This set of Surveying Multiple Choice Questions & Answers (MCQs) focuses on “Methods of Plane Tabling”.
1. Which of the following methods can be useful in having an enlarged output?
a) Intersection
b) Resection
c) Traversing
d) Radiation
View Answer
Explanation: An enlarged output is required in case of improving accuracy in the traverse area. It can be obtained only in case of radiation, as it is used in the case of small distances and the production of large output is quite simple and easy.
2. Which of the following methods is a widely used method of plane tabling?
a) Radiation
b) Intersection
c) Traversing
d) Resection
View Answer
Explanation: Among the following, traversing is adopted in the usual manner. It involves a very simple procedure and also gives more accurate values when compared to other processes.
3. Which of the following can give the best output?
a) Traversing
b) Intersection
c) Resection
d) Radiation
View Answer
Explanation: Though resection involves in more accuracy, it is more time consuming. By considering the time factor usually traversing is adopted and is given at most priority. It is also capable of giving accurate results.
4. Which of the following methods is more suitable in case of small distances?
a) Traversing
b) Radiation
c) Resection
d) Intersection
View Answer
Explanation: Radiation process involves in recreating the station to station distance in an enlarged manner. It requires a lot of time which makes it suitable only in case of small distances.
5. Which of the following methods is having a wider scope with the use of tacheometer?
a) Resection
b) Trisection
c) Intersection
d) Radiation
View Answer
Explanation: Alidade can be used to locate the points and determining the traverse. If the point to point distance can be obtained by tacheometer, radiation method can have wider scope in case of locating details regarding the points.
6. Which of the following is used to locate only details?
a) Radiation
b) Trisection
c) Resection
d) Traversing
View Answer
Explanation: Radiation and intersection are having a common point that they both are able to locate the details other than station points. With the information provided by these, instrument station points can be located.
7. Which of the following describes the usage of the traversing method?
a) Locating points
b) Survey line placement
c) Measuring angles
d) Measuring bearings
View Answer
Explanation: Traversing is a very commonly used method that is involved only in the survey line placement between the instrument stations in an open or closed traverse.
8. The figure indicates which of the following methods?
a) Traversing
b) Intersection
c) Radiation
d) Trisection
View Answer
Explanation: The above mentioned figure indicates the process of radiation in which the station point is extended till it meets the point on the sheet provided while conducting the process.
9. Which is of the following is used for locating details of the station points?
a) Radiation
b) Intersection
c) Trisection
d) Traversing
View Answer
Explanation: The location of plane table stations can be carried out by traversing and resection methods, which involve in determining only the station points. This key step because instrument has to be set at a definite point to continue further.
10. Which among the following set share the same working principle?
a) Traversing and Radiation
b) Traversing and trisection
c) Traversing and Resection
d) Traversing and intersection
View Answer
Explanation: Traversing and Radiation share the same working principle. The only difference is that in the case of radiation the observations are taken to those points which are to be detailed, while in case of traversing the observations are made to those points which will subsequently be used as instrument stations.
