Chain (length)
The chain (abbreviated ch) is a unit of length equal to 66 feet (22 yards), used in both the US customary and Imperial unit systems. It is subdivided into 100 links. (PDF) There are 10 chains in a furlong, and 80 chains in one statute mile. In metric terms, it is 20.1168 m long. By extension, chainage (running distance) is the distance along a curved or straight survey line from a fixed commencing point, as given by an odometer. The chain has been used since the early 17th century in England, and was brought by British settlers during the colonial period to other countries around the globe. In the United Kingdom, there were 80 chains to the mile, but until the early nineteenth century the Scottish and Irish customary miles were longer than the statute mile; consequently a Scots chain was about 74 (imperial) feet, an Irish chain 84 feet. These longer chains became obsolete following the adoption of the imperial system of units in 1824. In India, "metric chains" of exac ...

Imperial Units
The imperial system of units, imperial system or imperial units (also known as British Imperial or Exchequer Standards of 1826) is the system of units first defined in the British Weights and Measures Act 1824 and continued to be developed through a series of Weights and Measures Acts and amendments. The imperial system developed from earlier English units as did the Comparison of the imperial and US customary measurement systems, related but differing system of United States customary units, customary units of the United States. The imperial units replaced the Winchester measure, Winchester Standards, which were in effect from 1588 to 1825. The system came into official use across the British Empire in 1826. By the late 20th century, most nations of the former empire had metrication, officially adopted the metric system as their main system of measurement, but imperial units are still used alongside metric units in the United Kingdom and in some other parts of the former empi ...

Statute Measure
Weights and Measures Acts are acts of the British Parliament determining the regulation of weights and measures. It also refers to similar royal and parliamentary acts of the Kingdoms of England and Scotland and the medieval Welsh states. The earliest of these were originally untitled but were given descriptive glosses or titles based upon the monarch under whose reign they were promulgated. Several omnibus modern acts have the short title " Weights and Measures Act" and are distinguished by the year of their enactment. Background There have been many laws concerned with weights and measures in the United Kingdom or parts of it over the last 1,000 or so years. The acts may catalogue lawful weights and measures, prescribe the mechanism for inspection and enforcement of the use of such weights and measures and may set out circumstances under which they may be amended. Modern legislation may, in addition to specific requirements, set out circumstances under which the incumb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bridge Miles And Chains
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or railway) without blocking the path underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge, dating from the 13th century BC, in the Peloponnese is one of the oldest arch bridges in existence and use. Etymology The ''Oxford English Dictionary'' traces the origin of the word ''bridge' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Land Ordinance Of 1785
The Land Ordinance of 1785 was adopted by the United States Congress of the Confederation on May 20, 1785. It set up a standardized system whereby settlers could purchase title to farmland in the undeveloped west. Congress at the time did not have the power to raise revenue by direct taxation, so land sales provided an important revenue stream. The Ordinance set up a survey system that eventually covered over three-quarters of the area of the continental United States. The earlier Land Ordinance of 1784 was a resolution written by Thomas Jefferson calling for Congress to take action. The land west of the Appalachian Mountains, north of the Ohio River and east of the Mississippi River was to be divided into ten separate states. However, the 1784 resolution did not define the mechanism by which the land would become states, or how the territories would be governed or settled before they became states. The Ordinance of 1785 put the 1784 resolution in operation by providing a mecha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Continental Congress
The Continental Congress was a series of legislature, legislative bodies, with some executive function, for the Thirteen Colonies of British America, Great Britain in North America, and the newly declared United States before, during, and after the American Revolutionary War. The Continental Congress refers to both the First Continental Congress, First and Second Continental Congress, Second Congresses of 1774–1781 and at the time, also described the Congress of the Confederation of 1781–1789. The Confederation Congress operated as the first federal government until being replaced following ratification of the Constitution of the United States, U.S. Constitution. Until 1785, the Congress met predominantly at what is today Independence Hall in Philadelphia, though it was relocated temporarily on several occasions during the Revolutionary War and the Philadelphia campaign, fall of Philadelphia. The First Continental Congress convened in Philadelphia in 1774 in response to esc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cadastral
A cadastre or cadaster ( ) is a comprehensive recording of the real estate or real property's metes and bounds, metes-and-bounds of a country.Jo Henssen, ''Basic Principles of the Main Cadastral Systems in the World,'/ref> Often it is represented graphically in a cadastral map. In most countries, legal systems have developed around the original administrative systems and use the cadastre to define the dimensions and location of land parcels described in legal documentation. A land parcel or cadastral parcel is defined as "a continuous area, or more appropriately volume, that is identified by a unique set of homogeneous property rights". Cadastral surveys document the Boundary (real estate), boundaries of land ownership, by the production of documents, diagrams, sketches, plans (''plats'' in the US), charts, and maps. They were originally used to ensure reliable facts for land valuation and taxation. An example from early England is the Domesday Book in 1086. Napoleon establish ...

