Surveying Questions and Answers – Plane Table – Two Point Problem

This set of Surveying Multiple Choice Questions & Answers (MCQs) focuses on “Plane Table – Two Point Problem”.

1. Location of points is already done while considering two point problem.
a) False
b) True
View Answer

Answer: b
Explanation: Two point problem is only considered when station point is able to visualize two other points of the traverse. By this, other points of the traverse can be formed and the points are joined to form a traverse.

2. Error occurred due to orientation can be checked by _____________
a) Calculating table area
b) Calculating area
c) Measuring bearings
d) Measuring angles
View Answer

Answer: d
Explanation: Orientation is the main process in case of plane tabling. Proper orientation must be done while carrying out this process. Error due to improper orientation can be checked by measuring angles and their differences.

3. Which among the processes having more accuracy in its output?
a) Total station
b) Plane table surveying
c) Chain surveying
d) Compass surveying
View Answer

Answer: a
Explanation: Plane table surveying is a rough process conducted in order to have an idea of the land and its condition for construction. Due to this, it is not capable of producing accurate output in its recording.

4. Which of the following step can affect the entire process?
a) Traversing
b) Alidade
c) Orientation
d) Chaining
View Answer

Answer: c
Explanation: All the steps involved in plane tabling are quite needed and must be done with more care. But the orientation step, which is the heart of this process, must be done with at most importance and with acre so that remaining steps won’t get disturbed.

5. For fixing any point, auxiliary point must be chosen.
a) True
b) False
View Answer

Answer: a
Explanation: Auxiliary point is a reference point that must be considered so that the points remaining in the traverse can be fixed. By this the entire traverse can be completed within no time.

6. Which of the following steps is involved in plane table surveying?
a) Tacheometric surveying
b) Measuring bearings
c) Measuring angles
d) Changing station points
View Answer

Answer: d
Explanation: Plane table surveying involves simple steps like orientation, changing table to station points, usage of alidade etc. But these can cause a serious error which can lead to repeating the entire process.

7. Which process involves more labor work?
a) Chaining
b) Compass surveying
c) Plane table surveying
d) Theodolite surveying
View Answer

Answer: c
Explanation: Plane table surveying involves more labor work due to the fact that the table present in this process needs to be shifted to the station points whenever it is necessary. It is to be done so as to cover the entire traverse.

8. How many alternatives were available in case of two point problem?
a) No alternatives
b) Maximum Two
c) Minimum one
d) Maximum one
View Answer

Answer: b
Explanation: Two point and three point problems involve an alternative solution because this involves more cases as every traverse doesn’t form the same polygon. Roughly two alternatives will be present in each.

9. Which process of plane table surveying is a tedious one?
a) Resection
b) Trisection
c) Intersection
d) Radiation
View Answer

Answer: a
Explanation: Resection, which involves both three point and two point problems, is considered as the tedious process when compared to the remaining classifications. These are done so as to decrease the errors due to improper orientation.

10. Two point problem involves in ______________
a) Locating details
b) Locating station points
c) Locating angles
d) Locating bearings
View Answer

Answer: b
Explanation: Two point problem is used only in case of determining the station points by considering different procedures which involve an auxiliary point.
