                       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, **name) |
Extend this PhiLam3Tuple to a PhiLam4Tuple. Arguments: `datum` - The datum to add (`Datum`). `name` - Optional `name=NN` (`str`), overriding this name. Returns: A PhiLam4Tuple`(phi, lam, height, datum)`. Raises: `TypeError` - If `datum` not a `Datum`.
