Direction of measurement (Optional) | The direction of measurement along the flow path.
| String |
Input weight raster (Optional) | An optional input raster for applying a weight to each cell. If no weight raster is specified, a default weight of 1 will be applied to each cell. For each cell in the output raster, the result will be the number of cells that flow into it. | Raster Layer |
