How did the government measure mount Everest in 1852?

During Great Trigonometric Survey they used theodolites to measure Mount Everest.


How were theodolites useful in old times?

Theodolites were used in old times for surveying, mapping, and construction projects. They helped measure horizontal and vertical angles accurately, allowing for precise calculations of distances and elevations. Theodolites were essential tools for creating detailed maps, designing infrastructure, and aligning structures with precision.


What is the difference between transit and non transit thiodolite?

Transit theodolites (or just 'Transits') are those in which the telescope can rotate in a complete circle in the vertical plane, whereas the rotation in the same plane is restricted to a semi-circle for non-transit theodolites


What is vernier theodolite?

In Vernier Theodolites, vernier are used for taking the readings. These theodolites are most commonly used in the general works. Most of the general Theodolites can read upto 20"


What are the permanent adjustments of a theodolite?

Most theodolites have no "permanent" adjustments, since they are used to measure angles, both horizontal and vertical.


Why do surveyors use theodolites?

Surveyors use theodolites to measure angles in the horizontal and vertical planes with high accuracy. This allows them to determine directions and elevations of various points on the land they are surveying. The data collected from theodolites is essential for creating maps, construction projects, boundary delineation, and other surveying applications.


What method is used to measure the lines used to measure the lines of the longitude and latitude to find the exact location?

The method used to measure lines of longitude and latitude to determine exact location is called geodetic surveying. It involves the use of specialized instruments such as theodolites and GPS receivers to accurately measure angles and distances on the Earth's surface. These measurements are then used to calculate the precise coordinates of a particular location.


What do they measure Mount Everest?

Today they use satalites to measure the height of Mount Everest. When the mountain was first measured by Andrew Waugh, the British Surveyor General of India in 1847 they used a very large Theodolites weighing up tp 1100lbs and needing 12 men to carry them.

Methods used to determine the height of mount Everest?

In 1856, the Great Trigonometrical Survey of India measured Mount Everest using theodolites each weighing 500 kg (1,100 lb) and requiring 12 men to carry, to measure heights as accurately as possible. Today it is measured using satellite and GPS.


What is geodetic theodolite?

A geodetic theodolite is a precise surveying instrument used to measure horizontal and vertical angles in geodetic surveying. It is designed for high-accuracy measurements required in geodetic surveying applications such as mapping, construction, and infrastructure development. Geodetic theodolites are typically equipped with electronic distance measurement capabilities for increased accuracy and efficiency.
