code: def get_segmentize_value(input_file=None, tile_pyramid=None):
      
      with rasterio.open(input_file, "r") as input_raster:
          pixelsize = input_raster.transform[0]
      return pixelsize * tile_pyramid.tile_size
docs: Return the recommended segmentation value in input file units.
  
      It is calculated by multiplyling raster pixel size with tile shape in
      pixels.
  
      Parameters
      ----------
      input_file : str
          location of a file readable by rasterio
      tile_pyramied : ``TilePyramid`` or ``BufferedTilePyramid``
          tile pyramid to estimate target tile size
  
      Returns
      -------
      segmenize value : float
          length suggested of line segmentation to reproject file bounds
