pygeodesy.ecef.EcefVeness

Conversion between geodetic and geocentric, Earth-Centered, Earth-Fixed (ECEF) coordinates transcoded from Chris Veness' JavaScript classes LatLonEllipsoidal, Cartesian.

reverse (self, xyz, y=None, z=None, M=None, **name_lon00)

Conversion from geocentric (x, y, z) to geodetic (lat, lon, height) transcoded from Chris Veness' JavaScript.

Uses B. R. Bowring’s formulation for μm precision in concise form The accuracy of geodetic latitude and height equations, Survey Review, Vol 28, 218, Oct 1985.

Arguments:

xyz - A geocentric (Cartesian, Ecef9Tuple) or scalar ECEF x coordinate (meter).
y - ECEF y coordinate for scalar xyz and z (meter).
z - ECEF z coordinate for scalar xyz and y (meter).
M - Ignored, rotation matrix M not available.
name_lon00 - Optional keyword arguments name=NN (str) and "polar" longitude lon00=INT0 (degrees), overriding the default and property lon00 setting and returned in case x=0 and y=0.

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 C, M=None always and datum if available.

Raises:

EcefError - Invalid xyz or scalar x or y and/or z not scalar for scalar xyz.

Overrides: _EcefBase.reverse
