This video explains the solution of an example/numerical related to case 2 of stadia method of tacheometric surveying, in which the staff is held vertical and line of sight is inclined.
This video explains the following aspects:
1. How data can be converted into sketch/figure
2. Determination of horizontal distance in an uneven terrain/mountainous area
3. Usage of formulas derived in Case 2 of Stadia method
4. Determination of reduced level/height of an elevated object.