Gunter's Chain
Gunter's chain (also known as Gunter's measurement) is a distance-measuring device used for surveying. It was designed and introduced in 1620 by English clergyman and mathematician Edmund Gunter (1581–1626). It enabled plots of land to be accurately surveyed and plotted, for legal and commercial purposes. Gunter developed an actual measuring chain of 100 links. These, the chain and the link, became statutory measures in England and subsequently the British Empire. Description The chain is divided into 100 links, usually marked off into groups of 10 by brass rings or tags which simplify intermediate measurement. Each link is thus long. A quarter chain, or 25 links, measures and thus measures a rod (or pole). Ten chains measure a furlong and 80 chains measure a statute mile. Gunter's chain reconciled two seemingly incompatible systems: the traditional English land measurements, based on the number four, and decimals based on the number 10. Since an acre measured 10 ...

Britannia (atlas)
''Britannia'' is the title of each of three atlases created in England the late 16th and mid 18th centuries, describing some or all of the British Isles. These are the books published by William Camden (in 1586, reprinted 1693) and Richard Blome (in 1673) and John Ogilby (in 1675). Of the three, Ogilby's is probably best known because it was the first to use measured distances. Camden's ''Britannia'' In 1577, William Camden (1551–1623) began his great work ''Britannia'', a topographical and historical survey of all of Great Britain and Ireland. His stated intention was to "restore antiquity to Britaine, and Britain to his antiquity". The first edition, written in Latin, was published in 1586. It proved very popular, and ran through five further Latin editions, of 1587, 1590, 1594, 1600 and 1607, each greatly enlarged from its predecessor in both textual content and illustrations. The 1607 edition included for the first time a full set of English county maps, based on the surve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Ogilby
John Ogilby, Ogelby, or Oglivie (17 November 16004 September 1676) was a Scottish translator, impresario, publisher and cartographer. He was probably at least a half-brother to James Ogilvy, 1st Earl of Airlie, though neither overtly acknowledged this. Ogilby's most-noted works include translations of the works of Virgil and Homer, and his version of the Fables of Aesop. Ogilby established Ireland's first theatre in Werburgh Street, Dublin, and following the Restoration, that country's first Theatre Royal. Ogilby played a significant part in arrangements for the coronation of King Charles II. Following the Great Fire of 1666, Ogilby's large-scale map of the City of London was founded on precise survey work, and his ''Britannia'' is the first road atlas of England and Wales to be based on surveys and measurements, and drawn to scale. Life Childhood and youth (1600–1618) John Ogilby's birthplace and parentage are historically uncertain; most early biographies of Ogil ...

Edmund Gunter
Edmund Gunter (158110 December 1626), was an English clergyman, mathematician, geometer and astronomer of Welsh descent. He is best remembered for his mathematical contributions, which include the invention of the Gunter's chain, the #Gunter's quadrant, Gunter's quadrant, and the #Gunter's scale, Gunter's scale. In 1620, he invented the first successful analogue device which he developed to calculate logarithmic tangents. He was mentorship, mentored in mathematics by Reverend Henry Briggs (mathematician), Henry Briggs and eventually became a Gresham Professor of Astronomy, from 1619 until his death.

Polymath
A polymath or polyhistor is an individual whose knowledge spans many different subjects, known to draw on complex bodies of knowledge to solve specific problems. Polymaths often prefer a specific context in which to explain their knowledge, but some are gifted at explaining abstractly and creatively. Embodying a basic tenet of Renaissance humanism that humans are limitless in their capacity for development, the concept led to the notion that people should embrace all knowledge and develop their capacities as fully as possible. This is expressed in the term Renaissance man, often applied to the Intellectual giftedness, gifted people of that age who sought to develop their abilities in all areas of accomplishment: intellectual, artistic, social, physical, and spiritual. Etymology The word polymath derives from the Ancient Greek, Greek roots ''poly-'', which means "much" or "many," and ''manthanein'', which means "to learn." Plutarch wrote that the Ancient Greek Muses, muse P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
