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?
Turn the total station to zero degrees on the horizontal axis. Position a reflection in the line of sight of the device. Using the EDM functionality, move the reflector until it is the correct distance away from the instrument. This is the point of the coordinates entered into the system.
What is the total station in civil engineering?
What is a totalstation? A total station combines an electronic theodolite with an electronic distance meter to measure distance. Advances in computer technology enable all the normal survey calculations to be made on-board the instrument, allowing the user to manage data as co-ordinates.
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.
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.
What does the total station measure?
A total station is a theodolite with an integrated distance meter that can measure angles and distances simultaneously.
What is total station and features of total station?
Total stations are capable of measuring angles and distances simultaneously and combine an electronic theodolite with a distance measuring system and a microprocessor. All the components of the electronic theodolite described in the previous lectures are found total stations.
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.
What are the features of total station?
Capabilities of a Total Station
- Monitors : battery status, signal attenuation, horizontal and vertical axes status, collimation factors.
- Computes coordinates.
- Traverse closure and adjustment.
- Topography reductions.
- Remote object elevation.
- Distance between remote points.
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.
When was the total station invented?
The total station was introduced in 1971 and for the first time distance and angle measurements could be recorded by one instrument. The total station is a transit integrated with an EDM, electronic distance meter, which can read slope distances from the instrument to a particular point of land.
What is an EDM total station?
A total station is an electronic theodolite and an electronic distance meter ( EDM ). This combination makes it possible to determine the coordinates of a reflector by aligning the instrument’s cross hairs on the reflector and simultaneously measuring the vertical and horizontal angles and slope distances.
What are the characteristics of total station?
Average of multiple angles measured. Average of multiple distance measured. Horizontal distance. Distance between any two points. All the three coordinates of the observed points. Data collected and processed in a Total Station can be downloaded to computers for further processing. Total station is a compact instrument and weighs 50 to 55 N.
