Surveying Instruments

Surveying instruments are those type of instruments which are used by surveyors to measure map or plan and analyze the characteristics of land like distances, angles, and elevations. These instruments plays a vital role in ant surveying they gives us the accurate and errorless data for our projects or for planning or designing.

Types of Surveying Instruments :

1. Chain Surveying
2. Tape Surveying
3. Compass Surveying
4. Theodolite Surveying
5. Tacheometric Surveying
6. Levelling Surveying
7. Plan Tabling Surveying
8. Photogrammetry Surveying

Chain Surveying

Chain surveying is the most and the oldest forms of surveying. It involves the measurement of distance and angles using a chain or tape. it is used where high accuracy is not required chains are made from galvanized iron or mild steel of 4 mm Dia, Handle is made with Brass.

Tape Surveying

Tape surveying is similar to chain surveying but here tapes are used, By Tape Surveying we cam measure small distance, it is more accurate than chain surveying.

Compass Surveying

Compass surveying is used to determine the locations of points relative to the magnetic north. it is used to measure angle and then calculate the distance. this type of surveying is useful when conducting surveys in areas without a reliable reference.

Theodolite Surveying

Theodolite surveying is a more advanced form of surveying that utilizes a theodolite instrument for precise angular measurements and provides highly accurate and reliable measurements for complex engineering projects. Theodolite is used to measure horizontal and vertical angles

Tacheometric Surveying

Tacheometric surveying, also known as stadia surveying, it determine the distances and elevations using stadia hairs in the telescope of a theodolite. this survey gives efficient and rapid measurement of distances, making it ideal for large-scale projects

Levelling Surveying

Levelling surveying is used to determine the relative heights of any points on surveying land . It is useful for uniformity and precision in construction projects.

Plan Tabling Surveying

Plan tabling Surveying is also known as graphical surveying it provide a clear visual representation of topography of an area.

Photogrammetry Surveying

Photogrammetry surveying are used in gathering accurate measurements from photographs or images taken through drones, satellite to survey a large area it is useful for assessing land and urban planning.
