forward()

auto projection::albers_equal_area::sphere::forward	(	const auto	lon,
		const auto	lat
	)

Projects geographic coordinates (longitude, latitude) onto a planar surface using the Albers Equal-Area Conic projection for a spherical Earth model.

This simplified version assumes a spherical Earth with radius R and is suitable for regional mapping where area preservation is required but ellipsoidal precision is not necessary.

inverse()

auto projection::albers_equal_area::sphere::inverse	(	const auto	x,
		const auto	y
	)

Inverts the spherical Albers Equal-Area Conic projection and returns the geographic coordinates (longitude, latitude in degrees) corresponding to the given planar coordinates (x, y in meters).

This implementation assumes a spherical Earth model and uses the analytical inverse of the projection equations without iteration.
