Web Mercator projection information


The Web Mercator projection is almost indistinguishable at global scale from a Mercator projection cropped to around 85°N to 85°S
Homepage of OpenStreetMap in 2018. The standard style for OpenStreetMap, like most Web maps, uses the Web Mercator projection

Web Mercator, Google Web Mercator, Spherical Mercator, WGS 84 Web Mercator[1] or WGS 84/Pseudo-Mercator is a variant of the Mercator map projection and is the de facto standard for Web mapping applications. It rose to prominence when Google Maps adopted it in 2005.[2] It is used by virtually all major online map providers, including Google Maps, CARTO, Mapbox,[3] Bing Maps, OpenStreetMap, Mapquest, Esri, and many others.[4] Its official EPSG identifier is EPSG:3857, although others have been used historically.
