The Correct Option is C
Solution and Explanation
In the field of Geo Engineering and Geo Informatics, particularly within surveying, understanding the temporary adjustments of a surveyor's compass is crucial. These adjustments ensure the compass is ready for accurate measurements. The two primary temporary adjustments required are:
- Centering: This step involves positioning the compass precisely over the point of interest or survey station. Accurate centering ensures that the measurements taken are relevant to the exact location intended for the survey.
- Levelling: This adjustment ensures that the compass is placed in a horizontal position. A level compass is essential for obtaining accurate angle measurements since any tilt can lead to errors in data collection.
Therefore, the correct response to the question concerning the temporary adjustments of a surveyor's compass is "centering and levelling."
