# basic surveying calculations

Introduction:

Surveying is the practice of determining the relative position of points on, above, or below the surface of the earth. It is used to gather information about the physical features of a piece of land or property for various purposes such as construction, mapping, and engineering. Surveyors use a variety of instruments and techniques to measure distances, angles, and elevations accurately. Basic surveying calculations are fundamental to the work of a surveyor. Distance Calculation

Distance calculation is an essential aspect of surveying. The distance between two points can be measured using different methods depending on the available tools and terrain. One of the most common methods is the use of a tape measure or a chain. To measure long distances, surveyors use instruments such as a total station, which uses electronic distance measurement (EDM) technology to calculate distances accurately.

Another method of measuring distance is by using triangulation. This involves measuring the angles between a fixed point and two other points whose distance is to be calculated. Using trigonometric principles, the distance can be calculated based on the known angle and the length of one of the sides.

Angle Calculation

Angle calculation is another critical aspect of surveying. Angles are measured in degrees, minutes, and seconds. Surveyors use several instruments to measure angles, including theodolites and transit levels. These instruments allow surveyors to measure vertical and horizontal angles accurately.

One of the most common ways of measuring an angle is by setting up a theodolite at a location and sighting a target object. The angle between the vertical axis of the theodolite and the line of sight to the object is then measured. Theodolites also have a horizontal circle that can be used to measure horizontal angles.

Elevation Calculation

Elevation calculation is the process of determining the height of a point above sea level. Surveyors use various techniques to calculate elevations, including trigonometry, leveling, and GPS. Leveling involves the use of a level instrument, such as a spirit level or an optical level, to measure the difference in height between two points.

Trigonometry can also be used to calculate elevation, especially when measuring heights that are hard to access. This technique involves using the Pythagorean theorem to calculate the height of a point based on the length of the hypotenuse and the angle of elevation.

### How do you calculate surveying?

Surveying is calculated using a variety of methods, instruments and techniques depending on what needs to be measured. The most common measurements in surveying are distance, angle and elevation. Distance can be measured using tape measures, chains or more advanced instruments such as total stations. Angle is usually measured with theodolites or transit levels, while elevations can be calculated using trigonometry, leveling or GPS.

What are the basics of surveying?
