Method Details

### to3Tuple (self, height) |
Extend this LatLon2Tuple to a LatLon3Tuple. Arguments: `height` - The height to add (`scalar`). Returns: A LatLon3Tuple`(lat, lon, height)`. Raises: `ValueError` - Invalid `height`.

### to4Tuple (self, height, datum) |
Extend this LatLon2Tuple to a LatLon4Tuple. Arguments: `height` - The height to add (`scalar`). `datum` - The datum to add (`Datum`). Returns: A LatLon4Tuple`(lat, lon, height, datum)`. Raises: `TypeError` - If `datum` not a `Datum`. `ValueError` - Invalid `height`.

Class Variable Details

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

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