I have river network in QGIS. I draw opposite direction one of the rivers. Now I want to change direction of that river.
How can I do that in QGIS 3?
(As I know it is flip in ArcGIS)
If you want to reverse selected crossection lines in QGIS3.X, I recommend the plugin--digitizingtools. Of course it works well in qgis3.x. And at its tool bar, you can see flip line tool. Enjoy youself!
