Method Details

### reverse (self, xyz, y=None, z=None, M=None, name='') |
Convert 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` - Optional name (`str`). 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 See Also: Ralph M. Toms 'An Efficient Algorithm for Geocentric to Geodetic Coordinate Conversion', Sept 1995 and 'An Improved Algorithm for Geocentric to Geodetic Coordinate Conversion', Apr 1996, both from Lawrence Livermore National Laboratory (LLNL) and John J.
