Many More Projections
Version 11 greatly extends the list of supported cartographic projections.
There are currently 151 projections with a spherical model, which is almost four times the number present in the previous version of the Wolfram Language.

They can be classified according to several criteria. Each projection belongs to several classes. For example, the Mercator projection is a cylindrical projection with the additional property of being conformal.

They can be separated into different types as follows. The "PseudoCylindrical" type is the most common.
