line of Sight))^2)+(Instrument Constant*cos(Vertical Inclination of Line of Sight))

Staff Intercept in Gradienter given Horizontal Distance

Go Staff Intercept = Distance between Two Points/((100*cos(Vertical Angle)^2*0.5*sin(2*Vertical Angle))/(Revolution of Screw*Distance in One Turn))

Horizontal Distance using Gradienter

Go Distance between Two Points = Staff Intercept*(100*cos(Vertical Angle)^2*0.5*sin(2*Vertical Angle))/(Revolution of Screw*Distance in One Turn)

Staff Intercept in Gradienter given Vertical Distance

Go Staff Intercept = Vertical Distance/((100*sin(2*Vertical Angle)*0.5*sin(Vertical Angle)^2)/(Revolution of Screw*Distance in One Turn))

Vertical Distance using Gradienter

Go Vertical Distance = Staff Intercept*(100*sin(2*Vertical Angle)*0.5*sin(Vertical Angle)^2)/(Revolution of Screw*Distance in One Turn)

Distance Equation given Index Error

Go Distance between Two Points = (Multiplying Constant*Staff Intercept/(Revolution of Screw-Index Error))+Additive Constant

Staff Intercept

Go Staff Intercept = Distance between Two Points*(tan(Vertical Angle to Upper Vane)-tan(Vertical Angle to Lower Vane))

Stadia Distance from Instrument Spindle to Rod

Go Stadia Distance = Intercept on Rod*((Focal Length of Telescope/Rod Intercept)+Stadia Constant)

Intercept on Rod between Two Sighting Wires

Go Intercept on Rod = Stadia Distance/((Focal Length of Telescope/Rod Intercept)+Stadia Constant)

Vertical Distance between Instrument Axis and Lower Vane

Go Vertical Distance = Distance between Two Points*tan(Vertical Angle to Lower Vane)

Additive Constant or Stadia Constant

Go Stadia Constant = (Focal Length of Telescope+Distance from Center)

Stadia Interval

Go Stadia Interval = Revolution of Screw*Pitch Screw

Stadia Interval Formula

Stadia Interval = Revolution of Screw*Pitch Screw
S_i = m*P_screw

What is Stadia in Surveying?

A surveying method for determination of distances and differences of elevation by means of a telescopic instrument having two horizontal lines through which the marks on a graduated rod are observed

How to Calculate Stadia Interval?

Stadia Interval calculator uses Stadia Interval = Revolution of Screw*Pitch Screw to calculate the Stadia Interval, The Stadia Interval formula is defined as the distance on the rod between the apparent positions of the two stadia hairs. As you look at a stadia rod through a transit telescope, the stadia hairs seem to intercept an interval on the rod. Stadia Interval is denoted by S_i symbol.

How to calculate Stadia Interval using this online calculator? To use this online calculator for Stadia Interval, enter Revolution of Screw (m) & Pitch Screw (P_screw) and hit the calculate button. Here is how the Stadia Interval calculation can be explained with given input values -> 15.5 = 3.1*5.

FAQ

What is Stadia Interval?

The Stadia Interval formula is defined as the distance on the rod between the apparent positions of the two stadia hairs. As you look at a stadia rod through a transit telescope, the stadia hairs seem to intercept an interval on the rod and is represented as S_i = m*P_screw or Stadia Interval = Revolution of Screw*Pitch Screw. Revolution of screw is the number of revolutions made for the micrometer screw & Pitch Screw is the distance between screw threads and is commonly used with inch sized products and specified as threads per inch.

How to calculate Stadia Interval?
