The height of the instrument in surveying refers to the elevation of the line of sight of the surveying instrument, typically a level or total station, above a reference point, usually the ground or a benchmark. It is essential for accurate measurements as it determines how high the instrument is positioned relative to the points being surveyed. This height is crucial in calculating elevations of points and ensuring the precision of leveling work. Surveyors often measure it from the bottom of the instrument to the ground or a specific reference point.

How do you find reduced level?
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.

How do you calcuate height of instrument in surveying?
When surveying using a "level" instrument , the "level" instrument is set-up and adjusted to level by adjusting the screws. When surveying you have an instrument person and a rod person. When trying to find the height of the instrument, the rod person places there rod over a "known" elevation, either a benchmark or a temporary benchmark that has a known elevation. To get the height of the instrument, you need to "shoot" the level to the rod person holding the rod on the known elevation, this is called the "Backsight". This elevation will be read by the instrument person, and recorded in the survey field book. This value backsight elevation will then be added to the known elevation of the benchmark or the temporary benchmark, to get the height of instrument. HI = known elevation + BS Height

What word means an instrument for measuring height?
The word that means an instrument for measuring height is "altimeter." An altimeter is commonly used in aviation and outdoor activities to determine altitude above sea level. It can also refer to devices used in surveying to measure vertical distances.

What is Line of Collimation in surveying?
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.
