103-423: A surveyor general is an official responsible for government surveying in a specific country or territory. Historically, this would often have been a military appointment, but it is now more likely to be a civilian post. The following surveyor general positions exist, or have existed historically: Surveyor Surveying or land surveying is the technique, profession, art, and science of determining
206-495: A plane table in 1551, but it is thought that the instrument was in use earlier as his description is of a developed instrument. Gunter's chain was introduced in 1620 by English mathematician Edmund Gunter . It enabled plots of land to be accurately surveyed and plotted for legal and commercial purposes. Leonard Digges described a theodolite that measured horizontal angles in his book A geometric practice named Pantometria (1571). Joshua Habermel ( Erasmus Habermehl ) created
309-445: A GPS on large scale surveys makes them popular for major infrastructure or data gathering projects. One-person robotic-guided total stations allow surveyors to measure without extra workers to aim the telescope or record data. A fast but expensive way to measure large areas is with a helicopter, using a GPS to record the location of the helicopter and a laser scanner to measure the ground. To increase precision, surveyors place beacons on
412-486: A baron's possessions; and it also showed to what extent he had under-tenants and the identities of the under-tenants. This was of great importance to William, not only for military reasons but also because of his resolve to command the personal loyalty of the under-tenants (though the "men" of their lords) by making them swear allegiance to him. As Domesday Book normally records only the Christian name of an under-tenant, it
515-415: A definitive reference point as to property holdings across the nation, in case such evidence was needed in disputes over Crown ownership. The Domesday survey, therefore, recorded the names of the new holders of lands and the assessments on which their tax was to be paid. But it did more than this; by the king's instructions, it endeavoured to make a national valuation list, estimating the annual value of all
618-477: A fixed base station and a second roving antenna. The position of the roving antenna can be tracked. The theodolite , total station and RTK GPS survey remain the primary methods in use. Remote sensing and satellite imagery continue to improve and become cheaper, allowing more commonplace use. Prominent new technologies include three-dimensional (3D) scanning and lidar -based topographical surveys. UAV technology along with photogrammetric image processing
721-523: A great political convulsion such as the Norman Conquest, and the following wholesale confiscation of landed estates, William needed to reassert that the rights of the Crown, which he claimed to have inherited, had not suffered in the process. His Norman followers tended to evade the liabilities of their English predecessors. Historians believe the survey was to aid William in establishing certainty and
824-423: A great step forward in the instrument's accuracy. William Gascoigne invented an instrument that used a telescope with an installed crosshair as a target device, in 1640. James Watt developed an optical meter for the measuring of distance in 1771; it measured the parallactic angle from which the distance to a point could be deduced. Dutch mathematician Willebrord Snellius (a.k.a. Snel van Royen) introduced
927-502: A height above sea level. As the surveying profession grew it created Cartesian coordinate systems to simplify the mathematics for surveys over small parts of the Earth. The simplest coordinate systems assume that the Earth is flat and measure from an arbitrary point, known as a 'datum' (singular form of data). The coordinate system allows easy calculation of the distances and direction between objects over small areas. Large areas distort due to
1030-433: A known size. It was sometimes used before to the invention of EDM where rough ground made chain measurement impractical. Historically, horizontal angles were measured by using a compass to provide a magnetic bearing or azimuth. Later, more precise scribed discs improved angular resolution. Mounting telescopes with reticles atop the disc allowed more precise sighting (see theodolite ). Levels and calibrated circles allowed
1133-434: A loop pattern or link between two prior reference marks so the surveyor can check their measurements. Many surveys do not calculate positions on the surface of the Earth, but instead, measure the relative positions of objects. However, often the surveyed items need to be compared to outside data, such as boundary lines or previous survey's objects. The oldest way of describing a position is via latitude and longitude, and often

