                                               LatLon

New point on an (oblate) ellipsoidal earth model, using the formulae devised by Thaddeus Vincenty (1975) to compute geodesic distances, bearings (azimuths), etc.

Set the earth model to be used with the keyword argument datum. The default is `Datums.WGS84`, which is the most globally accurate. For other models, see the Datums.

Note: This implementation of Vincenty methods may not converge for some valid points, raising a VincentyError. In that case, a result may be obtained by increasing the tolerance `epsilon` and/or iteration `limit`, see properties LatLon.epsilon and LatLon.iterations.

Instance Methods
bearingTo(self, other, wrap=False) DEPRECATED, use method initialBearingTo or bearingTo2. |
toCartesian(self, **Cartesian_datum_kwds) Convert this point to `Vincenty`-based cartesian (ECEF) coordinates. |

Method Details

### bearingTo (self, other, wrap=False) |
DEPRECATED, use method initialBearingTo or bearingTo2. Decorators: `@deprecated_method`

### toCartesian (self, **Cartesian_datum_kwds) |
Convert this point to `Vincenty`-based cartesian (ECEF) coordinates. Arguments: `Cartesian_datum_kwds` - Optional Cartesian, `datum` and other keyword arguments, ignored if `Cartesian=None`. Use `Cartesian=...` to override this Cartesian class or specify `Cartesian=None`. Returns: The cartesian point (Cartesian) or if `Cartesian` is `None`, an Ecef9Tuple`(x, y, z, lat, lon, height, C, M, datum)` with `C` and `M` if available. Raises: `TypeError` - Invalid `Cartesian`, `datum` or other `Cartesian_datum_kwds`. Overrides: latlonBase.LatLonBase.toCartesian

Property Details

### Ecef Get the ECEF class (EcefVeness), once. Get method: Ecef(self) - Get the ECEF class (EcefVeness), once. Set method: _fset_error(inst, val) - Throws an `AttributeError`, always. Delete Method: _fdel(inst) - Zap the cached/memoized `property` value.

### epsilon Class `property` with retrievable name. Get method: epsilon(self) - Get the convergence epsilon (`radians`). Set method: epsilon(self, epsilon) - Set the convergence epsilon (`radians`).

### iterations Class `property` with retrievable name. Get method: iterations(self) - Get the iteration limit (`int`). Set method: iterations(self, limit) - Set the iteration limit (`int`).
