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.

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.
