Compute the initial and final bearing (forward and reverse azimuth) from this to an other point, using this `Inverse` method. See methods initialBearingTo and finalBearingTo for more details. Arguments: `other` - The other point (this `LatLon`). `wrap` - If `True`, wrap or normalize and unroll the `other` point (`bool`). Returns: A Bearing2Tuple`(initial, final)`. Raises: `TypeError` - If `other` not this `LatLon` class. `ValueError` - If this and the `other` point's Datum ellipsoids are not compatible.

### destination (self, distance, bearing, height=None) |

### destination2 (self, distance, bearing, height=None) |
Compute the destination point and the final bearing (reverse azimuth) after having travelled for the given distance from this point along a geodesic (line) given by an initial bearing at this point. The distance must be in the same units as this point's datum's ellipsoid's axes, conventionally `meter`. The distance is measured on the surface of the ellipsoid, ignoring this point's height. The initial and final bearing (forward and reverse azimuth) are in compass `degrees360`, clockwise from North. The destination point's height and datum are set to this point's height and datum, unless the former is overridden.

### distanceTo3 (self, other, wrap=False) |
Compute the distance, the initial and final bearing along a geodesic between this and an other point, using this `Inverse` method. The distance is in the same units as this point's datum's ellipsoid's axes, conventionally meter. The distance is measured on the surface of the ellipsoid, ignoring this point's height.