The book also lists 28,000 slaves , a smaller number than had been enumerated in 1066. In the Domesday Book, scribes' orthography was heavily geared towards French, most lacking k and w, regulated forms for sounds / ð / and / θ / and ending many hard consonant words with e as they were accustomed to do with most dialects of French at
1339-618: A multi frequency phase shift of light waves to find a distance. These instruments eliminated the need for days or weeks of chain measurement by measuring between points kilometers apart in one go. Advances in electronics allowed miniaturization of EDM. In the 1970s the first instruments combining angle and distance measurement appeared, becoming known as total stations . Manufacturers added more equipment by degrees, bringing improvements in accuracy and speed of measurement. Major advances include tilt compensators, data recorders and on-board calculation programs. The first satellite positioning system
1442-411: A plan or map, and the points at the ends of the offset lines could be joined to show the feature. Traversing is a common method of surveying smaller areas. The surveyor starts from an old reference mark or known position and places a network of reference marks covering the survey area. They then measure bearings and distances between the reference marks, and to the target features. Most traverses form
1545-406: A point inside a triangle using the angles cast between the vertices at the unknown point. These could be measured more accurately than bearings of the vertices, which depended on a compass. His work established the idea of surveying a primary network of control points, and locating subsidiary points inside the primary network later. Between 1733 and 1740, Jacques Cassini and his son César undertook
1648-478: A profession. They established the basic measurements under which the Roman Empire was divided, such as a tax register of conquered lands (300 AD). Roman surveyors were known as Gromatici . In medieval Europe, beating the bounds maintained the boundaries of a village or parish. This was the practice of gathering a group of residents and walking around the parish or village to establish a communal memory of

Three sources discuss the goal of the survey : After this had the king a large meeting, and very deep consultation with his council, about this land; how it was occupied, and by what sort of men. Then sent he his men over all England into each shire; commissioning them to find out 'How many hundreds of hides were in the shire, what land the king himself had, and what stock upon
1957-476: A star is determined, the bearing can be transferred to a reference point on Earth. The point can then be used as a base for further observations. Survey-accurate astronomic positions were difficult to observe and calculate and so tended to be a base off which many other measurements were made. Since the advent of the GPS system, astronomic observations are rare as GPS allows adequate positions to be determined over most of
2060-402: A subject of historical debate. Sir Michael Postan , for instance, contends that these may not represent all rural households, but only full peasant tenancies, thus excluding landless men and some subtenants (potentially a third of the country's population). H. C. Darby , when factoring in the excluded households and using various different criteria for those excluded (as well as varying sizes for
2163-495: A theodolite with a compass and tripod in 1576. Johnathon Sission was the first to incorporate a telescope on a theodolite in 1725. In the 18th century, modern techniques and instruments for surveying began to be used. Jesse Ramsden introduced the first precision theodolite in 1787. It was an instrument for measuring angles in the horizontal and vertical planes. He created his great theodolite using an accurate dividing engine of his own design. Ramsden's theodolite represented

In 1859, they were transferred to the new Public Record Office , London. They are now held at the National Archives at Kew. The chest in which they were stowed in the 17th and 18th centuries is also at Kew. In modern times, the books have been removed from
2369-593: A time component. Before EDM (Electronic Distance Measurement) laser devices, distances were measured using a variety of means. In pre-colonial America Natives would use the "bow shot" as a distance reference ("as far as an arrow can slung out of a bow", or "flights of a Cherokee long bow"). Europeans used chains with links of a known length such as a Gunter's chain , or measuring tapes made of steel or invar . To measure horizontal distances, these chains or tapes were pulled taut to reduce sagging and slack. The distance had to be adjusted for heat expansion. Attempts to hold
2472-540: A town, where separately-recorded properties had been demolished to make way for a castle. Early British authors thought that the motivation behind the Survey was to put into William's power the lands, so that all private property in land came only from the grant of King William, by lawful forfeiture. The use of the word antecessor in the Domesday Book is used for the former holders of the lands under Edward , and who had been dispossessed by their new owners. Domesday Book

Typically, much if not all of the drafting and some of the designing for plans and plats of the surveyed property is done by the surveyor, and nearly everyone working in the area of drafting today (2021) utilizes CAD software and hardware both on PC, and more and more in newer generation data collectors in the field as well. Other computer platforms and tools commonly used today by surveyors are offered online by
2678-399: Is a term used when referring to moving the level to take an elevation shot from a different location. To "turn" the level, one must first take a reading and record the elevation of the point the rod is located on. While the rod is being kept in exactly the same location, the level is moved to a new location where the rod is still visible. A reading is taken from the new location of the level and

