This set of Surveying Multiple Choice Questions & Answers (MCQs) focuses on “Terrestrial Photogrammetry”.
1. Stereoscopic measurement involves in __________
a) Fusing photographs
b) Stripping photographs
c) Tilting photographs
d) Placing vertical
View Answer
Explanation: The main purpose of using stereoscopic measurement is to fuse the photographs in to a single spatial image which can parallactically displace each of the photographs.
2. The errors caused due to terrestrial photogrammetry can be reduced by _______
a) Stereo photogrammetry
b) Terrestrial stereo photogrammetry
c) Remote sensing
d) GIS
View Answer
Explanation: The errors caused due to the plane table photogrammetry can be reduced or eradicated by using another photogrammetry method which is terrestrial stereo photogrammetry. This involves modern techniques which can be used for further purposes.
3. Which process is capable of covering maximum area with minimum effort?
a) Terrestrial photogrammetry
b) Remote sensing
c) GIS
d) Traversing
View Answer
Explanation: The coverage of maximum area involves more amount of information which can be done by terrestrial photogrammetry. This involves more information with less photographs taken.
4. Which among the following methods is easy in computing photographs?
a) Remote sensing
b) Plane table photogrammetry
c) Terrestrial photogrammetry
d) GIS
View Answer
Explanation: Terrestrial photogrammetry involves modern techniques which are used and easily understood by everyone. In the case of plane table photogrammetry, the main problem occurs at pairing of photographs.
5. Which among the following is the best mapping procedure?
a) Elite photogrammetry
b) plane table photogrammetry
c) Terrestrial photogrammetry
d) Aerial photogrammetry
View Answer
Explanation: Among the different mapping procedure involved, aerial photogrammetry is the best method till date. It is so because of the fact that more amount of information can be covered with less effort. But it is of high cost and due to this government will handle these types of works.
6. Which of the following is used in Terrestrial photogrammetry?
a) Horizon
b) Maps
c) Zenith
d) Azimuth
View Answer
Explanation: The use of existing maps is done in case of terrestrial photogrammetry as it serves as a reference for its improvement in further approach. It is used in both the classifications for improving accuracy.
7. In terrestrial method, both plotting recording are done simultaneously.
a) False
b) True
View Answer
Explanation: Though both terrestrial and plane table surveying indicate the same principle but in plane table both plotting and recording is done in the field, while terrestrial photogrammetry involves the same work but done at various places. This is the major difference between the two processes.
8. Which of the following processes cover entire area in a short span?
a) Aerial photogrammetry
b) Terrestrial photogrammetry
c) Theodolite surveying
d) Traverse surveying
View Answer
Explanation: Terrestrial photogrammetry involves in the usage of photo theodolite which is capable of comprising a vast are in a short span of time. It is also capable of producing accurate value which is suitable for producing required output.
9. Which of the following indicates the correct set of terrestrial photogrammetric classification?
a) Plane-table, stereo
b) Theodolite, terrestrial
c) Plane-table, terrestrial stereo
d) Theodolite, terrestrial stereo
View Answer
Explanation: Terrestrial photogrammetry involves two branches which are given as plane-table photogrammetry and terrestrial stereo photogrammetry. These are capable of studying ground from existing maps, and reconnaissance is made through this classifications.
10. Which among the following is capable of giving accuracy in its output?
a) Traverse surveying
b) Theodolite surveying
c) Aerial photogrammetry
d) Terrestrial photogrammetry
View Answer
Explanation: A terrestrial photogrammetry involves in the usage of photo theodolite which is having precision in its obtained result. The classification is done so as to improve the accuracy in the output based on the type of field employed.
