While tracing and digitizing rivers, streams, rivulets, etc., is it possible to indicate the direction/flow in the shapefile on QGIS?
I'd like to avoid using map labels. Ideally, when done tracing, I would like to change the symbology to a line pattern of tiny arrows showing the flow direction.
Some similar questions I've found here deal with elevation and contours obtained from DEM materials. Although I am also working with DEM files, I would like to be able to work this without using the ASTER material and simply input it myself since I know the flow direction.
