Total Station Advantages,Disadvantage and Precaution

Introduction To Total Station

The main instrument for surveyors on site today is the “total station”. A total station is a combination of an electronic theodolite, an electronic distance measuring device (EDM) and a micro processor with memory unit. This combination makes possible to determine the coordinates of a reflector aligning the instruments cross hairs on the reflector and simultaneously measuring the vertical and horizontal angles and slope distances. A micro processor in the instrument takes care of recording, readings and the necessary computation.

Advantages Of Total Station

  • Quick setting of the instrument on the tripod using laser plummet.
  • On- board area computation programme to compute the area of the field.
  • Local language support.
  • Full GIS creation(using mapinfo software).
  • Automation of old maps.
  • Greater accuracy in area computation.
  • Graphical view of plots and land for quick
  • Integration of data base.
  • The area computation at any user required scale.
  • The field jobs are finished, the map of the area with dimensions is ready after data transfer
  • It’s reduce the time & also it’s measure up to 3 to 5 Km distance.

Disadvantages Of Total Station

  • It may be difficult for the surveyor to look over and check the work while surveying.
  • the instrument is costly. And conducting surveys using total station, skilled personnel are required.
  • for an over all check of the survey, it will be necessary to return to the office and prepare the drawings using appropriate software.

   PRECAUTION TO BE TAKEN WHILE  USING A TOTAL STATION:

  • Use both hands to hold the total station handle.
  • Set up the tripod as stable as possible.
  • Do not move or carry a tripod with the total station fixed on it, except for centering.
  • Store the battery pack with the battery discharged.
  • Do not over tighten any of the clamp screws.
  • Take maximum care when the tribrach is removed from the total station.
