@Immutable
public class EquidistantCylindrical
extends MapProjection

The provider for "Equidistant Cylindrical" projection (EPSG:1028, EPSG:1029, EPSG:9842, EPSG:9823).

Note: EPSG defines two codes for this projection, 1029 being the spherical case and 1028 the ellipsoidal case. However the formulas are the same in both cases, with an additional adjustment of Earth radius in the ellipsoidal case. Consequently they are implemented in Geotk by the same class.

Note: EPSG:1028 and 1029 are the current codes, while EPSG:9842 and 9823 are deprecated codes. The new and deprecated definitions differ only by their names. In the Geotk implementation, both current and legacy definitions are known, but the legacy names are marked as deprecated.

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

• Equirectangular
