THEODOLITE Meaning and
Definition
-
A theodolite is a precise and sophisticated surveying instrument used for measuring horizontal and vertical angles. It consists of a telescope mounted on a rotating base that allows for accurate angle measurements. The device typically consists of a sighting tube, which is positioned horizontally and vertically through a series of adjustable angles.
The theodolite is used by surveyors, engineers, and cartographers for various purposes, including measuring points, determining elevations, and mapping terrain. By measuring precise angles, the theodolite allows for the calculation of distances and the creation of accurate maps and drawings.
The instrument is equipped with features such as leveling screws and a bubble level to ensure accurate measurements by compensating for uneven surfaces and ensuring the device is perpendicular to the ground. Some theodolites also include electronic distance measurement capabilities, known as EDM, which offer more precise measurements over longer distances.
Theodolites come in various types, including transit theodolites, which have a telescope that moves only in a vertical plane, and total stations, which integrate electronic distance measurements with angle measurements. These instruments are widely used in various fields, such as construction, engineering, and land surveying.
In summary, the theodolite is a highly accurate and versatile instrument used in surveying and mapping to measure horizontal and vertical angles, determine distances, and create precise drawings and maps.

Etymology of THEODOLITE
The word "theodolite" is derived from two Greek words: "theo" (θεός), meaning "god", and "dolos" (δόλος), meaning "craft" or "device".
The term was coined in the late 16th century by English mathematician and surveyor Leonard Digges. He chose the name "theodolite" as he believed it was a "divine instrument" due to its precision and accuracy in measuring angles and distances. Theodolites were considered a significant advancement in surveying technology during that time and were primarily used for mapping and construction purposes.
