How does a survey total station work?

A Total Station is a modern surveying instrument that integrates an electronic theodolite with an electronic distance meter. Total Stations use electronic transit theodolites in conjunction with a distance meter to read any slope distance from the instrument to any particular spot.

How is total station used in land surveying?

Enter the coordinates of your first target building corner. Using the ranging pole, find the correct point for the corner and mark it with a profile peg. If the total station is set up at a proposed corner for the building, you can use the distance measuring and ranging pole to find intermediate points along the wall.

How is total station used in construction?

A total station is an electronic/optical instrument used in modern surveying and building construction that uses electronic transit theodolite in conjunction with electronic distance meter (EDM). The instrument is used to measure sloping distance of object to the instrument, horizontal angles and vertical angles.

What is total station and how it works?

A theodolite can be mechanical or electronic. A total station can measure angles and distances electronically and process trigonometrically to give us, at a minimum, position coordinates in space. The horizontal distance, height difference and bearings are calculated automatically.

How does total station measure distance?

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. Today’s electronic total stations all have an opto-electronic distance meter (EDM) and electronic angle scanning.

How does a total station measure elevation?

Determining elevations Carefully level the total station, first using the bullseye level and the tripod legs and then using bubble level and the leveling knobs on the base of the total station. Rotate the telescope through horizontal. If the station is not level, a b will appear in the vertical angle (V) display.

What is the purpose of a total station?

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.

Why is a total station called a 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.

How do you measure area on a total station?

You can proceed by radiating from central station 0. Measure consecutive angles AOB, BOC, COD and DOA. Then measure distances OA, OB, OC and OD from 0 to each corner of the site and calculate the area of each triangle (see step 3, above). The sum of the four triangular areas is the total area.

How do you level a total station?

Procedure for setting up a tripod & leveling Total Station

1. Setup tripod. Open up the tripod and extend the legs.
2. Level the tripod. By changing the length of two legs you used to position the tripod, level the top surface of the tripod using the bulls-eye level.
3. Attach instrument to tribrac.
4. Check alignment over point.

What is a total station in surveying?

A total station is an electronic/optical instrument used in modern surveying and building construction that uses electronic transit theodolite in conjunction with electronic distance meter (EDM).It is also integrated with microprocessor, electronic data collector and storage system.

What is the use of totaltotal station?

Total Station is an equipment used in surveying, designed for measuring horizontal and vertical angles, inclusive of measuring sloping distance of object to the instrument. It is a combination of electronic theodolite and electromagnetic distance measuring (EDM) instrument.

How do you use a total station to measure angle?

Most total stations can measure angle to at least 5 seconds, or 0.0013888 degree. The best procedure when using a Total Station is to set a convenient ” north ” and carry this through the survey by using back sights when the instrument is move. The vertical angle is measure relative to the local vertical ( plumb ) direction.

What is the best procedure when using a total station?

The best procedure when using a Total Station is to set a convenient ” north ” and carry this through the survey by using back sights when the instrument is move.
