  Hi Water Networks Fellows, I am a GIS Engineer. I would like to gently ask about flow directions by ArcGIS or QGIS. I've a size of dem 0.1m by 0.1m. I would like to draw raster file as below.    questions :   1. How to do it to generate the DEM like above?   2. All of path are arrow shapes, is it possible to generate like it?   Thanks.
