75-580: Winnats Pass (or Winnats , as shown on some Ordnance Survey maps) is a hill pass and limestone gorge in the Peak District of Derbyshire , England. The name is a corruption of 'wind gates' due to the swirling winds through the pass. It lies west of the village of Castleton , in the National Trust 's High Peak Estate and the High Peak borough of Derbyshire. The road winds through

150-599: 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 . Paper maps represent only 5% of the company's annual revenue. It produces digital map data, online route planning and sharing services and mobile apps, plus many other location-based products for business, government and consumers. Ordnance Survey mapping

225-615: A cleft, surrounded by high limestone ridges. At the foot of the pass is the entrance to Speedwell Cavern , a karst cave accessed through a flooded lead mine, and which is a popular tourist attraction. In the 1930s, Winnats Pass was the location used for annual access rallies in support of greater access to the moorlands or the Peak District, around the time of the Mass Trespass of Kinder Scout . At their peak these were attended by up to 10,000 people. The permanent closure of

300-656: A close, arranging mountain-top parties with enormous plum puddings . 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,

375-531: A fire in the Tower of London , the headquarters of the survey was moved to Southampton taking over buildings previously occupied by a military orphanage (the Royal Military Asylum ) in 1841, and Yolland was put in charge, but Hall sent him off to Ireland so that when Hall left in 1854 Yolland was again passed over in favour of Major Henry James . Hall was enthusiastic about extending the survey of

450-479: 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

525-585: 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

600-497: A number of occasions since. A local legend is that the pass is haunted by a young couple Alan and Clara who eloped in 1758, only to be robbed and murdered by miners as they headed through Winnats Pass, on their way to Peak Forest Chapel. The miners hid their bodies in a mine shaft where they were discovered 10 years later. 53°20′24″N 1°47′55″W  /  53.34013°N 1.79871°W  / 53.34013; -1.79871 Ordnance Survey The Ordnance Survey ( OS )

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,

750-661: A public objective. For that reason, SOEs primarily operate in the domain of infrastructure (e.g., railway companies), strategic goods and services (e.g., postal services, arms manufacturing and procurement), natural resources and energy (e.g., nuclear facilities, alternative energy delivery), politically sensitive business, broadcasting, banking, demerit goods (e.g., alcoholic beverages ), and merit goods (healthcare). SOEs can also help foster industries that are "considered economically desirable and that would otherwise not be developed through private investments". When nascent or 'infant' industries have difficulty getting investments from

825-495: A regular enterprise, state-owned enterprises are typically expected to be less efficient due to political interference, but unlike profit-driven enterprises they are more likely to focus on government objectives. In Eastern Europe and Western Europe , there was a massive nationalization throughout the 20th century, especially after World War II . In the Eastern Bloc , countries adopted very similar policies and models to

900-477: 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

975-408: A traditional 1:1250 scale paper map. State-owned enterprise The terminology around the term state-owned enterprise is murky. All three words in the term are challenged and subject to interpretation. First, it is debatable what the term "state" implies (e.g., it is unclear whether municipally owned corporations and enterprises held by regional public bodies are considered state-owned). Next, it

1050-583: Is associated with a polygon that represents the area on the ground that the feature covers, in National Grid coordinates. OS MasterMap is offered in themed layers, each linked to a number of TOIDs. 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

1125-562: Is a viable argument for SOEs is debated. SOEs are also frequently employed in areas where the government wants to levy user fees , but finds it politically difficult to introduce new taxation. Next, SOEs can be used to improve efficiency of public service delivery or as a step towards (partial) privatization or hybridization. SOEs can also be a means to alleviate fiscal stress, as SOEs may not count towards states' budgets. Compared to government bureaucracy, state owned enterprises might be beneficial because they reduce politicians' influence over

1200-764: Is approximately 70% of total employment. State-owned enterprises are thus a major factor behind Belarus's high employment rate and a source of stable employment. In most OPEC countries, the governments own the oil companies operating on their soil. A notable example is the Saudi Arabian national oil company , Saudi Aramco , which the Saudi government bought in 1988, changing its name from Arabian American Oil Company to Saudi Arabian Oil Company. The Saudi government also owns and operates Saudi Arabian Airlines , and owns 70% of SABIC as well as many other companies. China's state-owned enterprises are owned and managed by

1275-469: Is contestable under what circumstances a SOE qualifies as "owned" by a state (SOEs can be fully owned or partially owned; it is difficult to determine categorically what level of state ownership would qualify an entity to be considered as state-owned since governments can also own regular stock , without implying any special interference). Finally, the term "enterprise" is challenged, as it implies statutes in private law which may not always be present, and so

1350-617: Is highlighted in the predominant local terminology, with SOEs in Canada referred to as a " Crown corporation ", and in New Zealand as a " Crown entity ". The term " government-linked company " (GLC) is sometimes used, for example in Malaysia , to refer to private or public (listed on a stock exchange) corporate entities in which the government acquires a stake using a holding company . The two main definitions of GLCs are dependent on

1425-537: 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,

1500-481: 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

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

1800-644: 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

As of 2017 , China has more SOEs than any other country, and the most SOEs among large national companies. China's SOEs perform functions such as: contributing to central and local governments revenues through dividends and taxes, supporting urban employment, keeping key input prices low, channeling capital towards targeted industries and technologies, supporting sub-national redistribution to poorer interior and western provinces, and aiding

