Contributors collect data from surveys, trace from aerial imagery and also import from other freely licensed geodata sources. OpenStreetMap is freely licensed under the Open Database License and as a result commonly used to make electronic maps, inform turn-by-turn navigation, assist in humanitarian aid and data visualisation. OpenStreetMap uses its own topology to store geographical features which can then be exported into other GIS file formats. The OpenStreetMap website itself is an online map, geodata search engine and editor.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 under free licences in 2004. 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 by tracing permitted aerial photography or satellite imagery. 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 OpenStreetMap Foundation, a non-profit organisation registered in England and Wales and is funded mostly via donations. Meta (formerly Facebook) launched its distribution called Daylight, based on OSM in 2020. The Linux Foundation’s Overture Maps Foundation released their first open map data based on OSM and other sources in July 2023.

History

(File:Steve Coast - OSM im Rheinland (0604).jpg|thumb|The founder of OpenStreetMap, Steve Coast, in 2009)Steve Coast founded the project in 2004 while at a university in Britain, initially focusing on mapping the United Kingdom.{{Sfn|Foody|2017|p=38}} In the UK and elsewhere, government-run and tax-funded projects like the Ordnance Survey created massive datasets but declined to freely and widely distribute them. The first contribution was made in London in 2005.WEB, Coast, Steve, Changeset #1 on OpenStreetMap,www.openstreetmap.org/changeset/1, OpenStreetMap, 9 April 2005, 19 September 2018, 19 September 2018,web.archive.org/web/20180919132731/https://www.openstreetmap.org/changeset/1, live, {{Primary source inline|date=May 2023|reason=This is a discussion around Changeset:1 in OSM - valid, but primary}} In April 2006, the OpenStreetMap Foundation was established to encourage the growth, development and distribution of free geospatial data and provide geospatial data for anybody to use and share.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. By July 2007, when the first “The State of the Map“(SotM) conferenceWEB, State of the Map,stateofthemap.org/, 13 August 2022, stateofthemap.org, 7 April 2017,web.archive.org/web/20170407051823/https://stateofthemap.org/, live, was held, there were 9,000 registered users. 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 â€“ 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 2008, two founders of CloudMade, a commercial company that uses OpenStreetMap data, announced that they had received venture capital funding of â‚¬2.4{{nbsp}}million.PRESS RELEASE, 17 March 2008, Open-source mapping company CloudMade raises â‚¬2.4 million in Series A financing round from Sunstone Capital,cloudmade.com/2008/03/20080317%20cloudmade%20press%20release.pdf, dead,cloudmade.com/2008/03/20080317%20cloudmade%20press%20release.pdf," title="web.archive.org/web/20120113201923if_cloudmade.com/2008/03/20080317%20cloudmade%20press%20release.pdf,">web.archive.org/web/20120113201923if_cloudmade.com/2008/03/20080317%20cloudmade%20press%20release.pdf, 13 January 2012, 16 September 2022, Yahoo!

OSM Data

Data structure

(File:OpenStreetMap data primitives in iD.png|alt=see caption|thumb|Illustration of OpenStreetMap data primitives (nodes, ways and relations))OpenStreetMap uses a topological data structure, 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 or mountain peaks.{{Sfn|Foody|2017|p=39}}
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.{{Sfn|Foody|2017|p=39}}

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.{{Sfn|Foody|2017|p=39}}
Tags are key-value pairs (both arbitrary strings). They are used to store metadata 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.{{Sfn|Foody|2017|p=39}} A recommended ontology of map features (the meaning of tags) is (openstreetmap:Map features|maintained on a wiki). New tagging schemes can always be proposed by a (OpenStreetmap:Proposal process|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.JOURNAL, Mocnik, Franz-Benjamin, Zipf, Alexander, Raifer, Martin, 18 September 2017, The OpenStreetMap folksonomy and its evolution, Geo-spatial Information Science, 20, 3, 219â€“230, 10.1080/10095020.2017.1368193, 2017GSIS...20..219M, free,

The OpenStreetMap data primitives are stored and processed in different formats. OpenStreetMap server uses PostgreSQL database, with one table for each data primitive, with individual objects stored as rows.WEB, OpenStreetMap Wiki: Database,wiki.openstreetmap.org/wiki/Database, live,wiki.openstreetmap.org/wiki/Database," title="web.archive.org/web/20150210113302wiki.openstreetmap.org/wiki/Database,">web.archive.org/web/20150210113302wiki.openstreetmap.org/wiki/Database, 10 February 2015, 10 February 2015, OpenStreetMap, WEB, Databases and data access APIs,wiki.openstreetmap.org/wiki/Databases_and_data_access_APIs, live,web.archive.org/web/20171018072509/https://wiki.openstreetmap.org/wiki/Databases_and_data_access_APIs, 18 October 2017, 18 October 2017, From this, several database dumps are created, which are available for download.

