✍️ Sample FUNDAMENTAL SURVEYING Questions & Answers
1. What is the most probable value (MPV) in surveying?
The MPV is the arithmetic mean, which minimizes the sum of the squares of the residuals under the method of least squares.
2. In differential leveling, what is a 'backsight' (BS)?
A backsight is a rod reading taken on a point of known elevation (like a BM or turning point) to establish the instrument's height of instrument (HI).
3. What is 'trigonometric leveling'?
Trigonometric leveling calculates elevation differences using V = S times sin(vertical angle), where S is the slope distance.
4. Which traverse adjustment method distributes closure errors in proportion to the length of each side?
The Bowditch (Compass) Rule distributes latitude and departure errors proportionally to the length of each traverse course.
5. What is a 'turning point' (TP) in differential leveling?
A turning point is a temporary, solid point where both a foresight and backsight are taken, used to advance the level run when the instrument must be moved.
6. An 'equal-area' map projection preserves which property?
An equal-area (equivalent) projection maintains correct area relationships between mapped regions, though shapes are distorted.
