Method Details

### __init__ (self, east_enu, north=0, up=0, ltp=None, **name) (Constructor) |
New Enu. Arguments: `east_enu` - Scalar East component (`meter`) or a previous local instance (Enu, Enu4Tuple, Aer, Aer4Tuple, Local9Tuple, Ned, Ned4Tuple, XyzLocal or Xyz4Tuple). `north` - Scalar North component (`meter`), iff `east_enu` is `meter`, ignored otherwise. `up` - Scalar Up component (`meter`, normal from the surface of the ellipsoid or sphere), iff `east_enu` is `meter`, ignored otherwise. `ltp` - The local tangent plane, (geodetic) origin (Ltp, LocalCartesian). `name` - Optional `name=NN` (`str`). Raises: `TypeError` - Invalid `east_enu` or `ltp`. `UnitError` - Invalid `east_enu`, `north` or `up`. Overrides: object.__init__

### toUvw (self, location, Uvw=None, **name_Uvw_kwds) |
Get the u, v, w (UVW) components at a location. Arguments: `location` - The geodetic (`LatLon`) or geocentric (`Cartesian`, Vector3d) location, like a Point-Of-View. `Uvw` - Class to return UWV (Uvw) or `None`. `name_Uvw_kwds` - Optional `name=NN` (`str`) and optionally, additional Uvw keyword arguments, ignored if `Uvw is None`. Returns: A `Uvw` instance or a Uvw3Tuple`(u, v, w)` if `Uvw is None`. Raises: `TypeError` - Invalid `location` or `name_Uvw_kwds` item. See Also: Function lookAtSpheroid.

Property Details

### xyzLocal Get this ENU as an XyzLocal. Get method: xyzLocal(self) - Get this ENU as an XyzLocal. Set method: _fset_error(inst, val) - Throws an `AttributeError`, always. Delete Method: _fdel(inst) - Zap the cached/memoized `property` value.