Map making

Data sources

File:Adding data to OSM after mapping Brighton Pier.jpg|thumb|Editing with JOSM JOSMMap data is collected by ground survey, personal knowledge, digitizing from imagery, and government data. Ground survey data is collected by volunteers traditionally using tools such as a handheld GPS unit, a notebook, digital camera and voice recorder. Software applications on smartphones (mobile devices) have made it easy for anybody to survey. The data is then entered into the OpenStreetMap database using a number of software tools including JOSM and Merkaator. Mapathon competition events are also held by local OpenStreetMap teams 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.

Surveys and personal knowledge

File:Motion X GPS and OSM.jpg|thumb|Surveying routes with a satellite navigation device satellite navigation deviceGround surveys are performed by a mapper, on foot, bicycle, or in a car, motorcycle, or boat. Map data was typically recorded on a GPS unit or on a smart phone with mapping app. 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, e.g. by using Paper mapping.Similar to users contributing data using GPS unit, corporations (e.g. Amazon) with large vehicle fleets use telemetry data from the vehicles to contribute data to OpenStreetMap.JOURNAL, Sarkar, Dipto, Anderson, Jennings T., Corporate editors in OpenStreetMap: Investigating co-editing patterns, Transactions in GIS, June 2022, 26, 4, 1879â€“1897, 10.1111/tgis.12910, 2022TrGIS..26.1879S, 247178270, 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.{{citation needed|date=June 2022}}

Satellite/Aerial images

Maxar, Bing, ESRI, and Mapbox are some of the providers of aerial/satellite imagery which are used as a backdrop for map production.

Street-level image data

Data from several street-level image platforms are available as map data photo overlays. Bing Streetside 360Â° image tracks, and the open and crowdsourced Mapillary and KartaView platforms provide generally smartphone and windshield-mounted camera images. Additionally, a Mapillary traffic sign data layer, a product of user-submitted images is also available.JOURNAL, Crowdsourcing Street View Imagery: A Comparison of Mapillary and OpenStreetCam, 26 May 2020, ISPRS International Journal of Geo-Information, 2020IJGI....9..341M, Mahabir, Ron, Schuchard, Ross, Crooks, Andrew, Croitoru, Arie, Stefanidis, Anthony, 9, 6, 341, 10.3390/ijgi9060341, free,

Government data

Some government agencies have released official data on appropriate licences. This includes the United States, where works of the federal government are placed under public domain.In the United States, most roads originate from TIGER from the Census Bureau.WEB,www.e-education.psu.edu/geog855/node/798, 2.2 Exploring TIGER and OSM Data, Penn State College, 15 June 2022, 7 August 2022,web.archive.org/web/20220807183312/https://www.e-education.psu.edu/geog855/node/798, live, > Geographic names were initially sourced from Geographic Names Information System, and some areas contain water features from the National Hydrography Dataset. In the UK, some Ordnance Survey OpenData is imported. In Canada Natural Resources Canada’s CanVec vector data and GeoBase provide landcover and streets.{{citation needed|date=June 2022}}Globally, OpenStreetMap initially used the prototype global shoreline from NOAA. Due to it being oversimplified and crude, it has been mainly replaced by other government sources or manual tracing.{{citation needed|date=June 2022}}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 old Ordnance Survey maps can legally be used.

Non-governmental organisations

{{Anchor|HOT}}Humanitarian OpenStreetMap Team (HOT) is a nonprofit organisation promoting community mapping across the world. It developed the open source HOT Tasking Manager for collaboration, and contributed to mapping efforts after the April 2015 Nepal earthquake, the 2016 Kumamoto earthquakes, and the 2016 Ecuador earthquake. The Missing Maps Project, founded by the American Red Cross, Doctors Without Borders, and other NGOs, uses HOT Tasking Manager. The University of Heidelberg hosts the Disastermappers Project for training university students in mapping for humanitarian purposes. When Ebola broke out in 2014, the volunteers mapped 100,000 buildings and hundreds of miles of roads in Guinea in just five days.{{Sfn|Foody|2017|p=43}}

Software

(File:OSM Components.svg|300px|OSM application architectural components|alt=OSM application architectural components|thumb)OpenStreetMap applications utilize multiple components to provide services. The map data is rendered using pre-generated tiles for various levels of zoom. Editing applications typically support display of imagery, and field mapping data in the form of GPS traces and voice, photo, video annotations to aid in editing map. JOSM, ID, StreetComplete, Rapid, Potlatch are the top 5 editing tools for contributions during 2018â€“2023 according to a study by Heigit.WEB,heigit.org/exploring-osm-editor-statistics-by-combining-data-from-oshdb-and-changeset-db/, Exploring OSM editor statistics by combining data from OSHDB and changeset DB, 1 August 2023, 7 August 2023,
