Total station features and data recording steps

Short answer

Total station features include integrated angle and distance measurement, onboard coordinate computation, data storage, and built-in programs. Data recording involves creating a job, entering station and atmospheric data, orienting backsight, measuring each point with point ID and code, storing readings, and finally downloading for processing.

Describe the features of total station. Mention the steps of data recording in any instruments.

Features of a total station

  • Electronic theodolite, EDM and microprocessor in one instrument; measures horizontal angle, vertical angle and slope distance together.
  • Angle accuracy of 1″–5″; EDM range of a few km with a prism and reflectorless modes.
  • Automatic computation of horizontal distance, elevation difference and coordinates with corrections for curvature, refraction, temperature and pressure.
  • Dual-axis compensator, laser plummet and onboard programs (resection, setting out, area, remote height).
  • Internal memory or memory card, and data transfer by cable, USB or Bluetooth.

Steps of data recording

  1. Set up and level the instrument over the station; measure the instrument height.
  2. Create a new job or file; enter the station name, instrument height, prism height, and the atmospheric parameters.
  3. Orient the instrument by backsighting a known point (set the azimuth or coordinates).
  4. Sight the target prism and press the measure key to record the horizontal angle, vertical angle and distance.
  5. Enter the point number and code (feature description) for every shot, and store it in memory.
  6. Repeat for all points and check the closing readings.
  7. Download the data to a computer and process it (editing, adjustment and plotting).