Most instruments screw onto a tripod when in use. Tape measures are often used for measurement of smaller distances. 3D scanners and various forms of aerial imagery are also used. The theodolite is an instrument for
2884-412: Is an alternate method of determining the position of objects, and was often used to measure imprecise features such as riverbanks. The surveyor would mark and measure two known positions on the ground roughly parallel to the feature, and mark out a baseline between them. At regular intervals, a distance was measured at right angles from the first line to the feature. The measurements could then be plotted on
2987-505: Is because divergent conditions further away from the base reduce accuracy. Surveying instruments have characteristics that make them suitable for certain uses. Theodolites and levels are often used by constructors rather than surveyors in first world countries. The constructor can perform simple survey tasks using a relatively cheap instrument. Total stations are workhorses for many professional surveyors because they are versatile and reliable in all conditions. The productivity improvements from

Static GPS uses two receivers placed in position for a considerable length of time. The long span of time lets the receiver compare measurements as the satellites orbit. The changes as the satellites orbit also provide the measurement network with well conditioned geometry. This produces an accurate baseline that can be over 20 km long. RTK surveying uses one static antenna and one roving antenna. The static antenna tracks changes in

The usual modern scholarly convention is to refer to the work as "Domesday Book" (or simply as "Domesday"), without a definite article. However, the form "the Domesday Book" is also found in both academic and non-academic contexts. The Anglo-Saxon Chronicle states that planning for the survey was conducted in 1085, and the book's colophon states

#17327725890676386-562: The early days of surveying, this was the primary method of determining accurate positions of objects for topographic maps of large areas. A surveyor first needs to know the horizontal distance between two of the objects, known as the baseline . Then the heights, distances and angular position of other objects can be derived, as long as they are visible from one of the original objects. High-accuracy transits or theodolites were used, and angle measurements were repeated for increased accuracy. See also Triangulation in three dimensions . Offsetting

In some counties, one or more principal boroughs formed
7004-748: The ground (about 20 km (12 mi) apart). This method reaches precisions between 5–40 cm (depending on flight height). Surveyors use ancillary equipment such as tripods and instrument stands; staves and beacons used for sighting purposes; PPE ; vegetation clearing equipment; digging implements for finding survey markers buried over time; hammers for placements of markers in various surfaces and structures; and portable radios for communication over long lines of sight. Land surveyors, construction professionals, geomatics engineers and civil engineers using total station , GPS , 3D scanners, and other collector data use land surveying software to increase efficiency, accuracy, and productivity.

From about 1100, references appear to the liber (book) or carta (charter) of Winchester, its usual place of custody; and from the mid-12th to early 13th centuries to the Winchester or king's rotulus ( roll ). To the English, who held the book in awe, it became known as "Domesday Book", in allusion to the Last Judgment and in specific reference to the definitive character of
7416-597: The kingdom concerning the matters contained in the book, and recourse is made to the book, its word cannot be denied or set aside without penalty. For this reason we call this book the "book of judgements", not because it contains decisions made in controversial cases, but because from it, as from the Last Judgement, there is no further appeal. The name "Domesday" was subsequently adopted by the book's custodians, being first found in an official document in 1221. Either through false etymology or deliberate word play ,

