Surveying instrument of high precision, can measure both vertical and horizontal angles, unlike a level telescope which is limited to the flat angles. The name is believed to come from the Greek- meaning, The Eye of God.
taking readings using theodolite keeping the vertical circle of the instrument on left side of the observer is called a face left observation and to measure horizontal angle the instrument is rotated(swing) in horizontal plane with respect to the vertical axis in a clockwise direction called rigt swing.
For surveying, there are some use of tools. Look at them, The Dividing Engine, Chains, Calculating device (non electric), leveling machine , strange and some other. These tools are very unique to use.

The process of measuring property to determine the boundaries of a person's land is called land surveying. It involves determining the size and shape of a piece of land and identifying its boundaries using specialized equipment and techniques. Land surveying is crucial for establishing property lines, resolving boundary disputes, and creating accurate maps.

The line of collimation in surveying is an imaginary line that extends from the objective lens of a surveying instrument to the crosshairs in the telescope. It helps ensure the instrument is properly aligned and level for accurate measurements. By keeping the line of collimation straight and horizontal, surveyors can minimize errors in their readings.
