Method Details

### bearingTo2 (self, other, wrap=False) |
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 (`LatLon`). `wrap` - Wrap and unroll longitudes (`bool`). Returns: A Bearing2Tuple`(initial, final)`. Raises: `TypeError` - The `other` point is not `LatLon`. `ValueError` - If this and the `other` point's Datum ellipsoids are not compatible.

### destination (self, distance, bearing, height=None) |
Compute the destination point after having travelled for the given distance from this point along a geodesic given by an initial bearing, using this `Direct` method. See method destination2 for more details. Arguments: `distance` - Distance (`meter`). `bearing` - Initial bearing in (compass `degrees360`). `height` - Optional height, overriding the default height (`meter`, same units as `distance`). Returns: The destination point (`LatLon`).

### 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 given by an initial bearing, using this `Direct` method. The distance must be in the same units as this point's datum 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`. The destination point's height and datum are set to this point's height and datum, unless the former is overridden. Arguments: `distance` - Distance (`meter`). `bearing` - Initial bearing (compass `degrees360`). `height` - Optional height, overriding the default height (`meter`, same units as `distance`). Returns: A Destination2Tuple`(destination, final)`.

### distanceTo (self, other, wrap=False, **unused) |
Compute the distance between this and an other point along a geodesic, using this `Inverse` method. See method distanceTo3 for more details. Arguments: `other` - The other point (`LatLon`). `wrap` - Wrap and unroll longitudes (`bool`). Returns: Distance (`meter`). Raises: `TypeError` - The `other` point is not `LatLon`. `ValueError` - If this and the `other` point's Datum ellipsoids are not compatible.

### 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 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` from North. Arguments: `other` - Destination point (`LatLon`). `wrap` - Wrap and unroll longitudes (`bool`). Returns: A Distance3Tuple`(distance, initial, final)`. Raises: `TypeError` - The `other` point is not `LatLon`. `ValueError` - If this and the `other` point's Datum ellipsoids are not compatible.

### finalBearingOn (self, distance, bearing) |
Compute the final bearing (reverse azimuth) after having travelled for the given distance along a geodesic given by an initial bearing from this point, using this `Direct` method. See method destination2 for more details. Arguments: `distance` - Distance (`meter`). `bearing` - Initial bearing (compass `degrees360`). Returns: Final bearing (compass `degrees360`).

### finalBearingTo (self, other, wrap=False) |
Compute the final bearing (reverse azimuth) after having travelled along a geodesic from this point to an other point, using this `Inverse` method. See method distanceTo3 for more details. Arguments: `other` - The other point (`LatLon`). `wrap` - Wrap and unroll longitudes (`bool`). Returns: Final bearing (compass `degrees360`). Raises: `TypeError` - The `other` point is not `LatLon`. `ValueError` - If this and the `other` point's Datum ellipsoids are not compatible.

### initialBearingTo (self, other, wrap=False) |
Compute the initial bearing (forward azimuth) to travel along a geodesic from this point to an other point, using this `Inverse` method. See method distanceTo3 for more details. Arguments: `other` - The other point (`LatLon`). `wrap` - Wrap and unroll longitudes (`bool`). Returns: Initial bearing (compass `degrees360`). Raises: `TypeError` - The `other` point is not `LatLon`. `ValueError` - If this and the `other` point's Datum ellipsoids are not compatible.

### intermediateTo (self, other, fraction, height=None, wrap=False) |
Return the point at given fraction along the geodesic between this and an other point, using this `Direct` and `Inverse` methods. Arguments: `other` - The other point (`LatLon`). `fraction` - Fraction between both points ranging from 0, meaning this to 1, the other point (`float`). `height` - Optional height, overriding the fractional height (`meter`). `wrap` - Wrap and unroll longitudes (`bool`). Returns: Intermediate point (`LatLon`). Raises: `TypeError` - The `other` point is not `LatLon`. `UnitError` - Invalid `fraction` or `height`. `ValueError` - If this and the `other` point's Datum ellipsoids are not compatible. See Also: Methods distanceTo3 and destination.

Property Details

### geodesic N/A, invalid (`None` always). Get method: geodesic(self) - N/A, invalid (`None` always). Set method: _fset_error(inst, val) - Throws an `AttributeError`, always. Delete Method: _fdel(inst) - Zap the cached/memoized `property` value.