1950-547: 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

2025-589: 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

Khazanah Nasional Berhad provided

2175-1019: The USSR. Governments in Western Europe, both left and right of centre, saw state intervention as necessary to rebuild economies shattered by war. Government control over natural monopolies like industry was the norm. Typical sectors included telephones , electric power , fossil fuels , iron ore , railways , airlines , media , postal services , banks , and water . Many large industrial corporations were also nationalized or created as government corporations, including, among many others: British Steel Corporation , Equinor , and Águas de Portugal . A state-run enterprise may operate differently from an ordinary limited liability corporation. For example, in Finland, state-run enterprises ( liikelaitos ) are governed by separate laws. Even though responsible for their own finances, they cannot be declared bankrupt ;

2250-449: The base of Winnats Pass, close to Speedwell Cavern, suggests that a contemporary underwater cleft or canyon once existed within the active reef which caused the build up of shelly and crinoidal remains at its base. All these sediments were subsequently buried together under Namurian sandstones and shales in the subsequent Upper Carboniferous period. They were subsequently uplifted, but were only re-exposed by periglacial erosion towards

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

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

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

2700-522: 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

Pricing of licenses to OS MasterMap data depends on the total area requested, the layers licensed, the number of TOIDs in the layers, and the period in years of the data usage. OS MasterMap can be used to generate maps for a vast array of purposes and maps can be printed from OS MasterMap data with detail equivalent to

3075-438: 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.

Crawford was appointed Archaeology Officer and played a prominent role in developing the use of aerial photography to deepen understanding of archaeology. In 1922, devolution in Northern Ireland led to the creation of the Ordnance Survey of Northern Ireland (OSNI) and the independence of the Irish Free State led to the creation of the Ordnance Survey of Ireland , so

However, the narrowness of the road and its maximum gradient of over 28% has caused it to be closed to buses, coaches and vehicles over 7.5 tonnes (7.4 long tons; 8.3 short tons) in weight. The road regularly features in the Tour of the Peak cycle race each autumn. The gorge of Winnats Pass

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

3525-592: The negotiations fail, the owner can decide about the implementation. It turns out that when cost-reducing innovations do not harm quality significantly, then private firms are to be preferred. Yet, when cost-reductions may strongly reduce quality, state-owned enterprises are superior. Hoppe and Schmitz (2010) have extended this theory in order to allow for a richer set of governance structures, including different forms of public-private partnerships . SOEs are common with natural monopolies , because they allow capturing economies of scale while they can simultaneously achieve

3600-738: The north of England to a scale of 1:2,500. 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 . The primary triangulation of the United Kingdom of Roy, Mudge and Yolland was completed by 1841, but was greatly improved by Alexander Ross Clarke who completed

The organisation remains fully owned by the UK government and retains many of the features of a public organisation. In September 2015 the history of the Ordnance Survey was the subject of a BBC Four TV documentary entitled A Very British Map: The Ordnance Survey Story . On 10 June 2019

3825-535: 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. Each measurement made by theodolite during

However, the government cannot necessarily predict which industries would qualify as such 'infant industries', and so the extent to which this

3975-417: 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

4050-428: The proportion of the corporate entity a government owns. One definition purports that a company is classified as a GLC if a government owns an effective controlling interest (more than 50%), while the second definition suggests that any corporate entity that has a government as a shareholder is a GLC. The act of turning a part of government bureaucracy into a SOE is called corporatization . In economic theory ,

4125-451: The question of whether a firm should be owned by the state or by the private sector is studied in the theory of incomplete contracts developed by Oliver Hart and his co-authors. In a world in which complete contracts were feasible, ownership would not matter because the same incentive structure that prevails under one ownership structure could be replicated under the other ownership structure. Hart, Shleifer, and Vishny (1997) have developed

4200-410: The rest of Europe in preparation for its invasion . 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

4275-498: 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

Conversely, they might be detrimental because they reduce oversight and increase transaction costs (such as monitoring costs, i.e., it is more difficult and costly to govern and regulate an autonomous SOE than it is the public bureaucracy). Evidence suggests that existing SOEs are typically more efficient than government bureaucracy, but that this benefit diminishes as services get more technical and have less overt public objectives. Compared to

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,

4500-521: 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

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,

Thus, SOEs are known under many other terms: state-owned company, state-owned entity, state enterprise, publicly owned corporation, government business enterprise, government-owned company, government controlled company, government controlled enterprise, government-owned corporation, government-sponsored enterprise , commercial government agency, state-privatised industry public sector undertaking, or parastatal, among others. In some Commonwealth realms , ownership by The Crown

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

5400-457: 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

5475-404: Was once thought to have originated as a giant collapsed cavern ; however, this idea has since been superseded. Winnats Pass can be seen to cut steeply down through Lower Carboniferous limestone rocks. These were formed approximately 340 million years ago as a reef fringing a shallow lagoon, with deeper water beyond. The presence of a small outcrop of fossiliferous rock (known as 'beach beds') at

5550-501: 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

5625-670: 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
