Try a few questions
- Practice question 1
A compass survey uses bearing readings taken at each station to determine direction, rather than relying solely on
- A.a factor entirely unrelated to direction or bearing
- B.chain measurement exclusively, with no reference to direction at all
- C.angular measurement with a theodolite
- D.any method of measurement whatsoever, since compass surveys use none
Show the answer
C. angular measurement with a theodolite
Compass surveys specifically substitute bearing readings for the angular measurement a theodolite would otherwise provide.
- Practice question 2
A well-conducted reconnaissance of the area to be surveyed is typically carried out
- A.at no particular stage, since reconnaissance serves no practical purpose
- B.before detailed survey work actually begins
- C.only after all detailed survey work has already been fully completed
- D.a factor entirely unrelated to the timing of the survey itself
Show the answer
B. before detailed survey work actually begins
Reconnaissance is specifically conducted before detailed survey work, helping to plan the approach to the area.
- Practice question 3
Offsets, in chain surveying, are short perpendicular measurements taken from the main survey line to
- A.no feature of any kind, since offsets measure nothing in particular
- B.a completely unrelated, distant survey line elsewhere
- C.a factor entirely unrelated to the survey line itself
- D.a nearby feature, such as a building corner
Show the answer
D. a nearby feature, such as a building corner
Offsets are specifically these short perpendicular measurements connecting the survey line to nearby features.
