pe_chi_to_phi

Calculates the geographic latitude from the conformal latitude

Usage syntax

double pe_chi_to_phi (double e2, double chi);

Parameters
e2 Eccentricity squared of the spheroid
chi Conformal latitude (measured in radians) of the point
Description

This function is the inverse of pe_phi_to_chi; pe_chi_to_phi(e2, pe_phi_to_chi(e2, phi)) is approximately equal to phi.

Returns

Geographic latitude (measured in radians) of the point
