The Mollweide projection is a pseudocylindrical equal-area projection. The central meridian is a straight line, 90th meridians are circular arcs, and all other meridians are equally spaced elliptical arcs. Parallels are unequally spaced straight lines, parallel to each other. Poles are shown as points. This projection is used only in spherical form. The "Mollweide" projection has the following parameters:
- Spherical radius
- False Northing
- False Easting
- Longitude of natural origin
Only a spherical form of this projection is used. The semi-major axis of the ellipsoid will be used as the radius of the sphere.
