proj-string: +proj=oea +m=1 +n=2¶
Described in [Snyder1988].
Parameters¶
Required¶
- +m=<value>¶
- +n=<value>¶
Optional¶
- +theta=<value>¶
- +lon_0=<value>¶
Longitude of projection center.
Defaults to 0.0.
Note
The default convention is to interpret this value as decimal degrees. To specify radians instead, follow the value with the “r” character.
Example: +lon_0=1.5708r
See Projection Units for more information.
- +R=<value>¶
Radius of the sphere, given in meters. If used in conjunction with
+ellps,+Rtakes precedence.See Ellipsoid size parameters for more information.
- +x_0=<value>¶
False easting.
Defaults to 0.0.
- +y_0=<value>¶
False northing.
Defaults to 0.0.
