pygplates.ReconstructedFlowline
- class pygplates.ReconstructedFlowline
Bases:
pygplates.ReconstructionGeometry
The reconstructed history of plate motion away from a spreading ridge in the form of a path of points over geological time.
The
reconstruct()
function can be used to generate ReconstructedFlowline instances.Note
Although a single flowlinefeature
has only a single seed geometry that seed geometry can be either aPointOnSphere
or aMultiPointOnSphere
.And since there is onereconstructed flowline
per seed point there can be, in the case of aMultiPointOnSphere
, multiplereconstructed flowlines
per flowlinefeature

Methods
Raises an exception This class cannot be instantiated from Python
Returns the feature associated with this
ReconstructedFlowline
.Returns the flowline spread along the left plate from the reconstructed seed point.
Returns the present day seed point.
Returns the feature property containing the seed point associated with this
ReconstructedFlowline
.Returns the reconstructed seed point.
get_reconstruction_time
()Returns the reconstruction time that this instance was created at.
Returns the flowline spread along the right plate from the reconstructed seed point.
- get_feature()
Returns the feature associated with this
ReconstructedFlowline
.- Return type
Note
Multiple
reconstructed flowlines
can be associated with the same flowlinefeature
if its seed geometry is aMultiPointOnSphere
.
- get_left_flowline()
Returns the flowline spread along the left plate from the reconstructed seed point.
- Return type
The returned points are on the left plate associated with
get_feature().get_left_plate()
The first point in the returned
PolylineOnSphere
is thereconstructed seed point
and subsequent points are progressively further in the geological past.Note
This is just one of the left flowlines associated with this
feature's
seed geometry if that seed geometry is aMultiPointOnSphere
.Iterate over the left flowline points:
for left_point in reconstructed_flowline.get_left_flowline(): ...
- get_present_day_seed_point()
Returns the present day seed point.
- Return type
Note
This is just one of the seed points in this
feature's
seed geometry if that seed geometry is aMultiPointOnSphere
. The remaining seed points are associated with otherReconstructedFlowline
instances.
- get_property()
Returns the feature property containing the seed point associated with this
ReconstructedFlowline
.- Return type
This is the
Property
that thepresent day seed point
and thereconstructed seed point
are obtained from.
- get_reconstructed_seed_point()
Returns the reconstructed seed point.
- Return type
Note
This is just one of the seed points in this
feature's
seed geometry if that seed geometry is aMultiPointOnSphere
. The remaining seed points are associated with otherReconstructedFlowline
instances.
- get_right_flowline()
Returns the flowline spread along the right plate from the reconstructed seed point.
- Return type
The returned points are on the right plate associated with
get_feature().get_right_plate()
The first point in the returned
PolylineOnSphere
is thereconstructed seed point
and subsequent points are progressively further in the geological past.Note
This is just one of the right flowlines associated with this
feature's
seed geometry if that seed geometry is aMultiPointOnSphere
.Iterate over the right flowline points:
for right_point in reconstructed_flowline.get_right_flowline(): ...
