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?
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 case of small distances and production of large output is quite simple and easy.
2. Which of the following methods is widely used method of plane tabling?
Explanation: Among the following, traversing is adopted in a 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?
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?
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?
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 a wider scope in case of locating details regarding the points.
6. Which of the following is used to locate only details?
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 traversing method?
a) Locating points
b) Survey line placement
c) Measuring angles
d) Measuring bearings
Explanation: Traversing is a very commonly used method which is involved only in the survey line placement between the instrument stations in an open or closed traverse.
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?
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
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.
