pyflwdir.FlwdirRaster.outflow_idxs

FlwdirRaster.outflow_idxs(region: ndarray) → ndarray

Return linear indices of the most downstream cells within a region.

Parameters:

region (2D array of bool) – True for cells inside the region.

Returns:

Linear indices of the most downstream cells in region.

Return type:

1D array of int

Notes

The cells are the same for every ordering set with order_cells (see its Notes). They follow the sequence though, so their order changes with the method.
