Basic Surveying
Question 1
1.1. List the THREEbasic methods of determining a distance.
BSV521S
(3)
1.2. There are TWO PRINCIPALCLASSIFICATIONSof surveying. Name BOTH and explain them
in detail.
(6)
1.3. Describe how to detect the presence of parallax when looking through the telescope of an
automatic level or a theodolite. Additionally, explain how to focus the crosshairs to
eliminate parallax.
(6)
1.4. Setting out involves using surveying equipment and techniques to transfer information
from a plan to the ground. Describe the THREEdistinct elements of setting out.
(3)
[18]
Question 2
2.1. Calculate oriented directions for the traverse by completing the direction sheet on Data
Sheet 1. Use the said data sheet for all your calculations. Please detach the data sheet and
submit it along with your examination booklet.
(12)
2.2. Please calculate the final coordinates for the traverse points using the information
provided in Data Sheet 2. Utilize the Bowditch Rule to adjust the traverse. Keep in mind
that the directions are oriented, and the distances are the final horizontal distances. Please
detach the data sheet and submit it along with your examination booklet.

Question 3
3.1. Use the following Formula and the observations at P, to answer the following questions.
~Hab = H1- Hsig+ Sab/Tan(Z)+ {1-k).S2/{2R)
Where R is earth radius (use R = 6 365 km), and k is an assumed relative ray curvature
factor (use k = 0.13).
