Method Details

### __init__(self, x, y=None, z=None, h=0, ll=None, datum=None, name=`'````'`) (Constructor) |
New n-vector normal to the earth's surface. Parameters: `x` - An `Nvector`, Vector3Tuple, Vector4Tuple or the `X` coordinate (`scalar`). `y` - The `Y` coordinate (`scalar`) if `x` `scalar`. `z` - The `Z` coordinate (`scalar`) if `x` `scalar`. `h` - Optional height above surface (`meter`). `ll` - Optional, original latlon (`LatLon`). `datum` - Optional, pass-thru datum (`Datum`). `name` - Optional name (`str`). Raises: `TypeError` - Non-scalar `x`, `y` or `z` coordinate or `x` not an `Nvector`, Vector3Tuple or Vector4Tuple. Overrides: object.__init__ Example:
    >>> from pygeodesy.sphericalNvector import Nvector
    >>> v = Nvector(0.5, 0.5, 0.7071, 1)
    >>> v.toLatLon()  # 45.0°N, 045.0°E, +1.00m

### to3abh(self, height=None) |
Convert this n-vector to (geodetic) lat-, longitude in `radians` and height. Parameters: `height` - Optional height, overriding this n-vector's height (`meter`). Returns: A PhiLam3Tuple`(phi, lam, height)`.

### to3llh(self, height=None) |
Convert this n-vector to (geodetic) lat-, longitude in `degrees` and height. Parameters: `height` - Optional height, overriding this n-vector's height (`meter`). Returns: A LatLon3Tuple`(lat, lon, height)`.

### to4xyzh(self, h=None) |
Return this n-vector's components as 4-tuple. Parameters: `h` - Optional height, overriding this n-vector's height (`meter`). Returns: A Vector4Tuple`(x, y, z, h)`.

### toCartesian(self, h=None, Cartesian=None, datum=None, **kwds) |
Convert this n-vector to `Nvector`-based cartesian (ECEF) coordinates. Parameters: `height` - Optional height, overriding this n-vector's height (`meter`). `Cartesian` - Optional (sub-)class to return the (ECEF)coordinates (`Cartesian`). `datum` - Optional, spherical datum (`Datum`). `kwds` - Optional, additional `name=value` pairs for `Cartesian` instance, provided `Cartesian` is not `None`. Returns: Cartesian (ECEF) coordinates (`Cartesian`). Raises: `TypeError` - Invalid `Cartesian`. Example:
