Sphere wgs84
Web Mercator is a slight variant of the Mercator projection, one used primarily in Web-based mapping programs. It uses the same formulas as the standard Mercator as used for small-scale maps. However, the Web Mercator uses the spherical formulas at all scales whereas large-scale Mercator maps normally use the ellipsoidal form of the projection. The discrepancy is imperceptible at the global scale but causes maps of local areas to deviate slightly from true elli… WebThe projection used for all tiled base map services in The National Map is the World Geodetic System 1984 (WGS 84) Web Mercator (Auxiliary Sphere) so that base map services can be used in combination with other common viewers.

WebAug 15, 2014 · You have a weird case, in that WGS 1984 Major Auxiliary Sphere isn't a "real" geodetic GCS (datum). Coordinates are the same as in WGS 1984, but are treated as if they're on a sphere with radius 6378137.0 m. If there were two or more geodetic datums involved, you would need to pick transformations.
