xrspatial.zonal.regions(raster: xarray.core.dataarray.DataArray, neighborhood: int = 4, name: str = 'regions') → xarray.core.dataarray.DataArray[source]¶ Create unique regions of raster based on pixel value connectivity. Connectivity can be based on either 4 or 8-pixel neighborhoods. Output raster contain a unique int for each connected region.
