How do you survey a total station?
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 are the basic calculations of total station?
Explanation: The basic calculations of total stations include horizontal distance, vertical distance, co-ordinate distance in which, slope distance is used in horizontal distance calculations. It is obtained directly from the total station equipment.
How do I take levels in total station?
Procedure for setting up a tripod & leveling Total Station
- Setup tripod. Open up the tripod and extend the legs.
- 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.
- Attach instrument to tribrac.
- Check alignment over point.
How do surveyors measure distance?
This practice consists of surveyors measuring distances by measuring the angle between two ends of an object with a known size to establish the distance measurements, and tools such as a theodolite are used to determine the specific angle between those objects.
What is the accuracy of total station?
A typical total station can measure distances up to 1,500 meters (4,900 ft) with an accuracy of about 1.5 millimeters (0.059 in) ± 2 parts per million. Reflectorless total stations can measure distances to any object that is reasonably light in color, up to a few hundred meters.
What are the three components of a total station?
Components of a Total Station It consists of a distance measuring instrument (EDM), an angle measuring instrument (Theodolite) and a simple microprocessor.
What is SD on a total station?
Distance difference. Distance Displayed item. SD: S-O SD=measured slope distance – slope distance of Setout data.
How do you calculate elevation in surveying?
The elevation is calculated by subtracting the foresight rod reading from the height of instrument. A foresight is the elevation reading of a point of unknown elevation. The rod could be moved to other points as shown in Figure 13, and similar calculations would determine the elevations of these points.
What angle is measured in total station?
The best quality total stations are capable of measuring angles to 0.5 arc-second. Inexpensive “construction grade” total stations can generally measure angles to 5 or 10 arc-seconds.
What are the three methods of distance measurement in surveying?
Linear Measurements
- Horizontal distance.
- Vertical Distance.
How can total station be used to measure distance?
When calculating the horizontal distance between points, this difference also needs to be taken into consideration. Because the total station gives a true slope distance, the horizontal difference is simply H = s * cos α (see figure below).
What is working principle of total station?
The total station is an electronic theodolite (transit) integrated with an electronic distance meter (EDM), plus internal data storage and/or external data collector. The purpose of any survey is to prepare maps, control points formed a basic requirement for the preparation of these maps.
What is HR in total station?
in the screen that you will need to know the. meaning of are: hr = Height of reflector above ground. hi = Height of Total Station above survey point.
What is BS and FS in survey?
From each levelling station, measure a backsight (BS) and a foresight (FS) , except: at starting point A, where you have only a backsight measurement. at ending point B, where you have only a foresight measurement.
What is a total station in surveying?
A total station is an optical surveying instrument that uses electronics to calculate angles and distances. It combines the functions of a theodolite with that of a transit level and electronic distance meter (EDM).
Which is the best manual for total station?
