Web Mercator Projection – One of Cylindrical Projections of an Ellipsoid to a Plane

The Web Mercator projection is a of relatively recent date. There has been lot controversy about its application. Some believe that this not either the sphere or surface ellipsoid. Therefore, in paper, several projections rotational ellipsoid into plane are investigated and it shown one such projections. Namely, although equations identical to for sphere, basic difference choice area definition, i.e., domain projection. Furthermore, we have can also be interpreted as double mapping: mapping an according normals then formulas sphere. conformal projection, but close properties
