OpenStreetMap
OpenStreetMap (abbreviated OSM) is a free, Open Database License, open geographic database, map database updated and maintained by a community of volunteers via open collaboration. Contributors collect data from surveying, surveys, trace from Aerial photography, aerial photo imagery or satellite imagery, and import from other freely licensed geodata sources. OpenStreetMap is Free content, freely licensed under the Open Database License and is commonly used to make electronic maps, inform turn-by-turn navigation, and assist in humanitarian aid and Data and information visualization, data visualisation. OpenStreetMap uses its own data model to store geographical features which can then be exported into other GIS file formats. The OpenStreetMap website itself is an Web mapping, 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 pub ...

Initially, maps in OSM were created only via GPS traces, but it was quickly populated by importi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OpenStreetMap Foundation
The OpenStreetMap Foundation (abbreviated OSMF) is a non-profit organisation whose aim is to support and enable the development of freely-reusable geospatial data. Founded in 2006, it is closely connected with the OpenStreetMap project, although its constitution does not prevent it supporting other projects. History The OpenStreetMap Foundation was registered in England and Wales on 22 August 2006 as a company limited by guarantee. In 2007, it held the first State of the Map conference in Manchester. In October 2009, the foundation announced that its members, rather than the OpenStreetMap contributors at large, would vote on changing OpenStreetMap's data license from Creative Commons Attribution-ShareAlike to the Open Database License. In September 2013, the foundation began accepting corporate memberships in an "associate member" (nonvoting) category. The initial corporate members were Geofabrik, Geotab, Naver, NextGIS, and Mapbox. In 2018, GlobalLogic was implicated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steve Coast
Stephen Coast (born 20 December 1980) is a British entrepreneur and the founder of the OpenStreetMap community-based world mapping project and CloudMade, a geography-related company. Early life Coast grew up in Walderslade and London, United Kingdom. Career Coast was an intern at Wolfram Research before studying computing science at University College London (UCL). In July 2004, he founded the OpenStreetMap project (OSM). Coast set up Z.X.V. Ltd. with Nick Black, Tom Carden and Ben Gimpert as a technology consultancy in 2005. In 2008 this became CloudMade after investment by Nikolaj Nyholm and Sunstone Capital (company's website claims it was established in 2007). He resigned from CloudMade in October 2010, although he remained a shareholder. On 23 November 2010, Coast announced that he had accepted a position as Principal Architect at Microsoft's Bing Mobile. On 3 September 2013, Coast wrote on his blog that he had started to work for TeleNav, taking care of OSM devel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tiled Web Map
A tiled web map or tile map (also known as slippy map in OpenStreetMap), is a web map displayed by seamlessly joining dozens of individually requested data files, called "tiles". It is the most popular way to display and navigate maps, replacing other methods such as Web Map Service (WMS) which typically display a single large image, with arrow buttons to navigate to nearby areas. Google Maps was one of the first major mapping sites to use this technique. The first tiled web maps used Raster graphics, raster tiles, before the emergence of vector tiles. There are several advantages to tiled maps. Each time the user pans, most of the tiles are still relevant, and can be kept displayed, while new tiles are fetched. This greatly improves the user experience, compared to fetching a single map image for the whole viewport. It also allows individual tiles to be pre-computed, a task easy to parallelize. Also, displaying rendered images served from a web server is less computationally dem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
