Theodolites measure horizontal and vertical angles only. ... A total station can measure angles and distances electronically and process trigonometrically to give us, at a minimum, position coordinates in space.

What is theodolite station?

A total station (TS) or total station theodolite (TST) is an electronic/optical instrument used for surveying and building construction.

How total station is more advanced than theodolite?

Total Stations: the New School

This sophisticated device combines all of the functionality of a theodolite with other abilities such as an auto level and electronic distance meter. By using laser pulses, total stations can gather much more accurate information over extreme distances.

Is theodolite the same as transit?

Theodolite vs Transit Level

A theodolite is a precision instrument used for measuring angles both horizontally and vertically. Theodolites can rotate along their horizontal axis as well as their vertical axis. ... A transit is a surveying instrument that also takes accurate angular measurements.

What are the disadvantages of total station?

Disadvantages Of Total Station:
  • The instrument is costlier than other conventional surveying instruments.
  • It might be troublesome for the surveyor to investigate and check the work when surveying.
  • Working with the total station is not so easy, as more skilled surveyors are required to conduct a total station survey.

What can a total station do?

A total station is an optical instrument commonly used in construction, surveying and civil engineering. It is useful for measuring horizontal angles, vertical angles and distance — it does this by analyzing the slope between itself and a specific point. ... Electronic distance meter (EDM)

Can a theodolite measure distances?

A total station consists of a theodolite with a built-in distance meter (distancer), and so it can measure angles and distances at the same time.

What is the least count of theodolite?

Least count means the minimum value that an instrument can read .
  • theodolite: least count is 20"
  • Prismatic compass: least count is 30'
  • least count of levelling staff is 5mm.
  • dumpy level: least count 5mm as it is based on staff reading thats why least count is 5mm.

What is Transit survey?

Transit Definition = A surveying instrument used to measure horizontal and vertical angles.

Which is better theodolite or total station?

Total stations are usually superior to theodolites given their digital integration and more consistent precision. They also can be purchased with a robotic ability, that reduces the number of operators needed, to one.

Are theodolites still used?

Though rarely used nowadays, the theodolite was the predecessor of modern survey instruments. It measures angles in the horizontal and vertical planes, and can be very accurate.

What is reiteration method in surveying?

The method of reiteration is another method of measuring horizontal angles. This method is useful when a number of angles are to be measured at one point. ... This method is useful when a number of angles are to be measured at one point.

How are Clinometers used?

A clinometer is a tool that is used to measure the angle of elevation, or angle from the ground, in a right - angled triangle. You can use a clinometer to measure the height of tall things that you can't possibly reach to the top of, flag poles, buildings, trees.

What is the principle of total station?

Reflectorless total stations can measure distances to any object that is reasonably light in color, to a few hundred meters. Principle: Given the co-ordinate of the instrument position and bearing of a backward station the co-ordinates of any other point can be computed.

What is the least count of telescopic staff?

The least count of a leveling staff is 5 mm.

What is TBM level?

Temporary Bench Mark (TBM) – a point of known height above a pre-defined level. ... The height of any target point is referred to as Reduced Level (RL), because it is reduced to a known datum.

How do you read a Levelling staff?

The staff reading is the reading on the staff at which the horizontal hair appears to cut the staff. A staff reading consists of 4 digits. The first digit represents the whole number of meters, the second digit represents decimeters, and the third, and fourth digits represent millimeters.

Which instrument is used to measure the distance?

To measure distances in a field (for example the length and width of a field), a chain or a measuring tape is used. Two men are required, the back man, holding the zero point of the chain (or the tape), and the front man, holding the other end of the chain.

What is level instrument used for in land 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.

Why it is called total station?

Initially, Total Station was a proper noun introduced by Hewlett-Packard (HP) to promote its Model 3810A around 1975. Probably because of its tunefulness to the ear, surveyors soon applied the term to all theodolites with a built-in EDM unit and total station became a common noun, written without capital letters.

What are the types of total station?

The following are various total station types used in surveying,
  • Mechanical Total Stations. Mechanical Total Station. ...
  • Robotic Total Stations. Robotic Total Station. ...
  • Prism Total Stations. Both the mechanical & robotic total stations come under prism models. ...
  • Reflector.

Which is more accurate GPS or total station?

GPS receiver based systems are ideal for larger jobsites, and accuracy requirements of 8 millimeters (0.03 feet). ... Total Station based systems provide the highest possible degree of accuracy for site positioning, stakeout, grade checking and measurement.
