Equal-Area Cylindrical – Global Mapper

The Equal-Area Cylindrical projection represents an orthographic projection of a sphere onto a cylinder. Like other regular cylindrical projections, the graticule of the normal Equal-Area Cylindrical projection consists of straight equally spaced vertical meridians perpendicular to straight unequally spaced horizontal parallels. To achieve equality of area, the parallels are spaced from the Equator in proportion to the sine of the latitude. This is the simplest equal-area projection.

The "EqualAreaCylindrical" Projection has the following Parameters:

Parameter Name	Parameter String	Units
Longitude of the Center of the Projection	central_meridian	AngularValue
Latitude of the Origin of the Projection	latitude_of_origin	AngularValue
False Easting	false_easting	LinearValue
False Northing	false_northing	LinearValue

NOTE: Only a spherical form of this projection is used. The semi-major axis of the ellipsoid (sphere) is used for forward and inverse projection from grid to geodetic coordinates within the system wherein this projection is incorporated.
