The British Geological Survey was founded in 1835 as the Ordnance Geological Survey under Henry De la Beche , and remained a branch of the Ordnance Survey until 1965. At the same time, the uneven quality of the English and Scottish maps was being improved by engravers under Benjamin Baker . By the time Colby retired in 1846,

Hall was enthusiastic about extending the survey of

295-479: A large range of paper maps and digital mapping products. The Ordnance Survey's flagship digital product, launched in November 2001, is OS MasterMap , a database that records, in one continuous digital map, every fixed feature of Great Britain larger than a few metres. Every feature is given a unique TOID (TOpographical IDentifier), a simple identifier that includes no semantic information. Typically, each TOID

354-585: A new survey based on Airy 's spheroid in 1858, completing the Principal Triangulation . The following year, he completed an initial levelling of the country. After the Ordnance Survey published its first large-scale maps of Ireland in the mid-1830s, the Tithe Act 1836 led to calls for a similar six-inch to the mile survey in England and Wales . Official procrastination followed, but

413-501: A proportion of its profits to the Treasury. In 2010, OS announced that printing and warehouse operations were to be outsourced, ending over 200 years of in-house printing. The Frome-based firm Butler, Tanner and Dennis (BT&D) secured its printing contract. As already stated, large-scale maps had not been printed at the Ordnance Survey since the common availability of geographical information systems (GISs), but, until late 2010,

472-477: A second edition of the town plans: by 1909 only fourteen places had paid for updates. The review determined that revision of 1:2500 mapping should proceed apace. The most detailed mapping of London was the OS's 1:1056 survey between 1862 and 1872, which took 326 sheets to cover the capital; a second edition (which needed 759 sheets because of urban expansion) was completed and brought out between 1891 and 1895. London

In September 2010, the layers were: Topography: Integrated transport network: Imagery Address: Address 2: ITN was withdrawn in April 2019 and replaced by OS MasterMap Highways Network The Address layers were withdrawn in about 2016 with

767-537: Is the national mapping agency for Great Britain. The agency's name indicates its original military purpose (see ordnance and surveying ), 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,

826-481: Is usually classified as either " large-scale " (in other words, more detailed) or "small-scale". The Survey's large-scale mapping comprises 1:2,500 maps for urban areas and 1:10,000 more generally. (The latter superseded the 1:10,560 "six inches to the mile " scale in the 1950s.) These large scale maps are typically used in professional land-use contexts and were available as sheets until the 1980s, when they were digitised . Small-scale mapping for leisure use includes

885-629: The Department for Business, Energy and Industrial Strategy (BEIS) appointed Steve Blair as the Chief Executive of the Ordnance Survey. The Ordnance Survey supported the launch of the Slow Ways initiative, which encourages users to walk on lesser used paths between UK towns. On 7 February 2023, ownership of Ordnance Survey Ltd passed to the newly formed Department for Science, Innovation and Technology . The Ordnance Survey produces

By 10 February 2011 virtually all staff had relocated to the new "Explorer House" building and the old site had been sold off and redeveloped. Prince Philip officially opened the new headquarters building on 4 October 2011. On 22 January 2015 plans were announced for

During World War II, many more maps were created, including: After the war, Colonel Charles Close , then Director General, developed a strategy using covers designed by Ellis Martin to increase sales in

1121-644: The Pilgrims' Way in the North Downs labelled the wrong route, but the name stuck. Similarly, the spelling of Scafell and Scafell Pike copied an error on an earlier map, and was retained as this was the name of a corner of one of the Principal Triangles , despite "Scawfell" being the almost universal form at the time. Colby believed in leading from the front, travelling with his men, helping to build camps and, as each survey session drew to

1180-547: The 1:25,000 "Explorer" series, the 1:50,000 "Landranger" series and the 1:250,000 road maps. These are still available in traditional sheet form. Ordnance Survey maps remain in copyright for 50 years after their publication. Some of the Copyright Libraries hold complete or near-complete collections of pre-digital OS mapping. The origins of the Ordnance Survey lie in the aftermath of the Jacobite rising of 1745 . Prince William, Duke of Cumberland realised that

1239-589: The British Army did not have a good map of the Scottish Highlands to locate Jacobite dissenters such as Simon Fraser, 11th Lord Lovat so that they could be put on trial. In 1747, Lieutenant-Colonel David Watson proposed the compilation of a map of the Highlands to help in pacifying the region. In response, King George II charged Watson with making a military survey of the Highlands under

This route was probably followed by the Vandals , Alans and Suebi when they invaded Hispania in the 5th century, and with certainty by Charlemagne and other less famed Frankish expeditions against Pamplona . The Basque section of the road was still in use when Napoleon invaded Spain between 1808 and 1814 and was known for

