Anglo-French Survey (1784–1790)
The Anglo-French Survey (1784–1790) was the geodetic survey to measure the relative position of the Royal Observatory, Greenwich, Royal Greenwich Observatory and the Paris Observatory via triangulation (surveying), triangulation. The English operations, executed by William Roy, consisted of the measurements of bases at Hounslow Heath (1784) and Romney Marsh (1787), the measurements of the angles of the triangles (1787–1788) and finally the calculation of all the triangles (1788–1790). The survey is very significant as the first precise survey within Britain, and the forerunner of the work of the Ordnance Survey which was founded in 1791, one year after Roy's death. Cassini's memoir Late in life, when he was 57, Roy was granted the opportunity to establish his lasting reputation in the world of geodesy. The opening came from a completely unexpected direction. In 1783 the director of the Paris Observatory, César-François Cassini de Thury, Cassini de Thury, addressed a me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geodetic Survey
Geodesy or geodetics is the science of measuring and representing the Figure of the Earth, geometry, Gravity of Earth, gravity, and Earth's rotation, spatial orientation of the Earth in Relative change, temporally varying Three-dimensional space, 3D. It is called planetary geodesy when studying other astronomical body, astronomical bodies, such as planets or Natural satellite, circumplanetary systems. Geodynamics, Geodynamical phenomena, including crust (geology), crustal motion, tides, and polar motion, can be studied by designing global and national Geodetic control network, control networks, applying space geodesy and terrestrial geodetic techniques, and relying on Geodetic datum, datums and coordinate systems. Geodetic job titles include geodesist and geodetic surveyor. History Geodesy began in pre-scientific Classical antiquity, antiquity, so the very word geodesy comes from the Ancient Greek word or ''geodaisia'' (literally, "division of Earth").

Dunkirk
Dunkirk ( ; ; ; Picard language, Picard: ''Dunkèke''; ; or ) is a major port city in the Departments of France, department of Nord (French department), Nord in northern France. It lies from the Belgium, Belgian border. It has the third-largest French harbour. The population of the commune in 2019 was 86,279. Etymology and language use The name of Dunkirk derives from West Flemish 'dune' or 'dun (fortification), dun' and 'church', thus 'church in the dunes'. A smaller town 25 km (15 miles) farther up the Flemish coast originally shared the same name, but was later renamed Oostduinkerke(n) in order to avoid confusion. Until the middle of the 20th century, French Flemish (the local variety of Dutch language, Dutch) was commonly spoken. History Middle Ages A fishing village arose late in the tenth century, in the originally flooded coastal area of the English Channel south of the Western Scheldt, when the area was held by the County of Flanders, Counts of Flanders, va ...

English Channel
The English Channel, also known as the Channel, is an arm of the Atlantic Ocean that separates Southern England from northern France. It links to the southern part of the North Sea by the Strait of Dover at its northeastern end. It is the busiest Sea lane, shipping area in the world. It is about long and varies in width from at its widest to at its narrowest in the Strait of Dover."English Channel". ''The Columbia Encyclopedia'', 2004. It is the smallest of the shallow seas around the continental shelf of Europe, covering an area of some . The Channel aided the United Kingdom in becoming a naval superpower, serving as a natural defence against invasions, such as in the Napoleonic Wars and in the World War II, Second World War. The northern, English coast of the Channel is more populous than the southern, French coast. The major languages spoken in this region are English language, English and French language, French.

Heathrow (hamlet)
Heathrow or Heath Row was a wayside hamlet along a minor country lane called Heathrow Road in the ancient parish of Harmondsworth, Middlesex, England, on the outskirts of what is now Greater London. Its buildings and all associated holdings were demolished, along with almost all of the often grouped locality of The Magpies in 1944 for the construction of the new London Airport, which would later assume the name of Heathrow after 1967. The name Heathrow described its layout: a lane, on one side smallholdings and farms of fields and orchards which ran for a little over a , on the other, until the 1819 Inclosure for farmland, common land: a mixture of pasture, hunting and foraging land on less fertile heath. Akin to Sipson Green it was a scattered agricultural locality of Harmondsworth. The two lightly populated places dotted the brickearth-over-gravel soils in the east of Harmondsworth which historically butted on to Hounslow Heath. Yards from the lane, while the heath existe ...

Theodolite
A theodolite () is a precision optical instrument for measuring angles between designated visible points in the horizontal and vertical planes. The traditional use has been for land surveying, but it is also used extensively for building and infrastructure construction, and some specialized applications such as meteorology and rocket launching. It consists of a moveable telescope mounted so it can rotate around horizontal and vertical axes and provide angular readouts. These indicate the orientation of the telescope, and are used to relate the first point sighted through the telescope to subsequent sightings of other points from the same theodolite position. These angles can be measured with accuracies down to microradians or seconds of arc. From these readings a plan can be drawn, or objects can be positioned in accordance with an existing plan. The modern theodolite has evolved into what is known as a total station where angles and distances are measured electronicall ...

Cannon In Roy Grove Hampton
A cannon is a large-caliber gun classified as a type of artillery, which usually launches a projectile using explosive chemical propellant. Gunpowder ("black powder") was the primary propellant before the invention of smokeless powder during the late 19th century. Cannons vary in gauge, effective range, mobility, rate of fire, angle of fire and firepower; different forms of cannon combine and balance these attributes in varying degrees, depending on their intended use on the battlefield. A cannon is a type of heavy artillery weapon. The word ''cannon'' is derived from several languages, in which the original definition can usually be translated as ''tube'', ''cane'', or ''reed''. The earliest known depiction of cannons may have appeared in Song dynasty China as early as the 12th century; however, solid archaeological and documentary evidence of cannons do not appear until the 13th century. In 1288, Yuan dynasty troops are recorded to have used hand cannons in combat, and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Workhouse
In Britain and Ireland, a workhouse (, lit. "poor-house") was a total institution where those unable to support themselves financially were offered accommodation and employment. In Scotland, they were usually known as Scottish poorhouse, poorhouses. The earliest known use of the term ''workhouse'' is from 1631, in an account by the mayor of Abingdon, Oxfordshire, Abingdon reporting that "we have erected within our borough a workhouse to set poorer people to work". The origins of the workhouse can be traced to the Statute of Cambridge 1388, which attempted to address the labour shortages following the Black Death in England by restricting the movement of labourers, and ultimately led to the state becoming responsible for the support of the poor. However, mass unemployment following the end of the Napoleonic Wars in 1815, the introduction of new technology to replace agricultural workers in particular, and a series of bad harvests, meant that by the early 1830s the established sy ...
