Lines 9 to 18 in 9d25a5a

	module Geospatial
	# Wrapper to Rgeo's Point
	Point.class_eval do
	#
	# With RGeo support
	#
	# @return (RGeo::SphericalFactory::Point)
	def to_rgeo
	RGeo::Geographic.spherical_factory.point x, y
	end

Here, and everywhere else, the spherical_factory is being used to convert geometries from geospatial Objects into RGeos objects. However, this may not always be the best choice.

The library geo_json already has a solution, that may serve as a guide:
