What is a tachometry? What is it’s used in civil engineering projects?
There are four types of steel stack that generally used in steel stack are as below: Freestanding (Self-supported) steel stack (fig.1) The base support and guyed steel stack (fig.2) The base support and braced steel stack Multi flue stack (fig.3) [caption id="attachment_45199" align="alignnone" widtRead more

Tacheometric is a branch of surveying in which horizontal and vertical distances are
determined by taking angular observation with an instrument known as a tachometer.
Tacheometric surveying is adopted in rough in rough and difficult terrain where direct levelling
and chaining are either not possible or very tedious.
Tacheometric survey also can be used for Railways, Roadways, and reservoirs etc.
Tacheometric surveying is very rapid, and a reasonable contour map can be prepared for
investigation works within a short time on the basis of such survey.
An ordinary transits theodolite fitted with a stadia diaphragm is generally used for tacheometric
surveying.
Uses of Tachometry in civil engineering
See lessTachometry is used for preparation of topographic map where both horizontal and vertical
distances are required to be measured; survey work in difficult terrain where direct methods of
measurements are inconvenient; reconnaissance survey for highways and railways etc.;
Establishment of secondary control points.
