Total station, features, data recording points

Short answer

A total station is an integrated electronic theodolite, EDM, and microprocessor that measures angles and distances and computes coordinates. Features include precise angle sensing, long-range EDM with reflectorless mode, dual-axis compensator, and onboard data storage. When recording, ensure correct station and atmospheric data, backsight orientation, and unique point numbers with codes.

What is total station? Write some typical features of total station. You are recording the data in the total station mention the three points which are kept in mind.

A total station is an instrument that combines an electronic theodolite, an electronic distance meter (EDM) and a microprocessor, and measures horizontal angle, vertical angle and slope distance together, then computes coordinates and stores them.

Typical features

  • Electronic angle measurement (1″–5″) and EDM range up to several km with prism.
  • Reflectorless (laser) distance measurement on surfaces.
  • Dual-axis compensator, laser plummet and built-in programs (resection, setting out, area, remote elevation).
  • Memory card or internal memory, USB/Bluetooth data transfer.
  • Automatic corrections for curvature, refraction, temperature and pressure.
  • Robotic models with automatic target tracking.

Three points to keep in mind when recording data

  1. Correct set-up data: enter the correct station name/coordinates, instrument height, prism height and prism constant, and the atmospheric (temperature, pressure) data.
  2. Backsight/orientation: the instrument must be oriented by sighting a known point, and the orientation must be checked.
  3. Unique point number and code: each point is stored with a unique point number and a feature code so that data can be processed correctly; also check the storage capacity and battery before starting, and transfer the data safely.
