                    PhiLam2Tuple

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

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

Method Details

### to3Tuple (self, height) |
Extend this PhiLam2Tuple to a PhiLam3Tuple. Arguments: `height` - The height to add (`scalar`). Returns: A PhiLam3Tuple`(phi, lam, height)`. Raises: `ValueError` - Invalid `height`.

### to4Tuple (self, height, datum) |
Extend this PhiLam2Tuple to a PhiLam4Tuple. Arguments: `height` - The height to add (`scalar`). `datum` - The datum to add (`Datum`). Returns: A PhiLam4Tuple`(phi, lam, height, datum)`. Raises: `TypeError` - If `datum` not a `Datum`. `ValueError` - Invalid `height`.