1357-522: The centre of Southampton (made worse by the bomb damage of the Second World War). The bombing during the Blitz devastated Southampton in November 1940 and destroyed most of the Ordnance Survey's city centre offices . Staff were dispersed to other buildings and to temporary accommodation at Chessington and Esher, Surrey, where they produced 1:25000 scale maps of France, Italy, Germany and most of

1416-481: The city's court complex. The new head office building was designed by the Ministry of Public Building and Works for 4000 staff, including many new recruits who were taken on in the late 1960s and early 1970s as draughtsmen and surveyors. The buildings originally contained factory-floor space for photographic processes such as heliozincography and map printing, as well as large buildings for storing flat maps. Above

1475-591: The command of the Duke of Cumberland. Among Watson's assistants were William Roy , Paul Sandby and John Manson. The survey was produced at a scale of 1 inch to 1,000 yards (1:36,000) and included " the Duke of Cumberland's Map " (primarily by Watson and Roy), now held in the British Library . Roy later had an illustrious career in the Royal Engineers (RE), rising to the rank of General, and he

1534-563: The development of the railways added to pressure that resulted in the Ordnance Survey Act 1841 ( 4 & 5 Vict. c. 30). This granted a right to enter property for the purpose of the survey. Following a fire at its headquarters at the Tower of London in 1841 the Ordnance Survey relocated to a site in Southampton and was in disarray for several years, with arguments about which scales to use. Major-General Sir Henry James

By 1810, one-inch-to-the-mile maps of most of the south of England were completed, but they were withdrawn from sale between 1811 and 1816 because of security fears. By 1840, the one-inch survey had covered all of Wales and all but

A Roman pace was two steps, left plus right, and was conventionally set at 5 Roman feet (0.296m), resulting in a Roman mile of approximately 1,480 metres (0.92 miles). Below are the original Latin ablative forms for sites along route 13, followed by

1711-522: The early 1940s, the OS produced many "restricted" versions of the County Series maps and other War Department sheets for War Office purposes, in a variety of large scales that included details of military significance such as dockyards, naval installations, fortifications and military camps. Apart from a brief period during the disarmament talks of the 1930s, these areas were left blank or incomplete on standard maps. The War Department 1:2500s, unlike

Celestial , by sculptor Keith McCarter and the concrete elliptical paraboloid shell roof over the staff restaurant building. In 1995, the Ordnance Survey digitised the last of about 230,000 maps, making the United Kingdom the first country in the world to complete a programme of large-scale electronic mapping. By

1947-438: The late 1990s technological developments had eliminated the need for vast areas for storing maps and for making printing plates by hand. Although there was a small computer section at the Ordnance Survey in the 1960s, the digitising programme had replaced the need for printing large-scale maps, while computer-to-plate technology (in the form of a single machine) had also rendered the photographic platemaking areas obsolete.

In areas where there were no further 1:2500s, these partially revised "fifty inch" sheets represent the last large-scale revision (larger than six-inch) of the County Series. The County Series mapping was superseded by

In 1855, the Board of Ordnance was abolished and the Ordnance Survey was placed under the War Office together with the Topographical Survey and the Depot of Military Knowledge. Eventually in 1870 it was transferred to the Office of Works .

2360-535: The original Ordnance Survey pulled its coverage back to Great Britain. In 1935, the Davidson Committee was established to review the Ordnance Survey's future. The new Director General, Major-General Malcolm MacLeod , started the retriangulation of Great Britain , an immense task involving the erection of concrete triangulation pillars ("trig points") on prominent hilltops as infallible positions for theodolites.

However, Arias may not have taken account of earlier work indicating that distances were measured between the edges of administrative areas of named settlements as opposed to centre-to-centre, thereby explaining supposed distance shortfalls and providing additional useful data on the approximate sizes of such areas.

2478-417: The production of six-inch maps of Ireland was complete. This had led to a demand for similar treatment in England, and work was proceeding on extending the six-inch map to northern England, but only a three-inch scale for most of Scotland. When Colby retired, he recommended William Yolland as his successor, but he was considered too young and the less experienced Lewis Alexander Hall was appointed. After

Until 1969, the Ordnance Survey largely remained at its Southampton city centre HQ and at temporary buildings in the suburb of Maybush nearby, when a new purpose-built headquarters was opened in Maybush adjacent to the wartime temporary buildings there. Some of the remaining buildings of the original Southampton city-centre site are now used as part of

2596-498: The retriangulation was repeated no fewer than 32 times. The Davidson Committee's final report set the Ordnance Survey on course for the 20th century. The metric national grid reference system was launched and a 1:25000-scale series of maps was introduced. The one-inch maps continued to be produced until the 1970s, when they were superseded by the 1:50000-scale series – as proposed by William Roy more than two centuries earlier. The Ordnance Survey had outgrown its site in

2655-399: The six northernmost counties of England. Surveying was hard work. For instance, Major Thomas Colby , the longest-serving Director General of the Ordnance Survey, walked 586 mi (943 km) in 22 days on a reconnaissance in 1819. In 1824, Colby and most of his staff moved to Ireland to work on a six-inches-to-the-mile (1:10,560) valuation survey. The survey of Ireland, county by county,

