pyflwdir.FlwdirRaster.moving_median#

FlwdirRaster.moving_median(data: ndarray, n: int, restrict_strord: bool = False, strord: ndarray | None = None, nodata: float = -9999.0) → ndarray#

Take the moving median over the flow direction network

Parameters:

  • data (array-like) – Values associated with graph cells. Use a 1D array for Flwdir and an array matching the raster shape for FlwdirRaster.

  • n (int) – number of up/downstream neighbors to include

  • restrict_strord (bool) – If True, limit the window to cells of same or smaller stream order.

  • strord (array-like of int, optional) – Stream-order map used when restrict_strord is True.

  • nodata (float, optional) – Nodata values which is ignored when calculating the median, by default -9999.0

Returns:

Median values, with the same shape as data.

Return type:

array
