                       PhiLam3Tuple

3-Tuple `(phi, lam, height)` with latitude `phi` in `radians[PI_2]`, longitude `lam` in `radians[PI]` and `height` in `meter`.

Note: Using `phi/lambda` for lat-/longitude in `radians` follows Chris Veness' convention.

Method Details

### to4Tuple (self, datum) |
Extend this PhiLam3Tuple to a PhiLam4Tuple. Arguments: `datum` - The datum to add (`Datum`). Returns: A PhiLam4Tuple`(phi, lam, height, datum)`. Raises: `TypeError` - If `datum` not a `Datum`.

Class Variable Details

  ### _Names_ Tuple specifying the `name` of each -Tuple item. Note: Specify at least 2 item names. Value:
      ('phi', 'lam', 'height')

  ### _Units_ Tuple defining the `units` of the value of each -Tuple item. Note: The `len(_Units_)` must match `len(_Names_)`. Value:
      (<class 'pygeodesy.units.Phi'>,
       <class 'pygeodesy.units.Lam'>,
       <class 'pygeodesy.units.Height'>)
