- pygplates.reverse_reconstruct(reconstructable_features, rotation_model, reconstruction_time[, anchor_plate_id])
Reverse reconstruct geological features from a specific geological time.
FeatureCollection, or string, or
Feature, or sequence of
Feature, or sequence of any combination of those four types) – A reconstructable feature collection, or filename, or feature, or sequence of features, or a sequence (eg,
tuple) of any combination of those four types - all features used as input and output
FeatureCollectionor string or sequence of
FeatureCollectioninstances and/or strings) – A rotation model or a rotation feature collection or a rotation filename or a sequence of rotation feature collections and/or rotation filenames
anchor_plate_id (int) – The anchored plate id used during reverse reconstruction. Defaults to the default anchor plate of rotation_model.
OpenFileForReadingError if any input file is not readable (when filenames specified)
OpenFileForWritingError if reconstructable_features specifies any filename that is not writeable (if any filenames are specified)
FileFormatNotSupportedError if any input file format (identified by any reconstructable and rotation filename extensions) does not support reading (when filenames specified)
The effect of this function is to replace the present day geometries in each feature in reconstructable_features with reverse reconstructed versions of those geometries. This assumes that the original geometries, stored in reconstructable_features, are not in fact present day geometries (as they normally should be) but instead the already-reconstructed geometries corresponding to geological time reconstruction_time. This function reverses that reconstruction process to ensure present day geometries are stored in the features.
Note that reconstructable_features can be a
FeatureCollectionor a filename or a feature or a sequence of features, or a sequence (eg,
tuple) of any combination of those four types.
If any filenames are specified in reconstructable_features then the modified feature collection(s) (containing reverse reconstructed geometries) that are associated with those files are written back out to those same files.
Note that rotation_model can be either a
RotationModelor a rotation
FeatureCollectionor a rotation filename or a sequence (eg,
tuple) containing rotation
FeatureCollectioninstances or filenames (or a mixture of both). When a
RotationModelis not specified then a temporary one is created internally (and hence is less efficient if this function is called multiple times with the same rotation data).
Reverse reconstructing a file containing a feature collection from 10Ma:
pygplates.reverse_reconstruct('volcanoes.gpml', rotation_model, 10)
Reverse reconstructing a feature collection from 10Ma:
pygplates.reverse_reconstruct(pygplates.FeatureCollection([feature1, feature2]), rotation_model, 10)
Reverse reconstructing a list of features from 10Ma:
pygplates.reverse_reconstruct([feature1, feature2], rotation_model, 10)
Reconstructing a single feature from 10Ma:
pygplates.reconstruct(feature, rotation_model, 10)
Changed in version 0.29: The
geometry import timeis set to reconstruction_time.
