Total station


Total station is a combination of theodolite, level, EDM, microprocessor with a specific memory. Total station integrates the functions of a theodolite for measuring angles, an EDM for measuring distances, digital data & data recorder. From this instrument distance, angle, height difference, co-ordinate, area, bearing, perimeter etc. can be easily measured. Its accuracy was in part per million (ppm). It can measured slope distance directly. Topcon, sokia, pentex, Nicon, Leica, Stonex, etc. are the model of total station.


Features and Uses of Total station:

    1. Total Solution for surveying work 
    2.  Most accurate of user friendly 
    3.  Gives position of point (X, Y, Z) W.R.T. known point 
    4.  EDM was fitted inside Telescope 
    5.  on board memory to store data
    6.  Digital display 
    7.  Compatibility with computers
    8. can be used for carry layout



Functions of Total station:

1. It simultaneously measures angle of distance  & record 
2.  Correcting the measured distance with.   

 prism constant
 Atmospheric pressure
 Temperature 
 curvature of earth   
 Refraction correction 

3.  Computing the point elevation   
4.  Comparing the coordinates of every point  
5.   Remote elevation measurement
6.  Remote distance measurement
7. Area calculation  
 8. Data transferring facility from instrument to computer and computer to       Instrument 
 9. Format of conversion of units.

Note : -    Non-prism Totalstation

  • Low accuracy than prism total station. 
  • Can't measure more distance (up to 2 km only)

This type of surveying is suitable for survey of small extent on open ground having few simple details.  The principles of chain surveying are triangulation. As we know triangle is the simplest 2D figure whose area can be calculated easily and it is only the figure which can be plotted without any angle. According to this principle the area of surv

PRINCIPLES AND CLASSIFICATIONS OF SURVEYING 1      Basic Principles of surveying a) Working from whole to part :  The main principle of surveying whether plane or geodetic is to work from the whole to the part. This implies a precise control surveying as the first consideration followed by subsidiary detail surveying. Due to this, error arising in a place is limited to small space and is not spread (localization of error). It prevents the accumulation of errors. If survey is carried out from the part to the whole, the errors would expand to greater magnitude and the scale of the survey will be destroy beyond control.   for example: Area to be surveyed contain number of spread control points called primary control point was establish with a high level of precision. To fill the gap between them Secondary cps established with lesser precision than the primary CPs (Control Points).  b) Locating of a point with reference of two other points: There must be at least two refere

Introduction of surveying  1.  Surveying and mapping. Surveying is the science and art of determining the relative positions of various points above, on or below the surface of the earth. The relative positions are determined by measuring horizontal distances, vertical distances (elevations), horizontal angles and vertical angles accurately using various surveying instruments. After taking the measurements in the field, computations are done and the plans and maps are prepared in the office. These plans and maps are used for planning of engineering works, marking of boundaries, computations of areas and volumes, and various other purposes. Surveying also includes the art of setting out or locating the points on the ground from the plan or map . S o, surveying can be done by different methods some of them are listed belo w: 1.   1.      Land surveying. 2.      Engineering surveying. 3.      Mining surveying. 4.      Hydrographic surveying. 5.      Geodetic surveying.
