The Principal Triangulation of Britain was the first high-precision triangulation survey of the whole of Great Britain and Ireland, carried out between 1791 and 1853 under the auspices of the Board of Ordnance. The aim of the survey was to establish precise geographical coordinates of almost 300 significant landmarks which could be used as the fixed points of local topographic surveys from which maps could be drawn. In addition there was a purely scientific aim in providing precise data for geodetic calculations such as the determination of the length of meridian arcs and the figure of the Earth. Such a survey had been proposed by William Roy (1726–1790) on his completion of the Anglo-French Survey but it was only after his death that the Board of Ordnance initiated the trigonometric survey, motivated by military considerations in a time of a threatened French invasion. Most of the work was carried out under the direction of Isaac Dalby, William Mudge and Thomas Frederick Colby, but the final synthesis and report (1858) was the work of Alexander Ross Clarke. The survey stood the test of time for a century, until the Retriangulation of Great Britain between 1935 and 1962.
Ordnance Survey Ireland was the national mapping agency of the Republic of Ireland. It was established on 4 March 2002 as a body corporate. It was the successor to the former Ordnance Survey of Ireland. It and the Ordnance Survey of Northern Ireland (OSNI) were themselves the successors to the Irish operations of the British Ordnance Survey. OSI was part of the Irish public service. OSI was headquartered at Mountjoy House in the Phoenix Park in Dublin, which had previously been the headquarters of the British Ordnance Survey in Ireland until 1922.

The Great Trigonometrical Survey of India was a project that aimed to carry out a survey across the 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. 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.

Golden Square, in Soho, the City of Westminster, London, is a mainly hardscaped garden square planted with a few mature trees and raised borders in Central London flanked by classical office buildings. Its four approach ways are north and south but it is centred 125 metres east of Regent Street and double that NNE of Piccadilly Circus. A small block south is retail/leisure street Brewer Street. The square and its buildings have featured in many works of literature and host many media, advertising and public relations companies that characterise its neighbourhood within Soho.
Lieutenant Colonel William Yolland CB, FRS FRSA was an English military surveyor, astronomer and engineer, and was Britain's Chief Inspector of Railways from 1877 until his death. He was a redoubtable campaigner for railway safety, often in the face of strong opposition, at a time when railway investment was being directed towards the expansion of the networks rather than the prevention of accidents. He was a member of the three-man committee of inquiry into the Tay Bridge disaster.

Robert Abraham (1773–1850) was an English building surveyor and later architect in London. He was the son of a builder and was educated as a surveyor as a pupil of James Bowen. He turned to architecture after 1818, and was chiefly employed by the leading Roman Catholic families in England, including the Duke of Norfolk and the Earl of Shrewsbury.
The Ordnance Survey (OS) is the national mapping agency for Great Britain. The agency's name indicates its original military purpose, which was to map Scotland in the wake of the Jacobite rising of 1745. There was also a more general and nationwide need in light of the potential threat of invasion during the Napoleonic Wars. Since 1 April 2015, the Ordnance Survey has operated as Ordnance Survey Ltd, a government-owned company, 100% in public ownership. The Ordnance Survey Board remains accountable to the Secretary of State for Science, Innovation and Technology. It was also a member of the Public Data Group.
Colonel Robert Kearsley Dawson was an English surveyor and cartographer of the Corps of Royal Engineers.
William Mudge (1762–1820) was an English artillery officer and surveyor, born in Plymouth, an important figure in the work of the Ordnance Survey.
Christopher (1786–1855) and John Greenwood (1791–1840) were brother cartographers who produced large-scale maps of England and Wales in the 1820s.
Dunnose is a cape on the Isle of Wight in the English Channel. The headland is visible from well out to sea, and is used in navigation. It has twice been used as the base point for a triangulation of Great Britain. The line of accurately surveyed points running north from Dunnose to Clifton in Yorkshire provide the basis for triangulation to determine the positions of all other locations in Britain.
In 1746, the French-born British surveyor and cartographer John Rocque produced two maps of London and the surrounding area. The better known of these has the full name A Plan of the Cities of London and Westminster, and Borough of Southwark: it is a map of Georgian London to a scale of 26 inches to a mile, surveyed by John Rocque, engraved by John Pine, and published in 1746. It consists of 24 sheets and measures 3.84 m × 2.01 m. Taking nearly ten years to survey, engrave and publish, it has been described as "a magnificent example of cartography ... one of the greatest and most handsome plans of any city".
