What is magnetic bearing of line in theodolite survey?
The magnetic bearing of a line in theodolite surveying is the horizontal angle measured clockwise from the magnetic north direction to the line. This bearing is used to orient the theodolite and accurately measure angles during surveying work. It is important to account for magnetic declination when converting magnetic bearings to true bearings.
Why is it necessary to take both the vernier readings of theodolite?
Taking both the upper and lower vernier readings of the theodolite helps to eliminate any errors caused by misalignment or wear in the instrument, resulting in a more accurate measurement. Comparing the two readings can also help detect any potential issues with the theodolite's precision.
What is the difference between the principle of Tacheometric survey and Totalstation survey?
The main difference is the method of measuring distances. Tacheometry is optical. A total station uses electromagnetic waves. Distances measured using Tacheometry are determined by multiplying the difference in readings to a levelling staff between the upper and lower stadia hairs, by a constant (usually 100). A Total station, by definition, is a theodolite with a built-in EDM measuring device. This sends out a signal of a known wavelength to a reflector and calculates the distance by measuring the time it takes for the signal to return.
How do you spell the word survey?
The word is spelled "survey."
What is parcellary survey?
a survey
What is principle of theodolite?
principle of theodolite is based on the principle of trigonometry.
Why need centering in theodolite surveying?
Centering in theodolite surveying is necessary to ensure accurate measurements by aligning the theodolite's telescope with the survey point. This process helps eliminate errors caused by misalignment, which can lead to inaccurate readings and data. Proper centering ensures that survey points are measured precisely and the survey results are reliable.
What is the difference between theodolite and tachometer?
A theodolite is a survey instrument. A tachometer tells you how many Revs per minute an engine is turning.
What is the purpose of a theodolite?
It reduce the time in survey and give accurate dimension
Definition of face left and face right observation?
Face left observation(In theodolite survey):If the face of the vertical circle is to the left of the observer, the observation of the angle is known as Face left observationFace Right observation(In theodolite survey):If the face of the vertical circle is to te right of the observer, the observation of the angle is known as Face right observation
What do you mean by face left and face right observations?
