Instance Methods

__init__(self, epoch, datum=Datum(name='GRS80', ellipsoid=Ellipsoids.GRS80, transform=Tran..., name='')
New RefFrame.

__eq__(self, other)

__lt__(self, other)

__matmul__(self, point)
DEPRECATED on 2024.02.16, use method point.toRefFrame.

toRefFrame(self, point, reframe2, **epoch_epoch2_name)
Convert an ellipsoidal point from this reframe and from epoch to an other reframe2 and epoch2 or epoch.

toStr(self, epoch=None, name='', **unused)
Return this reference frame as a string.

Xform(self, reframe2)
Get the converter Xform from this reference frame to reframe2.

Xforms(self, inverse=False)
Return all Xforms converting from or to this reference frame or both.

Method Details

init (self, epoch, datum=Datum(name='GRS80', ellipsoid=Ellipsoids.GRS80, transform=Tran`...`, name='')
(Constructor)

New RefFrame.

Arguments:

epoch - Epoch, a fractional calendar year (scalar or str).
datum - Datum or ellipsoid (Datum, {Ellipsoid}, Ellipsoid2 or a_f2Tuple).
name - Unique, non-empty name (str).

Raises:

NameError - A RefFrame with that name already exists.
TRFError - Invalid epoch.
TypeError - Invalid datum.

Overrides: object.__init__

matmul (self, point)

DEPRECATED on 2024.02.16, use method point.toRefFrame.

Decorators:

@deprecated_method

Overrides: named._Named.__matmul__

toRefFrame (self, point, reframe2, **epoch_epoch2_name)

Convert an ellipsoidal point from this reframe and from epoch to an other reframe2 and epoch2 or epoch.

Arguments:

point - The point to convert (LatLon or Cartesian).
reframe2 - Reference frame to convert to (RefFrame).
epoch_epoch2_name - Optional keyword arguments epoch=None, epoch2=None and name=reframe2.name.

Returns:

A copy of the point, converted and renamed.

Raises:

TypeError - Invalid point.

Note: The point.reframe is overridden by this reframe and point.epoch by epoch or this reframe.epoch.

See Also: Methods LatLon.toRefFrame and Cartesian.toRefFrame for more details.

toStr (self, epoch=None, name='', **unused)

Return this reference frame as a string.

Arguments:

epoch - Override this reframe's epoch (scalar or str).
name - Override name (str) or None to exclude the reframe's name.

Returns:

This RefFrame's attributes (str).

Overrides: named._Named.toStr

Xform (self, reframe2)

Get the converter Xform from this reference frame to reframe2.

Arguments:

reframe2 - Destination frame to convert to (RefFrame or str).

Returns:

The TRFXform instance or None if not available.

Raises:

TypeError - Invalid reframe2.

Xforms (self, inverse=False)

Return all Xforms converting from or to this reference frame or both.

Arguments:

inverse - If True, get all from otherwise to Xforms un-inverted (bool) or if inverse=2 (int) get all to Xforms inverted plus all froms.

Returns:

An ADict of name=TRFXforms from this reframe or if inverse=True to this reframe or both if inverse=2.
