                   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, **name)

Extend this PhiLam2Tuple to a PhiLam3Tuple.

Arguments:

height - The height to add (scalar).
name - Optional name=NN (str), overriding this name.

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.
