Sinusoidal (Sanson-Flamsteed)

Sinusoidal (Sanson-Flamsteed)

proj-string: +proj=sinu

MacBryde and Thomas developed generalized formulas for several of the pseudocylindricals with sinusoidal meridians:

\[x = C\lambda(m+cos\theta) / ( m + 1)\]
\[y = C\theta\]
\[C = \sqrt { (m + 1 ) / n }\]



All parameters are optional for the Sinusoidal projection.


Longitude of projection center.

Defaults to 0.0.


Radius of the sphere given in meters. If used in conjunction with +ellps +R takes precedence.


False easting.

Defaults to 0.0.


False northing.

Defaults to 0.0.
