Total Station in Civil Engineering
WHAT IS TOTAL STATION? – A total station is a combination of an electronic theodolite and an electronic distance meter (EDM).
This combination makes it possible to determine the coordinates of a reflector by 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 computations. The data is easily transferred to a computer where it can be used to generate a map.
Total station manufactured by M / s Wild Heerbrugg.
Fundamental measurements:
When aimed at an appropriate target, a total station measures three parameters
- The rotation of the instrument’s optical axis from the instrument north in a horizontal plane: i.e. Horizontal Angle.
- The inclination of the optical axis from the local ve rtical i.e. Vertical Angle.
- The distance between instruments and target i.e. Slope Distance.
