and editor. In 2004, OpenStreetMap was created by Steve Coast in response to the Ordnance Survey, the United Kingdom's national mapping agency, failing to release its data to the public and under free licences. Initially, maps were created only via GPS traces, but it was quickly populated by importing public domain geographical data such as the U.S. TIGER and tracing permitted aerial photography. OpenStreetMap's adoption was accelerated by Google Maps's introduction of pricing in 2012 and the development of supporting software and applications. The database is hosted by the

History

Steve Coast founded the project in 2004 while at university in Britain, initially focusing on mapping the United Kingdom. In the UK and elsewhere, government-run and tax-funded projects like the Ordnance Survey created massive datasets but failed to freely and widely distribute them. The first contribution was made in the city of London in 2005. In April 2006, the
OpenStreetMap Foundation The OpenStreetMap Foundation (abbreviated OSMF) is a non-profit foundation whose aim is to support and enable the development of freely-reusable geospatial data. It is closely connected with the OpenStreetMap project, although its constitution does ...
was established to encourage the growth, development and distribution of free geospatial data and provide geospatial data for anybody to use and share. In December 2006, Yahoo! confirmed that OpenStreetMap could use its aerial photography as a backdrop for map production. In April 2007, Automotive Navigation Data (AND) donated a complete road data set for the Netherlands and trunk road data for India and China to the project and by July 2007, when the first OpenStreetMap international The State of the Map conference was held, there were 9,000 registered users. Sponsors of the event included Google, Yahoo! and Multimap. In October 2007, OpenStreetMap completed the import of a US Census TIGER road dataset. In December 2007, Oxford University became the first major organisation to use OpenStreetMap data on their main website. Ways to import and export data have continued to grow – by 2008, the project developed tools to export OpenStreetMap data to power portable GPS units, replacing their existing proprietary and out-of-date maps. In March, two founders of CloudMade, a commercial company that uses OpenStreetMap data, announced that they had received venture capital funding of €2.4million. In November 2010, Bing changed their licence to allow use of their satellite imagery for making maps. In 2012, the launch of pricing for Google Maps led several prominent websites to switch from their service to OpenStreetMap and other competitors. Chief among these were Foursquare and Craigslist, which adopted OpenStreetMap, and Apple, which ended a contract with Google and launched a self-built mapping platform using TomTom and OpenStreetMap data. In 2017, DigitalGlobe started providing satellite imagery to aid OpenStreetMap contributions. In June 2021, OpenStreetMap Foundation announced plans to move from the United Kingdom to a country in the European Union, citing Brexit as the inciting factor. According to the organisation, there are several reasons for the move, including "the failure of the UK and EU to agree on mutual recognition of database rights", the rising difficulties in "banking, finance and using PayPal in the UK" and the loss of

Data structure

OpenStreetMap uses a topological
data structure In computer science, a data structure is a data organization, management, and storage format that is usually chosen for efficient access to data. More precisely, a data structure is a collection of data values, the relationships among them, a ...
, with four core elements (also known as ''data primitives''): * ''Nodes'' are points with a geographic position, stored as coordinates (pairs of a latitude and a longitude) according to WGS 84. Outside of their usage in ''ways'', they are used to represent map features without a size, such as
points of interest A point of interest (POI) is a specific point location that someone may find useful or interesting. An example is a point on the Earth representing the location of the Eiffel Tower, or a point on Mars representing the location of its highest m ...
or mountain peaks. * ''Ways'' are ordered lists of ''nodes'', representing a polyline, or possibly a polygon if they form a closed loop. They are used both for representing linear features such as streets and rivers, and areas, like forests, parks, parking areas and lakes. * ''Relations'' are ordered lists of ''nodes'', ''ways'' and ''relations'' (together called "members"), where each member can optionally have a "role" (a string). Relations are used for representing the relationship of existing ''nodes'' and ''ways''. Examples include turn restrictions on roads, routes that span several existing ''ways'' (for instance, a long-distance motorway), and areas with holes. * '' Tags'' are key-value pairs (both arbitrary strings). They are used to store
metadata Metadata is "data that provides information about other data", but not the content of the data, such as the text of a message or the image itself. There are many distinct types of metadata, including: * Descriptive metadata – the descriptive ...
about the map objects (such as their type, their name and their physical properties). Tags are not freestanding, but are always attached to an object: to a ''node'', a ''way'' or a ''relation''. A recommended ontology of map features (the meaning of ''tags'') is maintained on a wiki. New tagging schemes can always be proposed by a popular vote of a written proposal in OpenStreetMap wiki, however, there is no requirement to follow this process. There are over 89 million different kinds of tags in use as of June 2017. The OpenStreetMap data primitives are stored and processed in different formats. The main copy of the OpenStreetMap data is stored in OpenStreetMap's main database. The main database is a
PostgreSQL PostgreSQL (, ), also known as Postgres, is a free and open-source relational database management system (RDBMS) emphasizing extensibility and SQL compliance. It was originally named POSTGRES, referring to its origins as a successor to the In ...
database, which has one table for each data primitive, with individual objects stored as rows. All edits happen in this database, and all other formats are created from it. For data transfer, several database dumps are created, which are available for download. The complete dump is called planet.osm. These dumps exist in two formats, one using XML and one using the Protocol Buffer Binary Format (PBF).


