Then, to make a survey using this system, proceed in the same way as with other methods of lift with tape or theodolite, though, rather than measuring distances the three readings and the value of the vertical angle shall be taken to the measure in question.
Notably, tachymeter is an instrument simile to the theodolite and which is used to measure angles and distances simultaneously and theodolite, on the other hand, is a mechanical optical measuring instrument of universal cutter used to measure angles, vertical and horizontal, as in these past where achieves outstanding precision; and if used auxiliary tools can even measure distances and unevenness of terrain. It is portable and manual and the theodolite used by this time consists of a telescope mounted on a tripod and two graduated circles, horizontal one and the other vertical, with which the angles with the help of lenses will be measured.
There are different types of taquimetria: the current taquimetria of vertical look, the tangential taquimetria of vertical view and horizontal mira taquimetria.
