East India Company
The East India Company (EIC) was an English, and later British, joint-stock company founded in 1600 and dissolved in 1874. It was formed to trade in the Indian Ocean region, initially with the East Indies (the Indian subcontinent and Southeast Asia), and later with East Asia. The company seized control of large parts of the Indian subcontinent, colonised parts of Southeast Asia and Hong Kong. At its peak, the company was the largest corporation in the world. The EIC had its own armed forces in the form of the company's three Presidency armies, totalling about 260,000 soldiers, twice the size of the British army at the time. The operations of the company had a profound effect on the global balance of trade, almost single-handedly reversing the trend of eastward drain of Western bullion, seen since Roman times. Originally chartered as the "Governor and Company of Merchants of London Trading into the East-Indies", the company rose to account for half of the world's trade duri ...

Radhanath Sikdar
Radhanath Sikdar (Bengali: রাধানাথ শিকদার; 5 October 1813 – 17 May 1870) was an Indian mathematician who is best known for calculating the height of Mount Everest. He was the first person to calculate the height of Mount Everest, in 1852. Great Trigonometric Survey In 1831, George Everest, the Surveyor General of India, was in the pursuit of a mathematician who had specialised in Spherical Trigonometry, so that they could be a part of the Great Trigonometric Survey. In 1832, under the leadership of Everest, the longitudinal series of the "triangle" survey was completed from Seronj in Madhya Pradesh to Calcutta in West Bengal. While still working on mapping Calcutta, Bengal, Everest had begun his search for a mathematician, and soon enough, John Tytler, a professor of Mathematics at the Hindu College, now known as the Presidency College, recommended his 19-year-old pupil, Radhanath Sikdar. Radhanath, a student of the college since 1824, was one of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Everest
Colonel Sir George Everest CB FRS FRAS FRGS (; 4 July 1790 – 1 December 1866) was a British surveyor and geographer who served as Surveyor General of India from 1830 to 1843. After receiving a military education in Marlow, Everest joined the East India Company and arrived in India at the age of 16. He was eventually made an assistant to William Lambton on the Great Trigonometric Survey, and replaced Lambton as superintendent of the survey in 1823. Everest was largely responsible for surveying the meridian arc from the southernmost point of India north to Nepal, a distance of about , a task that took from 1806 to 1841 to complete. He was made Surveyor General of India in 1830, retiring in 1843 and returning to England. In 1865, the Royal Geographical Society renamed Peak XV – at the time only recently identified as the world's highest peak – to Mount Everest in his honour. Andrew Scott Waugh, his protégé and successor as surveyor general, had been responsible for put ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theodolite
A theodolite () is a precision optical instrument for measuring angles between designated visible points in the horizontal and vertical planes. The traditional use has been for land surveying, but it is also used extensively for building and infrastructure construction, and some specialized applications such as meteorology and rocket launching. It consists of a moveable telescope mounted so it can rotate around horizontal and vertical axes and provide angular readouts. These indicate the orientation of the telescope, and are used to relate the first point sighted through the telescope to subsequent sightings of other points from the same theodolite position. These angles can be measured with accuracies down to microradians or seconds of arc. From these readings a plan can be drawn, or objects can be positioned in accordance with an existing plan. The modern theodolite has evolved into what is known as a total station where angles and distances are measured electronically, and ...

Indian Himalayan Region
The Indian Himalayan Region (abbreviated to IHR) is the section of the Himalayas within the Republic of India, spanning seven Indian states and union territories, namely Ladakh, Jammu and Kashmir, Himachal Pradesh, Uttarakhand, Sikkim, West Bengal and Arunachal Pradesh. The region is responsible for providing water to a large part of the Indian subcontinent and contains various flora and fauna. Physiographically, the Himalayas start from the foothills of south (Sivaliks) and extend up to the Tibetan plateau on the north (Trans-Himalaya). Three major geographical entities, the Himadri (greater Himalaya), Himachal (lesser Himalaya) and the Sivaliks (outer Himalaya), extend almost uninterrupted throughout its length and are separated by major geological fault lines. Mighty but older waterways like the Indus, Sutlej, Kali, Kosi and Brahmaputra cut steep gorges through the main Himalayan range to escape into the Great Plains, establishing their antecedence. The northernmost ran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

William Lambton
Lieutenant-Colonel William Lambton, FRS (c. 1753 – 20 or 26 January 1823) was a British soldier, surveyor, and geographer who began a triangulation survey in 1800-1802 that was later called the Great Trigonometrical Survey of India. His initial survey was to measure the length of a degree of an arc of the meridian so as to establish the shape of the Earth and support a larger scale trigonometrical survey across the width of the peninsula of India between Madras and Mangalore. After triangulating across the peninsula, he continued surveys northwards for more than twenty years. He died during the course of the surveys in central India and is buried at Hinganghat in Wardha district of Maharashtra. He was succeeded by his assistant George Everest. Life Lambton was born around 1753 at Crosby Grange, near Northallerton, in North Yorkshire, the son of a farmer. He was extremely reserved about the details of his family. Even the year of birth is speculated on the basis of an incide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Trigonometrical Survey
The Great Trigonometrical Survey was a project that aimed to survey the entire Indian subcontinent with scientific precision. It was begun in 1802 by the British infantry officer William Lambton, under the auspices of the East India Company.Gill, B. (2001); "THE BIG MAN. Surveying Sir George Everest", in: ''Professional Surveyor Magazine'', Vol. 21 Nr 2. Retrieveonline 8 March 2016. Under the leadership of his successor, George Everest, the project was made the responsibility of the Survey of India. Everest was succeeded by Andrew Scott Waugh, and after 1861, the project was led by James Walker, who oversaw its completion in 1871. Among the many accomplishments of the Survey were the demarcation of the British territories in India and the measurement of the height of the Himalayan giants: Everest, K2, and Kanchenjunga.

North Arcot
North Arcot was a former district in Madras Presidency, acquired by the annexation of the Arcot State in 1855 when its Nawab died without issue. It had Chittoor as its headquarters (currently in Andhra pradesh). On 1 April 1911, the Chittoor district was separated from North Arcot. The remaining district, with Vellore as its headquarters, passed intact into the Madras State of independent India. On 30 September 1989 the district was split into Tiruvannamalai-Sambuvarayar district (present-day Tiruvannamalai district) and North Arcot Ambedkar district (present-day Vellore district). It contained the present day districts of Tiruvannamalai, Vellore, Chittoor, Tirupati, Tirupattur and Ranipet.
