Sinusoidal (Sanson-Flamsteed)¶
MacBryde and Thomas developed generalized formulas for several of the pseudocylindricals with sinusoidal meridians:
\[x = C\lambda(m+cos\theta) / ( m + 1)\]
\[y = C\theta\]
\[C = \sqrt { (m + 1 ) / n }\]
Parameters¶
Note
All parameters are optional for the Sinusoidal projection.
-
+lon_0
=<value>
¶ Longitude of projection center.
Defaults to 0.0.
-
+R
=<value>
¶ Radius of the sphere given in meters. If used in conjunction with
+ellps
+R
takes precedence.
-
+x_0
=<value>
¶ False easting.
Defaults to 0.0.
-
+y_0
=<value>
¶ False northing.
Defaults to 0.0.
