Web Mercator projection

Web Mercator, Pseudo-Mercator, or Google Web Mercator is a variant of the Mercatormap projection used for coordinates in WGS 84 Web Mercator or WGS 84 / Pseudo-Mercator and visualisation. It became the de facto standard for Web mapping applications after Google Maps adopted it in 2005. It is used by virtually all major online map providers, including Google Maps, CARTO, Mapbox, Bing Maps, OpenStreetMap, Mapquest, Esri, and many others. The EPSG identifier for the CRS is EPSG:3857, although others have been used historically.
