ABSTRACT
Total station is an instrument in which electronic theodolite, electronic distance meter, microprocessor, electronic data collector and storage systems are integrated. It is a combination of an electronic theodolite and an electronic distance meter .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 angle and slope distances.It measures the distances of prism poles mounted with prisms with the help of Laser beam or Infrared rays. These signals are emitted by the instrument EDM and reflected back to instruments by the prism mounted on the prism poles.It uses the technique of remote sensing and GIS.