In 1960, it was among citations for a real manor which helps to evidence legal use rights on and anchorage into the Crown's foreshore; in 2010, as to proving a manor, adding weight of years to sporting rights (deer and foxhunting); and a market in 2019. Domesday Book is critical to understanding the period in which it was written. As H. C. Darby noted, anyone who uses it can have nothing but admiration for what
7931-613: The local lords. The unit of inquiry was the Hundred (a subdivision of the county, which then was an administrative entity). The return for each Hundred was sworn to by 12 local jurors, half of them English and half of them Norman. What is believed to be a full transcript of these original returns is preserved for several of the Cambridgeshire Hundreds ;– the Cambridge Inquisition – and
8034-464: The measurement of angles. It uses two separate circles , protractors or alidades to measure angles in the horizontal and the vertical plane. A telescope mounted on trunnions is aligned vertically with the target object. The whole upper section rotates for horizontal alignment. The vertical circle measures the angle that the telescope makes against the vertical, known as the zenith angle. The horizontal circle uses an upper and lower plate. When beginning
8137-409: The measurement of vertical angles. Verniers allowed measurement to a fraction of a degree, such as with a turn-of-the-century transit . The plane table provided a graphical method of recording and measuring angles, which reduced the amount of mathematics required. In 1829 Francis Ronalds invented a reflecting instrument for recording angles graphically by modifying the octant . By observing
8240-424: The measuring instrument level would also be made. When measuring up a slope, the surveyor might have to "break" (break chain) the measurement- use an increment less than the total length of the chain. Perambulators , or measuring wheels, were used to measure longer distances but not to a high level of accuracy. Tacheometry is the science of measuring distances by measuring the angle between two ends of an object with
8343-411: The modern systematic use of triangulation . In 1615 he surveyed the distance from Alkmaar to Breda , approximately 72 miles (116 km). He underestimated this distance by 3.5%. The survey was a chain of quadrangles containing 33 triangles in all. Snell showed how planar formulae could be corrected to allow for the curvature of the Earth . He also showed how to resect , or calculate, the position of
8446-403: The name also came to be associated with the Latin phrase Domus Dei ("House of God"). Such a reference is found as early as the late 13th century, in the writings of Adam of Damerham ; and in the 16th and 17th centuries, antiquaries such as John Stow and Sir Richard Baker believed this was the name's origin, alluding to the church in Winchester in which the book had been kept. As a result,
8549-483: The numerous obvious omissions, and ambiguities in presentation. Darby first cites F. W. Maitland 's comment following his compilation of a table of statistics from material taken from the Domesday Book survey, "it will be remembered that, as matters now stand, two men not unskilled in Domesday might add up the number of hides in a county and arrive at very different results because they would hold different opinions as to
8652-672: The other Himalayan peaks. Surveying became a professional occupation in high demand at the turn of the 19th century with the onset of the Industrial Revolution . The profession developed more accurate instruments to aid its work. Industrial infrastructure projects used surveyors to lay out canals , roads and rail. In the US, the Land Ordinance of 1785 created the Public Land Survey System . It formed
8755-582: The record. The word "doom" was the usual Old English term for a law or judgment; it did not carry the modern overtones of fatality or disaster . Richard FitzNeal , treasurer of England under Henry II , explained the name's connotations in detail in the Dialogus de Scaccario ( c. 1179): The natives call this book "Domesday", that is, the day of judgement. This is a metaphor: for just as no judgement of that final severe and terrible trial can be evaded by any subterfuge, so when any controversy arises in
8858-707: The results of the Domesday Survey before the drastic abbreviation and rearrangement undertaken by the scribe of Great Domesday Book. Both volumes are organised into a series of chapters (literally "headings", from Latin caput , "a head") listing the manors held by each named tenant-in-chief directly from the king. Tenants-in-chief included bishops, abbots and abbesses , barons from Normandy , Brittany , and Flanders , minor French serjeants , and English thegns . The richest magnates held several hundred manors typically spread across England, though some large estates were highly concentrated. For example, Baldwin
8961-406: The river-meadows, woodland, pasture, fisheries (i.e. fishing weirs ), water-mills , salt-pans (if by the sea), and other subsidiary sources of revenue; the peasants are enumerated in their several classes; and finally the annual value of the whole, past and present, is roughly estimated. The organisation of the returns on a feudal basis, enabled the Conqueror and his officers to see the extent of
9064-477: The rod and get a reading. The rod can usually be raised up to 25 feet (7.6 m) high, allowing the level to be set much higher than the base of the rod. The primary way of determining one's position on the Earth's surface when no known positions are nearby is by astronomic observations. Observations to the Sun, Moon and stars could all be made using navigational techniques. Once the instrument's position and bearing to
9167-422: The satellite positions and atmospheric conditions. The surveyor uses the roving antenna to measure the points needed for the survey. The two antennas use a radio link that allows the static antenna to send corrections to the roving antenna. The roving antenna then applies those corrections to the GPS signals it is receiving to calculate its own position. RTK surveying covers smaller distances than static methods. This
