GB1900
The GB1900 project was a crowd-sourced initiative to create a gazetteer, released under an open licence, by transcribing and geolocating all the place names on the second edition ''County Series'' of six inch to one mile (i.e. 1:10,560) maps of Great Britain, published by Ordnance Survey between 1888 and 1914, and thus out of copyright. Almost 1,200 volunteers contributed. Subsequent research found that they were "motivated by personal interest in the maps, in places that held meaning for them, and in how places had changed." The project began as Cymru1900 in October 2013 under the auspices of the National Library of Wales, the University of Wales Centre for Advanced Welsh and Celtic StudiesPeople's Collection Walesand the Royal Commission on the Ancient and Historical Monuments of Wales, before being relaunched nationally as GB1900 in September 2016 using maps scanned by the National Library of Scotland. The software was updated and hosted by the University of Portsmouth. Transcri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ordnance Survey
The Ordnance Survey (OS) is the national mapping agency for Great Britain. The agency's name indicates its original military purpose (see Artillery, 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, a state-owned enterprise, 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 is usually classified as either "Scale (map), lar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WGS84
The World Geodetic System (WGS) is a standard used in cartography, geodesy, and satellite navigation including GPS. The current version, WGS 84, defines an Earth-centered, Earth-fixed coordinate system and a geodetic datum, and also describes the associated Earth Gravitational Model (EGM) and World Magnetic Model (WMM). The standard is published and maintained by the United States National Geospatial-Intelligence Agency. History Efforts to supplement the various national surveying systems began in the 19th century with F.R. Helmert's book (''Mathematical and Physical Theories of Physical Geodesy''). Austria and Germany founded the (Central Bureau of International Geodesy), and a series of global ellipsoids of the Earth were derived (e.g., Helmert 1906, Hayford 1910 and 1924). A unified geodetic system for the whole world became essential in the 1950s for several reasons: * International space science and the beginning of astronautics. * The lack of inter-continental ...

Crowdsourcing
Crowdsourcing involves a large group of dispersed participants contributing or producing goods or services—including ideas, votes, micro-tasks, and finances—for payment or as volunteers. Contemporary crowdsourcing often involves digital platforms to attract and divide work between participants to achieve a cumulative result. Crowdsourcing is not limited to online activity, however, and there are various historical examples of crowdsourcing. The word crowdsourcing is a portmanteau of "crowd" and "outsourcing". In contrast to outsourcing, crowdsourcing usually involves less specific and more public groups of participants. Advantages of using crowdsourcing include lowered costs, improved speed, improved quality, increased flexibility, and/or increased scalability of the work, as well as promoting diversity. Crowdsourcing methods include competitions, virtual labor markets, open online collaboration and data donation. Some forms of crowdsourcing, such as in "idea competiti ...

Gazetteers
A gazetteer is a geographical dictionary or directory used in conjunction with a map or atlas.Aurousseau, 61. It typically contains information concerning the geographical makeup, social statistics and physical features of a country, region, or continent. Content of a gazetteer can include a subject's location, dimensions of peaks and waterways, population, gross domestic product and literacy rate. This information is generally divided into topics with entries listed in alphabetical order. Ancient Greek gazetteers are known to have existed since the Hellenistic era. The first known Chinese gazetteer was released by the first century, and with the age of print media in China by the ninth century, the Chinese gentry became invested in producing gazetteers for their local areas as a source of information as well as local pride. The geographer Stephanus of Byzantium wrote a geographical dictionary (which currently has missing parts) in the sixth century which influenced later E ...

Wikidata
Wikidata is a collaboratively edited multilingual knowledge graph hosted by the Wikimedia Foundation. It is a common source of open data that Wikimedia projects such as Wikipedia, and anyone else, are able to use under the CC0 public domain license. Wikidata is a wiki powered by the software MediaWiki, including its extension for semi-structured data, the Wikibase. As of early 2025, Wikidata had 1.65 billion item statements ( semantic triples). Concept Wikidata is a document-oriented database, focusing on ''items'', which represent any kind of topic, concept, or object. Each item is allocated a unique persistent identifier called its ''QID'', a positive integer prefixed with the upper-case letter "Q". This makes it possible to provide translations of the basic information describing the topic each item covers without favouring any particular language. Some examples of items and their QIDs are , , , , and . Item ''labels'' do not need to be unique. For example, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vision Of Britain
The Great Britain Historical GIS (or GBHGIS) is a spatially enabled database that documents and visualises the changing human geography of the British Isles, although is primarily focussed on the subdivisions of the United Kingdom mainly over the 200 years since the first census in 1801. The project is currently based at the University of Portsmouth, and is the provider of the website ''A Vision of Britain through Time''. NB: A "GIS" is a geographic information system, which combines map information with statistical data to produce a visual picture of the iterations or popularity of a particular set of statistics, overlaid on a map of the geographic area of interest. Original GB Historical GIS (1994–99) The first version of the GB Historical GIS was developed at Queen Mary, University of London between 1994 and 1999, although it was originally conceived simply as a mapping extension to the existing Labour Markets Database (LMDB). The system included digital boundaries for re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hexadecimal
Hexadecimal (also known as base-16 or simply hex) is a Numeral system#Positional systems in detail, positional numeral system that represents numbers using a radix (base) of sixteen. Unlike the decimal system representing numbers using ten symbols, hexadecimal uses sixteen distinct symbols, most often the symbols "0"–"9" to represent values 0 to 9 and "A"–"F" to represent values from ten to fifteen. Software developers and system designers widely use hexadecimal numbers because they provide a convenient representation of binary code, binary-coded values. Each hexadecimal digit represents four bits (binary digits), also known as a nibble (or nybble). For example, an 8-bit byte is two hexadecimal digits and its value can be written as to in hexadecimal. In mathematics, a subscript is typically used to specify the base. For example, the decimal value would be expressed in hexadecimal as . In programming, several notations denote hexadecimal numbers, usually involving a prefi ...

Ordnance Survey National Grid
The Ordnance Survey National Grid reference system (OSGB), also known as British National Grid (BNG), is a system of geographic grid references, distinct from latitude and longitude, whereby any location in Great Britain can be described in terms of its distance from the origin (0, 0), which lies to the west of the Isles of Scilly. The Ordnance Survey (OS) devised the national grid reference system, and it is heavily used in its survey data, and in maps based on those surveys, whether published by the Ordnance Survey or by commercial map producers. Grid references are also commonly quoted in other publications and data sources, such as guide books and government planning documents. A number of different systems exist that can provide grid references for locations within the British Isles: this article describes the system created solely for Great Britain and its outlying islands (including the Isle of Man). The Irish grid reference system is a similar system created by the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wikimedia UK
Wikimedia UK (WMUK), also known as Wikimedia United Kingdom, is a Charitable organization, registered charity established to support volunteers in the United Kingdom who work on Wikimedia projects such as Wikipedia. As such, it is a Wikimedia chapter approved by the Wikimedia Foundation (WMF), which owns and hosts those projects. Wikimedia UK started out as Wiki Educational Resources Limited (WER), but due to financial difficulties and other problems the organisation dissolved, and was replaced by Wiki UK Limited.
