public final class MillerCylindrical extends MapProjection
The provider for "Miller Cylindrical" projection. This is a Mercator1SP projection with the following modifications:
  1. The latitude of parallels are scaled by a factor of 0.8 before the projection (actually 2×0.4 where the factor 2 is required for canceling the scaling performed by the classical Mercator formula).
  2. The northing is multiplied by 1.25 after the projection.
Note that the Miller projection is typically used with spherical formulas. However, the Apache SIS implementation supports also the ellipsoidal formulas. If spherical formulas are desired, then the parameters shall contain semi-major and semi-minor axis lengths of equal length.
