In surveying which both horizontal and vertical positions of a point ...
Tacheometry is a system of rapid surveying by which the positions, both horizontal and vertical, of points on the earth’s surface relative to one another are determined without using a chain or tape or a separate leveling instrument.
Tacheometry is also called as telemetry,tachematry.
Hence the correct answer is option D.

In surveying which both horizontal and vertical positions of a point ...
Definition of Tacheometry:
Tacheometry is a surveying technique used to determine both horizontal and vertical positions of a point using an optical instrument. It is commonly used in engineering and construction projects to gather accurate measurements and data for various purposes.
Explanation of the options:
a) Tachemetry: This option is incorrect as it is not a recognized term in surveying. It may be a misspelling or a term used in a different context.
b) Tacheometry: This option is correct. Tacheometry is a surveying technique that involves the use of an optical instrument, such as a tacheometer or theodolite, to measure both the horizontal and vertical positions of a point. It is a fast and efficient method that provides accurate measurements for various surveying applications.
c) Telemetry: This option is incorrect. Telemetry is a different concept that involves the automatic measurement and transmission of data from remote or inaccessible locations to a receiving station. It is commonly used in fields such as telecommunications, medicine, and environmental monitoring, but it is not directly related to surveying.
Conclusion:
The correct option is d) All the above as tacheometry is the technique in surveying that involves determining both horizontal and vertical positions of a point using an optical instrument. The other options mentioned, such as tachemetry (misspelled) and telemetry (unrelated), are incorrect. Tacheometry is a valuable surveying technique that helps engineers and surveyors gather accurate measurements and data for their projects.
