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) only used with scalar east_enu.
up - Scalar Up component only used with scalar east_enu, normal from the surface of the ellipsoid or sphere (meter).
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 optional, additional Uvw keyword arguments, ignored if Uvw is None.

Returns:

UVW as a Uvw instance or if

Uvw is 
          None

, a Uvw3Tuple(u, v, w).

Raises:

TypeError - Invalid location or name_Uvw_kwds.

Property Details

xyzLocal

Get method:: _fget(inst) - Get and cache/memoize the property value.
Set method:: _fset_error(inst, val) - Throws an AttributeError, always.
Delete Method:: _fdel(inst) - Zap the cached/memoized property value.
