Parameters¶
Note
All parameters are optional for the projection.
- +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.
- +R=<value>¶
Radius of the sphere, given in meters. If used in conjunction with
+ellps
,+R
takes precedence.See Ellipsoid size parameters for more information.
- +x_0=<value>¶
False easting, easting at false origin or easting at projection centre (naming and meaning depend on the projection method). Always in meters.
Defaults to 0.0.
- +y_0=<value>¶
False northing, northing at false origin or northing at projection centre (naming and meaning depend on the projection method). Always in meters.
Defaults to 0.0.
