forward()

template<auto Lon0Deg, auto Lat0Deg, auto StdParallel1Deg, auto StdParallel2Deg, auto EarthRadius>

static auto projection::AEA::sphere::forward ( const auto lon, const auto lat )

static

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()

template<auto Lon0Deg, auto Lat0Deg, auto StdParallel1Deg, auto StdParallel2Deg, auto EarthRadius>

static auto projection::AEA::sphere::inverse ( const auto x, const auto y )

static

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.
