                      EcefSudano

Conversion between geodetic and geocentric, Earth-Centered, Earth-Fixed (ECEF) coordinates based on John J. Sudano's paper.

Instance Methods

reverse(self, xyz, y=None, z=None, M=False, tol=2.220446049250313e-16, **lon00_name)
Convert from geocentric (x, y, z) to geodetic (lat, lon, height) using Sudano's iterative method.

Method Details

reverse (self, xyz, y=None, z=None, M=False, tol=2.220446049250313e-16, **lon00_name)

Convert from geocentric (x, y, z) to geodetic (lat, lon, height) using Sudano's iterative method.

Arguments:

tol - Convergence tolerance for sin(latitude) (scalar).

Returns:

An Ecef9Tuple

(x, y, z, lat, lon, height, C, 
          M, datum)

with geodetic coordinates

(lat, lon, 
          height)

for the given geocentric ones

(x, y, 
          z)

, case indicator C (int 1..5), rotation matrix M (EcefMatrix or None) and datum.

Raises:

EcefError - Invalid xyz or scalar x or y and/or z not scalar for scalar xyz or no convergence for tol.

Overrides: _EcefBase.reverse
