TACHYMETRY Meaning and
Definition
-
Tachymetry is a technique used in surveying and mapping to measure the distance and elevation of points on the Earth's surface with great speed and accuracy. It involves the use of a tachymeter, which is a combination of an electronic theodolite and a distance measuring instrument (DMI), such as a laser rangefinder or an EDM (electronic distance meter).
In tachymetry, the surveyor sets up the tachymeter at a known point and then aims it at a target point. The instrument measures both the horizontal and vertical angles between the two points, and simultaneously determines the distance to the target using the DMI. This allows for the calculation of the coordinates (x, y, and z) of the target point, providing valuable information for creating accurate and detailed maps and plans.
Tachymetry is especially useful in situations where speed and efficiency are important, such as construction and engineering projects. It enables surveyors to quickly obtain precise measurements without the need for lengthy fieldwork and complex mathematical calculations. Additionally, tachymetry is commonly used for applications such as monitoring the stability of structures, determining earthwork volumes, and establishing control networks.
Overall, tachymetry plays a crucial role in modern surveying by providing fast and accurate measurements of distances, elevations, and angles, facilitating the creation of precise and reliable geospatial data.

Etymology of TACHYMETRY
The word "tachymetry" comes from the combination of two Greek roots: "tachys" meaning "swift" or "rapid", and "metron" meaning "measure". The Greek roots reflect the nature and purpose of tachymetry, which is a technique used to measure distances and angles with speed and accuracy.
