I am trying to create some contour lines that are around cliff faces. What is the best way to create contour lines that are effected by cliff faces and is there a way to automatically draw the cliff faces?
I've tried using the Contour with barriers tool in ArcGIS but can't seem to get it to work. I've downloaded the DEM Raster and can produce contours from that, just can't take it to the next step where the contours are effected by barriers.
I'm using both ArcGIS and QGIS.
