xoa.filter.erode_coast(data, until=1, kernel=None, xdim=None, ydim=None)[source]#

Just like erode_mask() but specialized for the horizontal dimensions

Parameters:

  • data (xarray.DataArray) – Array of at least 2 dimensions, that are supposed to be horizontal.

  • until (array_like, int) – Either a minimal mask, or a max number of iteration.

  • kernel – Defaults to a shapiro kernel. In this case, xdim and ydim can be set to the horizontal dimensions, otherwise they are inferred.

  • xdim (None) – Name of the X dimension, which is infered by default.

  • ydim (None) – Name of the Y dimension, which is infered by default.

Returns:

xarray.DataArray – Data array similar to input array, with its eroded along x and y dimensions.
