Display Flow Directions on ground surface by ArcGIS
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.
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?
