pyacs.lib.coordinates.wnorm.wnorm(phi, A=6378137.0, E2=0.006694380022903)[source]

Calculate the geodetic radius of curvature normal to the ellipsoid.

Parameters:

  • phi (float or ndarray) – Geodetic latitude in radians.

  • A (float, optional) – Semi-major axis of the ellipsoid (default WGS84 in m).

  • E2 (float, optional) – First eccentricity squared (default WGS84).

Returns:

Radius of curvature (m).

Return type:

float or ndarray
