CE 301 Exam 1 questions with complete
solutions graded A+
Four methods of measuring distances - correct answer ✔✔Estimating, pacing, measuring wheel, taping,
counting
Most accurate method of distance measuring - correct answer ✔✔Taping
Least accurate method of distance measuring - correct answer ✔✔Estimating
What is a disadvantage of using the wheel odometer outside? - correct answer ✔✔Uneven ground OR
might not proceed in a straight line
Will the measured wheel distance be longer or shorter than the actual horizontal distance? - correct
answer ✔✔Longer
How are the tapes used in CE 301 lab different from cut and add tapes? - correct answer ✔✔Fully
graduated
Explain the difference between turning points and benchmarks. - correct answer ✔✔Turning points are
temporary and their elevation is determined by the surveyor. Benchmarks are permanent and their
elevation has been determined by a previous survey.
Give two reasons why we measure angles and distances twice. - correct answer ✔✔Increase accuracy
Check the first measurement
Identify three measurement methods to prolong (and measure) a line around obstacles such as rivers
and trees. - correct answer ✔✔Triangulation around the obstacle (equilateral triangle)
Right angle offset OR 90 degree offset
Random line method through the obstacle using resultant and offset angles
