Method Details

### __init__(self, xyz, y=None, z=None, datum=None, ll=None, name=`'````'`) (Constructor) |
New `Cartesian...`. Parameters: `xyz` - An Ecef9Tuple, Vector3Tuple, Vector4Tuple or the `X` coordinate (`scalar`). `y` - The `Y` coordinate (`scalar`) if `xyz` `scalar`. `z` - The `Z` coordinate (`scalar`) if `xyz` `scalar`. `datum` - Optional datum (Datum). `ll` - Optional, original latlon (`LatLon`). `name` - Optional name (`str`). Raises: `TypeError` - Non-scalar `xyz`, `y` or `z` coordinate or `xyz` not an Ecef9Tuple, Vector3Tuple or Vector4Tuple. Overrides: object.__init__

### convertDatum(self, datum2, datum=None) |
Convert this cartesian from one datum to an other. Parameters: `datum2` - Datum to convert to (Datum). `datum` - Datum to convert from (Datum). Returns: The converted point (`Cartesian`). Raises: `TypeError` - `datum2` or `datum` not a Datum.

### to3llh(self, datum=None) |
DEPRECATED, use property `latlonheightdatum` or property `latlonheight`. Returns: A LatLon4Tuple`(lat, lon, height, datum)`. Note: This method returns a `-4Tuple` and not a `-3Tuple` as its name suggests.

### toEcef(self) |
Convert this cartesian to geodetic (lat-/longitude) coordinates. Returns: An Ecef9Tuple`(x, y, z, lat, lon, height, C, M, datum)` with `C` and `M` if available. Raises: `EcefError` - A `.datum` or an ECEF issue.

### toLatLon(self, datum=None, LatLon=None, **LatLon_kwds) |
Convert this cartesian to a geodetic (lat-/longitude) point. Parameters: `datum` - Optional datum (Datum) or `None`. `LatLon` - Optional class to return the geodetic point (`LatLon`) or `None`. `LatLon_kwds` - Optional, additional `LatLon` keyword arguments, ignored if `LatLon=None`. Returns: The geodetic point (`LatLon`) or if `LatLon` is `None`, an Ecef9Tuple`(x, y, z, lat, lon, height, C, M, datum)` with `C` and `M` if available. Raises: `TypeError` - Invalid `datum` or `LatLon_kwds`.

### toNvector(self, Nvector=None, datum=None, **Nvector_kwds) |
Convert this cartesian to `n-vector` components. Parameters: `Nvector` - Optional class to return the `n-vector` components (`Nvector`) or `None`. `datum` - Optional datum (Datum) overriding this cartesian's datum. `Nvector_kwds` - Optional, additional `Nvector` keyword arguments, ignored if `Nvector=None`. Returns: The `unit, n-vector` components (`Nvector`) or a Vector4Tuple`(x, y, z, h)` if `Nvector` is `None`. Raises: `ValueError` - The `Cartesian` at origin. Example:
    >>> c = Cartesian(3980581, 97, 4966825)
    >>> n = c.toNvector()  # (x=0.622818, y=0.00002, z=0.782367, h=0.242887)

### toStr(self, prec=3, fmt=`'``[%s]``'`, sep=`'``,` `'`) |
Return the string representation of this cartesian. Parameters: `prec` - Optional number of decimals, unstripped (`int`). `fmt` - Optional enclosing backets format (string). `sep` - Optional separator to join (string). Returns: Cartesian represented as "[x, y, z]" (string). Raises: `AssertionError` - Always, see function notOverloaded. Overrides: named._Named.toStr

### toVector(self, Vector=None, **Vector_kwds) |
Return this cartesian's components as vector. Parameters: `Vector` - Optional class to return the `n-vector` components (Vector3d) or `None`. `Vector_kwds` - Optional, additional `Vector` keyword arguments, ignored if `Vector=None`. Returns: A `Vector` or an Vector3Tuple`(x, y, z)` if `Vector` is `None`. Raises: `TypeError` - Invalid `Vector` or `Vector_kwds`.
