To find the reduced level (RL) of a point in surveying, you start with a known benchmark (a point with a fixed elevation) and measure the height of the instrument (HI) by adding the benchmark's elevation to the height of the instrument above that benchmark. Then, you conduct a leveling survey by measuring the staff readings at the point of interest. The reduced level is calculated by subtracting the staff reading from the height of the instrument (RL = HI - staff reading). This method ensures accurate elevation data for various surveying applications.
Surveying instrument of high precision, can measure both vertical and horizontal angles, unlike a level telescope which is limited to the flat angles. The name is believed to come from the Greek- meaning, The Eye of God.
The instrument used for measuring slope angles is called an inclinometer or clinometer. An inclinometer typically measures the angle of a slope relative to a horizontal plane, while a clinometer can also be used for measuring angles of elevation or depression. Both tools are essential in fields such as surveying, geology, and construction.
taking readings using theodolite keeping the vertical circle of the instrument on left side of the observer is called a face left observation and to measure horizontal angle the instrument is rotated(swing) in horizontal plane with respect to the vertical axis in a clockwise direction called rigt swing.

George Washington received his first surveying instruments from his older half-brother, Lawrence Washington. Lawrence gifted George with a set of surveying tools when George was a teenager, which sparked his interest in surveying and mapping.

The main classes of surveying are geodetic surveying, topographic surveying, cadastral surveying, construction surveying, and hydrographic surveying. Geodetic surveying deals with large areas and high accuracy measurements for mapping the Earth's surface. Topographic surveying focuses on determining the natural and man-made features of a specific area. Cadastral surveying involves demarcating property boundaries. Construction surveying is done to guide the construction of infrastructure and buildings, while hydrographic surveying is used to map underwater features.
The line of collimation in surveying is an imaginary line that extends from the objective lens of a surveying instrument to the crosshairs in the telescope. It helps ensure the instrument is properly aligned and level for accurate measurements. By keeping the line of collimation straight and horizontal, surveyors can minimize errors in their readings.
The Visayas are islands in the Philippines. As to 'instrument' - you need to give more information? Musical instrument? Surveying instrument? Or something else?
The process of measuring property to determine the boundaries of a person's land is called land surveying. It involves determining the size and shape of a piece of land and identifying its boundaries using specialized equipment and techniques. Land surveying is crucial for establishing property lines, resolving boundary disputes, and creating accurate maps.
