Parameters¶
Required¶
For the Oblique Cylindrical Equal Area projection a pole of rotation is needed. The pole can be defined in two ways: By a point and azimuth or by providing to points that make up the pole.
Point & azimuth¶
- +lonc=<value>¶
Longitude of rotational pole point.
- +alpha=<value>¶
Angle of rotational pole.
Two points¶
- +lon_1=<value>¶
Longitude of first point.
- +lat_1=<value>¶
Latitude of first point.
- +lon_2=<value>¶
Longitude of second point.
- +lat_2=<value>¶
Latitude of second point.
Optional¶
- +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,+Rtakes precedence.See Ellipsoid size parameters for more information.
- +k_0=<value>¶
Scale factor. Determines scale factor used in the projection.
Defaults to 1.0.
- +x_0=<value>¶
False easting.
Defaults to 0.0.
- +y_0=<value>¶
False northing.
Defaults to 0.0.
