Ellipsoidal parameters. Some are derivable from others.
flattening :: Ellipsoid -> DoubleSource
The ellipsoidal flattening.
inverseFlattening :: Ellipsoid -> DoubleSource
The inverse of the ellipsoidal flattening.
Arguments
| :: Double | The semi major axis in metres. |
| -> Double | The semi minor axis in metres. |
| -> Double | The ellipsoidal flattening. |
| -> Double | The inverse of the ellipsoidal flattening. |
| -> Ellipsoid |
Construct an ellipsoid with the given parameters.
Arguments
| :: Double | The semi major axis. |
| -> Double | The inverse of the ellipsoidal flattening. |
| -> Ellipsoid |
