TOID
A TOID ( TOpographic IDentifier, pronounced ''toyed'') is a unique reference identifier assigned by the Ordnance Survey to identify every topographical feature in Great Britain. Topographical identifier A TOID consists of two parts: a prefix ‘osgb’, and a unique identifier that is 13-16 digits long. For example, the TOID for the Tower of London is osgb1000006032892. In GML 2, a TOID is encoded as a gml:fid (Feature Identifier); in GML 3 as a gml:id. Around 440 million man-made and natural features have been thus identified: buildings, roads, fields, phone boxes, pillar box A pillar box is a type of free-standing post box. They are found in the United Kingdom and British overseas territories, and, less commonly, in many members of the Commonwealth of Nations such as Cyprus, India, Gibraltar, Hong Kong, Malta, New Z ...es, landmarks and many other types. The identification system is designed to be used in Geographic information system, GIS, digital cartography and in any ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ordnance Survey
Ordnance Survey (OS) is the national mapping agency for Great Britain. The agency's name indicates its original military purpose (see 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 Ordnance Survey has operated as Ordnance Survey Ltd, a government-owned company, 100% in public ownership. The Ordnance Survey Board remains accountable to the Secretary of State for Business, Energy and Industrial Strategy. It was also a member of the Public Data Group. Paper maps for walkers 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 " large-scale" (in other words, more detaile ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OS MasterMap
The OS MasterMap is the premier digital product of the Ordnance Survey. It was launched in November 2001. It is a database that records every fixed feature of Great Britain larger than a few meters in one continuous digital map. Every feature is given a unique TOID (TOpographical IDentifier), a simple identifier that includes no semantic information. Typically each TOID is associated with a polygon that represents the area on the ground that the feature covers, in National Grid coordinates. OS MasterMap is offered in themed "layers", for example a road layer and a building layer, each linked to a number of TOIDs. Pricing of licenses for OS MasterMap data depends on: the total area requested, the layers licensed, the number of TOIDs in the layers, the period in years of the data usage. OS MasterMap can be used to generate maps for a vast array of purposes. Although the scale on a digital map is much more flexible than a paper map, one can print out maps from OS ...

Unique Property Reference Number
The Unique Property Reference Number (UPRN) is a unique alphanumeric identifier (a geocode) for every spatial address in Great Britain and can be found in Ordnance Survey's AddressBase products. A UPRN provides a comprehensive, complete, consistent identifier throughout a property’s life cycle from planning permission through to demolition. For example, the UPRN for 10 Downing Street is 100023336956, and that for Bristol Central Library is 000000199356. The UPRN contains no attribution or information (for example coordinate position) about the property. UPRNs and USRNs ( Unique Street Reference Numbers) are managed by GeoPlace, a joint venture between the Local Government Association and Ordnance Survey to create a definitive national databases of addresses and streets, now available under an Open Government Licence (OGL). The Government Digital Service has mandated the UPRN and USRN as "the public sector standard for referencing and sharing property and street information". ...

Topography
Topography is the study of the forms and features of land surfaces. The topography of an area may refer to the land forms and features themselves, or a description or depiction in maps. Topography is a field of geoscience and planetary science and is concerned with local detail in general, including not only relief, but also natural, artificial, and cultural features such as roads, land boundaries, and buildings. In the United States, topography often means specifically ''relief'', even though the USGS topographic maps record not just elevation contours, but also roads, populated places, structures, land boundaries, and so on. Topography in a narrow sense involves the recording of relief or terrain, the three-dimensional quality of the surface, and the identification of specific landforms; this is also known as geomorphometry. In modern usage, this involves generation of elevation data in digital form (DEM). It is often considered to include the graphic representat ...

Cartography
Cartography (; from grc, χάρτης , "papyrus, sheet of paper, map"; and , "write") is the study and practice of making and using maps. Combining science, aesthetics and technique, cartography builds on the premise that reality (or an imagined reality) can be modeled in ways that communicate spatial information effectively. The fundamental objectives of traditional cartography are to: * Set the map's agenda and select traits of the object to be mapped. This is the concern of map editing. Traits may be physical, such as roads or land masses, or may be abstract, such as toponyms or political boundaries. * Represent the terrain of the mapped object on flat media. This is the concern of map projections. * Eliminate characteristics of the mapped object that are not relevant to the map's purpose. This is the concern of generalization. * Reduce the complexity of the characteristics that will be mapped. This is also the concern of generalization. * Orchestrate the elements of t ...

