What are the function of a theodolite?

Measuring angles in the horizontal and vertical plane
Theodolite/Purpose

What is theodolite and explain its parts?

Theodolite consists of some main parts, such as: Telescope. Horizontal plate (Circle) Vertical Circle. Index frame.

What are the instrument used in theodolite surveying?

In its modern form it consists of a telescope mounted to swivel both horizontally and vertically. Leveling is accomplished with the aid of a spirit level; crosshairs in the telescope permit accurate alignment with the object sighted.

What does a theodolite consist of?

A modern theodolite consists of a movable telescope mounted within two perpendicular axes—the horizontal or trunnion axis, and the vertical axis. When the telescope is pointed at a target object, the angle of each of these axes can be measured with great precision, typically to seconds of arc.

Why is the theodolite important?

The theodolite is most accurate instrument used mainly for measuring horizontal and vertical angles. It can also be used for locating points on a line, prolonging survey lines, finding difference in elevations, setting out grades, ranging curves etc. ADVERTISEMENTS: (2) Non transit.

What are the equipment used in surveying?

The main pieces of surveying equipment in use around the world are the following: theodolite, measuring tape, total station, 3D scanners, GPS/GNSS, level and rod. Most survey instruments screw onto a tripod when in use.

What is theodolite survey and what its purpose?

A theodolite is a surveying instrument used for precise angular measurement in both horizontal and vertical planes.

Why do we use theodolite in civil engineering?

Theodolite uses for many purposes, but mainly it is used for measuring angles, scaling points of constructional works. For example, to determine highway points, huge buildings’ escalating edges theodolites are used. Measuring horizontal and vertical angles. Locating points on a line.

What are the basics of surveying?

It usually involves measurement, calculations, the production of plans, and the determination of specific locations. The surveyor may be called on to determine heights and distances; to set out buildings, bridges and roadways; to determine areas and volumes and to draw plans at a predetermined scale.

What is the purpose of instrument used in surveying?

surveyor’s level, instrument used in surveying to measure the height of distant points in relation to a bench mark (a point for which the height above sea level is accurately known). It consists of a telescope fitted with a spirit level and, generally, mounted on a tripod.

What is the function of a theodolite?

Theodolite Parts and Functions [A Detailed Guide]. 1. Leveling Head: Leveling head is used for three purposes; (i) It provides a bearing for the outer hollow spindle. 2. Limb or Lower Plate: The outer axis is attached to the lower plate which consists of a horizontal circle, usually whole circle division, i.e., with whole circle graduation: from 3. 4. 6. 7. 8. 9. 10. 11.

What is the purpose of a theodolite?

Theodolite is an instrument used in surveying to measure horizontal and vertical angles. It is also used for leveling, indirect measure of distances and prolonging a line etc.

How do you use a theodolite?

How to Use a Theodolite Mark the point at which the theodolite will be set up with a surveyor’s nail or a stake. Set up the tripod. Drive the tripod legs into the ground using the brackets on the sides of each leg. Mount the theodolite by placing it atop the tripod, and screw it in place with the mounting knob.

What is a theodolite used for?

Theodolite. The traditional use has been for land surveying, but they are also used extensively for building and infrastructure construction, and some specialized applications such as meteorology and rocket launching .They are also used for measuring height of any object.
