principle of theodolite is based on the principle of trigonometry.
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.

If he disagrees with your survey, he will have to contract his own survey.
Survey
principle of theodolite is based on the principle of trigonometry.
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.
A theodolite is a survey instrument. A tachometer tells you how many Revs per minute an engine is turning.
It reduce the time in survey and give accurate dimension

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

A protractor is used for drawing and measuring angles.
Three important principles of sampling survey are: 1. Principle of validity 2. Princilpe of statistical regularity 3. Principle of optimization
