@Immutable
public class MillerCylindrical
extends MapProjection

The provider for "Miller" projection. This is a Mercator1SP projection with the following modifications:

1. The parallels of latitude 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 Geotk implementation supports also the ellipsoidal formulas. If spherical formulas are desired, then the parameters shall contains semi-major and semi-minor axis lengths of equal length.

The math transform implementations instantiated by this provider may be any of the following classes:

• Mercator
