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.
-
+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.
