wavespectra.partition.partition.Partition.bbox

Partition.bbox(bboxes)

Partition based on user-defined bounding boxes in frequency-direction space.

BBOX partitions the spectra based on user-defined bounding boxes in frequency-direction space.

Args:

• bboxes (list(dict)): List of dictionaries with keys fmin, fmax, dmin and dmax specifying the boundaries of each bounding box.

Returns:

• dspart (xr.Dataset): Partitioned spectra with extra part dimension with indices ordered as in the list of dictionaries.

Note:

• Non-specified bounds in each bbox dict are defined from the bounds of the freq / dir bounds in the spectrum, e.g., fmin=min(freq).

• Bounding boxes must not overlap.

• Last part index is defined by spectral bins not covered by any bboxes.

TODO: Deal with directions crossing 360.
