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
,+R
takes 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.