Geographic Object Identifiers
Geography (from Greek: , ''geographia''. Combination of Greek words ‘Geo’ (The Earth) and ‘Graphien’ (to describe), literally "earth description") is a field of science devoted to the study of the lands, features, inhabitants, and phenomena of Earth. The first recorded use of the word γεωγραφία was as a title of a book by Greek scholar Eratosthenes (276–194 BC). Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. One such concept, the first law of geography, proposed by Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things." Geography has been called "the world discipline" and "the bridge between the human and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unique Street Reference Number
The Unique Street Reference Number (USRN) is an eight-digit unique identifier (a geocode) for every street across Great Britain. The USRNs for England and Wales exists within the National Street Gazetteer (NSG), the authoritative source of information about streets in England and Wales and is a compilation of data from 173 highway authorities' Local Street Gazetteers. The NSG is managed by GeoPlace as a joint venture between the Local Government Association and Ordnance Survey to create definitive national databases of addresses and streets. USRNs in Scotland are managed by the Improvement Service, and in Northern Ireland by the Department for Infrastructure. The USRN is available from the NSG and included in Ordnance Survey's OS MasterMap Highways Network product. USRNs can also be found on the site Find My Street created by GeoPlace. From 1 July 2020, the Government requires USRNs and Unique Property Reference Numbers (UPRNs) to be available under an Open Government Lic ...

Registered Trademark
The registered trademark symbol, , is a typographic symbol that provides notice that the preceding word or symbol is a trademark or service mark that has been registered with a national trademark office. A trademark is a symbol, word, or words legally registered or established by use as representing a company, product or service.For example, Unregistered trademarks can instead be marked with the trademark symbol, , while unregistered service marks are marked with the service mark symbol, . The proper manner to display these symbols is immediately following the mark; the symbol is commonly in superscript style, but that is not legally required. In many jurisdictions, only registered trademarks confer easily defended legal rights. In the US, the registered trademark symbol was originally introduced in the Trademark Act of 1946. Because the symbol is not commonly available on typewriters (or ASCII), it was common to approximate it with the characters (or ). An example of a ...

Spatial Database
A spatial database is a general-purpose database (usually a relational database) that has been enhanced to include spatial data that represents objects defined in a geometric space, along with tools for querying and analyzing such data. Most spatial databases allow the representation of simple geometric objects such as points, lines and polygons. Some spatial databases handle more complex structures such as 3D objects, topological coverages, linear networks, and triangulated irregular networks (TINs). While typical databases have developed to manage various numeric and character types of data, such databases require additional functionality to process spatial data types efficiently, and developers have often added ''geometry'' or ''feature'' data types. The Open Geospatial Consortium (OGC) developed the Simple Features specification (first released in 1997) and sets standards for adding spatial functionality to database systems. The '' SQL/MM Spatial'' ISO/IEC standard is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southampton Central Railway Station
Southampton Central railway station is a main line station serving the city of Southampton in Hampshire, southern England. It is on the South West Main Line and also serves the Wessex Main Line and the West Coastway Line. The station is approached from the London direction by passing through Southampton Tunnel and is measured from .Railways in the United Kingdom historically are measured in miles and chains. There are 80 chains to one mile. The station is managed by South Western Railway who operate the majority of services, including frequent trains to London Waterloo, Bournemouth and Portsmouth Harbour. Other operators are CrossCountry (providing services to Oxford, Birmingham New Street, Manchester Piccadilly and Newcastle), Great Western Railway (to Bristol Temple Meads and Cardiff Central) and Southern, which links Southampton to London Victoria, East Croydon, Gatwick Airport and Brighton.

Wikis
A wiki ( ) is an online hypertext publication collaboratively edited and managed by its own audience, using a web browser. A typical wiki contains multiple pages for the subjects or scope of the project, and could be either open to the public or limited to use within an organization for maintaining its internal knowledge base. Wikis are enabled by wiki software, otherwise known as wiki engines. A wiki engine, being a form of a content management system, differs from other web-based systems such as blog software, in that the content is created without any defined owner or leader, and wikis have little inherent structure, allowing structure to emerge according to the needs of the users. Wiki engines usually allow content to be written using a simplified markup language and sometimes edited with the help of a rich-text editor. There are dozens of different wiki engines in use, both standalone and part of other software, such as bug tracking systems. Some wiki engines are ope ...

Geographic Information System
A geographic information system (GIS) is a type of database containing geographic data (that is, descriptions of phenomena for which location is relevant), combined with software tools for managing, analyzing, and visualizing those data. In a broader sense, one may consider such a system to also include human users and support staff, procedures and workflows, body of knowledge of relevant concepts and methods, and institutional organizations. The uncounted plural, ''geographic information systems'', also abbreviated GIS, is the most common term for the industry and profession concerned with these systems. It is roughly synonymous with geoinformatics and part of the broader geospatial field, which also includes GPS, remote sensing, etc. Geographic information science, the academic discipline that studies these systems and their underlying geographic principles, may also be abbreviated as GIS, but the unambiguous GIScience is more common. GIScience is often considered a sub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