Data collection

Map data is collected from scratch by volunteers performing systematic ground surveys using tools such as a handheld GPS unit, a

including JOSM and Merkaator. Mapathon competition events are also held by OpenStreetMap team and by non-profit organisations and local governments to map a particular area. The availability of aerial photography and other data from commercial and government sources has added important sources of data for manual editing and automated imports. Special processes are in place to handle automated imports and avoid legal and technical problems. OpenStreetMap data has been favourably compared with proprietary datasources, although data quality varied across the world.

, motorcycle, or boat. Map data was typically recorded on a GPS unit. In late 2006 Yahoo! made their aerial imagery available for tracing to OpenStreetMap contributors, which simplified mapping of readily visible and identifiable features. The project still makes use of GPS traces from volunteers which are used to delineate the more difficult to identify and classify features such as

, as well as providing ground-truth for aerial imagery alignment. Once the data has been collected, it is entered into the database by uploading it onto the project's website together with appropriate attribute data. As collecting and uploading data may be separated from editing objects, contribution to the project is possible without using a GPS unit. Some committed contributors adopt the task of mapping whole towns and cities, or organising mapping parties to gather the support of others to complete a map area. A large number of less active users contribute corrections and small additions to the map.


Street-level image data

In addition to several different sets of satellite image backgrounds available to OpenStreetMap editors, data from several street-level image platforms are available as map data photo overlays: Bing Streetside 360° image tracks, and the open and crowdsourced Mapillary and

Government data

Some government agencies have released official data on appropriate licences. This includes the United States, where works of the

. In the UK, some Ordnance Survey OpenData is imported. In Canada Natural Resources Canada's CanVec vector data and GeoBase provide landcover and streets. Out-of-copyright maps can be good sources of information about features that do not change frequently. Copyright periods vary, but in the UK Crown copyright expires after 50 years and hence Ordnance Survey maps until the 1960s can legally be used. A complete set of UK 1 inch/mile maps from the late 1940s and early 1950s has been collected, scanned, and is available online as a resource for contributors.


Contributors

The project has a geographically diverse user-base, due to emphasis of local knowledge and "on-the-ground" situation in the process of data collection. Many early contributors were cyclists who survey with and for bicyclists, charting cycleroutes and navigable trails. Others are

professionals who contribute data with an extension for ArcGIS. Contributors are predominately men, with only 3–5% being women. By August 2008, shortly after the second The State of the Map conference was held, there were over 50,000 registered contributors; by March 2009, there were 100,000 and by the end of 2009 the figure was nearly 200,000. In April 2012, OpenStreetMap cleared 600,000 registered contributors. On 6 January 2013, OpenStreetMap reached one million registered users. Around 30% of users have contributed at least one point to the OpenStreetMap database. Since 2007, the OpenStreetMap community has held an annual, international conference called ''State of the Map''. There are also various national, regional and continental SotM conferences, such as SotM U.S., SotM Baltics, SotM Asia & SotM Africa.


Commercial contributors

Some OpenStreetMap data is supplied by companies that choose to freely license either actual street data or satellite imagery sources from which OpenStreetMap contributors can trace roads and features. Notably, Automotive Navigation Data provided a complete road data set for Netherlands and details of trunk roads in China and India. In December 2006, Yahoo! confirmed that OpenStreetMap was able to make use of their vertical aerial imagery and this photography was available within the editing software as an overlay. Contributors could create their vector based maps as a derived work, released with a

and open licence, until the shutdown of the Yahoo! Maps API on 13 September 2011. In November 2010, Microsoft announced that the OpenStreetMap community could use Bing vertical aerial imagery as a backdrop in its editors. For a period from 2009 to 2011, NearMap Pty Ltd made their high-resolution PhotoMaps (of major Australian cities, plus some rural Australian areas) available for deriving OpenStreetMap data under a CC BY-SA licence. In June 2018, the Microsoft Bing team announced a major contribution of 125 million U.S. building footprints to the project – four times the number contributed by users and government data imports.

(ODbL) published by Open Data Commons (ODC) in order to more specifically define its bearing on data rather than representation. As part of this relicensing process, some of the map data was removed from the public distribution. This included all data contributed by members that did not agree to the new licensing terms, as well as all subsequent edits to those affected objects. It also included any data contributed based on input data that was not compatible with the new terms. Estimates suggested that over 97% of data would be retained globally, but certain regions would be affected more than others, such as in Australia where 24 to 84% of objects would be retained, depending on the type of object. Ultimately, more than 99% of the data was retained, with Australia and Poland being the countries most severely affected by the change. All data added to the project needs to have a licence compatible with the Open Database Licence. This can include out-of-copyright information, public domain or other licences. Contributors agree to a set of terms which require compatibility with the current licence. This may involve examining licences for government data to establish whether it is compatible. Software used in the production and presentation of OpenStreetMap data is available from many different projects and each may have its own licensing. The application what users access to edit maps and view changelogs, is powered by Ruby on Rails. The application also uses
