WebThe Watershed tool only supports a D8-type of input flow direction raster. This can be created using the Flow Direction tool, run with default flow direction type D8 (in Python, with the D8 option). Better results will be obtained if the Snap Pour Point tool is used beforehand to help locate the pour points to cells of high accumulated flow. Webwatershed segmentations based on user-supplied seeds --- then this Python module is not for you and you should use the OpenCV implementation. With regard to the speed of execution, a pure Python module such as this cannot hope to compete with the C-based implementation in the OpenCV library.
