Mato Theodolite Machine For Surveying ( MET - 202 )

A theodolite is a precision optical instrument for measuring angles between designated visible points in the horizontal and vertical planes. The traditional use has been for land surveying, but they are also used extensively for building and infrastructure construction, and some specialized applications such as meteorology and rocket launching.

It consists of a movable telescope mounted so it can rotate around horizontal and vertical axes and provide angular readouts. These indicate the orientation of the telescope, and are used to relate the first point sighted through the telescope to subsequent sightings of other points from the same theodolite position.Used while making directions plots of the landscape from two standpoints.Two graphing papers are superimposed,providing a scale model of the landscape,or rather the targets in it.
