Sinusoidal projection

The sinusoidal projection is one of the oldest known projections, is equal-area, and has been used since the mid-16th century. It has also been called the “Equal-area Mercator” projection. The central meridian is a straight line; all other meridians are sinusoidal curves. Parallels are all equally spaced straight lines, with scale being true along all parallels (and central meridian).

i[lon0/]scale or I[lon0/]width

• i or I: Sets the projection type.

• lon0: Sets the central meridian [Optional].

• scale or width: Sets the map size.
