pe_phi_to_mu |
Calculates the rectifying latitude from the geographic latitude
double pe_phi_to_mu (double e2, double phi);
e2 | Eccentricity squared of the spheroid |
phi | Geographic latitude (measured in radians) of the point |
Rectifying latitude is used to map the spheroid to an auxiliary sphere in such a way that correct distances along the meridians are preserved.
