                   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 Named-Tuple item.

Note: Specify at least 2 item names.

Value:
('phi', 'lam', 'height')

_Units_

Tuple defining the units of the value of each Named-Tuple item.

Note: The len(_Units_) must match len(_Names_).

Value:
(<class 'pygeodesy.units.Phi'>,
 <class 'pygeodesy.units.Lam'>,
 <class 'pygeodesy.units.Height'>)
