    The primary triangulation of the United Kingdom of Roy, Mudge and Yolland was completed by , but was greatly improved by Alexander Ross Clarke who completed a new survey based on Airy 's spheroid in , completing the Principal Triangulation. Art by Ellis Martin After the Ordnance Survey published its first large-scale maps of Ireland in the mids, the Tithe Commutation Act led to calls for a similar six-inch to the mile survey in England and Wales.

    Official procrastination followed, but the development of the railways added to pressure that resulted in the Ordnance Survey Act 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 [16] 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 was by then Director General, and he saw how photography could be used to make maps of various scales cheaply and easily.

    He developed and exploited photozincography , not only to reduce the costs of map production but also to publish facsimiles of nationally important manuscripts. Between and , a facsimile of the Domesday Book was issued, county by county; and a facsimile of the Gough Map was issued in A start was made on mapping the whole country, county by county, at six inches to the mile , In , "twenty-five inch" maps were introduced with a scale of The first edition of the two scales was completed by the s, with a second edition completed in the s and s.

    From till the early s, 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. From the late 19th century to the early s, 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 s, these areas were left blank or incomplete on standard maps. The War Department s, unlike 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.

    City and town mapping, 19th and early 20th century[ edit ] From , the OS began a 6 inch , survey of Ireland for taxation purposes but found this to be inadequate for urban areas and adopted the five-foot scale for Irish cities and towns. In areas where there were no further s, these partially revised "fifty inch" sheets represent the last large-scale revision larger than six-inch of the County Series.

    During World War II, many more maps were created, including: , map of Antwerp , Belgium , map of Brussels , Belgium ,, map of South Africa , map of Italy , map of north-east France , map of the Netherlands with manuscript outline of districts occupied by the German Army.

    After the war, Colonel Charles Close , then Director General, developed a strategy using covers designed by Ellis Martin to increase sales in the leisure market. In O. Crawford was appointed Archaeology Officer and played a prominent role in developing the use of aerial photography to deepen understanding of archaeology. In , 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 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 scale series of maps was introduced.

    Ordnance Survey had outgrown its site in the centre of Southampton made worse by the bomb damage of the Second World War. The bombing during the Blitz devastated Southampton in November and destroyed most of Ordnance Survey's city centre offices.

    Until , 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 the city's court complex.

    The new head office building was designed by the Ministry of Public Buildings and Works for staff, including many new recruits who were taken on in the late s and early 70s as draughtsmen and surveyors.

    Above the industrial areas are extensive office areas. The complex is notable for its concrete mural by sculptor Keith McCarter and the concrete elliptical paraboloid shell roof over the staff restaurant building. In , Ordnance Survey digitised the last of about , maps, making the United Kingdom the first country in the world to complete a programme of large-scale electronic mapping.

    Officially, it is now a civilian organisation with executive agency status. Although there was a small computer section at Ordnance Survey in the s, 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.

    Part of the latter was converted into a new conference centre in , which was used for internal events and also made available for external organisations to hire. Former Ordnance Survey headquarters in Maybush , Southampton , used from until Headquarters in Adanac Park opened in In , OS announced that printing and warehouse operations were to be outsourced, [31] ending over years of in-house printing.

    In April building began of a new head office in Adanac Park on the outskirts of Southampton. Prince Philip officially opened the new headquarters building on 4 October Portlock] proceeded to Wales and Anglesey, to refind stations and erect objects, Lieut.

    Larcom proceeded to Slieve Donard to prepare it for the great instrument, and thus commenced his connection with a survey in which he afterwards filled so important an office. The author, as soon as he had finished his work in Wales, joined him there, and having put up the instrument, began the observations.

    It may be approached by the Shanklin Road for rather more than a mile, then by a bye-road skirting the mountain on the east side. The station is marked by a pile of large coarse stones, having a diameter at base of 16 feet and raised to a height of about 5 feet; this truncated section of a pile has a small quantity of bog turf on its top. The centre stone has a smooth upper surface, with a well-formed hole in it, 2 inches deep and 2 inches in diameter.

    It is level with the surface of the mountain. All station descriptions from Clarke , vol 1, pp. The sub-stratum is mica slate, varying much in hardness.

    A centre stone, 3 feet long, 2. The station, which is on the highest part of the mountain at the east end, is marked by a stone about 2 feet square, having a hole 2 inches deep drilled in its centre, with a pile of stone, 14 feet high and 50 feet in circumference at base, erected over it.

    The station is on the summit of a large carn of small stones known by this name. It is about 24 feet in diameter at the top, and its height above the general surface is about 10 feet. The station is a little to the south-south-west of the present centre of the carn; and the centre stone, which has a well-cut hole, is 6 feet below the surface of the top of the carn, and rests on a bed of small stones.

    The station is on the top of the mountain, and is marked by a pile of turf 15 feet in height, and 50 feet in circumference at base.

    The top of the mountain is long and flat, and exceedingly boggy and wet. The top of the mountain is covered with bog or peat to the depth of nearly 10 feet. In many parts this turf has been abraded to considerable extent, and on the highest of the lumps thus formed is the station. A large hole was dug through the turf, and the frame for supporting the instrument made to rest on the firm ground; this frame was left in position, and a very weighty centre stone was placed at the bottom of the hole; another stone was placed under the pole marking the station.

    It is ridge- formed, exhibiting two precipices, one to the north and the other to the east, the former in the direction of the dip; the station is on an ancient carn near the northeastern angle formed by the junction of these precipices. As a station Cuilcagh is of the first order, commanding a vast number of churches and other points connected with the district triangulation, and thereby assisting to furnish bases for the surveys of about 20 counties.

    This station is on a small rising ground called Sheep Hill, about a quarter of a mile south-east from Ballykelly Church, in the townland of Drummond, parish of Tamlaght, and county of Londonderry. These stations are marked by dots made with the point of a needle in platina wires, eighth of an inch in diameter, run with lead into holes 1. These blocks are laid in cement above other and similar blocks roughly chiselled, and placed on beds of solid masonry.

    The whole at each station is enclosed in a chamber of masonry 6 feet square, with walls 2 feet thick and 3 feet deep, covered over with a lid of flagstone, with bolts and rings passing through them, by which they may be removed with safety to the dots. On the upper surface of the flags cross lines are drawn, with the crosses vertically over the dots.

    This masonry is covered over with a tumulus of earth ; and a circular wall 2 feet thick, with eight internal buttresses, is built as a base for an iron railing 4.
