What Is Total Station And Who Uses Them

December 13, 2017 | Author: Zoe Gan | Posted in Engineering

Total stations are electronic/optical instruments 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.

The instrument is used to measure sloping distance of object to the instrument, horizontal angles and vertical angles. This Microprocessor unit enables for computation of data collected to further calculate the horizontal distance, coordinates of a point and reduced level of point.

Data collected from total station can be downloaded into computer/laptops for further processing of information.

Total stations are surveying equipments used mainly by land surveyors and civil engineers, either to record features as in topographic surveying or to set out features (such as roads, houses or boundaries).

Total stations are also used by archaeologists to record excavations and by police, crime scene investigators, private accident reconstructionists and insurance companies to take measurements of scenes.

Capability of total stations:

Microprocessor unit in total station processes the data collected to compute:

1) Average of multiple angles measured.

2) Average of multiple distances measured.

3) Horizontal distance.

4) Distance between any two points.

5) Elevation of objects and

6) All the three coordinates of the observed points.

Data collected and processed in total stations can be downloaded to computers for further processing.

When using the total stations, the instrument is mounted on a tripod and is levelled by operating levelling screws. Within a small range instrument is capable of adjusting itself to the level position. Then vertical and horizontal reference directions are indexed using onboard keys. It is possible to set required units for distance, temperature and pressure. Surveyor can select measurement mode like fine, coarse, single or repeated.

When target is sighted, horizontal and vertical angles as well as sloping distances are measured and by pressing appropriate keys they are recorded along with point number. Heights of instrument and targets can be keyed in after measuring them with tapes. Then processor computes all the various information about the point and displays on screen.

There are so many functionalities to choose from when purchasing total stations. The more functions a total station has, or the more sophisticated it is, the higher the price. However, it is advisable to purchase your total stations from a reliable, experienced and knowledgeable company who has been in the industry for a very long time. Kodi Engineering, a company specializing in surveying instruments and precision laser instruments for the construction and engineering field, can definitely help you with your projects. Kodi Engineering caters to different market needs and is well diverse to serve your ever-changing needs.

If you are making a purchase decision about total stations, it is wise to make a list of the types of surveys to be conducted and the accuracy required. However, a total station must be operated by a skilled person, if not the output of data will be garbage.
