Function createSpherical

createSpherical(reference): ConstructiveGeometry
Creates an instance of ConstructiveGeometry that performs operations using spherical approximations of the ellipsoid associated with the given reference. The results of the calculations are less accurate than the ellipsoidal variant, but can be computed faster.
Parameters
- reference: CoordinateReference
  The reference for which a ConstructiveGeometry instance must be created.
Returns ConstructiveGeometry
An instance of ConstructiveGeometry that performs operations using a spherical topology.
