Method Details

init (self, a_earth=Datum(name='WGS84', ellipsoid=Ellipsoids.WGS84, transform=Tran`...`, f=None, exact=True, **RA_TMorder_name)
(Constructor)

New Rhumb.

Arguments:

a_earth - This rhumb's earth model (Datum, Ellipsoid, Ellipsoid2, a_f2Tuple, 2-tuple (a, f)) or the (equatorial) radius (meter, conventionally).
f - The ellipsoid's flattening (scalar), required if a_earth is scalar, ignored otherwise.
exact - If True, use an addition theorem for elliptic integrals to compute Divided differences, otherwise use the Krüger series expansion (bool or None), see also properties exact and TMorder.
RA_TMorder_name - Optional name=NN (str) and optional keyword arguments RAorder=6 and TMorder=6 to set the respective order, see properties RAorder and TMorder.

Raises:

RhumbError - Invalid a_earth, f, RAorder or TMorder.

Overrides: object.__init__

Direct7 (self, lat1, lon1, azi12, s12, outmask=16792)

DEPRECATED, use method Rhumb.Direct8.

Returns:

A DEPRECATED Rhumb7Tuple.

Decorators:

@deprecated_method

Inverse7 (self, lat1, lon1, azi12, s12, outmask=17937)

DEPRECATED, use method Rhumb.Inverse8.

Returns:

A DEPRECATED Rhumb7Tuple.

Decorators:

@deprecated_method

orders (self, RAorder=6, TMorder=6)

DEPRECATED, use properties RAorder and/or TMorder.

Get and set the RAorder and/or TMorder.

Arguments:

RAorder - Rhumb Area order (int, 4, 5, 6, 7 or 8).
TMorder - Transverse Mercator order (int, 4, 5, 6, 7 or 8).

Returns:

DEPRECATED RhumbOrder2Tuple(RAorder, TMorder) with the previous RAorder and TMorder setting.

Decorators:

@deprecated_method

Property Details

RAorder

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