2714-521: The six-inch standard was adopted in Great Britain for the un-surveyed northern counties and the 1:1056 scale also began to be adopted for urban surveys. Between 1842 and 1895, some 400 towns were mapped at 1:500 (126 inches), 1:528 (120 inches, "10 foot scale") or 1:1056 (60 inches), with the remaining towns mapped at 1:2500 (~25 inches). In 1855, the Treasury authorised funding for 1:2500 for rural areas and 1:500 for urban areas. The 1:500 scale

2773-477: The standard issue, were contoured . The de-classified sheets have now been deposited in some of the Copyright Libraries, helping to complete the map-picture of pre-Second World War Britain. From 1824, the OS began a 6-inch (1:10,560) survey of Ireland for taxation purposes but found this to be inadequate for urban areas and adopted the five-foot scale (1:1056) for Irish cities and towns. From 1840,

2832-524: The survey are to endeavour to obtain the correct orthography of the names of places by diligently consulting the best authorities within their reach. The name of each place is to be inserted as it is commonly spelt, in the first column of the name book and the various modes of spelling it used in books, writings &c. are to be inserted in the second column, with the authority placed in the third column opposite to each. Whilst these procedures generally produced excellent results, mistakes were made: for instance,

The most likely imperial patron—if the work had one—would have been Caracalla . The British section is known as the Iter Britanniarum , and can be described as the ' road map ' of Roman Britain . There are 15 such itineraries in

2950-422: The two scales was completed by the 1890s, with a second edition completed in the 1890s and 1900s. From 1907 till the early 1940s, a third edition (or "second revision") was begun but never completed: only areas with significant changes on the ground were revised, many two or three times. Meanwhile, publication of the one-inch to the mile series for Great Britain was completed in 1891. From the late 19th century to

3009-470: Was a forgery by Charles Bertram that provided much spurious information on Roman Britain , including "itineraries" that overlapped the legitimate Antonine Itineraries, sometimes with contradicting information. Its authenticity was not seriously challenged until 1845, and it was still cited as an authoritative source until the late nineteenth century. By then, its false data had infected almost every account of ancient British history, and had been adopted into

Roy's birthplace near Carluke in South Lanarkshire is today marked by a memorial in the form of a large OS trig point . By 1791, the Board received the newer Ramsden theodolite (an improved successor to

He developed and exploited photozincography , not only to reduce the costs of map production but also to publish facsimiles of nationally important manuscripts. Between 1861 and 1864, a facsimile of the Domesday Book was issued, county by county; and a facsimile of the Gough Map

Colby was not only involved in the design of specialist measuring equipment. He also established a systematic collection of place names, and reorganised the map-making process to produce clear, accurate plans. Place names were recorded in "Name Books", a system first used in Ireland. The instructions for their use were: The persons employed on

3245-457: Was considered more 'rational' than 1:528 and became known as the "sanitary scale" since its primary purpose was to support establishment of mains sewerage and water supply. However, a review of the Ordnance Survey in 1892 found that sales of the 1:500 series maps were very poor and the Treasury declined to fund their continuing maintenance, declaring that any revision or new mapping at this scale must be self-financing. Very few towns and cities saw

3304-449: Was issued in 1870. From the 1840s, the Ordnance Survey concentrated on the Great Britain " County Series ", modelled on the earlier Ireland survey. A start was made on mapping the whole country, county by county, at six inches to the mile (1:10,560). In 1854, "twenty-five inch" maps were introduced with a scale of 1:2500 (25.344 inches to the mile) and the six inch maps were then based on these twenty-five inch maps. The first edition of

3363-402: Was largely responsible for the British share of the work in determining the relative positions of the French and British royal observatories. This work was the starting point of the Principal Triangulation of Great Britain (1783–1853), and led to the creation of the Ordnance Survey itself. Roy's technical skills and leadership set the high standard for which the Ordnance Survey became known. Work

3422-501: Was published, detailing the county of Kent , with Essex following shortly afterwards. The Kent map was published privately and stopped at the county border, while the Essex maps were published by the Ordnance Survey and ignored the county border, setting the trend for future Ordnance Survey maps. During the next 20 years, about a third of England and Wales was mapped at the same scale (see Principal Triangulation of Great Britain ) under

3481-670: Was unusual in that land registration on transfer of title was made compulsory there in 1900. The 1:1056 sheets were partially revised to provide a basis for HM Land Registry index maps and the OS mapped the whole London County Council area (at 1:1056) at national expense. Placenames from the second edition were used in 2016 by the GB1900 project to crowd-source an open-licensed gazetteer of Great Britain. From 1911 onwards – and mainly between 1911 and 1913 – the Ordnance Survey photo-enlarged many 1:2500 sheets covering built-up areas to 1:1250 (50.688 inches to
