Method Details

### to3llh(self, datum=Datum(name='WGS84', ellipsoid=Ellipsoids.WGS84, transform=Tran`...`) |
Convert this (geocentric) Cartesian (x/y/z) point to (ellipsoidal, geodetic) lat-, longitude and height on the given datum. Uses Bowring’s (1985) formulation for μm precision in concise form: 'The accuracy of geodetic latitude and height equations', B. R. Bowring, Survey Review, Vol 28, 218, Oct 1985. 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, from Lawrence Livermore National Laboratory. Parameters: `datum` - Optional datum to use (Datum). Returns: 3-Tuple (lat, lon, heigth) in (`degrees90`, `degrees180`, `meter`).

### toStr(self, prec=3, fmt=`'``[%s]``'`, sep=`'``,` `'`) |
Return the string representation of this cartesian. Parameters: `prec` - Optional number of decimals, unstripped (`int`). `fmt` - Optional enclosing backets format (string). `sep` - Optional separator to join (string). Returns: Cartesian represented as "[x, y, z]" (string). Overrides: bases.Based.toStr