9270-403: The subject of a separate section. A few have separate lists of disputed titles to land called clamores (claims). The equivalent sections in Little Domesday are called Inuasiones (annexations). In total, 268,984 people are tallied in the Domesday Book, each of whom was the head of a household. Some households, such as urban dwellers, were excluded from the count, but the exact parameters remain
9373-423: The surface of the Earth. Few survey positions are derived from the first principles. Instead, most surveys points are measured relative to previously measured points. This forms a reference or control network where each point can be used by a surveyor to determine their own position when beginning a new survey. Survey points are usually marked on the earth's surface by objects ranging from small nails driven into
9476-412: The survey was completed in 1086. It is not known when exactly Domesday Book was compiled, but the entire copy of Great Domesday appears to have been copied out by one person on parchment (prepared sheepskin), although six scribes seem to have been used for Little Domesday. Writing in 2000, David Roffe argued that the inquest (survey) and the construction of the book were two distinct exercises. He believes
9579-432: The survey's ninth centenary. On this last occasion Great Domesday was divided into two physical volumes, and Little Domesday into three volumes. The project to publish Domesday was begun by the government in 1773, and the book appeared in two volumes in 1783, set in " record type " to produce a partial- facsimile of the manuscript. In 1811, a volume of indexes was added. In 1816, a supplementary volume, separately indexed,
9682-406: The survey, the surveyor points the instrument in a known direction (bearing), and clamps the lower plate in place. The instrument can then rotate to measure the bearing to other objects. If no bearing is known or direct angle measurement is wanted, the instrument can be set to zero during the initial sight. It will then read the angle between the initial object, the theodolite itself, and the item that
9785-536: The telescope aligns with. The gyrotheodolite is a form of theodolite that uses a gyroscope to orient itself in the absence of reference marks. It is used in underground applications. The total station is a development of the theodolite with an electronic distance measurement device (EDM). A total station can be used for leveling when set to the horizontal plane. Since their introduction, total stations have shifted from optical-mechanical to fully electronic devices. Modern top-of-the-line total stations no longer need
9888-467: The time. In a parallel development, around 1100, the Normans in southern Italy completed their Catalogus Baronum based on Domesday Book. The original manuscript was destroyed in the Second World War , but the text survives in printed editions. The manuscripts do not carry a formal title. The work is referred to internally as a descriptio (enrolling), and in other early administrative contexts as
9991-459: The two endpoints. With the Global Positioning System (GPS), elevation can be measured with satellite receivers. Usually, GPS is somewhat less accurate than traditional precise leveling, but may be similar over long distances. When using an optical level, the endpoint may be out of the effective range of the instrument. There may be obstructions or large changes of elevation between the endpoints. In these situations, extra setups are needed. Turning
10094-400: Was not one single hide, nor a yard of land, nay, moreover (it is shameful to tell, though he thought it no shame to do it), not even an ox, nor a cow, nor a swine was there left, that was not set down in his writ. And all the recorded particulars were afterwards brought to him. The primary purpose of the survey was to ascertain and record the fiscal rights of the king. These were mainly: After
10197-590: Was preserved from the late 11th to the beginning of the 13th centuries in the royal Treasury at Winchester (the Norman kings' capital). It was often referred to as the "Book" or "Roll" of Winchester. When the Treasury moved to the Palace of Westminster , probably under King John , the book went with it. The two volumes (Great Domesday and Little Domesday) remained in Westminster, save for temporary releases, until
10300-517: Was published containing Photographic facsimiles of Domesday Book, for each county separately, were published in 1861–1863, also by the government. Today, Domesday Book is available in numerous editions, usually separated by county and available with other local history resources. In 1986, the BBC released the BBC Domesday Project , the results of a project to create a survey to mark
10403-475: Was rebound in 1320, its older oak boards being re-used. At a later date (probably in the Tudor period ) both volumes were given new covers. They were rebound twice in the 19th century, in 1819 and 1869 – on the second occasion, by the binder Robert Riviere and his assistant, James Kew. In the 20th century, they were rebound in 1952, when their physical makeup was examined in greater detail; and yet again in 1986, for
10506-504: Was the US Navy TRANSIT system . The first successful launch took place in 1960. The system's main purpose was to provide position information to Polaris missile submarines. Surveyors found they could use field receivers to determine the location of a point. Sparse satellite cover and large equipment made observations laborious and inaccurate. The main use was establishing benchmarks in remote locations. The US Air Force launched
10609-522: Was to record the annual value of every piece of landed property to its lord, and the resources in land, labour force, and livestock from which the value derived. The name "Domesday Book" came into use in the 12th century. Richard FitzNeal wrote in the Dialogus de Scaccario ( c. 1179) that the book was so called because its decisions were unalterable, like those of the Last Judgment , and its sentence could not be quashed.
